British Geological Survey (BGS) Geophysical Survey 1985/6: Peach (26/May/1985 to 29/Jun/1985)

This British Geological Survey (BGS) marine geophysical survey took place in May and June 1985 to the west of Scotland 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 part of the Peach sheet. Sea floor data were collected using echosounder and transit sonar. Sub-bottom seismic profiling data were collected using Airgun/Water gun; Pinger; Sparker and surface tow Boomer. Gravity and Magnetometer data were recorded. These records are archived by BGS. Technical details of the survey are contained in BGS report WB/89/11R.本数据集源自英国地质调查局（British Geological Survey, BGS）于1985年5月至6月在苏格兰西部海域开展的海洋地球物理勘测，本次勘测搭载船只为MV Gorsethorn。本次勘测作为英国大陆架勘测计划的组成部分，旨在采集相关地球物理与地质数据，核心目标为对皮奇席状岩层（Peach sheet）的部分区域开展勘测。海底数据通过回声测深仪与行进式声纳采集；亚底地震剖面数据通过气枪震源/水枪震源、脉冲声源（Pinger）、电火花震源（Sparker）以及水面拖曳式Boomer震源采集。本次勘测还同步记录了重力与磁力计观测数据。所有勘测记录均由英国地质调查局（BGS）归档保存。本次勘测的技术细节详见BGS报告WB/89/11R。
