Zooplankton Aggregation Near Sills

Abstract

The long-term goal is improved knowledge of the physical and biological mechanisms and interactions responsible for forming and maintaining aggregations of biological sound-scatterers in the ocean. Dense aggregations of plankton and fish often occur in localized regions where ocean currents interact with steeply sloping seabed. These sites are ecologically important 'hot spots' for prey-predator trophic interactions, and are also zones of very strong acoustic backscatter. Our project examines the biological and physical mechanisms responsible for forming, maintaining and dispersing zooplankton aggregations near the sill of Knight Inlet, a large fjord in British Columbia (sill at 50 41'N 126 00'W).
