Ecological effects of nuclear steam electric station operations on estuarine systems. Volume I. The purpose of this study is several-fold: to determine present base levels of gamma-emitting radioactive species in sediments that may be affected by the operation of the Calvert Cliffs Nuclear Power Plant; to measure the distributions of these radionuclides as sorbed and mineralic (K, U, and Th) species among various sediment materials (i.e., quartz sand, clay, organic matter, minor mineral components); to study variations in concentrations with time (including the effect of resuspension or deposition of sediment by storm activity) and with other measurable parameters of the Bay, such as pH, temperature, salinity; and to investigate the uptake of existing radionuclides by vegetative and animal species in the Bay. Preliminary studies utilized sediment samples obtained from the surface (to about 10 cm) of the Bay floor on a quarterly basis by anchor dredge, under the direction of personnel from the Hallowing Point Field Station. The locations of these sampling sites are described. Data are included from samples obtained on (auth)
