Bureau de Recherches Geologiques et Minieres (BRGM) Geophysical and Sampling Survey 1972/2: English Channel (18/May/1972 to 12/Jun/1972)

This marine geophysical and sampling survey undertaken as part of the GEOMANCHE Project to examine the geological structure of the Western English Channel (Manche) by Bureau De Recherches Geologiques et Minieres (BRGM,ORLEANS). It was called GEOMANCHE 72 and took place in May to June 1972 in the Western English Channel on board the M.V. Le Noroit. This was a joint French-British investigation of the western part of the Channel between the channel Islands and Start Point to produce a joint geological map of the central part of the western Channel. Data were gathered to evaluate the geological structure of the Western English Channel. Subsurface seismic data were gathered using a sparker. Seabed samples and cores were collected using a rock corer. These data are assumed to be archived by BRGM.

本海洋地球物理与采样调查作为GEOMANCHE项目的一部分，由地质与矿业研究局（Bureau De Recherches Geologiques et Minieres，简称BRGM，位于奥尔良）执行，旨在探讨英吉利海峡西部（Manche）的地质结构。此次调查命名为GEOMANCHE 72，于1972年5月至6月在英吉利海峡西部，乘坐M.V. Le Noroit号船只进行。这是一项法国与英国联合的调查，旨在对海峡群岛与Start Point之间的海峡西部进行联合地质图的编制。为评估西部英吉利海峡的地质结构，收集了相关数据。通过火花震源获取了地下地震数据，使用岩芯钻取器收集了海底样本和岩芯。据推测，这些数据已由BRGM存档。
