Collaborative Research: Aerogeophysics in the Canada Basin

北冰洋的加拿大盆地仍然是地球上最不为人所知的地区之一，但了解它的演变对于了解海洋环流、气候生成的历史以及加拿大盆地阿拉斯加边缘包含世界上最大的碳氢化合物气田之一的事实非常重要。为了完成阿尔法海脊和门捷列夫海脊之间的加拿大盆地以及北极阿拉斯加/加拿大和远东西伯利亚边缘之间的航空地球物理覆盖，提议进行两个季节的航空地球物理。拟议工作的三个最重要的方面是：1)收集侦察航空地球物理数据，以便能够就北极加拿大盆地的构造演化提出具体的假设。2)将近海收集的航空地球物理数据与对北极阿拉斯加大陆架的高分辨率航空磁学调查结合起来。使用这两个数据集肯定会回答阿拉斯加北极地区海洋-大陆边界的性质问题。3)在楚科奇高原和埋藏的北楚科奇盆地的大陆边缘进行详细的重力测量，以深入了解这一边缘的演化。目前的数据不允许合理解释这一边际的演变。

The Canada Basin of the Arctic Ocean remains one of the least known regions of the earth, yet understanding it's evolution is important to understanding the history of ocean circulation, climate generation, as well as the fact that the Alaska margin of the Canada Basin contains one of the world's giant hydrocarbon fields. In order to complete the aerogeophysical coverage of the Canada Basin between the Alpha and Mendeleyev ridges and the Arctic Alaska/Canada and Far Eastern Siberia margins, two seasons of aerogeophysics are proposed. The three most important aspects of the proposed work are: 1) Collect reconnaissance aerogeophysical data that will allow specific hypotheses to be formulated about the tectonic evolution of the Canada Basin of the Arctic. 2) Combine the aerogeophysical data collected offshore with a high-resolution aeromagnetics survey of Arctic Alaska's continental shelf. Work with these two datasets should definitely answer the question of the nature of the Ocean-Continent Boundary along Arctic Alaska. 3) Survey in detail gravity over the Chukchi Plateau and onto the continental margin of what should be the buried North Chukchi Basin to allow insight into the evolution of this margin. Present data does not allow reasonable interpretation of the evolution of this margin.
