The National Science Foundation awarded The Johns Hopkins University a $466,423 Project Grant under the Geosciences program (CFDA 47.050) for work spanning March 15, 2023 through February 28, 2026. The university will utilize ocean models to understand how melting Arctic ice and precipitation influence ocean currents in the North Atlantic. Researchers will track Arctic waters using novel approaches including artificial intelligence to determine the fate of Arctic water and sources of unusually fresh water in the subpolar North Atlantic. The study seeks to observe, understand, and anticipate the export and impacts of Arctic-derived fresh water on the region to identify the timing and characteristics of anthropogenic freshwater signals. It will apply new tools to model outputs to study freshwater anomalies and their sources. Broader impacts include increased understanding of Arctic freshening and its influence on overturning ocean currents affecting global climate.
