Chukchi Sea Bathymetry

Bathymetric contours were generated from soundings collected during geophysical surveys conducted by the USGS from 1969 to 1982, and supplemented by data from other sources. The region covered by the map is the Chukchi Sea from the Bering Strait north to the Arctic Ocean, and Point Barrow, Alaska west to Herald Island, Russia. The map stops just east of Wrangel Island, Russia. Bathymetry is in meters, including 10 meter contour intervals from 10 to 100 meters, and 100 meter contour intervals at depths greater than 100 meters.本数据集的水深等值线（bathymetric contours）由美国地质调查局（USGS）1969年至1982年开展的地球物理勘测所采集的测深数据生成，并补充了其他来源的相关资料。该地图覆盖的海域为楚科奇海（Chukchi Sea）：北起白令海峡（Bering Strait）延伸至北冰洋（Arctic Ocean），西起阿拉斯加（Alaska）巴罗角（Point Barrow）延伸至俄罗斯赫拉德岛（Herald Island）；其东界止于俄罗斯弗兰格尔岛（Wrangel Island）东侧。本次数据的水深单位为米，其中10米至100米深度区间采用10米等值线间距，100米以上深度区间采用100米等值线间距。
