Sediment transport on the northern Oregon continental shelf

Creator:: Harlett, John Charles
Abstract:: The distribution of surface sediments on the northern Oregon continental shell is characterized by a nearshore sandy facies and an outer shelf muddy facies, separated by a mid-shelf zone of mixed sand and mud. Currents which have been measured at 130 centimeters above the bottom indicate that the distribution of...

Vertical distribution patterns in a subarctic Pacific zooplankton community

Creator:: Marlowe, Christopher J.
Abstract:: A study has been made of the vertical distributions and migrations of a large number of zooplankton species at Weather Station "P" in the Subarctic Pacific. Simultaneously towed horizontal opening-closing nets were used for the study. The distributions and migrations of 104 taxa have been subjectively grouped into seven basic...

Plankton and nutrient ecology of the Columbia River estuary

Creator:: Haertel, Lois Steben
Abstract:: Monthly samples of nutrients, phytoplankton and zooplankton were taken in the Columbia River estuary over a period of 16 months in order to determine distribution with season and salinity, and interrelationships between plankton and nutrients. Nitrate and phosphate levels in the river water entering the estuary are high in the...

Chromium-51 in the Columbia River and adjacent Pacific Ocean

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,...

Water tracing with soluble metal chelates and neutron activation analysis : a laboratory and field study

Creator:: Hanson, Peter James
Abstract:: Research on the application of soluble, metal chelates for water tracing using thermal neutron activation analysis for tracer determination has led to the development of several tracers with promising solution stabilities (conservative behavior) and determination sensitivities. The solution stabilities of the ethylenediamine tetraacetic acid (EDTA) and the diethylenetriamine pentaacetic acid...
