Jeffrey Ziegeweid


I joined the USGS California Water Science Center as the Reports Specialist in 2021 after almost 13 years with the USGS Minnesota and Upper Midwest Water Sciences Centers. I enjoy helping others find ways to improve how to effectively communicate science to a wider audience. My science research interests and experiences are diverse and include (1) using chemical and statistical techniques to understand migration patterns, habitat selection, and physiological responses of fish, (2) relating changes in water levels, streamflow, water quality, and climate on aquatic ecosystem function, (3) fate and transport of sediment in the environment, (4) determination and application of streamflow statistics, and (5) use of hydroacoustic equipment in surface-water studies.
