Overview

The Diatom server supports the Institute for Watershed Studies (IWS) by hosting data for research and operations. The IWS focuses on freshwater system research, offering resources for students and faculty, collaborating with various organizations on regional water quality issues. Robin Matthews, emeritus director of IWS, and her husband, Geoff Matthews, previously maintained the archival resources, but the website is now administered by Angela Strecker.
