Collaborative Research: Ocean-Ice-Atmosphere Interactions in the Terra Nova Bay Polynya, Antarctica

同时，南极沿海的多角体也是无海冰地区和“海冰工厂”。它们是开放的水面位置，在那里发生水团转化和致密化，并建立与深海环流的大气交换。由于相对缺乏现场气象和物理海洋学观测，特别是在极地夜晚这些生态系统形成和活动的恶劣条件下，关于这些多产和多样的海洋生态系统的形成和持续的各种模型受到阻碍。对南极冰穴的低层大气特性、海气表面热通量和相应的海洋水文剖面进行表征，特别是在强风事件期间，是为了更详细地了解冰穴在产生潜热型海冰和通过海冰盐水排斥形成冰穴方面的作用，这项工作的一项关键技术创新仍然是使用装有仪器的无人驾驶飞机系统，以便能够持续和安全地观察轻型和强风场的相互作用，和中尺度气旋在特拉诺瓦湾（维多利亚土地，南极洲）冰间沃茨在冬末夏初的时间框架。

Antarctic coastal polynas are, at the same time, sea-ice free sites and 'sea-ice factories'. They are open water surface locations where water mass transformation and densification occurs, and where atmospheric exchanges with the deep ocean circulation are established. Various models of the formation and persistence of these productive and diverse ocean ecosystems are hampered by the relative lack of in situ meteorological and physical oceanographic observations, especially during the inhospitable conditions of their formation and activity during the polar night. Characterization of the lower atmosphere properties, air-sea surface heat fluxes and corresponding ocean hydrographic profiles of Antarctic polynyas, especially during strong wind events, is sought for a more detailed understanding of the role of polynyas in the production of latent-heat type sea ice and the formation, through sea ice brine rejection, of dense ocean bottom watersA key technological innovation in this work continues to be the use of instrumented unmanned aircraft systems (UAS), to enable the persistent and safe observation of the interaction of light and strong katabatic wind fields, and mesocale cyclones in the Terra Nova Bay (Victoria Land, Antarctica) polynya waters during late winter and early summer time frames.
