Open AccessThe dispersal capacity of Mollusca—a test on the South Azorean Seamount Chain
This study investigates the molluscan fauna of the South Azorean Seamount Chain (SASC), which comprises several seamounts culminating in 300–1600 m depth, separated by distances less than 200 km. Material was ...

Open AccessTrophic ecology of Angolan cold-water coral reefs (SE Atlantic) based on stable isotope analyses
Cold-water coral (CWC) reefs of the Angolan margin (SE Atlantic) are dominated by Desmophyllum pertusum and support a diverse community of associated fauna, despite hypoxic conditions. In this study, we use carbo...

Open AccessCold-water coral framework architecture is selectively shaped by bottom current flow
The three-dimensional (3D) structure of habitat-forming corals has profound impacts on reef ecosystem processes. Elucidating coral structural responses to the environment is therefore crucial to understand cha...

Cold-Water Coral Reefs in the Oxygen Minimum Zones Off West Africa
The discoveries of large reefs within cold-water coral mound provinces revealed that the West African margin is a coral hotspot area in the Atlantic Ocean. The most striking observation is that cold-water cora...

A Global View of the Cold-Water Coral Reefs of the World
Cold-water corals (CWC) form reef structures in continental margin and seamount settings at tropical, temperate, and even some polar latitudes. This global distribution makes them more widespread than shallow-...

Norwegian Coral Reefs
Cold-water corals (CWC) in Norwegian waters have been known for more than two centuries, but direct studies of CWC reefs were first enabled with the introduction of new ROV (Remotely Operated Vehicle) technolo...

Life and Death of Cold-Water Corals Across the Mediterranean Sea
Deep-sea explorations performed over the last two decades have shown evidence of abundant living cold-water coral communities in the Mediterranean Sea. Many submarine canyons, escarpments, seamounts, and outer...

Open AccessMadrepora oculata forms large frameworks in hypoxic waters off Angola (SE Atlantic)
This study aims to map the occurrence and distribution of Madrepora oculata and to quantify density and colony sizes across recently discovered coral mounds off Angola. Despite the fact that the Angolan populatio...

Open AccessBioerosion ichnodiversity in barnacles from the Ross Sea, Antarctica
Breakdown of skeletal and lithic hard substrates by organisms, a process referred to as bioerosion, is part of the global carbon cycle and receives increased attention, but little is known about bioerosion in ...

Open AccessCold-water coral reefs thriving under hypoxia
Reefs formed by scleractinian cold-water corals represent unique biodiversity hot spots in the deep sea, preferring aphotic water depths of 200–1000 m. The distribution of the most prominent reef-building spec...

5 Messinian Salinity Crisis: What Happened to Cold-Water Corals?
The fate of bathyal coral communities prior, during and after the environmentally devastating Messinian Salinity Crisis is briefly reviewed. The Messinian Salinity Crisis has created a geologically short-terme...

Recent benthic foraminiferal assemblages from cold-water coral mounds in the Porcupine Seabight
Cold-water coral ecosystems are characterised by a high diversity and population density. Living and dead foraminiferal assemblages from 20 surface sediment samples from Galway and Propeller Mounds were analys...

Open AccessHeterozoan carbonates in subtropical to tropical settings in the present and past
Water temperature has received considerable attention as steering factor for the genesis of different types of marine carbonate sediments. However, parameters other than temperature also strongly influence eco...

Franken Mound: facies and biocoenoses on a newly-discovered “carbonate mound” on the western Rockall Bank, NE Atlantic
Cold-water coral carbonate mounds are widespread along the Irish continental margin. Whereas the Porcupine Seabight and the Rockall Trough are relatively well studied with regard to mound topography, coral cov...

Biogeographical distribution of Hyrrokkin (Rosalinidae, Foraminifera) and its host-specific morphological and textural trace variability
The parasitic foraminifer Hyrrokkin sarcophagapredominantly infests the cold-water coral Lophelia pertusaand the co-occurring bivalve Acesta excavata, showing a commensal or parasitic behaviour. It occurs also on...

Microstructure, growth banding and age determination of a primnoid gorgonian skeleton (Octocorallia) from the late Younger Dryas to earliest Holocene of the Bay of Biscay
A fossil primnoid gorgonian skeleton (Octocorallia) was recovered on the eastern Galician Massif in the Bay of Biscay (NE Atlantic) from 720 m water depth. The skeleton shows a growth banding of alternating Mg...

From sediment to rock: diagenetic processes of hardground formation in deep-water carbonate mounds of the NE Atlantic
Modern cool-water carbonate mounds topped by corals form an extended reef belt along the NW European continental margin at 200–1200 m water depth. An essential element of mound growth are hardgrounds which pro...

Plectroninia celtica n. sp. (Calcarea, Minchinellidae), a new species of “pharetronid” sponge from bathyal depths in the northern Porcupine Seabight, NE Atlantic
Recent pharetronid sponges were regarded as relict species in tropical and subtropical waters, inhabiting cryptic habitats on coral reefs and in caves. More recent findings of a new species of the genus Plectroni...
