Processed MCS data on the Chukchi Shelf and Chukchi Borderland, Arctic Ocean, acquired by the R/V Marcus G. Langseth in 2011 (MGL1112).

This 2011 R/V Langseth expedition collected MCS data across the transition from the Chukchi Shelf to the Chukchi Borderland as part of the Chukchi Edges Project. The goals were to image the transition between these two continental blocks in order to constrain the history and timing of relative motion between them and to establish the time stratigraphy along seismic profiles. The survey collected multichannel seismic reflection data and sonobuoy data. This data set presents processed MCS data. Detail of the processing are explained in the paper by Ilhan and Coakley (2018). This program was funded by National Science Foundation award OPP-0909568 which paid for the acquisition, processing, and interpretation of the two-dimensional multi- channel seismic (MCS) reflection profiles.

2011年，“朗塞特号科考船（R/V Langseth）”执行的航次作为“楚科奇边缘项目（Chukchi Edges Project）”的组成部分，在楚科奇陆架（Chukchi Shelf）至楚科奇边缘地带（Chukchi Borderland）的过渡海域采集了多道地震（Multichannel Seismic, MCS）数据。本次航次的研究目标为对上述两个大陆块体间的过渡带开展成像工作，以约束二者相对运动的演化历史与时间节点，并建立地震剖面的时间地层格架。本次调查采集了多道地震反射数据与声纳浮标（sonobuoy）数据。本数据集提供了经过处理的多道地震数据，具体的处理细节详见Ilhan与Coakley于2018年发表的研究论文。本项目由美国国家科学基金会（National Science Foundation）资助，项目编号为OPP-0909568，该经费覆盖了二维多道地震（MCS）反射剖面的采集、处理与解释工作。
