Automated Analysis of Zooplankton Size and Taxonomic Composition

Abstract

The goal of this project is to develop methods for automated analysis of zooplankton size and taxonomic composition using images from the Video Plankton Recorder (VPR). The goal is to sort plankton to species or genus level and measure body size in real time at sea. The VPR provides sharply focussed video images of plankton and seston in the size range 100 microns to 5 cm and has an on-board CTD, fluorometer, flowmeter, and transmissometer. Currently the VPR is towed at 0.5-5.0 m/s and has been deployed in shelf and oceanic waters, including extensive survey work on Georges Bank. The VPR has also been deployed on the ROV JASON for individual particle tracking, and a moored profiling system is under development, which will include on-board image processing and satellite telemetry of processed data.
