Importance of Thin Plankton Layers in Hawaiian Food Web Interactions: Research Spanning From Physical Circulation to Spinner Dolphins

Abstract

Our goals are (1) to quantify layered aggregations of the phytoplankton, zooplankton, and the nearshore sound-scattering layer around Hawaii, (2) to identify the physical, optical, and acoustical characteristics associated with these aggregations, (3) to assess the horizontal scales of coherence between these various levels of biological aggregations and understand their interactions, (4) to assess the impact of these layers on optical and acoustical measurements in the nearshore environment, (5) to determine the effects of layered aggregations on spinner dolphins. Our long-term goal is to develop the capability to predict the occurrence and consequences of layer structure and biological aggregations in coastal waters.
