Abstract
AbstractThe dry mass of zooplankton and backscatter from an acoustic Doppler current profiler (ADCP) used in Sagami Bay, Japan, from 9 to 13 April 2005 were well correlated (correlation coefficient = 0.72, root mean square dry weight = 2.5 mg m−3). The horizontal current field and zooplankton distribution were estimated from shipboard ADCP data. Although sea surface temperature and chlorophyll a concentration observed by satellite were consistent with the current field, a counterclockwise circulation associated with the Kuroshio meander, zooplankton were mainly distributed downstream of the phytoplankton population by horizontal current advection.
