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

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. […]1948年，勒达努瓦（Le Danois）首次报道了欧洲大西洋大陆边缘沿线现存冷水珊瑚礁（cold-water coral reefs）——即法语所称的“massifs coralliens”（珊瑚礁群）——的存在。2008年，依托R/V Belgica号科考船的考察航次正式启动，旨在对比斯开湾加斯科涅沿岸的彭马尔克（Penmarc'h）峡谷与吉维尔内克（Guilvinec）峡谷内的冷水珊瑚开展重新调查。本次航次期间，研究人员采用多波束条带测深（multibeam swath bathymetry）、温盐深（CTD）剖面测量、遥控无人潜水器（ROV）观测以及超短基线（USBL）引导箱式取样等技术手段，对一片面积达560平方千米的海域展开了研究。[…]
