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...
Grazing rates and density of the crustacean zooplankton were measured
in Findley and Chester Morse Lakes and Lake Sammamish, Washington.
Sample analysis is incomplete at reporting time, thus estimates of
production from examination of life stage biomass changes was not possible.
Maximum density of crustacean zooplankton was about 10/1 in...
Zooplankton grazing rates and life history stage densities for secondary
production estimates were determined in three lakes in the Cedar River
watershed, Washington. Eight copepod species, seven cladoceran and nine
rotifer species were identified in the three lakes. No one species of
cladoceran or copepod occurred in all the lakes,...
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...
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...
