Topography-Induced Variation in Benthic Boundary Layer Particle Dynamics and Fauna

Abstract

The long term objective of this research was to identify the physical and biological mechanisms that regulate the structure of infaunal communities on Pacific seamounts. Of particular interest were the interrelationships of hydrodynamic regime, organic input, sediment properties, oxygen availability, and their influence on infaunal communities inhabiting seamounts. Studies involved comparisons of sediments and infauna in naturally-varying and experimentally-manipulated settings on Volcano 7 off Mexico and the summit plain of Fieberling Guyot. Seamounts serve as excellent models for evaluating the response of benthic assemblages to physical processes in the open ocean.
