“…Two mounds are elongated WNW-ESE, and one set of small mounds is lined up in a north-south direction. The largest mound in the central cluster (often referred to as the 'Propeller mound': De Mol 2002; Dorschel et al 2005;Dorschel et al 2006;Rü ggeberg et al 2005Rü ggeberg et al , 2006 consists of a north-south trending ridge, forking towards the north into ENE and WNW-ward pointing branches. The western branch then connects to another long ENE directed ridge.…”

Cold-water coral carbonate mounds, owing their presence mainly to the framework building coral Lophelia pertusa and the activity of associated organisms, are common along the European margin with their spatial distribution allowing them to be divided into a number of mound provinces. Variation in mound attributes are explored via a series of case studies on mound provinces that have been the most intensely investigated: Belgica, Hovland, Pelagia, Logachev and Norwegian Mounds. Morphological variation between mound provinces is discussed under the premise that mound morphology is an expression of the environmental conditions under which mounds are initiated and grow. Cold-water coral carbonate mounds can be divided into those exhibiting ''inherited'' morphologies (where mound morphology reflects the morphology of the colonised features) and ''developed'' morphology (where the mounds assume their own gross morphology mainly reflecting dominant hydrodynamic controls). Finer-scale, surface morphological features mainly reflecting biological growth forms are also discussed.

“…These time spans appear to be long enough for allowing the stabilization of the favorable paleoceanographic conditions that concurred to the colonization of the newly suitable substratum offered by the extruded mud breccia and to the consequent coral development. Low sedimentation rates due to stronger currents are one of the favorable factors for coldwater coral ecosystem development, as corals must sufficiently keep-up with hemipelagic sedimentation Dorschel et al, 2005;Rüggeberg et al, 2005Rüggeberg et al, , 2007. In both mud volcanoes the coral-rich layer correspond to lower sedimentation rate values, e.g.…”

The Dhaka and Maya mud volcanoes (MVs), located in the Mud Diapir Province in the Western Alboran Basin along the Moroccan Coasts, were cored during the TTR-17, Leg 1 cruise. Cores were taken on the top of the volcanoes at a water depth of 370 m on the Dhaka MV (core TTR17-MS411G) and at 410 m water depth on the Maya MV (core TTR17-MS419G), respectively. On both mud volcanoes the extruded mud breccia provides the nucleation point for the colonization and development of cold-water corals and associated ecosystems. Two phases of cold-water coral growth are observed: (1) between slightly older than 4175± 62 years BP and around 2230± 59 years BP at Dhaka, and (2) between slightly older than 15583 ± 185 years BP and around 7613 ± 38 years BP at Maya MV. On the top of the Maya MV only a small patch reef and/or isolated corals proliferated, whereas a more extended patch reef colonized the top of the Dhaka MV. At both sites the cold-water coral development was triggered by the availability of a suitable substrate for initial coral settling, provided either as a firm ground or as single clasts. Subsequently coral growth was supported by enhanced nutrient flux possibly related to upwelling and/or strong currents. During the intervals of coral growth planktonic foraminiferal assemblages were dominated by Neogloboquadrina incompta. The decline of coral ecosystems on the mud volcanoes is accompanied at surface by a shift from the N. incompta dominated assemblage to a Globorotalia inflata dominated assemblage, possibly reflecting more oligotrophic conditions. This shift is coeval to the passage from wet to arid conditions at the end of the African Humid Period at Maya MV. It is interpreted as an effect of an early human impact on a fragile environment, which was already stressed by desiccation at the time of the development of complex human society along the Mediterranean coasts, at Dhaka MV.

“…Recent carbonate mounds stand as natural laboratories to link the build-up history and architecture to high-resolution sequence stratigraphy. Several studies in recent years have described environmental parameters controlling the growth and development of cold-water coral carbonate mounds on the North-east Atlantic continental margin (De Mol et al, 2002;Dorschel et al, 2005;Rüggeberg et al, 2005;Dorschel et al, 2007;Rüggeberg et al, 2007;Van Rooij et al, 2007;Huvenne et al, 2009;Margreth et al, 2009;Mienis et al, 2009;Van Rooij et al, 2009, among others).…”

Carbonate mounds in shallow and deep time

Over a decade of research on recent cold-water coral mounds in various oceans has set the stage for comparative studies between recent and ancient carbonate mound systems, with the aim to unravel generic processes and reveal the "red thread" in a fundamental strategy of Life building Geology -a strategy nearly as ancient as Life itself. Natural laboratories have been identified in the present ocean, which provide new insights in oceanographic controls on species migration and settlement, in the interaction of currents and carbonate build-up, in the earliest diagenesis which overprints environmental signals and shapes the template of compartmentalization of carbonate build-ups, and in so many other processes and factors ultimately shaping carbonate bodies, comparable in size and properties to the large-scale carbonate hydrocarbon reservoirs in the geological record. Ocean drilling and coring is an essential component of this research. Ideally, this process is a two-way avenue between Shallow and Deep Time, where fundamental and industrial knowledge about fossil carbonate mounds can drive further investigations and even experimentation in the present seas, while the discoveries and process studies on "live" systems can yield new insights in the architecture and evolution of ancient reservoir systems. This bridging exercise is the quintessence of COCARDE (Cold-Water Carbonate Reservoir Systems in Deep Environments), an international network under the auspices of IOC-UNESCO (http://www.cocarde.eu). COCARDE has organised two workshops in 2009, with a significant support of European programmes (e.g. ESF Magellan workshop series) and partner projects (e.g. ESF EuroDIVERSITY project MiCROSYSTEMS). This special issue groups 12 papers, all addressing observations which by their nature have the potential to provide keys to generic processes, of relevance for past carbonate systems. As COCARDE proceeds, it is the objective to "reciprocate" in near future with an equivalent grouping of contributions from the study of fossil studies, to guide further research in the present ocean. It is the purpose of COCARDE to strengthen such a reflux from the studies of fossil systems by stimulating relevant continental drilling exercises, with comparable sampling protocols, resolution and analytical procedureswhere relevant -to allow direct comparisons with records from ocean drilling. The papers in this special issue have been structured in four themes: (i) keys to palaeoenvironmental control, (ii) mound initiation, growth and demise, (iii) of microbes and mounds, and (iv) tracking organomineralsRecent and Ancient.
