The Sewee shell ring is part of a complex water gathering system built in a Carolina bay designated as Oak Bay. The seaward boundary of the shell ring, the sand rim of Oak Bay, and a surface exposed aquiclude/aquitard stratum are concordant. A Slough

Natural water gathering in two newly discovered Carolina bays, designated as Oak Bay and Pine Bay was studied. These bays and the Sewee shell ring, a planned water gathering system built by man approximately 4,100 yr BP, provided a supply of freshwat

The rapid decrease of several stocks of Pacific herring, Clupea pallasi, in Puget Sound, Washington, has led to concerns about the effects of industrial and nonpoint source contamination on the embryo and larval stages of this and related forage fish

Topsmelt (Atherinops affinis) were spawned repeatedly in the laboratory from May to July 1989. A periodic “temperature spike” from the holding temperature of approximately 18 up to approximately 20.5°C, introduced at 7- to 9-d intervals, resulte

Flow-through acute and early-life-stage (ELS) toxicity tests were conducted with topsmelt (Atherinops affinis), a Pacific coast saltwater fish, and fenvalerate, a synthetic pyrethroid insecticide. The 96-h LC50 for juvenile fish was 0.66 μg/L. In th

Larval topsmelt (Atherinops affinis) and inland silversides (Menidia beryllina) were exposed in 96-h static acute toxicity tests to 11 chemicals to determine the relative sensitivity of the two atherinid species. High to low LC50 ratios for endosulfa
