Has been Assistant Professor of Research at Drexel University, and Supervisor of the Neutron Activation Analysis Facility in Pullman, Washington, and Chemex Labs, Ltd. In North Vancouver, British Columbia, Canada. Dr. Blomquist is currently assisting with the MATERHORN project with Professor Fernando at Notre Dame. ABSTRACT Exchange of heat, gases and particles across the air-sea interface is an important process in global climate dynamics and geochemical cycles. Early theoretical and experimental efforts led to development of physically based parameterizations of heat and trace gas exchange (e.g. the NOAA COARE model). Theoretical advances have outstripped observations, however, especially in the high-wind speed regime, where effects of surface gravity wave properties, bubble plumes and spume production are important. The High Wind Gas Exchange program (HiWinGS) was conceived to address some of these observational deficiencies. In October/November 2013 a measurement campaign was conducted in the Labrador Sea. We will outline the various HiWinGS observations, present some initial results and discuss ongoing analysis.
