Jens Hollmann,Katharina Danielseral species in the early 1970s may have been due to Tropical Storm Agnes and to decreases in aquatic vegetation; however, the declines in these fish species were not coincident. Measures of overwinter survival of juvenile croaker were correlated with winter severity. Overwinter survival of juvenile

Although entrainment affects Cryptomonas and flagellate-dominated assemblages in the summer there are no detectable effects of power plant operations on cell densities or productiv

Phytoplankton: Relationships Between Phytoplankton, Nutrients, Oxygen Flux and Secondary ProducersNutrient concentrations and elemental ratios suggest occasional nutrient limitation of phytoplankton production in the region, with a limited phosphorus data set suggesting P-limitation in spring. Nitrogen limitation was possible in approximately one-half of the summer and early fall months sampled
