    Description: High salinity and arsenic (As) concentrations in groundwater are widespread problems in the tidal deltaplain of southwest Bangladesh. To identify the sources of dissolved salts and As, 81 groundwater samples from the regional shallow Holocene aquifer were collected from tubewells during the dry (May) and wet (October) seasons in 2012-2013 and analyzed. Thirteen drill cores were logged and 27 radiocarbon ages measured on wood fragments to characterize subsurface stratigraphy.

Geochemical Transactions, 18, 1-23, https://doi.org/10.1186/s12932-017-0042-3
    Publication Date: 2024-01-27
    Description: To identify the causes of salinization and arsenic contamination of surface water on an embanked island (i.e., polder) in the tidal delta plain of SW Bangladesh we collected and analyzed water samples in the dry (May) and wet (October) seasons in 2012-2013. Samples were collected from rice paddies (wet season), saltwater ponds used for brine shrimp aquaculture (dry season), freshwater ponds and tidal channels (both wet and dry season), and rainwater collectors. Continuous measurements of salinity from March 2012 to February 2013 show that tidal channel water increases from ~0.15 ppt in the wet season up to ~20 ppt in the dry season. On the polder, surface water exceeds the World Health Organization drinking water guideline of 10 µg As/L in 78% of shrimp ponds and 27% of rice paddies, raising concerns that produced shrimp and rice could have unsafe levels of As. Drinking water sources also often have unsafe As levels, with 83% of tubewell and 43% of freshwater pond samples having 〉10 µg As/L. Water compositions and field observations are consistent with shrimp pond water being sourced from tidal channels during the dry season, rather than the locally saline groundwater from tubewells. Irrigation water for rice paddies is also obtained from the tidal channels, but during the wet season when surface waters are fresh. Salts become concentrated in irrigation water through evaporation, with average salinity increasing from 0.43 ppt in the tidal channel source to 0.91 ppt in the rice paddies. Our observations suggest that the practice of seasonally alternating rice and shrimp farming in a field has a negligible effect on rice paddy water salinity. Also, shrimp ponds do not significantly affect the salinity of adjacent surface water bodies or subjacent groundwater because impermeable shallow surface deposits of silt and clay mostly isolate surface water bodies from each other and from the shallow groundwater aquifer. Bivariate plots of conservative element concentrations show that all surface water types lie on mixing lines between dry season tidal channel water and rainwater, i.e., all are related by varying degrees of salinization. High As concentrations in dry season tidal channel water and shrimp ponds likely result from groundwater exfiltration and upstream irrigation in the dry season. Arsenic is transferred from tidal channels to rice paddies through irrigation. Including groundwater samples from the same area (Ayers et al. in Geochem Trans 17:1-22, 2016, doi:10.1186/s12932-016-0036-6), principal components analysis and correlation analysis reveal that salinization explains most variation in surface water compositions, whereas progressive reduction of buried surface water by dissolved organic carbon is responsible for the nonconservative behavior of S, Fe, and As and changes in Eh and alkalinity of groundwater.

    Description: The New York Bight consists of the waters lying between Cape May, New Jersey, and Montauk Point, Long Island. A portion of the general southwesterly current known as the Coastal Drift lies in the seaward part of the Bight. Inshore from the Coastal Drift is an area of complex hydrography where the combined outflows of the Hudson River and other rivers enter the sea. In the region where the New Jersey and Long Island coastlines converge, an area 25 nautical miles on each side has been studied at all seasons of the year. This area extends from Sandy Hook southward to a point off Seaside Heights, eastward to 73°15' W longitude, north to the Long Island shore, and westward to Rockaway Inlet. The depth of water in the area averages about 90 feet, except in the innermost part of the Hudson Canyon which runs roughly northwest-southeast across most of the survey area. In the Canyon, depths in excess of 240. feet are found within the limits of the area studied. The hydrographic conditions in the area are in essence similar to those off the mouths of other large rivers. The combined flows of the Hudson and other rivers entering the surveyed area discharge enough fresh water annually to replace about one-half of the total volume of water under the 600 square miles of sea surface extensively surveyed. The salinity within the area is nearly as high as that of adjacent coastal water, however, and the actual quantity of river water within the area at any time rarely exceeds one percent of the total volume of water. Quantitative evaluation of these factors has led to the conclusion that there is an active circulation within the area which rapidly disperses the introduced river effluent. Many surveys of coastal and estuarine waters have been made. Outstanding among these are the survey of the River Tees, (1931, 1935), of the Tamar Estuary, (Hartley and Spooner, 1938; Milne, 1938), and of Alberni Inlet, (Tully, 1949). The general principles of estuarine circulations may be summarized as follows: In order to remove the added river water there must be a non-tidal drift of mixed water in a net seaward direction. When river flow remains constant, a steady state distribution of fresh and salt water throughout the estuary is attained, and at such times the net transport of river water seaward through any complete cross section of the estuary exactly equals the contribution of fresh water from the river during the same interval of time. As the mixture containing the river water moves seaward it gets progressively more saline, as additional sea water is entrained. In order to provide this sea water there must be a counter drift having a net flow in a landward direction. Superimposed on these necessary parts of the circulation are tidal and wind currents. The velocities of the tidal currents are commonly much greater than the velocity of the non-tidal drift, making the latter difficult to measure directly. It can be inferred, however, from the distribution of river water, as derived from the salinity distribution. Using the river water in this way we have evaluated the exchanges of the waters within the New York Bight. Tully (1949) has analyzed the circulation in Alberni Inlet by similar methods. Tidal current measurements made by the Coast and Geodetic Survey at various locations in the northwestern corner of the surveyed area are summarized by Marmer (1935). At Scotland Lightship, which is the location of the stations at the western end of Section A in Figure 1, the total excursion which results from the flood or ebb tidal currents is less than two miles. The currents at Ambrose Lightship, about five miles to the eastward, produce displacements only about half as great. The tidal displacements throughout the rest of the area are presumed to be less than these. The pattern of distribution of properties will be displaced, therefore, a distance less than ±1 mile at various stages of the tide. This distance is small in comparison to the size of the area surveyed, especially when considering the fact that distances between stations ranged from 5 to 8 miles. It was unnecessary, therefore, to attempt to take comparable stations at similar stages of the tide. Other considerations, beside its interesting hydrography, have contributed to the choice of this area for study. Because it is adjacent to centers of dense population and heavy industrial concentration, the New York Bight serves the conflicting purposes of waste disposal and recreation. Sewer effluents and industrial wastes enter the area by way of the rivers. Sewage sludges are barged out and dumped within the region studied. During the period covered by our surveys, The National Lead Company commenced operations to barge and discharge at sea the waste from its titanium plant at Sayreville, New Jersey. Since iron was a major constituent of this waste, analyses for iron in the water were made at each station, and the results have been valuable in checking the rate of the circulation which was computed from the distribution of river effluent. The New York Bight is also used extensively for recreational purposes. Because the area is readily and cheaply accessible by public transportation it must serve the recreational demands of a large part of the population of metropolitan New York. Sport fishing, bathing and boating are the principal recreational activities. Small but valuable commercial fisheries for shellfish and fin-fish also exist. The purpose of this study was to investigate the hydrographic processes in the New York Bight since they have an important bearing on the general problems of coastal oceanography and a knowledge of them should lead to a more successful evaluation and utilization of the area for the diverse purposes it must serve.

    Notes: Abstract Experimental and thermodynamic data and the apparent immobility of Ti under metamorphic conditions suggest that rutile is very insoluble in aqueous fluids at upper crustal conditions. New solubility measurements at 1.0–2.93 GPa and 800–1200°C show, however, that under certain pressure and temperature conditions rutile is quite soluble in H2O. Solubilities were estimated from the measured weight loss of a single crystal equilibrated with a known mass of fluid in a piston cylinder apparatus. Measured solubilities in H2O range from 0.15 wt% (wt loss crystal/wt fluid) at 2.93 GPa and 1000°C to 1.9% at 1.0 GPa and 1100°C. Solubility increases with increasing temperature and with decreasing pressure in a manner given by the following fit to the experimental data: $$\log _{10} m_{Ti} = - 7049/T - (0.589* P)/T + 5.14$$ wherem Ti is the molality of Ti in the fluid,T is in degress Kelvin andP is in MPa. The effect of fluid composition on rutile solubility was also examined at 1.0 GPa and 1000°C for H2O-CO2, 1m NaCl, and 1m HF fluids. Kesults suggest that solubility depends on the mole fraction of H2O in the fluid but is independent of ionic strength and fluid pH. This behavior implies that Ti dissolves as the neutrally-charged hydrolysis product Ti(OH)4. The free energy of this species was calculated for each set of experimental conditions. TheP-T dependence of rutile solubility suggests that aqueous fluids derived from subducted oceanic lithosphere would dissolve rutile or other Ti-rich minerals from the deepest portion of the mantle wedge and precipitate them at higher levels. Subsequent melting of the base of the mantle wedge would form HFSE-depleted IAB.
