Ocean bottom seismometer (OBS) data in the Bering Sea acquired during R/V Marcus G. Langseth expedition MGL11111 (2011)

This 2011 R/V Langseth survey of the Bering Sea was part of the U.S Extended Continental Shelf Project (http://continentalshelf.gov/) to establish the full extent of the U.S. continental shelf, consistent with international law. This particular leg used marine geophysics, collecting MCS and OBS data, in the Bering Sea for the purpose of determining geologic framework, crustal nature and sediment thickness within and beyond the U.S. EEZ, from 2000m isobath (approx.) to 350 nm from the territorial baselines. Funded by the U.S.G.S.

2011年，美国Langseth号研究船对白令海的考察是U.S. Extended Continental Shelf Project（美国大陆架扩展项目，http://continentalshelf.gov/）的一部分，旨在与国际法相一致，确立美国大陆架的全貌。此次特定航次运用海洋地球物理学方法，收集了MCS和OBS数据，在白令海进行考察，旨在确定美国专属经济区内外以及从约2000米等深线至距领海基线350海里范围内的地质结构、地壳性质和沉积层厚度。该项目由美国地质调查局（U.S.G.S.）资助。
