    Beschreibung: To obtain more information on the distribution of dinoflagellate cysts in Thai and Malaysian waters, the surface sediment samples of 48 stations in the Gulf of Thailand and the east coast of Peninsular Malaysia were collected by M.V. SEAFDEC during the research cruise in September 1995 and repeated again in April 1996. Cysts of 20 species belonging to Goniolacoid, Tuberculodinioid and Peridinioid were found in the surface sediments collected from both cruises. Spiniferites spp. (=Gonyaulax spp.) were the dominant cyst in Thai and Malaysian waters. No cysts of harmful species were observed during this study.

    Beschreibung: Due to gross over-exploitation and a paucity of adequate information on fishery oceanographic, environmental and biological conditions that sustain the fisheries of the South China Seas region, the fisheries have become greatly impoverished. The deficiency in scientific intelligence has also circumscribed all attempts at substantive and tangible planning or management of fisheries throughout the region. The NAGA Oceanographic Expedition of 1959-1961, organized jointly by the United States of America, The Kingdom of Thailand and the erstwhile Republic of Vietnam, achieved pioneering oceanographic work in the Gulf of Thailand and the South China Seas. This invaluable scientific data acquisition was not pursued for a number of reasons, and thus, a holistic and dependable profile of oceanographic conditions and their seasonal variations and patterns failed to develop. Perceiving the vital importance and the deficiency of fundamental information and data for fisheries planning and management, the SEAFDEC Training Department (TD) and the Marine Fisheries Resources Development and Management Department (MFRDMD), jointly launched an inter-Department Collaborative Research program in 1995, to evaluate the fisheries resources of the South china Sea as a basal objective in the development of sustainable fisheries.

    Beschreibung: Dissolved oxygen and carbonate system in seawater in the Gulf of Thailand and the east coast of Peninsular Malaysian September 1995 and April-May 1996 were determined. It was found that surface water was well in equilibrium with the atmosphere. The sub-pycnocline water in the Gulf had the chemistry that was distinctly different from the mixed layer as well as from sub-pycnocline water in the South China Sea near the mouth of the Gulf, even with the same depth. There were some evidences that intermediate water in the South China Sea might flow into the Gulf along the central axis and the coast of Vietnam and Cambodia, and exited the Gulf along the Thai-Malay Peninsular coast. The chemistry of deep water in the South China Sea off the coast of Western Malaysia varied its chemistry by a great deal among seasons which might be due to the prevailing monsoon. Seawater in the Gulf of Thailand and South China Sea was supersaturated with respected to the mineral calcite.

    Beschreibung: Investigations on horizontal and vertical distribution in levels of total organic matter contents (TOM), acid volatile sulfides contents (AVS), and water contents (WC) of bottom sediments from the eastern and western parts of the Gulf of Thailand and the eastern part of the Peninsular Malaysia have been carried out during 5-28 September 1995 and 24 April to 17 May 1996 by M.V. SEAFDEC. The overall results indicated comparatively low amount of organic matters and sulfides deposited in the sediments. Considering on the vertical profiles, coupled efforts of low rate of sedimentation of the organic matters and high rate of their decomposition should play an important role providing fast diagenesis of their organic substances. Nevertheless, the particulate matters which had settled onto the sea bed and formed the sediments can be remarkably observed to accumulate in two major zones in the Gulf of Thailand; one in the central part of the upper gulf (around Station 7) and another one in the western part of the gulf, near Samui Island (around Station 23). Such an accumulation pattern was considered to be directly controlled by the bottom topography and current effort. The accumulation of organic materials there also implied the mode of biological fishery resources. High abundant of organisms in the benthic community should be observed. Moreover, according to biogeochemical interaction between the sediment-water interface, phytoplankton production in the overlying water column should be enhanced and, consequently, a congregation of organisms in the upper trophic levels especially those of fish species were accordingly expected. Future assessment for development of the fishery resources in the Gulf of Thailand and the eastern part of Peninsular Malaysia has been discussed.

    Beschreibung: Surface sediment (0-2cm) from 23 stations in the Gulf of Thailand and the South China Sea were analysed for Polynuclear Aromatic Hydrocarbon (PAH), and Total Aliphatic Hydrocarbon (TAH). PAH was found to be in the range between 0.7047 mmg/g dry wt. (Stn 70) to 26.6066 mmg/g dry wt. (Stn 52) to 25.5314 mmg/g dry wt. (Stn 41). Long chain aliphatic hydrocarbon (n〉20) were found to be dominant species in the most of the sample.

    Beschreibung: A study on the macrobenthos profile was conducted using the research vessel MV SEAFDEC in almost all parts of the Gulf of Thailand and the East Coast of Peninsular Malaysia. A total of 44 stations were located within the Gulf of Thailand and 37 within that of East Coast of Peninsular Malaysia. Two cruises were carried out during the pre-and post-north-east monsoon. Macrobenthos showed greater density in Malaysian waters during the pre-monsoon period with 2500 individuals (at an average 67.6 individuals/m2) compared to the Gulf of Thailand which showed 860 individuals (average 19.5 individuals/m2). However, sampling after the monsoon has indicated quite the reverse, with 2680 individuals (60.9 individuals/m2) found in the Gulf of Thailand compared to 620 individuals (16.8 individuals/m2) in the East Coast of Peninsular Malaysia. All samples from both cruises were dominated by polychaete worms, followed by crustacea. Other groups such as echinoderms, molluscs, nemertians and sipunculids were also observed in lesser quantities. In terms of diversity, the Gulf of Thailand showed less families/taxa before the monsoon (with 20 families) than after the monsoon (with 35 families). The reverse holds true for the east coast of Peninsular Malaysia when 33 families were uncovered before the monsoon compared to 26 families after the monsoon. Among the dominant families/taxa were the polychaetes Cirratulidae, Orbiniidae, Eunicidae and Maldanidae; caridean shrimps and ophiuroids (brittle star).

    Beschreibung: The ecology of macrobenthic fauna in the Gulf of Thailand and the east coast of Peninsular Malaysia was studied for two periods of time at pre NE monsoon (4 Sep.- 4 Oct. 1995) and post NE monsoon (23 Apr. -23 May, 1996). It was found that the overall abundance of macrobenthic fauna presented the highest density at station 52 (920 ind. m-2). Polychaete was the dominant group in the benthic communities. The result of the survey of the ecology of benthic fauna shows that the fauna density increases with a decreasing water depth. Polychaete, Crustacea and Echinoderm groups displayed a marked change in density with the during period of the monsoon and the diversity index showed different patterns during the pre and post NE monsoon periods.

    Beschreibung: Net circulation in the three layers in the Gulf of Thailand 0-10 m, 10-40 m and 〉40 m were simulated by a hydrological model using tri-monthly average of observed temperature, salinity, depth and wind. Prevailing monsoon was an important factor controlling current speed and direction of water above the pycnocline (0-40 m). The water in the upper 10 m flew from the South China Sea during the Northeast Monsoon and opposite during the Southwest Monsoon. The water in the near surface layer in all simulations was replenished mainly by the opposite flow in the mid-depth layer and only slightly from the deep, nutrient enriched, water below 40 m. The true circulation gyre could not be seen in our simulations but different degrees of eddies and meanders were evident in almost all runs. These features could play very important roles in the distribution and dispersion of dissolved, particulate and biological species, including pollution and larvae, and deserved more in depth studies in the future.

    Beschreibung: Dissolved cadmium, copper, iron, lead and nickel in seawater at different depths were analyzed using the cobalt-APDC coprecipitation technique. The concentrations found were low and within the range found in natural seawater elsewhere. Terrestrial sources, especially near the head of the Gulf of Thailand and the Nakorn Sri Thammarat-Songkhla area on the Thai-Malay Peninsular, were clearly observed especially during the high runoff season. External input and horizontal dispersion dominated over internal recycling and removal in controlling concentration and distribution of iron and copper but it was the opposite for cadmium, nickel and lead where biological removal near surface and bottom regeneration might explain the nutrient type vertical profiles of these elements.

    Beschreibung: Joint collaborative research surveys in the Gulf of Thailand and the South China Sea around the east coast of Peninsular Malaysia during the pre northeast monsoon (4 September - 4 October, 1995) and the post northeast monsoon (24 April - 17 May, 1996) periods were carried out on board the MV SEAFDEC. The microplankton from the sampling stations consisted of more than 205 taxa consisting predominantly of blue green algae (2 species), diatoms (〉 120 species), dinoflagellates (〉 80 species) and microzooplankton (〉 30 groups). The dominant diatom species comprised of Chaetoceros lorenzianum, C. coastatum, Thalassionema frauenfeldii, Skeletonema costatum, Pleurosigma elongatum, Bacteriastrum comosun, Bacillaria paxillifera, Coscinodiscus jonesianus and Rhizosolenia calcar-avis. The genera Chaetoceros, Rhizosolenia, Coscinodiscus, Bacteriastrum and Ceratium were found to contain a wide range of species. Skeletonema bloom (1.12 x 106/m3; 47% of the total cell count) occurred around the Johore waters of the South China Sea. Dinoflagellate was also present during the premonsoon period, especially in offshore waters of the Gulf of Thailand and Terengganu nearshore waters of the South China Sea. The microzooplankton consisted of more than 30 species dominated by copepod nauplii while the foraminifera consisted mainly of the Globigerina species. The diversity index (H) and evenness index (J) values were usually high at stations near to the coast.

    Beschreibung: Current and circulation patterns for the area where water depth exceeded 500 m were calculated from geostrophic balance. Divergence and convergence inferred from horizontal circulation matched quite well with the observed vertical migration of the pycnocline, i.e. an indication of upwelling and downwelling. The spatial circulation pattern for July-August 1996 was quite different from that for May 1997, despite a generally similar prevailing wind. Eddies and meanders were the main features causing the difference. Interpretation of chemical and biological data of the area should take into consideration these local and sporadic physical phenomena.

    Beschreibung: Surficial investigation of bottom sediments was conducted within the waters off the coast of Sabah, Sarawak and Brunei Darussalam. Two sampling of bottom sediments were conducted, one before (September 1996) and one after (April 1997) the Northeast monsoon period, which normally lasts from November to February annually. During the pre-monsoon cruise, fifty-one samples were collected while 52 samples were collected during the post-monsoon exercise. The collected samples were analysed for their sedimentological characteristics of mean, sorting, skewness and kurtosis. Analyses revealed that the post-monsoon sediments are finer, better sorted in arrangement, more symmetrical and less peaked than the pre-monsoon sediments. Deeper water sediment shows the same characteristics as described above when compared to shallow water sediments. In general, the near-shore sediments are coarsest, more poorly sorted, more positively skewed and most peaked in characteristics when compared to the mid-shore and off-shore sediments.

    Beschreibung: Depth integrated biomass of phytoplankton in the southern part of the South China Sea off Sarawak, Brunei Darussalam and Sabah in July 1996 and May 1997 was represented by in situ fluorescence. The total biomass in the study area was not much different between the 2 surveys. However, the spatial distribution of biomass clearly showed a unique pattern for each cruise. In overall, the local biomass per unit area did not correlate strongly with surface mixed layer thickness and sea surface temperature, two indicators of upwelling used in this study. Yet, anomalously high biomass of phytoplankton found in the vicinity of Stations 37 and 38 for both survey periods could be partially related by upwelling nearby.

    Beschreibung: Study on nutrient diagenesis and physico-chemical characteristics of bottom sediments of the Sabah, Sarawak and Brunei Darussalam waters had been carried out under the ongoing SEAFDEC Collaborative Research Project. The results indicated that organically enriched offshore sediments consisted high levels of pore water nitrate and phosphate concentrations. For the whole study area, the levels of nitrate and phosphate concentrations in pore water were in the ranges of 0.05 to 77.12 µg at NO3--N/L and 0.07 to 13.13 µg at PO43--P/L, respectively. Upward diffusive fluxes of pore water nitrate widely changed in stations. At the nearshore area, the fluxes of pore water nitrate had an average of 26.5 mg at NO3--N/m2/d and were about one order of magnitude higher than those of phopsphate. However, phosphate upward fluxes were apparently high at deep areas off Sabah. Pore water ammonium concentrations were commonly very low but tended to be more accumulated at nearshore organically enriched areas. The ammonium concentrations for the whole study area ranged from non-detected level to 81.76 µg at N/L. The nearshore stations showed very high upward fluxes of ammonium, which were nearly 10 times higher than those of nitrate and phosphate. Sedimentary organic levels were comparatively high in two distinct regions; (I) a shallow nearshore region of Sarawak, and (II) a deep offshore region of Sabah and Brunei Darussalam. The sources of organic materials settled in Regions (I) and (II) were suggested to be derived from different origins. The Northeast monsoon can somewhat enhance organic accumulation in the nearshore region. Overall our results obtained from this study had been used to characterize the bottom sediments into three distinct regions and discussed for further fishery resource development and management.

    Beschreibung: The trace metals composition of surface sediment of the South China Sea off Sarawak, Sabah and Brunei were measured. Total metal concentrations in the 63 µm fraction are reported in this study. For the pre-monsoon cruise, the metal concentrations ranged between 1.01 – 13.0 µgg-1 Pb, 8.28 – 99.8 µgg-1 Cu, 27.8 – 137.0 µgg-1 Zn, 10.1 – 75.7 µgg-1 Cr, 175 – 1166 µgg-1 Mn, 0.83 – 4.57% and Fe 0.16 – 2.25%. The range of metal concentrations measured in the post-monsoon cruise varied between 1.63 – 18.9 µgg-1 Pb, 7.52 – 38.0 µgg-1 Cu , 14.4 – 105 µgg-1 Zn, 19.6 – 87.6 µgg-1 Cr, 157– 1890 µgg-1 Mn, 1.37 – 9.83 % Al and 0.51 – 4.47 % Fe. The distribution of metals in the sediment showed different patterns between the pre-monsoon and the post-monsoon periods. The Rajang River seems to be one of the major factors affecting the distribution of metals in the seabed off Sarawak.

    Beschreibung: The distribution of ortho-phosphate in the South China Sea off Sarawak, Sabah and Brunei Darussalam waters was studied in the SEAFDEC Interdepartmental Collaborative Research Survey: Area II. The samples were collected by M.V. SEAFDEC on 8 July to 3 August 1996 (pre monsoon period) and 1 to 24 May 1997 (post monsoon period). Seventy-nine stations were established in this study. The average concentration of ortho-phosphate of the pre monsoon period at 0-1 meter, 10 meter, 20 meter, 50 meter, 100 meter and 200 meter, 500 meter, 1000 meter and 1500 meter depth of the third survey cruise were 0.14 μM, 0.09 μM, 0.10 μM, 0.09 μM, 0.50 μM, 0.90 μM, 1.94 μM, 2.59 μM and 3.10 μM respectively. The average concentration of ortho-phosphate of the post monsoon period at 0-1 meter, 10 meter, 20 meter, 50 meter, 100 meter, 200 meter, 500 meter, 1000 meter and 1500 meter depth were 0.24μM, 0.28 μM, 0.20 μM, 0.25 μM, 1.15 μM and 2.27 μM, 4.13 μM, 5.19 μM and 5.41 μM respectively. The ortho-phosphate levels were low in the surface water and increase with depth. The results indicated that the deep water of the study area is very rich in phosphate.

    Beschreibung: The studies were carried out between 9th July and 3rd August 1996 (3rd cruise) and 30th April and 30th May, 1997 (4th cruise) in the Exclusive Economic Zone of Sarawak and the western part of Sabah. The species distribution, abundance, composition and length-weight relationships of some commercially important fish were investigated and compared for both cruises. The results indicate that the overall catch rate ranged from 3.5 to 194 kg/hr and averaged at 55.9 kg/hr during the 3rd cruise. For the 4th cruise, it ranged from 10.9 to 90.5 kg/hr and averaged at 50.2 kg/hr. During the 3rd cruise, 46.9% of the catch were dominated by demersal fish followed by 41.6% trash fish, 7.8% pelagic fish and 3.1% cephalopod. Priacanthidae was the most dominant family, which made up of 14.1% of the catch followed by Nemipteridae (10.8%), Carangidae (5.0%), Lutjanidae (3.7%) and Mullidae (2.1%). The ten most dominant species found during the 3rd cruise were 1. Priacanthus macracanthus (13.2%), 2. Nemipterus bathybius (3.3%), 3. Abalistes stellaris (2.8%), 4. Arius spp.(2.5%), 5. N. nematophorus (2.2%), 6. Gymnocranius griseus (1.9%), 7. N. marginatus (1.7%), 8. Sepia spp. (1.7%), 9. Decapterus spp. (1.6%) and 10. Carcharhinus spp (1.3%). During the 4th cruise, the family Nemipteridae (12.7%) formed the most dominant fish family followed by Carangidae (8.7%), Mullidae (7.1%), Lutjanidae (4.9%) and Priacanthidae (2.2%). The ten most dominant species were: 1. Loligo spp. (5.7%), 2. Nemipterus bathybius (4.2%), 3. Abalistes stellaris (4.0%), 4. Upeneus moluccensi (3.8%), 5. Nemipterus nemurus (3.8%), 6. Gymnocranius griseus (3.2%), 7. Carangoides malabaricus (3.2%), 8. Plectorhynchus pictus (3.1%), 9. Upeneus bensasi (2.4%) and 10. Arius spp. (1.8%). The morphometric study shows that the population of fish are normally distributed.

    Beschreibung: Acoustic resource surveys were conducted by M/V SEAFDEC off Sarawak, Brunei and the east coast of Sabah from July 10 to August 2, 1996 for pre-NE monsoon season and from May 1 to May 24, 1997 for post-NE monsoon season, using the scientific echo sounder FQ-70, developed by Furuno Electric Co. Japan. Collected raw values of backscattering strength (SV) from the 200 kHz transducer were carefully corrected and filtered to eliminate the influence of plankton. These corrected SV values were divided into pelagic and demersal fish, and were used to estimate the biomass of pelagic and demersal multi-species in the limited coastal waters off Sarawak. Decapterus macrosoma for pelagic fish and Priacanthus macracanthus for demersal fish were selected as representative species, based on the fisheries statistics, landing place survey, and research vessel survey in order to estimate biomass. The standard length (SL) and weight of these representative species were obtained from research vessel survey and supported by previous literatures. Target strength (TS) of these representative species were calculated using formula TS = 20 log(SL) - 66. The distribution of the SV values for pelagic fish showed distinct difference between pre and post Northeast (NE) monsoon seasons along the coastal waters. Greater concentrations of SVs were observed from depth 100 and 200m on the continental shelf along the survey area for both the seasons. The estimated biomass of multi-species fish off coastal Sarawak waters for the pre and post NE monsoon seasons was 120,000 tonnes (100,000 tonnes of pelagic fish and 2x105 tonnes of demersal fish) and 470,000 tonnes (360,000 tonnes of pelagic fish and 110,000 tonnes of demersal fish), respectively. Estimated Maximum Sustainable Yield (MSY) was 83,000 tonnes for pelagic fish and 31,000 tonnes for demersal fish when using Cadima’s model.

    Beschreibung: This study provides new information on the physical characteristics of water masses in Sabah and Sarawak waters. The aim was to determine the effect of Southwest (SW) monsoon on the variability of water masses, in Sabah and Sarawak waters. Physical characteristics data were obtained using an instrument called “Integrated Conductivity Temperature Depth” (iCTD), during the third (July 1996) and fourth (May 1997) cruises of the MV SEAFDEC research vessel, conducted during the SW monsoon season. Vertical distributions and profiles of temperature, salinity and density were analyzed and their variations between the two cruises compared. It is concluded that there were no great variations of temperature, salinity and density values in the study area, during both cruises. This is because both cruises were conducted during the SW monsoon season. However, variations of temperature, salinity and density values were observed between shallow and deep waters, as well as coastal and offshore waters. Based on their vertical distributions and profiles obtained during the two cruises, water properties in shallow waters were found to vary slightly from the deeper ones. As a result, in the southern tip of the South China Sea, where the water was shallow, its properties here differed a little from the rest of the study area. This was due to the pronounced mixing effect of surface waves in shallow waters. At the same time, lower salinity and consequently, lower density values were detected in coastal waters, resulting from of the influx of freshwater from Sabah and Sarawak rivers during this monsoon season.

    Beschreibung: The macrobenthic fauna in the South China Sea (Sarawak, Brunei and Sabah) was surveyed during pre NE monsoon (4 Jul.- 8 Aug. 1996) and post NE monsoon (25 Apr.-31 May 1997). Over 90 species were collected by Smith-McIntyre grab of 47 stations. The overall density of macrobenthic fauna in Sarawak, Brunei and Sabah area was 100 ind. m-2 on average in the pre NE monsoon and 167 ind.m-2 on average in the post NE monsoon. Most species were carnivore/scavengers followed by deposit-feeder and fewer suspension-feeder or herbivores both in the pre and post NE monsoon. There was a marked seasonal variation in faunal composition between the pre and post NE monsoon. During the pre NE monsoon polychaeta was the most abundance followed by crustacea while during the post NE monsoon crustacea was the most abundance followed by polychaete and the remaining groups of macrobenthic fauna which were poorly represented in the survey areas both in the pre and post NE monsoon periods. All the diversity indices decline from the pre to post NE monsoon.

    Beschreibung: Fish larvae samples were obtained from 79 stations in South China Sea of the Sarawak , Brunei and Sabah during the pre northeast monsoon season (August - September 1996) and the post northeast monsoon (April - May 1997). The standard larvae net and bongo net were used for the surface and oblique sampling. The specimens were identified which comprise of 112 families and 186 species of fish larvae observed from both cruises. For the pre northeast monsoon sampling there were 5,156 individuals observed from 86 families and 125 species in the surface horizontal haul and 16,277 individuals from 96 families and 149 species in the oblique haul. The post northeast monsoon collection showed 6,595 individuals from 79 families and 114 species collected in the surface horizontal hauls and 24,450 individuals from 94 families and 158 species observed in the oblique hauls. From the surface horizontal sampling, the abundant larvae observed were Stolephorus sp., Sardinella sp., Upeneus sp., Myripristis sp., Holocentrus sp., Gobiidae, Decapterus sp. and Diaphus sp. Specimens from the oblique hauls, Gobiidae, Bregmaceros rarisquamosus, Nemipterus sp., Stolephorus sp. and Callionymus sp. were the most species observed abundant in the collection. The mesopelagic fish larvae, Hygophum sp., Myctophum sp., Pollichthys sp. and Lampadena sp. were found abundant in the oblique specimens in the deep sea stations. The larvae were collected in more abundant during the early morning, night time and cloudy day sampling.

    Beschreibung: Three of the 20 species in the genus Trachinotus, in the jack family, Carangidae, are found in Florida waters. These are Florida Pompano (T. carolinus), Permit (T. falcatus), and Palometa (T. goodei). Florida Pompano is a coastal pelagic species found in estuarine and marine waters; it spawns in multiple batches in offshore waters. Permit is the largest and longest lived of the three species and also spawns offshore in multiple batches, near reefs. As adults, Permit can be found nearshore and offshore and are often associated with reefs, but as juveniles they are common estuarine inhabitants. Palometa is a marine species, similar in size to Florida Pompano, and has the widest latitudinal distribution of the three species. Palometa spawn in offshore waters throughout the year with two peaks of activity. All three species support commercial or recreational fisheries on both the Gulf of Mexico coast and Atlantic coast of Florida. Very little has been done to evaluate movement patterns of Trachinotus species. Based on a few tagging studies, it appears that Pompano do not travel far from coastal waters. The only preliminary investigation of genetic stock structure for the Florida Pompano population from Tampa Bay, FL, and Puerto Rico was based on microsatellite markers developed for the Pompano. The report’s key conclusion was that Pompano from Puerto Rico and from Florida belong to two highly distinct genetic stocks. This study was conducted to re-examine, using different microsatellite markers, the genetic status of Pompano stocks in Florida and Puerto Rico. The objectives of this study, therefore, were the following: 1) to develop microsatellite markers for Permit; 2) to cross-amplify the markers in Pompano and Palometa; and 3) to use these markers to confirm the status of Puerto Rico Pompano as a novel genetic stock using the methods of Bayesian population assignment, phylogenetic clustering, and factorial correspondence analysis. ... Three methods were used to investigate the relationship among the taxa using the microsatellite genotype data obtained from the samples. The results from the three analytical methods, based on Bayesian population assignment tests, phylogenetic clustering, and factorial correspondence analysis of genetic relationships among the four Trachinotus samples, showed that Florida and Puerto Rico Pompano samples belong to two highly distinct gene pools. But other multiple molecular tools, particularly nuclear-DNA sequences from many introns, and nonmolecular tools, such as morphological and meristic data, should be used together to determine species-level categorical designation for the Puerto Rico Pompano.

    Beschreibung: The shoaling and bank erosion at Ponce de Leon channel, Punta Gorda, Florida, havecaused concern of harming the mangrove community along the channel. Three factorswere identified that could contribute to the bank erosion of Ponce channel. Theyare tidal induced current, wind waves penetrating from the Charlotte Harbor, andwakes caused by boat traffic. According to the field experiments and numericalmodeling studies, it was determined that the combined wind wave and tidal currentforce is the major cause to the bank erosion. Wind wave appears to play a moreimportant role because of its dynamic nature. For the present cross-sectionalchannel condition the tidal current alone is only a moderate erosional force.It was also found that reopening the barge canal would cut the tidal currentstrength in the Ponce channel by a half. This current reduction would reduce butnot eliminate bank erosion in the lower reach as the wind-wave induced force willremain to be an important erosional factor.A number of remedial alternatives were given in the report. The most direct methodis to provide bank protection. The extent of the protection depends upon theextent of wind wave penetration which could be as deep as 150 m into the channelunder the present channel entrance condition. (This document has 49 pages. )

    Beschreibung: Abstract of Thesis Presented to the Graduate Schoolof the University of Florida in Partial Fulfillment of theRequirements for the Degree of Master of EngineeringVIDEO MONITORING TECHNIQUES IN THECOASTAL ENVIRONMENTByThe field of coastal engineering has primarily utilized traditional measurementtechniques such as boat surveys and beach profiles. Aerial photography has played amajor role in the mapping of coastlines and ocean currents. More recent technology hasprovided the ability to make field measurements with precision electronicinstrumentation, but the problem of making large-scale measurements within economicbounds remains. The video revolution and, in particular, desktop video has greatlyenhanced the ability of scientists and engineers to visualize events over greater periods oftime and larger scales than ever before.The uses of video, benefits, shortcomings, and future expectations are presentedas applicable to the field of coastal engineering. This feasibility study incorporates someapplications which have previously been explored, as well as others which result fromtwo unique video data sets that were collected between 1991 and the present.

    Beschreibung: A method of predicting equilibrium scour depths around multiple pile structuresbased on pre-scoured bottom shear stress was developed in this study. It washypothesized that a relationship exists between the pre-scoured bottom shear stress andthe equilibrium scour depth. A series of hydrodynamic tests were conducted in whichnear-bottom flow measurements were made in the vicinity of a variety of multiple pilestructures. The distribution of bottom shear stress was estimated from these flowmeasurements. Scour tests were then made in the same flume using the same structures.A simple relationship between the equilibrium scour depth and the pre-scoured bottomshear stress was formulated and the data from the two sets of experiments were used tocalibrate and test the formulation. The formulation gives reasonable predictions for therange of conditions tested. The approach appears promising as an alternative way of estimating equilibrium local scour depths for complex multiple pile structures. Inaddition, a number of interesting and useful findings were made regarding the rate atwhich a local scour hole forms near complex structures. (Document contains 146 pages.)

    Beschreibung: This is the first of a pair of reports documenting the effects of storms on barrier island systems.The present report (Volume 1) investigates storm effects on natural island conditions whereasVolume 2 addresses the effects of seawalls. With the aim of simulating the effects of overwashon barrier islands and characterizing their response, a series of nine experiments was conductedat the Coastal Engineering Laboratory of the University of Florida. The barrier island wassimulated by a 400 feet wide (prototype units) horizontal crest and an initially planar (1:19)beach. The effects of various storm surge levels and accompanying overtopping were investigated.Experiments were conducted with both regular and irregular storm waves. Regularwaves without overtopping caused the formation of a substantial berm in the swash zone and aprominent longshore bar offshore. Increasing degrees of overtopping resulted in substantial lossof sand from the barrier island system. The longshore bar was considerably more subtle for thehighest water level tested (11.5 ft. above mean sea level). Simulation of a storm-surge hydrographwith rising and falling water levels indicated that the presence of the bar tends to occuronly during a relatively steady or slowly changing water level. The experiments with irregularwaves were conducted with reasonably similar wave heights and carrier periods as those withregular waves. The major difference was in the characteristics of the longshore bar response. Incomparison with cases with regular waves, the bar was less distinct without overtopping, subtlewith minimal overtopping and absent in cases with substantial overtopping. These experimentsseem to indicate that offshore bars are simply break-point bars which require a fairly steadybreak-point and undertow (return of mass transport) for optimal formation.

    Beschreibung: This report presents results of the experiments of the existing inlet and eightstructural alternatives to the Sebastian Inlet from a movable bed model. It is intendedto find solutions for improvement of boating safety and protection of beaches adjacentto the inlet. Based upon the experimental results from here and the fixed bed modelstudy, which is summarized in Part I report, an optimum structural modification planwas then recommended providing a general frame of improvement scheme.The research in this report was authorized by the Sebastian Inlet District Commissionof September 15, 1989. The University of Florida was notified to proceedon November 14, 1989. The study and report were prepared by the Department ofCoastal and Oceanographic Engineering, University of Florida. Coastal TechnologyCorporation was the technical monitor representing the Sebastian Inlet District. (Document has 109 pages.)

    Beschreibung: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.

    Beschreibung: This is the second of a pair of reports documenting the effects of storms on beach systemsincluding the presence of seawalls. With the aim of simulating the effects of overwash onbarrier islands with seawalls and characterizing their response, a series of eight experimentswas conducted at the Coastal Engineering Laboratory of the University of Florida. The barrierisland was simulated by a 400 feet wide horizontal crest and an initially uniform mildly-sloped(1:19) beach. The effects of positioning the seawall at two different locations as well as the effectsof various storm surge levels and accompanying overtopping were investigated. Experimentswere conducted with both regular and irregular storm waves. With the seawall located at theslope break between the crest and the sloping beach of the barrier island, and the crest of theseawall just submerged in sand, the effects on the sediment transport process were found to beminimal. For the same position of the seawall but with the crest of the seawall raised above thesurrounding ground level, overtopping caused washover of sand indicating substantial transportin suspension. Increased levels of overtopping tended to accentuate bed profile changes butsupress bar formation (as did irregular waves). Positioning the seawall at the Mean Sea Levelshoreline caused significant scour both immediately landward as well as immediately seawardof the seawall. A prominent scour trough developed further seaward. The longshore bar washighly three-dimensional. It appears that seawalls need to be located adequately landward of theshoreline to discharge their function effectively without adverse effect to the beach. In addition,concerns for safety warrant the presence of an adequate buffer-zone between the seawall andthe upland property. (61 pp.)

    Beschreibung: The genus Synalpheus Bate, 1888, is one of the most diverse and widely distributed generaof caridean shrimps in the world. Often known as snapping shrimps because of the popping soundmade by the major first pereopod when the chela is closed rapidly, members of this genus areimportant components of coral reef and live bottom communities in all tropical and subtropical seas.The Gambarelloides group (a well-defined, homogeneous group within the genus but lackingformal subgeneric status) contains over half the described species of Synalpheus in the Gulf ofMexico and Caribbean. Its many species are distinguished from each other by subtle, and oftenvariable, characters. Accurate inventories of the Gulf fauna have been handicapped by difficulty inseparating these shrimps at the specific level. Distributional data, diagnoses, and references toeach of the 19 species of the group from the Western Atlantic Region are presented in this report.The 11 species known from the Gulf of Mexico are illustrated. Details of specific ecological associations,morphological variation, and life history strategies are also summarized. (Document has 125 pages.)

    Beschreibung: Current plant canopy wind flow models require three aerodynamic parametersto predict the effects of wind on sand transport--the plant drag coefficient, Cd, the leafarea density profile, LAD, and the turbulent eddy transfer coefficient, 6,. The LADand Cd characterize the plant canopy and its effects on air flow and, prior to thisstudy, data on these parameters for dune vegetation did not exist. The purpose of thisstudy was to design and test a methodology for measuring the wind drag coefficient ofcoastal dune plants. The objectives were 1) to measure and record the parametersneeded to calculate Cd, namely, the force, relative velocity and air temperature; 2) tomeasure the leaf area density of sea-oats; 3) to validate the method by measuring thequantities needed to compute the drag coefficient for a right circular data exists; and 4) to explore the Reynolds number dependence of the canopy dragcoefficient.

    Beschreibung: Management programs that address scarringof seagrasses should be based on an approach thatinvolves (1) education, (2) channel marking,(3) increased enforcement, and (4) limited-motoringzones. Aerial monitoring and photography ofthe managed area are essential in evaluating theeffectiveness of a program. Management programsthat use this multifaceted approach have beeninstituted by a few local governments and at severalstate parks. Initial results of the programsindicate that in some areas seagrass scarring hasbeen reduced but that in other areas emphasis mayneed to be increased on one or more of the componentsof the four-point approach. A statewidemanagement plan is needed to address the mostegregious scarring over large areas that may bedifficult to regulate at the local-government level.

    Beschreibung: With the rapid growth and development of barrier islands, understanding the long-termstability of these islands is an integral part of future coastal planning. The overwash process isthe largest influence on the long-term stability of these islands and thus a correspondingunderstanding is of major importance. A laboratory experiment was undertaken to physicallymodel the wave and current forcing as they pertain to the overwash process. The physical modelwas subjected to various storm conditions common to the occurrence of the overwash.Combinations of wave height, wave period, and overwash depth were tested in an attempt toisolate the significant parameters. Water surface gradients were also applied to observe theirinfluence on the overwash process. Wave height, current, and bed profile measurements weretaken at different locations throughout the tank. In addition, wave height transformationmodeling and mean current prediction were performed and compared to the laboratory results inan attempt to model the overwash process through computer simulations.The experimental results demonstrate that the water surface gradient is the mechanismfor transporting large quantities of sand on to and over barrier islands. In addition, two otherconclusions were drawn about the overwash process: 1) the overwash depth plays an importantrole in determining the overwash velocity and hence the amount of sand deposited on the barrierisland. 2) There seems to exist a correlation between the strength of the return flow and barformation.It was also determined that modeling the wave height transformation during the overwashprocess is possible if the model is expressly written for the overwash process and not for nonoverwashingcases. The method utilized to predict the mean currents during overwash was notable to predict their strength but was able to substantiate the correlation between return flow andbar formation. As a result of overwash, the increased shoreward mass transport and reducedreturn flow in the water column are able to initiate and sustain a shoreward sediment transport.Finally, it was concluded that in all likelihood only "significant" overwash events affect the longtermstability of the barrier islands.

    Beschreibung: This report is to document the programs my colleague and I developed for computingtime-dependent nearshore hydrographic changes including beach profile responses.The time scale of the model is suitable for storm events to seasonalchanges, currently up to one year period. The model is very stable and is capableof handling complicated topographies including inlets and irregularly-shapedstructures such as curved jetties and breakwaters.The purpose of three-dimensional models is to predict the change of bottomtopography from the spatial distribution of the sediment transport rates, which areevaluated from the nearshore wave and current fields computed point by point insmall areas defined by a horizontal grid placed over the region of interest. Modelsof 3-D beach topography change require much fewer idealizations than do the linemodels. (Document has 43 pages.)

    Beschreibung: The objectives of this study were 1) to determine the maximum structure-inducedlocal sediment scour depths for the proposed bridge piers for the Merrill BarberBridge over Indian River on.State Road 60 in Indian River County, Florida and 2) todetermine the feasibility of predicting equilibrium local scour depths near complexmultiple pile bridge piers from bottom shear stresses on the prescoured bed. Aseries of hydrodynamic tests were conducted in a laboratory flume (100 ft long x 8 ftwide x 2 ft deep) where flow velocities near model piers were measured with a twocomponent constant temperature anemometer at a height of 3 mm above the bed. Bottomshear stresses were then estimated from the flow measurements. The piers (which are1/15 scale models of proposed Merrill Barber Bridge piers) consisted of thirtysixsquare piles (3 columns of 12) and a pile cap that was positioned at differentelevations above the bottom. Two different pile cap shapes were also considered. Asimple relationship between the prescoured bottom shear stress and the equilibriumlocal scour depth was postulated.Sediment scour tests were then conducted in the same flume with the samemodels. The average duration of these tests was 28 hours. Scour depths weremeasured periodically throughout these tests using an acoustic transponder. Thescour measurements were used 1) to establish the maximum scour depths for the MerrillBarber Bridge piers and 2) to calibrate and test the scour-shear stress relationship.Even though the range of conditions tested was somewhat limited, the approach appearspromising and should be pursued further. A number of interesting findings were maderegarding the rate at which scour occurs in these complex structures. (Document contains 134 pages.)

    Beschreibung: Part I. Relationships between the rate of bed fluidization and the rate of wave energy dissipation, by Jingzhi Feng and Ashish J. Mehta and Part II. In-situ rheometry for determining the dynamic response of bed, by David J.A. Williams and P. Rhodri Williams.A series of preliminary laboratory flume experiments were carried out to examine the time-dependentbehavior of a cohesive soil bed subjected to progressive, monochromatic waves. The bed was an aqueous,50/50 (by weight) mixture of a kaolinite and an attapulgite placed in a plexiglass trench. The nominal bedthickness was 16 cm with density ranging from 1170 to 1380 kg/m 3, and water above was 16 to 20 cmdeep. Waves of design height ranging from 2 to 8 cm and a nominal frequency of 1 Hz were run fordurations up to 2970 min. Part I of this report describes experiments meant to examine the rate at whichthe bed became fluidized, and its relation to the rate of wave energy dissipation. Part II gives results onin-situ rheometry used to track the associated changes in bed rigidity.Temporal and spatial changes of the effective stress were measured during the course of wave action,and from these changes the bed fluidization rate was calculated. A wave-mud interaction model developedin a companion study was employed to calculate the rate of wave energy dissipation. The dependence ofthe rate of fluidization on the rate of energy dissipation was then explored.Fluidization, which seemingly proceeded down from the bed surface, occurred as a result of the lossof structural integrity of the soil matrix through a buildup of the excess pore pressure and the associated loss of effective stress. The rate of fluidization was typically greater at the beginning of wave action andapparently approached zero with time. This trend coincided with the approach of the rate of energydissipation to a constant value. In general it was also observed that, for a given wave frequency, the largerthe wave height the faster the rate of fluidization and thicker the fluid mud layer formed. On the otherhand, increasing the time of bed consolidation prior to wave action decreased the fluidization rate due togreater bed rigidity. Upon cessation of wave action structural recovery followed.Dynamic rigidity was measured by specially designed, in situ shearometers placed in the bed atappropriate elevations to determine the time-dependence of the storage and loss moduli, G' and G", ofthe viscoelastic clay mixture under 1 Hz waves. As the inter-particle bonds of the space-filling, bedmaterial matrix weakened, the shear propagation velocity decreased measurably. Consequently, G'decreased and G" increased as a transition from dynamically more elastic to more viscous responseoccurred. These preliminary experiments have demonstrated the validity of the particular rheometrictechnique used, and the critical need for synchronous, in-situ measurements of pore pressures and modulicharacterizing bed rheology in studies on mud fluidization.This study was supported by WES contract DACW39-90-K-0010.(This document contains 151 pages.)

    Beschreibung: Turbidity is a measure of the clarity of water. Turbidity depends upon thescattering and absorption of light by suspended particles. The focus of this study wasto obtain quantitative measurements of turbidity in the nearshore zone, along withmeasurements of associated wave parameters and currents occurring naturally andduring a beach nourishment project. The objectives were to make quantitative andqualitative comparisons between natural events and those induced by the dredge andfill operations, as well as assess the long term effects of the nourishment, uponturbidity.In-situ measurements of turbidity and wave climate were obtained at two shorenormal sites off the coast of Hollywood, Florida, from January, 1990 to April, 1992.The beaches adjacent to the communities of Hallandale and Hollywood wererenourished during the summer of 1991. Thirty minute in-situ observations wererecorded in burst mode every four hours at a frequency of four hertz. Analysis of thedata resulted in descriptions of the wave climate as well as statistics of turbidity for each observation.

    Beschreibung: The mechanism by which fluid mud is formed by water wave motion over coastal andestuarine cohesive soil beds is of evident interest in understanding and interpreting themicrofabric of flow-deposited fine sediments in shallow waters, and hence the erodibilityof muddy beds due to hydrodynamic forcing. This study investigated water wave-inducedfluidization of cohesive soil beds composed of a 50/50 (by weight) mixture of a commercialattapulgite and a kaolinite in a laboratory flume. Temporal and spatial changes of theeffective stress were measured during the course of wave action, and from these changesthe bed fluidization rate was calculated. A previously developed hydrodynamic wave-mudinteraction model of the two-layered water-mud system was employed to study the natureand the degree of wave dissipation, in terms of energy dissipation rate, during the bed fluidizationprocess. By evaluating the mud rheological properties separately, a mud viscositymodel was developed, which was then used in conjunction with the wave-mud interactionmodel to obtain an effective sheared thickness of the bed resulting from wave action. Thisthickness, considered to be a representative of the fluidized mud thickness, was comparedwith the latter obtained from pressure measurements. Also, through this wave-mud modelthe relationship between the rate of fluidization and the rate of wave energy dissipationduring fluidization was examined. In general, for a given wave frequency, a larger wave fluidized the bed at a faster rateand to a greater depth than a smaller one. Furthermore, increased bed consolidation timedecreased the rate of fluidization due to increased mud rigidity. The rate of bed fluidizationwas typically greater at the beginning of wave action and decreased with time. Eventuallythis rate approached zero, while in some cases the wave energy dissipation rate approached aconstant value, which increased with wave height. As the fluidization rate approached zero,there appeared to occur an equilibrium value of the bed elevation, and hence a fluid mudthickness, for a given wave condition. During the fluidization process the bed apparentlylost its structural integrity by loss of the effective stress through a build-up of the excesspore water pressure. After wave action ceased, the bed structure exhibited recovery bydissipation of the excess pore water pressure.Further studies will be required in which the hydrodynamic model must be improved viaa more realistic description of mud rheology and relaxation of the shallow water assumption,and better pressure data must be obtained than in the present study. Nevertheless, thisinvestigation has been instructive in demonstrating relationships between the degree of mudfluidization, wave energy dissipation and bed consolidation time, and thus offers insight intoan important mechanism by which coastal and estuarine muds are eroded by wave action.

    Beschreibung: This thesis examines the historical shoreline response to inlet modifications and sealevel rise. Inlet modifications are considered to be the geographic stabilization and training(through the use of structures) of natural inlets and the creation and further modification ofartificial inlets. Shoreline response to natural and artificial processes must be understood inorder to predict the performance of the coastline. The tendency for creating and modifyinginlets increases as industry and population growth demands. Sea level rise is a natural processwhich cannot be controlled at this time. Current theoretical approaches to predictingshoreline response indicate that sea level rise and inlet modifications can cause substantialshoreline impact. Florida, with roughly a century of shoreline position and relative sea leveldata, provides a basis for examining past trends and comparing them with theory.The shoreline of Florida was found to be accreting with the greatest accretion alongthe east coast. Shoreline responses within the boundaries of the erosional influence of inletsdue to their creation and/or modification were examined for 19 inlets around the coast ofFlorida. The differences in the shoreline response before and after the initial modification ofeach inlet show the erosional strain that inlets apply on the nearby shoreline. The effect onshoreline response due to the human intervention (unnatural processes) of modifying inletswas isolated and examined. The shoreline response due to this "human intervention" was erosional, thereby showing the negative impact that modified inlets have on shorelines. Thisinduced erosion is responsible for the loss of roughly 21.6 million cubic yards of sand from theshoreline that is within the erosional influence of Florida's east coast inlets. Combining theshoreline changes due only to natural processes with sea level rise data allows for comparisonwith the commonly accepted Bruun Rule for shoreline response as a result of a changingsea level. This comparison and the effects of including a lag time between a rise in sea leveland a change in shoreline along the east coast of Florida during the last century show noagreement with the Bruun Rule and no correlation with a specific lag time.
