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.
For more detailed information on the acquisition equipment and data collection techniques, operational standards, data processing methods and quality control procedures used on this survey see the Report of Survey/Cruise Report and associated documentation where available.
