Report: Brett, CP. 1981. Operations Report on Project 81/05. A Geophysical Survey in the Eastern English Channel. (IGS Report No 121) There were two objectives of this project, the first being to complete the regional survey of the Dungeness-Boulogne sheet of the IGS 1:250000 map series. The second objective was to carry out a gravity and megnetic survey in the Caen and Rouen sheets, in order to complete the gravity coverage of the entire English Channel. A secondary objective was to run a few isolated gravity lines in Bournemouth Bay and off Dartmouth to fill in small gaps in the existing data.报告：Brett, C.P.，1981年。《81/05号项目工作报告：英吉利海峡东部地球物理勘测》（IGS报告第121号）。本项目设有两项主要目标：其一为完成IGS 1:250000比例尺地图系列中邓杰内斯-布洛涅幅的区域勘测工作；其二为在卡昂幅与鲁昂幅区域开展重力与磁法勘测，以实现英吉利海峡全域重力数据覆盖。此外，本项目还设有一项次要目标：在伯恩茅斯湾及达特茅斯近海布设若干孤立重力测线，填补现有数据中的零星空白。
