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.

本研究拟制定东白令海冬季和春季状况的生物物理指数，其中结合了季节性冰和候鸟行为的特征。 NSCAT（NASA 卫星散射仪）数据将使用 1996 年 10 月至 1997 年 5 月期间所有可用的卫星、船舶和陆地站数据进行验证。将在 GIS 系统中对当天的 NSCAT 图像和 AVHRR（高级甚高分辨率辐射计）图像进行数字分析。 NSCAT 数据将验证 AVHRR 图像的有用性并添加冰生长、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的状况。 春季海冰边缘动态的详细地图将有助于旨在了解目前由其他机构资助的大陆架上的渔业补充过程的研究。 在秋季和春季迁徙期间评估的水鸟分布将被纳入 GIS 模型中。 由于这些机会具有时间敏感性，并且方法具有创新性和探索性，PI 选择根据探索性研究小额资助 (SGER) 计划的指导方针提交一份范围有限的提案。
