As a component of the Multidisciplinary drifting Observatory for the Study of Arctic Climate project (MOSAiC), a multi-institutional collaboration led by CU/CIRES & NOAA/PSL conducted direct air-sea flux measurements of climate-active trace gases carbon dioxide, methane, dimethyl sulfide, and ozone. The primary goal of this project is a synthesis of direct gas transfer measurements with biogeochemical and physical observations of the atmosphere, ocean, and sea ice to improve the understanding of processes controlling trace gas exchange in the Central Arctic. This talk will provide an overview of activities during the field measurement phase and a discussion of the issues related to physical gas transfer models in a sea ice environment.
