Validation of NSCAT Remotely Sensed Sea Ice Conditions as a Predictor of Environmental Conditions

本研究提出了一种结合季节冰和候鸟行为特征的白令海东部冬春状态生物物理指数。将用1996年10月至1997年5月所有可用的卫星、船舶和地面站数据核实NSCAT（美国宇航局卫星散射计）数据。将在GIS系统中对当日NSCAT图像与AVHRR（先进甚高分辨率辐射计）图像进行数字分析。NSCAT数据将验证AVHRR图像的有效性，并增加冰生长、融化和退缩的细节，或者提供不同的研究数据来源来评估海冰状况。春季海冰边缘动态的详细地图将有助于了解目前由其他机构资助的大陆架渔业招募过程的研究。在秋季和春季迁徙期间评估的水鸟分布将纳入GIS模型。由于这些机会具有时间敏感性，而且方法具有创新性和探索性，因此pi选择在探索性研究小额赠款（SGER）计划的指导下提交有限范围的提案。

This study proposes to develop a biophysical index of the status of the eastern Bering Sea in winter and spring which incorporates characteristics of the seasonal ice and migratory bird behavior. NSCAT (NASA scatterometer from satellite) data will be verified with all available satellite, ship, and land station data for October 1996 to May 1997. Digital analysis of same-day NSCAT images with AVHRR (Advanced Very High Resolution Radiometer) images will be made in a GIS system. The NSCAT data will either verifgy the usefulness of the AVHRR imagery and add to the detail of ice growth, melt and retreat, or provide a different source of research data to evaluate the conditions of sea ice. Detailed maps of the sea ice edge dynamics in spring will assist in studies aimed at understanding fisheries recruitment processes on the shelf currently being funded by other agencies. Waterbird distributions evaluated during a period encompassing fall and spring migration will be incorporated into the GIS models. Because these opportunities are time sensitive and because the approach is innovative and exploratory, the PIs have chosen to submit a proposal of limited scope under the guidelines of the Small Grants for Exploratory Research (SGER) program.
