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吸收人为二氧化碳（CO2）的重要性不成比例。大（三个因素）的不确定性存在于我们的理解空气到海洋的CO2气体传输在混合冰区。例如，海冰可以通过抑制海洋涌浪和改变近表面湍流来改变传输。该项目将使用新的成像方法和无人机技术来量化海冰范围与测量的气体通量。收集的数据将有助于建立海冰的重要性，为控制空气到海洋的CO2 flux.Main aim：收集新的无人机和船舶为基础的测量海冰的空间范围在威德尔海，东南极半岛，然后确定这种冰的范围，类型和相互作用是如何影响空气到海洋的CO2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.
