Species Composition and Abundance of Zooplankton in the Nearshore Beaufort Sea in Winter-Spring

Zooplankton samples collected in winter-spring 1978-79 and in spring 1980 from under the sea ice at two sites near Prudhoe Bay, Alaska, were analyzed for species composition and abundance. Sixty-eight categories, including 48 species and 20 other categories where identification was made to genus or...
