Creator:: Haight, Janet Jones
Abstract:: Cells of an obligately psychrophilic marine bacterium, Vibrio marinus, strain MP-1, were grown at 4 C and 15 C and studied for possible physiological differences. No differences were noted in sugar fermentation or temperature-shift growth studies; in both cases adequate nutrients were available. Some differences were noted in viability retention...

Creator:: Holton, Robert L.
Abstract:: The brine shrimp, Artemia, was used as an experimental organism to study the effects of ⁶⁰Co gamma irradiation on the reproductive performance of an animal population. The total reproductive ability of the brine shrimp was fractionated into various components and the effects of irradiation on each of these components was...

Creator:: Renfro, William Charles
Abstract:: Levels of ⁶⁵Zn in water, sediments, plants, and animals in Alder Slough, a small ecosystem in the Columbia River Estuary, were determined periodically during a one year period. Concentrations of total Zn in organisms were also measured to permit computation of specific activities (μCi⁶⁵Zn/g total Zn). Temporal fluctuations in the...

Creator:: Cutshall, N. H.
Abstract:: Radioactive chromium-51, a waste byproduct from operation of nuclear reactors at Hanford, Washington, has been followed down the Columbia River and into the Pacific Ocean. Chemical factors influencing the partitioning of ⁵¹Cr between solution and sediment have been considered. Chromium-5l, in a hexavalent oxyanion when introduced into the Columbia River,...
