    Beschreibung: The first year of the New England Regional Fisheries Management Council has been marked by its experimental aura. Neither the Council nor the various sectors (representatives of the Federal and State agencies, members of the fishing industry, the public at large) were clear as to exactly what they were to do and how they were to do it--except in the broadest, most flexible (ambiguous?) terms. This created certain operational difficulties, and confusion for those whose livelihood was affected by the Council's operation. This latter group, particularly the fishermen, knew little of what went on, save in terms of the 'public facet of the Council--i.e., that portion of the Council's performance which occurred during the monthly meetings which were open to the public and which, supposedly, received public input at that time. This study defines that public face, deliberately avoiding the presentation of any data which was not accessible to the average audience participant, in an attempt to present some of the behavior which all participants demonstrated and which generated responses and reactions on the part of the other sectors. It uses standard anthropological techniques of data gathering and analysis to show the degree to which impression management on the part of all the actors operated in a systematic fashion to produce action, reaction, and counter-action. Particularly emphasized is the communication aspects.

    Beschreibung: Fish and fishermen appear to be in a serious decline in New England. The haddock are overfished, inshore herring stocks are depleted, yellowtail flounder and lobster are scarce. The popular image is of grizzled fishermen, their boats chipped, scarred, old-fashioned hulks of wood tied up two and three abreast along the rotting wharves and piers of New England's depressed port towns. In this research project, we wanted to determine the state of the New England fishing industry and to propose acceptable methods for the management of the fishery. During our early discussions with the fishing industry people, we mentioned that we were interested in limited effort programs as they might be applied to New England fishermen. We carefully, and probably tediously, explained the "theory of limited effort" and we were generally thought to be daft. We were told we had things backwards--that the fishing industry needed more fish, more men, more boats - and that the way to accomplish this was to get a 200-mile fishing limit and kick the foreigners out. One of these wishes has come true - in the spring of 1976, P.L. 94-265 established a 200-mile fishing zone off the United States, with regional management councils to make management plans and allocate the resources first to United States fishermen, with surpluses to foreign fishermen.

    Beschreibung: The NOAA National Underseas Research Program at Rutgers University is establishing a Long-term Ecosystem Observatory off New Jersey in 15 meters of water. As part of a bottom boundary layer study at this site, WHOI deployed a bottom instrument frame during the winter of 1993-94. The bottom instrument carried a current meter, a vertical array of optical back scattering sensors, temperature, pressure and conductivity sensors and an Acoustical Backscattering Sensor. The deployment was partially successful as the acoustic system failed. The other instrumentation worked well for 3 weeks returning data on winter conditions at the site. The extreme winter waves ended the experiment by tipping the instrument over on its side. The optical instrumentation was calibrated with sediment from the site, and the results from the experiment presented.

    Beschreibung: Hydrograhic (CTD) and acoustic Doppler current profiler (ADCP) observations were made on the North Brazil shelf adjacent to the mouth of the Amazon River during R/V Iselin cruise I9113 November 5-25, 1991 as part of A Multidisciplinary Amazon Shelf SEDiment Study (AMASSEDS). These observations were obtained during a large-scale survey on Leg 3 in support of geological and geochemical sampling, and during a frontal zone survey on Leg 4 consisting of 14 and 26 hourly CTD casts at anchored stations. The maximum sampling depth at each station was within two meters of the bottom. The primary objectives of the AMASSEDS hydrographic meaurement program were (a) to observe and characterize the temperature, salinity, density, oxygen, fluorescence and light transmission fields and their spatial variabilty on the north Brazilian shelf directly influenced by the Amazon River discharge, (b) to resolve the seaward extent and vertical structure of the surface plume of low salinity Amazon River water during different stages of river discharge, (c) to describe the spatial structure of the turbidity and associated suspended sediment distributions across the shelf, (d) to chacterize the properties of the Amazon shelf water beneath the surface plume and their seasonal variabilty, and (e) to describe the landward penetration of the North Brazil Current with respect to water properties and shelf currents. This report represents a summary in graphic and tabular form of the hydrograhic observations made during the fourth AMASSEDS cruise (I9113) on the R/V Iselin.

    Beschreibung: A trans-Indian Ocean hydrographic section employing CTD/O2 profilers was conducted between Africa and Australia during austral spring 1987. The cruise track ranged between 29°S and 34°S; the average latitude of the crossing was 32°S. The purpose of the cruise was to explore various aspects of the South Indian Ocean including the characteristics of the core water masses of this ocean, the strength of the subtropical gyre, the structure and transport of deep western-boundary currents, and the net meridional heat flux. A total of 109 CTD/O2 profiles with associated rosette water sample measurements and 347 XBT profiles were collected, supplemented by underway upper ocean velocity, bathymetric and sea surface temperature and salinity data. This report detals the data collection, calibration, and reduction methods, and summarizes the hydrographic observations.

    Beschreibung: Repeated side-scan sonar and multi-frequency bathymetric surveys, accompanied by accurate, high resolution, and repeatable navigation, were conducted in the vicinity of a tidal inlet to define the length and time scales associated with bedforms and channel shoaling in a structured tidal inlet. The study site, St. Marys entrance channel along the Georgia/Florida border (Fig. 1), has a dredged channel approximately 46-52 feet in depth at a datum of mean low water (MLW), bordered by a large ebb tidal delta. The tidal inlet serves Cumberland Sound, Kings Bay, and associated waterways, providing a large discharge of water from the inlet that creates bedforms and channel shoaling, given the abundance of sand-size sediment in the vicinity. The jettied inlet produces flows that are predominantly tidally-driven, whereas farther offshore the driving forces consist predominantly of waves and storm-generated flows. In the channel reaches (Table 1) between these two areas, combined wave/steady flows are present, creating a myriad of scales of bedforms and shoaling patterns, emphasizing the difference in these scales between the three different flow regimes. The results provide an important data base for quantifying shoaling processes and mechanisms in tidal inlet channels.

    Beschreibung: A bottom instrument was deployed on May 5,1993, recovered and redeployed on June 22, 1993 and finally recovered on July 28, 1993 at a 30 meter site in the New York Bight Apex. The instrument measured currents, suspended sediment concentrations, pressure, temperature and conductivity. The data storage was filled in only seven days on the first deployment as in 18 days in the second. The averaging sampling process worked well, producing hourly (first deployment) and half hourly (second deployment) values of all sensors and instrument internal diagnostics to obtain background environmental information. The burst sampling scheme sampled once a day for waves, and identified 6 and 10 second waves present. The event sampling scheme was tested for the first time. During deployment one, high frequency pressure signals were allowed to trigger events, and bad cabling caused excessive events to be recorded, filling the memory prematurely. For deployment two, only the optical sediment sensors were allowed to trigger events, and 146 events were recorded. Many of the events were only seen in one or the other optical sensor and probably associated with fish or floating debris. Other events had unique signatures, one type possibly due to passing ships.

    Beschreibung: A series of laboratory intercalibrations of a CTD system were undertaken between 1986 and 1990 as part of cooperative research program between the United States (US) and People's Republic of China (PRC). A comparison of US and PRC calibration facility standards is carried out using a NBIS/EG&G Marine Instruments Mark IIIb CTD system as a "quasi-transfer standard." When compared with the quoted accuracy of the calibration facilities, pressure was found to be more accurate and temperatue was about as accurate as stated. The conductivity standard differences between facilities are difficult to assess because of the CTD conductivity sensor drift.

    Beschreibung: In studying the processes controlling particle distrbution of fine sediments over the continental shelf, the height, structure and dynamics of the bottom boundary layer must be better understood. The Sediment Transport Events on Shelves and Slopes (STRESS) program provides a comprehensive set of data over the bottom half of the water column at the 90m and the 130m isobaths along the northern California continental shelf during the winters of 1988-89 and 1990-91. This report presents the STRESS salinity, temperature, velocity, wave characteristics and attenuation data. The report describes the processing, provides plots and tables of the data and corresponding statistics for evaluation of the data, and documents the data fies. The combined set of moored and tripod mounted instrument measurements provides integrated, hourly-averaged profiles of the lower half of the water column at the four sites which can be used for analysis and modeling purposes.
