边缘冰区和北冰洋国家方案研究了控制波弗特海快速变化的季节性冰区演变的过程。在冰上和水柱内运行的自主平台收集了整个大气-冰-海洋系统的测量结果，并提供了在海冰春季退缩和秋季推进期间持续采样的持久性。自主平台还允许业务模式减少外地方案的后勤需求。观测表明，热力学，特别是冰-反照率反馈的辐射平衡支配着海冰的季节循环，而表面波的作用仅限于特定事件。从冬季到秋季的连续采样也揭示了冬季冰情和断裂对夏季浮冰粒度分布的影响。这些项目展示了有效地利用集成的自主平台系统进行持续、多尺度的北极观测。自主系统网络非常适合捕捉北极系统固有的巨大变异性。
The Marginal Ice Zone and Arctic Sea State programs examined the processes that govern evolution of the rapidly changing seasonal ice zone in the Beaufort Sea. Autonomous platforms operating from the ice and within the water column collected measurements across the atmosphere-ice-ocean system and provided the persistence to sample continuously through the springtime retreat and autumn advance of sea ice. Autonomous platforms also allowed operational modalities that reduced the field programs' logistical requirements. Observations indicate that thermodynamics, especially the radiative balances of the ice-albedo feedback, govern the seasonal cycle of sea ice, with the role of surface waves confined to specific events. Continuous sampling from winter into autumn also reveals the imprint of winter ice conditions and fracturing on summertime floe size distribution. These programs demonstrate effective use of integrated systems of autonomous platforms for persistent, multiscale Arctic observing. Networks of autonomous systems are well suited to capturing the vast scales of variability inherent in the Arctic system.
