This summer the coral Lophelia pertusa was found growing on oil platforms in the North Sea and on the Brent Spar oil-storage buoy during its decommissioning. The findings indicate that Lophelia has a wider distribution and a more rapid rate of growth than previously believed. The discovery also has implications for the debate over oil exploration in the Atlantic Ocean and the perceived benefits of onshore dismantling of deep-water platforms. 
The deep-water coral Lophelia pertusa in Norwegian waters: distribution and fishery impacts
The results show that the corals are abundant particularly on the mid Norwegian continental shelf between 200 and 400 m depth, and in general it seems that the largest densities are distributed along the continental break and at ridges of morainic origin.
Reef-Forming Cold-Water Corals
Coral reefs are something we usually associate with warm, tropical waters and exotic fish, but not with the cold, deep and dark waters of the North Atlantic, where corals were regarded as oddities on
A Time Series Study of Lophelia pertusa and Reef Megafauna Responses to Drill Cuttings Exposure on the Norwegian Margin
There were no observed degradations of reef structure over time, nor reductions of associate fauna abundance, regardless of modelled exposure concentration at any of the surveyed reefs, in a novel monitoring study focused exclusively on adult fauna.
In situ growth and bioerosion rates of Lophelia pertusa in a Norwegian fjord and open shelf cold-water coral habitat
A first estimate of the dimensions of both processes in natural cold-water coral habitats is given, indicating that calcium carbonate loss through bioerosion amounts to one fifth to one sixth of the production rates by coral calcification by way of accretion–bioerosion.
Morphology and sedimentology of (clustered) cold-water coral mounds at the south Rockall Trough margins, NE Atlantic Ocean
Cold-water coral mounds on both margins of the Rockall Trough (NE Atlantic Ocean) have a strongly different morphology. Single, isolated mounds occur on the SE margin and are mainly found on the
Postglacial carbonate production by cold-water corals on the Norwegian Shelf and their role in the global carbonate budget
Cold-water coral reefs have been neglected in calculations of global carbonate production. We present the first calculations of the amount of CaCO 3 produced by cold-water corals on the Norwegian
Calcification of the cold-water coral Lophelia pertusa, under ambient and reduced pH
Calcification rates and skeletal growth of young and fast calcifying corallites suffered more from ocean acidification, Nevertheless, L. pertusa exhibited positive net calcification even at an aragonite saturation state (Ωa) below 1.3 units.

A compilation has been made of new data on the distribution of the deep-water coralLophelia pertusa(L.) derived from trawling records, grab and dredge stations and submersible dives, together with
Ahermatypic coral banks off mid-Norway; evidence for a link with seepage of light hydrocarbons
Large (up to 31-meter high) coral banks (or bioherms) occur on the continental shelf off mid-Norway at water depths between 220 and 310 meters. They are built up by the cold-water, ahermatypic,
Oxygen and carbon isotope ratios related to growth line patterns in skeletons of Lophelia pertusa (L) (Anthozoa, Scleractinia): Implications for determination of linear extension rate
The results indicated that isotopic fractionation in Lophelia is controlled by kinetic isotope effects, and the shape of the δ180 curve along the growth axis in the septa was almost parallel with the curve of sea water temperatures.
