British Geological Survey (BGS) Geophysical Survey 1984/6: Northwest of Scotland (26/06/1984 to 19/08/1984)

This British Geological Survey (BGS) marine geophysical survey took place in June to August 1984 to the west of the Hebrides on board the MV Gorsethorn. The purpose was to collect data as part of the UK continental shelf survey programme. The objective was to survey the St. Kilda sheet and part of the Little Minch sheet. Sea floor data were collected using echosounder and sidescan sonar. Sub-bottom seismic profiling data were collected using Airgun, Pinger and Sparker. Gravity and Magnetometer data were recorded. These records are archived by BGS. Technical details of the survey data are contained in BGS report WB/89/6R.本次英国地质调查局（British Geological Survey, BGS）的海洋地球物理调查于1984年6月至8月在赫布里底群岛以西海域开展，作业船舶为MV Gorsethorn。本次调查作为英国大陆架调查计划的组成部分，旨在采集相关数据，勘测目标涵盖圣基尔达地质图幅（St. Kilda sheet）及小明奇海峡地质图幅（Little Minch sheet）的部分区域。调查采用回声测深仪（echosounder）与侧扫声呐（sidescan sonar）采集海底数据，通过气枪（Airgun）、脉冲震源（Pinger）及火花震源（Sparker）获取浅地层剖面地震数据，并同步记录重力与磁力仪数据。上述调查资料由BGS归档留存，其技术细节详见BGS报告WB/89/6R。
