Abstract
Accurate measurement of air-sea CO2 exchange over a broad range of ocean and atmospheric conditions is required for long- and short-term earth system carbon budgets. Many processes that affect CO2 flux across the air-sea interface vary on short temporal and spatial scales (e.g., wind, waves, white-capping). Eddy covariance (EC), a direct measurement of surface-atmosphere flux with high spatial (1-10 km) and temporal (10-60 min) resolution, is an important tool for developing process-level understanding of air-sea exchange and improving models. We report on a project that builds on previous NSF investments to develop a low-power, buoy-based air-sea EC CO2 flux measurement system that can be readily integratedonto mobile platforms and deployed in harsh marine environments. The work involves ongoing collaboration between UNH, SUNY/Albany, WHOI, and Campbell Scientific.

Douglas Vandemark is a research professor in the Ocean Process Analysis Laboratory at UNH. His research interests lie in air-sea interactions with a focus on ocean remote sensing of wind waves and the air-sea exchange of momentum, heat, and mass including greenhouse gases. Funded projects often involve the use of microwave remote sensing systems including altimetry, scatterometry, radiometry, and synthetic aperture radar as well as in situ measurement techniques and instrumentation - applied at regional and global scales. His group is also developing observation platforms and sensors to support improved measurements. Recent research includes participation as a He is the principal investigator on several NASA science teams including those for SWOT, Ocean Surface Topography, Ocean Vector Wind, Ocean Sea Surface Salinity, and GLIMR.
