<P> While plankton are most abundant in surface waters , they live throughout the water column . At depths where no primary production occurs , zooplankton and bacterioplankton instead consume organic material sinking from more productive surface waters above . This flux of sinking material , so - called marine snow , can be especially high following the termination of spring blooms . </P>
