Geophysical Study of Chukchi Borderland and Lomonosov and Alpha Ridges

摘要该奖项支持从一艘核潜艇在操作SCICEX-95巡航到北冰洋的地球物理调查。这项调查将产生一份楚科奇边界以及罗蒙诺索夫海岭、马卡罗夫海盆和门捷列夫海岭部分地区的水深和重力综合图。这些地区不在航空地球物理平台的正常工作范围内，西方科学家可以获得的该地区的数据极其稀少。拟议的调查旨在检验目前对该区域主要地理特征的地质结构和构造发展的假设。 无论这些假设是否属实，这些数据都将填补北冰洋海盆地球物理数据覆盖面的一个明显空白。 因此，所收集的数据将对确定该区域的地质和构造结构很有价值，反过来也将有助于评价该区域发展的构造模型。

Abstract This award supports a geophysical survey from a nuclear submarine during operation SCICEX-95 cruise to the Arctic Ocean. The survey will result in a comprehensive map of bathymetry and gravity of the Chukchi Borderland and portions of the Lomonosov Ridge, Makarov Basin and Mendeleev Ridge. These areas are out of the normal operating range of aerogeophysics platforms and data from the region that are available to western scientists are extremely sparse. The proposed survey is designed to test current hypotheses of the geologic structure and tectonic development of the main geographic features of the region. Whether the hypotheses prove to be true or not, the data will fill a conspicuous gap in the geophysical data coverage in the Arctic Ocean Basin. Hence, the data collected will be valuable to determining the geologic and tectonic structure of the region and, in turn, will also be useful for evaluating tectonic models for the development of the region.
