Chris Osburn

Bio

Chris uses geospatial analytics to investigate how land use and extreme weather events affect the biogeochemistry of coastal waters. He develops algorithms and modeling approaches to relate the chemistry of natural waters to their optical properties to study fluxes and cycling of carbon and nutrients between the land and ocean through rivers and estuaries. Other interests include investigating the influence of land use and global change on carbon cycles in lakes.
