Advancing the role and use of remote sensing for understanding the impact of sea ice on air-sea gas exchange in polar oceans

南极洲周围的海洋对全球人为二氧化碳的吸收尤为重要。我们对混合冰区空气-海洋二氧化碳气体传输的理解存在很大的（三因素）不确定性。例如，海冰可以通过抑制海洋膨胀和改变近地表湍流来改变转移。该项目将使用新的成像方法和无人机技术来量化与测量气体通量相一致的海冰范围。收集到的数据将有助于确定海冰对控制空气到海洋的二氧化碳通量的重要性。主要目标：收集南极半岛东部威德尔海海冰空间范围的新型无人机和船舶测量数据，然后确定这种冰的范围、类型和相互作用如何影响空气到海洋的二氧化碳通量。

The oceans around Antarctica are disproportionately important for the global uptake of anthropogenic carbon dioxide (CO2). Large (factor of three) uncertainties exist in our understanding of air-to-sea CO2 gas transfer in mixed ice regions. For example, sea-ice may alter transfer by suppressing ocean swell and modifying near surface turbulence. This project will use novel imaging approaches and drone techniques to quantify sea-ice extent coincident with measured gas fluxes. The data collected will help establish the importance of sea-ice for controlling air-to-sea CO2 fluxes.Main aim:Collect novel drone and ship-based measurements of sea-ice spatial extent in the Weddell Sea, East of the Antarctic Peninsula, and then determine how this ice extent, type and interactions are influencing air-to-sea CO2 fluxes.
