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.

本数据集源自2011年朗塞思号（R/V Langseth）科考船在白令海开展的考察作业，该作业作为美国外大陆架计划（U.S Extended Continental Shelf Project，http://continentalshelf.gov/）的组成部分，旨在依据国际法确定美国大陆架的完整覆盖范围。本次考察航段采用海洋地球物理方法，在白令海范围内采集多道地震（Multi-Channel Seismic, MCS）与海底地震仪（Ocean Bottom Seismometer, OBS）数据，用于查明美国专属经济区（Exclusive Economic Zone, EEZ）内外的地质构造框架、地壳属性与沉积物厚度，考察覆盖范围从约2000米等深线至领海基线外350海里（nautical mile, nm）。本项目由美国地质调查局（U.S.G.S.）资助。
