The U.S. Geological Survey (USGS) is offering a funding opportunity to a CESU partner for state-of-the-art research on gas and fluid composition analysis from deep-sea environments in the Aleutian Island Arc, U.S. Exclusive Economic Zone (EEZ). The goal is to characterize the fluid and gas environment to inform our understanding of active submarine volcanism. • The USGS conducts ecological studies to understand deep-sea environments and the associated natural resources. • Research conducted by USGS scientists, and their research partners improves understanding of deep-sea environments, their spatial distribution, and sensitivity to disturbance. • The USGS is seeking research and technical assistance relevant to characterizing fluid and gas composition in deep-sea environments within the Aleutian Island Arc. • Eligible recipients must be a participating partner of the Pacific Northwest CESU Program.
