Collaborative Research: Atmosphere-Ocean-Ice Interaction in a Coastal Polynya

摘要南极冰川是通常存在于大陆海冰中的无冰地带。需要对南极波尼亚的低层大气特性、海气表面热通量和相应的海洋深度剖面进行表征，特别是在大风事件期间，以便更详细地了解波尼亚在产生潜热型海冰以及通过排出盐水形成密集海底水域方面的作用。更广泛的影响：将采用一项关键技术创新，即使用仪表式无人驾驶飞机系统，以便能够持续和安全地观测冬末夏初期间轻、强katabatic风场与Terra Nova Bay(南极洲维多利亚陆地)Polynya水域的相互作用。到目前为止，UAS观测平台在非洲大陆的使用一直不多，但在测量和观测模式中展示其多功能性和有效性是一个值得欢迎的发展。科罗拉多大学和LDEO(哥伦比亚)研究人员使用UAS平台的项目都是高风险的，对于许多南极科学应用日益需要的系统数据测量任务来说，可能具有变革性。

Abstract Antarctic polynyas are the ice free zones often persisting in continental sea ice. Characterization of the lower atmosphere properties, air-sea surface heat fluxes and corresponding ocean depth profiles of Antarctic polynyas, especially during strong wind events, is needed for a more detailed understanding of the role of polynya in the production of latent-heat type sea ice and the formation, through brine rejection, of dense ocean bottom waters. Broader impacts: A key technological innovation, the use of instrumented uninhabited aircraft systems (UAS), will be employed to enable the persistent and safe observation of the interaction of light and strong katabatic wind fields with the Terra Nova Bay (Victoria Land, Antarctica) polynya waters during late winter and early summer time frames. The use of UAS observational platforms on the continent to date has to date been modest, but demonstration of their versatility and effectiveness in surveying and observing mode is a welcome development. The projects use of UAS platforms by University of Colorado and LDEO (Columbia) researchers is both high risk, and potentially transformative for the systematic data measurement tasks that many Antarctic science applications increasingly require.
