The National Science Foundation Division of Ocean Sciences awarded $890,902 to the University of Washington under the Geosciences (CFDA 47.050) federal grant program to support collaborative research investigating bubble-mediated gas exchange in the Labrador Sea. The award period is from October 1, 2022 through September 30, 2025. Under this Project Grant, researchers will conduct an observational study during an expedition to the Labrador Sea in fall 2023 to measure bubble-mediated air-sea invasion and evasion rates of various gases, as well as make detailed observations of gas flux drivers including bubbles and turbulent currents in the mixed layer. They will employ approaches such as one-dimensional and three-dimensional budgets, shipboard direct eddy covariance fluxes, and autonomous vehicles. In addition, the researchers will utilize state-of-the-art numerical models to synthesize the observational data and simulate turbulent ocean currents, bubbles, and dissolved gases. The overarching goal is to develop more accurate mathematical formulations for air-sea gas fluxes suitable for strongly convective environments like the Labrador Sea in order to improve understanding and reduce uncertainty in predictions of ocean ventilation impacts from climate change.
