Optical and Acoustic Analysis of Arabian Sea Epizooplankton
Abstract
LONG-TERM GOALS. Our research has been and will be directed at understanding the coupled biological and physical mechanisms controlling the fine-scale (1-10m) vertical distributions of epizooplankton, the ecological significance of these distributions and their effect upon other "particles" within the upper water column. This has lead to a focus upon the following set of inter-related questions: a) Do physical gradients influence zooplankton distributions directly or indirectly? b) Is the vertical distribution of zooplankton controlled by density gradients or loci of current shear situated within steep density gradients? c) How strong a physical gradient must exist and how long must it persist to influence the zooplankton distribution? d) How and under what circumstances does the fine-scale distribution of epizooplankton particle-grazers affect the fate of particles within the upper water column? e) To what degree does local turbulence control fine-scale zooplankton distributions and how does this vary with the relative motility of different zooplankton taxa?
