Role of Protozoan Grazing in the Fate and Transport of Particle Reactive Trace Elements in the Marine Environment.

Abstract

The goal was to determine the importance of protozoan grazing on the fate and transport of particle reactive elements, by studying the chemical transformations of particulate metals when ingested by protozoan grazers. These goals were established based on previous work which had shown the importance of protozoans in marine ecosystems, and their role in ingesting particles in the 0.2 to 2 micron size class range - an important reservoir of particulate metals and contaminants in seawater. We anticipated that the grazing process would create a chemical microenvironment where many processes would be accelerated relative to bulk seawater. This project was an AASERT Award and was the dissertation research of Katherine A. Barbeau, MIT/WHOI Joint Program.
