Selected zooplankton from three oligotrophic lakes in Oregon were studied to determine whether or not their instantaneous birth rates and densities could be used in lake classification. The species of zooplankton studied in their respective lakes were Daphnia, pulex in Crater Lake, Daphnia longispina in Odell Lake, and Daphnia longispina...
This technical report summarizes the
results of a three year study of the zooplankton
living in the nearshore zone off
Newport, Oregon. The sampling program was
part of the Early Life History (ELH) project
of the Oregon State University Sea Grant Program
and was designed to study the ecology
of...
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...
This report contains the data gathered at Ocean Station "P" in late June and early July of 1971 on the "SUBARCTIC-A" cruise of R/V YAQUINA. The data include: 1) temperature, salinity, and oxygen profiles; 2) estimates of zooplankton displacement volumes at different depths; and 3) estimates of the numerical density...
In 1960 a program of monitoring the zooplankton populations of Yaquina Bay, Oregon, was begun. The frequency of sampling was maintained at close to weekly intervals after 1 January 1963, usually at five stations. Abundances of all the species found in the bay of both meroplankton and holoplankton have been...
