Georges Bank

Tilefish, Lopholatilus chamaeleonticeps] 1981-1982 New Jersey vs. Georges Bank Total PCBs ... 

The most prominent PCB congeners at 280 to 323 pg/kg DW in the tilefish (Lopholatilus chamaeleonticeps) from Georges Bank in 1981 to 1992 were PCBs 138 and 153 in gonad and liver. At 69 to 82 pg/kg DW, the most prominent PCB congeners in the tilefish from New Jersey during this same period were PCBs 138 and 153 in liver (Steimle etal. 1990). Total PCB concentrations in marine coastal fishes were dominated by the hexachlorobiphenyls (Knickmeyer and Steinhart 1989), but trout from isolated mountain lakes had tri-, tetra-, and pentachlorobiphenyls as the major components of total PCBs (Sanchez et al. 1993).

Also shown are deliberate tracer data from the southern North Sea ( ), the Florida Shelf (A), and the Georges Bank ( ) (Nightingale et al., 2000a) (reproduced by permission of American Geophysical Union from Geophys. Res. Lett., 2000, 27, 2117-2120).

Top the equation R = 1.92 ETS — 0.99, where R is the oxygen-consumption rate, describes the samples taken from the Georges Bank-Gulf of Maine cruise on the R.V. Eastward in July 1980. Bottom the equation R = 1.29 ETS + 4.71 describes the ETS dependence of oxygen consumption of the bacterium, P. perfectomarinus. The differences in the equations may reflect the differences of the analysis of bacterial and phytoplankton ETS. In bacteria the ETS is housed in the cell mall, so crude homogenates must be used. In phytoplankton the ETS is housed in the mitochondria thus, partially purified homogenates free of cell walls and nuclei are used. (Reproduced with permission from Ref. 67 and 75.)... 

Fish production varies even on different parts of a single bank. Clyde Taylor, of the U. S. Fish and Wildlife Service (1955, personal communication), estimates roughly the total population of bottom fishes in different areas of Georges Bank, Gulf of Maine, in tons per square mile, as follows 18.0 (area G), 10.5 (area H), 27.9 (area J) 9.9 (area M) and 4.8 (area N).

Figure 14. Change in SFe/ He ratio over time during the gas transfer experiment on Georges Bank. From Wanninkhof el al. (1993).

Wanninkhof parameterization, being tuned to global exchange rate, is most affected by the open ocean and the Liss-Merlivat formulation, originally calibrated from the result of lake experiments, the most affected by organics. The two data sets lie in between these. Georges Bank might be expected to be less coastally influenced than the North Sea, and the trend in the results is consistent with that expectation.
