British Geological Survey (BGS) Geophysical Survey 1985/7: NW Continental Margin (29/Jun/1985 to 09/Jul/1985)

This British Geological Survey (BGS) marine geophysical survey took place in May and June 1985 in the NW continental margin on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The main objective was to survey a series of deep-tow boomer/sparker profiles down the West Hebridean and West Shetland slopes. Sea floor data were collected using echosounder; deep-tow sidescan sonar and transit sonar. Sub-bottom seismic profiling data were collected using pinger; deep-tow boomer and deep-tow sparker. Gravity data were recorded. These records are archived by BGS. Details of the survey data processing are contained in BGS report WB/89/12R.

本次由英国地质调查局（British Geological Survey，简称BGS）执行的海洋地球物理调查于1985年5月至6月在MV Gorsethorn号船上进行，地点位于西北大陆边缘。此次调查旨在收集数据，作为英国大陆架调查计划的一部分。主要目标是对西赫布里底岛和西设得兰岛的斜坡进行一系列深海拖曳式声纳/闪光器（deep-tow boomer/sparker）剖面测量。海底数据通过回声测深仪、深海拖曳式侧扫声纳和横波声纳收集。使用回声探测仪、深海拖曳式声纳和深海拖曳式闪光器收集海底以下地震剖面数据。同时记录了重力数据。这些记录均由BGS存档。关于调查数据处理的具体细节包含在BGS报告WB/89/12R中。
