Abstract
    The FWO MINIMOUND project (2013-2016) aims to investigate small fossil cold-water coral (CWC) mounds within the Bay of Biscay in order to determine the impact of: (1) palaoeceanographic changes related to glacial-interglacial climate change in the last 15ka, (2) hydrocarbon related processes (seepage) and (3) anthropogenic fishing activities on CWC habitats. A better understanding of these mini-mounds will provide insight in the mechanisms of mound initiation and build up to large CWC mounds (e.g. Challenger Mound). The project will target three mini-mound provinces: the Explorer and Dangeard Canyons on the Celtic Margin, the Guilvinec Canyon on the Armorican Margin and the Upper Ferrol Canyon on the Cantabrian Margin. In these provinces USBL guided cores will be acquired to allow for sedimentological, palaeoceanographic and biogeochemical analyses throughout the minimounds. In addition, video dropframe acquisition will allow for habitat mapping and predictive modelling of the CWC habitats.
