“…The deep-water corals (DWCs) often grow on carbonate mounds (e.g., Hovland et al 1994;Henriet et al 1998;Freiwald et al 1999De Mol et al 2002;Huvenne et al 2002 amongst others). They normally occur between 50 and 2000 m depth, typically at temperatures of 4-12ºC (Wilson 1979;Kenyon et al 1998Kenyon et al , 2003Rogers 1999;De Mol et al 2002, 2005, although they can tolerate sub-zero water temperatures for short periods of time (Bett 2000). L. pertusa, the dominant DWC, sometimes forms extensive reefs (e.g., Sula Ridge -Norwegian Shelf; Freiwald et al 1999, but more often occurs as small colonies of a few centimetres to a few metres across (e.g., Darwin Mounds -Northern Rockall Trough; Masson et al 2003).…”
