Field, Lab and Modelling Study of Microscale Copepod Distributions

Abstract

To understand the in situ microscale (cm's) and fine-scale (m's) relationships between copepods and their phytoplanktonic food source, and to explore how copepods in the upper ocean are regulated by, and forage within their phytoplanktonic food. The objectives of the research are to understand how copepod ingestion and swimming behavior change over short (<2 hour) time scales, under a suite of different food and acclimation conditions. New techniques to determine the gut content of individual copepods are being developed to relate individual behavior to individual feeding success. Models will be used to test hypotheses of copepod foraging strategies in patchy environments. The models will be parameterized with laboratory data, and forced with data gathered from the LUMIS and FishTV deployments (Jaffe and Franks, parent grant).
