Sedimentology and age determination of sediment cores from the Penmarch'h and Guilvinec Canyons (Bay of Biscay)

In 1948, Le Danois reported for the first time the occurrence of living cold-water coral reefs, the so-called "massifs coralliens", along the European Atlantic continental margin. In 2008, a cruise with R/V Belgica was set out to re-investigate these cold-water corals in the Penmarc'h and Guilvinec Canyons along the Gascogne margin of the Bay of Biscay. During this cruise, an area of 560 km**2 was studied using multibeam swath bathymetry, CTD casts, ROV observations and USBL-guided boxcoring.
