The Defense Advanced Research Projects Agency (DARPA) is seeking insights through a Request for Information (RFI) titled "Advancements in Ocean Modeling and Monitoring" to enhance national security capabilities. The primary objective is to improve ocean circulation models and the characterization of ocean parameters to prevent strategic surprises, particularly by addressing the current limitations in real-time ocean dynamics data, especially in the ocean's interior. This initiative is crucial for developing innovative technologies, high-resolution sensors, and methodologies that can enhance model accuracy and facilitate real-time data collection. Responses to the RFI are due by October 7, 2024, and interested parties can contact the BAA Coordinator at DARPA-SS-24-02@darpa.mil for further information. Participation is open to all qualified sources, including research institutions and private companies.
