Zooplankton play a pivotal role in linking primary production to higher level consumers in the food webs of marine ecosystems.The distribution of zooplankton is affected by general water conditions,monsoons,currents,and spatial and temporal factors.In the Arctic Ocean,the sea surface is naturally covered with ice.Under ice,water masses interplay to create complex environments that facilitate the transport and distribution of zooplankton,thus altering community structures in geospatial and vertical scales.This study investigated the species and composition of copepod community structures by using geospatial and multiple depth scales,and used multivariate analyses to evaluate the relative of sampling stations and layers.
