The goal of this project is to identify the organisms and conditions that result in odors and off-flavors in the Seattle water supply. To date, this project has isolated numerous algae and Cyanobacteria from Seattle Reservoirs, selected odor producers, and cultured (a) Chlorophyta and (b) Cyanobacteria under a variety of conditions that might contribute to odor production, including anaerobic night time conditions.

As part of a two-year fellowship program, I studied early feeding behavior of zebrafish (selected for research on International Space Station) and the development of Closed Ecological Systems (marine, freshwater, and synthetic.)

The purpose of this project is to evaluate the growth of the alga Euglena in a cell culture unit prototype being developed for the International Space Station. It provides an opportunity to study community metabolism and gravitational effects. The preliminary testing will be performed at University of Washington, and the final testing will be performed at NASA Ames Research Center, Mountain View, California.

The Standardized Aquatic Microcosm (SAM) was developed to provide ecosystem-level testing of chemicals such as might be recommended by the U.S. Environmental Protection Agency and U.S. Food & Drug Administration. The protocol was successfully re-balloted and is published as Standard Practice E-1366 (American Society for Testing Material [ASTM]). Major activity this year has been the translation of the experimental data tapes from the Cyber computer to a modern format on Iomega® Zip Drives.

These investigations have involved undergraduate student research and systems I developed during my ASEE-NASA Summer Faculty Fellowship. I have been exploring community metabolism of microcosms.
