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

同时，南极沿海冰川是无海冰的地方，也是“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，并在那里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，特别是在极夜期间不适宜居住的海洋生态系统的形成和活动期间，阻碍了这些生产性和多样性海洋生态系统的形成和持续的各种模式。为了更详细地了解南极冰盖在潜热型海冰的产生和通过海冰卤水排斥形成致密海底底水而形成的潜热型海冰和通过海冰卤水形成致密海底底水的作用，对南极冰盖的低层大气性质、海-气表面热通量和相应的海洋水文剖面进行了表征，以便能够持续和安全地观测冬季末和夏初Terra Nova湾(南极洲维多利亚陆地)多尼雅水域的轻、强绝热风场和中尺度气旋的相互作用。

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.
