        An array of sensors, including an HD camera mounted on a Fixed Underwater Observatory (FUO) were used to monitor a cold-water coral (Lophelia pertusa) reef in the Lofoten-Vesterålen area from. The pseudocolonial coral Lophelia pertusa (Scleractinia, Caryophylliidae) is a eurybathic, stenothermal cosmopolitan cold-water species. It occurs in two color varieties, white and red. L. pertusa builds vast cold-water coral reefs along the continental margins, which are among the most diverse deep-sea habitats. Microbiology of L. pertusa has been in scientific focus for only a few years, but.

      Lophelia pertusa is the most well-known cold-water coral (CWC) with cosmopolitan distribution at depths normally between 40 and m (Roberts et al., ). Hard substrate, local topography, temperature, current flow, and food supply have been cited as factors that can affect its distribution (Davies & Guinotte, ; Georgian, Shedd. Lophelia pertusa is the best-known deepwater coral species. L. pertusa prefers water temperatures between oC, dissolved oxygen concentrations above 3 ml/l, and salinity between 35 and 37 ppt. The influence of other factors, including pH, is not known.

      Deep-sea corals in Southern California are diverse and abundant but subject to multiple stressors, including bottom-contact fisheries using mobile and fixed gear. There is a need for more information on the distribution of these taxa in relation to the distribution of demersal fishing effort, and the distribution of marine protected areas, in order to improve spatial planning.

In the Gulf of Mexico, Lophelia pertusa seemed restricted to aragonite saturated waters but given the lack of correlation between this species’ presence and the aragonite saturation level, Lunden, Georgian & Cordes () suggested that depth or other factors were more likely to control the coral’s by:   Vertical and horizontal distribution of Lophelia pertusa (Linné) in Trondheimsf jorden on the west coast of Norway.

The wall grows by simultaneous upward extension and outward thic. Little is known about species distribution patterns in deep-sea environments, primarily because sampling surveys in the high seas are expensive and time consuming.

The increasing need to manage and protect vulnerable marine ecosystems, such as cold-water corals, has motivated the use of predictive modelling tools, which produce continuous maps of potential species or habitat distribution from.

Lophelia pertusa is widely distributed, occurring in the Atlantic, Pacific, and Indian Ocean, and the normally have a similar vertical range, whereas the Lophelia rubble-zone has a narrower depth range and a scale distribution of species within Lophelia-reefs are needed to understand the habitat requirements of the.

The life cycle of many marine benthic species includes a pelagic larval stage that governs the connectivity between populations.

Larval transport is a function of hydrodynamic and biological processes. Knowledge of how larval traits affect dispersal will increase the accuracy of biophysical models used to predict connectivity, and is of paramount importance for management and conservation.

Regions of the upper slope of the Northern Gulf of Mexico harbor several deep‐water reefs structured by the scleractinian Lophelia pertusa.
