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 patterns. A few taxa could not be so grouped.
Examination of hydrographic features reveals correlations between
animal distributions and strong hydrographic gradients.
It is concluded that: 1. In boreal oceanic waters, few
animals perform diurnal migrations, 2. Depth ranges for most
zooplankton are on the order of hundreds of meters, and 3. Hydrographic
features may influence the vertical distributions and
migrations of zooplankton. / Graduation date: 1974
