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R/V Langseth号对白令海的考察是作为美国扩大大陆架项目（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。此次考察特定航次采用了海洋地球物理学技术，收集了多道地震（MCS）和海洋底部观测站（OBS）数据，旨在白令海区域内及以外，从约2000米等深线至领海基线350海里范围内，确定地质构造、地壳性质及沉积层厚度。该考察项目由美国地质调查局（U.S.G.S.）资助。
