The proposed research would test the feasibility of a long term observatory in the Bering Strait region of Alaska. The key facility would be a pumping station located on Little Diomede Island in the center of the Strait. Seawater from depth would be pumped to a laboratory on shore in which the waters' physical, biological, and chemical composition would be determined by automated instrumentation and from samples collected manually. These results would be compared to and used in relation to long-term data on water flows through the Strait, and thus could potentially supply important information about inputs of biota and seawaters into the Arctic. Additional data would be collected concerning the abundance of macrobenthic animals found in richer sediments both north and south of the Strait. Marine mammals collected by the local village would be examined and catalogued as part of the long-term records for the site.

这项拟议的研究将测试在阿拉斯加白令海峡地区建立长期天文台的可行性。关键设施将是位于海峡中心小迪奥米德岛的一个泵站。来自深处的海水将被泵送到岸上的一个实验室，在那里，水域的物理、生物和化学成分将通过自动化仪器和手动采集的样本进行测定。这些结果将与流经海峡的水流的长期数据进行比较和使用，从而可能提供有关生物群和海水进入北极的重要信息。将收集更多关于在海峡北部和南部较丰富的沉积物中发现的大型底栖动物丰度的数据。当地村庄收集的海洋哺乳动物将被检查和编目，作为该地点长期记录的一部分。
