The Department of Defense, specifically the Navy, is seeking proposals for the Small Business Innovation Research (SBIR) program focused on developing low-cost floats for observing interior ocean flows. The objective is to design and demonstrate an expendable ocean float system that can be deployed in large numbers to reconstruct flow trajectories in the ocean, particularly in challenging environments like the Arctic where traditional methods are hindered by sea ice. This initiative aims to enhance oceanographic research and improve numerical ocean models through the assimilation of data collected by the proposed system. The solicitation is currently closed, with the next phase opening on May 15, 2024, and applications due by June 12, 2024. For more information, interested parties can visit the official SBIR website at https://www.dodsbirsttr.mil/topics-app/.
