“…labile organic matter) and sediment particles, the local hydrographic and near-bed hydrodynamic setting defines the success of cold-water coral growth and, therefore, of mound development (e.g. De Mol et al, 2002;Freiwald et al, 2004;Roberts et al, 2006Roberts et al, , 2009Dorschel et al, 2007;Duineveld et al, 2007;Foubert et al, 2007;Mienis et al, 2007Mienis et al, , 2009aMienis et al, , 2012Rüggeberg et al, 2007;Wheeler et al, 2007Wheeler et al, , 2008Dullo et al, 2008;Davies et al, 2009;Huvenne et al, 2009a,b;Thierens et al, 2010;White and Dorschel, 2010;Wienberg et al, 2010;Pirlet et al, 2011).…”

“…Hence, climatically-induced hydrodynamic changes e and late Quaternary glacialeinterglacial fluctuations in bottom-current regime and water-column stratification in particular e are considered to govern recent coral carbonate mound development along the Irish Atlantic margin (e.g. Dorschel et al, 2005;Foubert et al, 2007;Rüggeberg et al, 2007;Mienis et al, 2009b;White and Dorschel, 2010;Pirlet et al, 2011). In this context, the presence, position and highly-energetic flow of MOW during Late Pleistocene and Holocene interglacial/ interstadial periods is often used to explain the success of coral carbonate mound growth in the Porcupine Seabight during these 'warm' periods (e.g.…”

“…Similarly, sediment sequences from piston and gravity cores through sub-recent mound units have been analysed to infer late Quaternary palaeo-environmental conditions along the NW European continental margin (e.g. Rüggeberg et al, 2007;Wienberg et al, 2010;Pirlet et al, 2011). However, the fragmented nature and low resolution of late Quaternary mound sequences, rich in hiati known to span up to several hundred thousand years (e.g.…”

We investigate the Holocene growth history of the Mingulay Reef Complex, a seascape of inshore cold-water coral reefs off western Scotland, using U-series dating of 34 downcore and radiocarbon dating of 21 superficial corals. Both chronologies reveal that the reef framework-forming scleractinian coral Lophelia pertusa shows episodic occurrence during the late Holocene. Downcore U-series dating revealed unprecedented reef growth rates of up to 12 mm a -1 with a mean rate of 3 -4 mm a -1 .Our study highlighted a persistent hiatus in coral occurrence from 1.4 ka to modern times despite present day conditions being conducive for coral growth. The growth history of the complex was punctuated at least twice by periods of reduced growth rates: 1.75 -2.8 ka, 3.2 -3.6 ka and to a lesser extent at 3.8 -4 ka and 4.2 ka. Timing of coral hiatuses and reduced reef growth rates at Mingulay were synchronous with those occurring across northern Europe. Our study suggests that large-scale shifts in 1 palaeoenvironmental regimes associated with changes to the North Atlantic subpolar gyre may control these ecosystems. IntroductionOne of the most widespread cold-water corals is the reef framework-forming scleractinian Lophelia pertusa, which to date is known from all oceans except the Southern Ocean ). In the NE Atlantic, Lophelia occurs preferentially along the European continental margin (De Mol et al., 2002;Kenyon et al., 2003;Wheeler et al., 2007) where it is often associated with areas of positive topographic relief such as banks, seamounts and ridges likely due to favourable environmental conditions (e.g. hydrology, food supply, current strength; Davies et al., 2008). Local hydrodynamics are crucial for coral dispersal and recruitment, preventing corals from being smothered by sediments, and as a food supply mechanism for sessile suspension feeders such as corals (Genin et al., 1986;Frederiksen et al., 1992;White et al., 2005;Mienis et al., 2007;White, 2007;Davies et al., 2009;Mienis et al., 2009).Some of the best-studied Lophelia reefs are those found on coral carbonate mounds that can grow hundreds of metres high and few kilometres long (Wheeler et al., 2007). Several models of coral carbonate mound ontogeny have been proposed to explain the initiation and development of such structures, which generally converge on the importance of a complex interaction between sediment accumulation and coldwater coral colonisation and growth under favourable environmental regimes (Henriet et al., 2001;De Mol et al., 2002;Dorschel, 2003;Roberts et al., 2006;Eisele et al., 2008; de Haas et al., 2008). The last 11 ka, as well as previous warm interglacial periods such as marine isotope stages (MIS) 5, 7 and 9, have been favourable for coral growth and thus coral carbonate mound development in the NE Atlantic between 50°N and 70°N (Frank et al., 2009;Douville et al., 2010;. To date no Lophelia from glacial periods have been found at these latitudes in the NE Atlantic (Dorschel, 2003;Kenyon et al., 2003;Schröder-Ritzrau et al., 2003;Fra...
