British Geological Survey (BGS) Geophysical, Multibeam and Sampling Survey 2011/3: North Channel & Hebrides: (17/Apr/2011 to 05/May/2011)

This British Geological Survey (BGS) marine multibeam, geophysical and sampling survey took place in April/May 2013 onboard the RRS James Cook. Data was collected from the North-Western Approaches area, incorporating the Sea of the Hebrides, Malin Sea and North Channel region, and extending landwards into sea lochs, including Loch Linnhe and Loch Scavaig. Sea-bed samples were collected using 15m rock drill, vibrocorer and piston corer. Sub-bottom seismic profiling data were gathered using the SBP120 installed in the RRS James Cook. MSCL data was measured by the University of Leicester. Most of the acoustic data were recorded digitally, but paper records were generated also. In additional to the initial work plan, a multibeam bathymetry dataset was acquired from the Sound of Kilbrannan. All the samples are archived by BGS except six piston core working halves were taken by Scottish Association for Marine Science (SAMS) for further study. Technical details of the survey are contained in the BGS Report of Survey.

此次由英国地质调查局（British Geological Survey，简称BGS）执行的海洋多波束、地球物理及采样调查于2013年4月至5月在RRS James Cook号船上进行。数据采集自西北通道区域，包括赫布里底海、马尔钦海以及北海峡地区，并向内陆延伸至包括林内湖（Loch Linnhe）和斯科维尔湖（Loch Scavaig）在内的海 Lochs。海底样品通过15米岩石钻、振动柱状钻和活塞柱状钻采集。使用安装在RRS James Cook号船上的SBP120设备收集了海底地震剖面数据。MSCL数据由莱斯特大学测量。大部分声学数据以数字形式记录，同时亦产生了纸质记录。除了最初的调查计划之外，还从基尔布兰南海峡获得了多波束测深数据集。所有样品均由BGS存档，除六份活塞柱状钻工作半份由苏格兰海洋科学协会（Scottish Association for Marine Science，简称SAMS）取走以供进一步研究外。此次调查的技术细节包含在BGS的调查报告之中。
