The U.S. Geological Survey (USGS) is offering a cooperative agreement opportunity for partners affiliated with the Californian Cooperative Ecosystem Studies Unit (CESU) to conduct research on evapotranspiration (ET) models across various wetland sites in the United States. The objective is to utilize data from the Open Evapotranspiration platform, alongside ground data, to enhance the understanding of biophysical processes and improve the accuracy of hydrologic ecosystem characterizations. This funding is crucial for advancing scientific research and technical assistance related to wetlands, with an award ceiling of $285,000 and no matching requirement. Interested applicants must submit their proposals electronically by 5:00 p.m. ET on June 21, 2024, and can reach out to Faith Graves at fgraves@usgs.gov for further information.
