This annex to the U.S. Northeast chapter in “The State of Deep-Sea Coral and Sponge Ecosystems of the United States” provides a revised and updated list of deep-sea coral taxa in the Phylum Cnidaria, Class Anthozoa, known to occur in U.S. waters from Maine to Cape Hatteras. The total number of distinct deep-sea corals documented for the U.S. Northe...
Deep-sea coral habitats, comprising mostly Lophelia pertusa (Linnaeus 1758), are well developed on the upper and middle continental slope off the southeastern United States (SEUS). These habitats support a diverse and abundant invertebrate fauna, yet ecology and biology of most of these species are poorly known. Ten cruises conducted off the SEUS (...
Two workshops with subject matter experts in the appropriate fields, were held in November and December 2021 to elicit guidance and feedback from the broader mesophotic and deep benthic scientific community. These workshops focused on best practices/approaches and identifying data gaps relative to habitat assessment and evaluation goals of the Meso...
This report details activities undertaken between 2016-2019, under the National Oceanic and Atmospheric Administration (NOAA) Deep Sea Coral Research and Technology Program's Southeast Deep Coral Initiative in the U.S. Southeast region. This project conducted included activities in the U.S. Caribbean, Gulf of Mexico, and U.S. Southeast during 21 re...
Deep-sea corals (DSCs) are important living marine resources, forming both oases of biodiversity and three-dimensional habitat structure for fishes and invertebrates. However, because of logistical difficulties and expense of deep-sea exploration, much less is known about the distribution of DSCs than is known for their shallow-water counterparts....
Marine hydroids are important benthic components of shallow and deep waters worldwide, but their taxonomy is controversial because diagnostic morphological characters to categorize taxa are limited. Their genetic relationships are also little investigated. We tested taxonomic hypotheses within the highly speciose superfamily Plumularioidea by integ...

region (Figure 1). The list covers azooxanthellate, heterotrophic coral species that occur predominantly deeper than 50 m in U.S. waters from Maine to Cape Hatteras. Details are provided on depth ranges and known geographic distribution within the region (Table 1). The list is adapted from Packer et al. (2007) with the addition of new species and r...
This NOAA report outlines the objectives and activities of the Southeast Deep Coral Initiative (SEDCI). The initiative is a coordinated, cross-line office effort that includes partners from NOAA Fisheries, Ocean and Atmospheric Research, and National Ocean Service; and aims to collect scientific information needed to manage deep-sea coral ecosystem...
Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods, and services they provide to human populations, and the impacts that human activities have on their over...
Although deep-sea octocorals were historically considered common components of hard bottom communities in the deep waters of the Gulf of Maine region, they are now spatially rare and have been difficult to detect using standard towed-gear surveys. Exploratory ROV and towed camera surveys in 2002-03 and 2013-15 located sites in deep U.S. waters (ca....
The common sea pen (Pennatula aculeata) is a deep, cold-water coral in the soft sediments of the Gulf of Maine, often occurring in dense patches. While providing physical habitat structure, it is routinely removed as bycatch during commercial fishing activities. A study in Atlantic Canada (Baillon et al. 2012) examined sea pens from trawl bycatch a...
Squat lobsters (Galatheoidea and Chirostyloidea), a diverse group of decapod crustaceans, are ubiquitous members of the deep-sea fauna. Within Galatheoidea, the genera Munida and Munidopsis are the most diverse, but accurate estimates of biodiversity are difficult due to morphological complexity and cryptic diversity. Four species of Munida and nin...
The continental margin off the northeastern United States (NEUS) contains numerous, topographically complex features that increase habitat heterogeneity across the region. However, the majority of these rugged features have never been surveyed, particularly using direct observations. During summer 2013, 31 Remotely-Operated Vehicle (ROV) dives were...
White paper regarding exploration for and conservation of deep sea corals in Gulf of Maine
Seven National Oceanic and Atmospheric Administration and United States Geological Survey expeditions employed manned submersibles or remotely operated vehicles to explore deep-sea coral and cold seep habitats in the northern central Gulf of Mexico continental slope, off Mississippi
and Louisiana. Ten species of echinoids and 21 species of holothur...
Newly collected specimens of the Atlantic Myxaster sol and a further record of Pythonaster atlantidis add to the known occurrence records and the morphological variation of these rarely encountered species. Distribution data suggests that both M. sol and P. atlantidis are pan-Atlantic species and are similar to other widely distributed deep-sea ast...
The Northeast Regional Office (NERO) and the Northeast Fisheries Science Center (NEFSC), in collaboration with the New England and Mid-Atlantic Fisheries Management Councils (NEFMC and MAFMC, respectively) and NOAA’s Deep-Sea Coral Research and Technology Program (DSCRTP), is developing and implementing a strategy for conserving deep-sea corals (DS...
Deep-sea corals provide important habitat for many organisms; however, the extent to which fishes and other invertebrates are affiliated with corals or other physical variables is uncertain. The Cape Fear coral mound off North Carolina, USA (366–463 m depth, 33° 34.4′N, 76° 27.8′W) was surveyed using multibeam sonar and the Johnson-Sea-Link submers...

Hydroids are a species-rich component of the benthic fauna inhabiting deep, cold-water coral habitats. Fertile colonies of the leptothecate species Halecium macrocephalum Allman, 1877 collected from cold-water coral habitats off the southeastern USA exhibited morphologically peculiar male gonophores, distinct from those described and illustrated fo...
A new deep-water species of the snapping shrimp genus Alpheus Fabricius, 1798 is described from two offshore localities in the northern Gulf of Mexico, south of Louisiana. Alpheus lentiginosus n. sp. belongs to the A. macrocheles (Hailstone, 1835) species group and is most closely related to the western Atlantic A. pouang Christoffersen, 1979 and A...
Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal ability or population connectivity in Lophelia pertusa, the dominant framework-forming coral on the continental slope in the North Atlantic Ocean. Using nine microsatellite DNA markers...
The Hippasterinae is a subfamily within the Goniasteridae, consisting of five genera and 26 species, which occur in cold-water settings ranging from subtidal to abyssal depths. All known genera were included in a cladistic analysis resulting in two most parsimonious trees, supporting the Hippasterinae as monophyletic. Our review supports Sthenaster...
Taxonomic and ecological interest in squat lobsters has grown considerably over the last two decades. A checklist of the 870 current valid species of squat lobsters of the world (families Chirostylidae, Galatheidae and Kiwaidae) is presented. The compilation includes the complete taxonomic synonymy and geographical distribution of each species plus...
Deep-water coral habitats off the southeastern USA (SEUS) support diverse fish and invertebrate assemblages, but are poorly explored. This study is the first to report on the hydroids collected from these habitats in this area. Thirty-five species, including two species that are likely new to science, were identified from samples collected primaril...
The occurrence and relative abundance of tissue (arm) regeneration in the ophiuroid, Ophiacantha bidentata (Retzius), was examined in individuals collected primarily among colonies of the deep-water coral Lophelia pertusa off the southeastern United States. Seven deep-water coral sites (384–756m), located between Cape Lookout, NC, and Cape
Canavera...
Lophelia pertusa, a cosmopolitan species, is the dominant structure-forming scleractinian coral on the continental slope in the western North Atlantic Ocean (WNAO) off of the southeastern U.S. coast and in the Gulf of Mexico (GOM). Little is known about this coral's basic biology, including larval dispersal and population connectivity, yet adverse...

... Estuarine emergent wetlands (both native and invasive sub-classes) were assessed separately in the Mid-Atlantic and New England because biogeographic differences in coastal wetlands and/or the rate of SLR could result in differential climate vulnerabilities for this habitat. Deep sea coral and sponge habitats were split between the Gulf of Maine and the areas farther offshore on the Northeast U.S. Continental Shelf, slope, submarine canyons, and seamounts to assess potential differences in climate vulnerability associated with coral and sponge habitat density, depth, biodiversity, population genetics, and anthropogenic drivers such as impacts from fishing gear [65,[94][95][96][97][98]. ...
... Given species' geographic locations and environmental information, the ecological niche modeling approach such as MaxEnt, random forest, and generalised additive modeling (Phillips et al., 2006;Melo-Merino et al., 2020;Valavi et al., 2022), have been widely used as powerful tools for predicting current and future species distributions. The most commonly used climatic RCP scenarios, such as minimum 2.6, moderate 4.5, and extreme 8.5 carbon emissions (IPCC, 2014), are generally used to predict the future climatic suitability of species across space (Elith et al., 2011;Saeedi et al., 2017;Freeman et al., 2013;Bargain et al., 2017;Kinlan et al., 2020;Pittman and Brown., 2011;Simões et al., 2021). Coral reefs are considered one of the most important and fastestresponding indicators of climate change, as they bleach and perish during marine heat waves (Roberts and Cairns., 2014;Hughes et al., 2018;Guan et al., 2020;Guo et al., 2020;Anthony et al., 2020;Chen, 2021). ...
... Moreover, fixation of the gelatinous medusae and the soft-bodied polyps can lead to shrinkage and deformation of fragile specimens leading to distortion of morphological diagnostic features (Häussermann, 2004;Schuchert, 2012;Holst and Laakmann, 2014;Holst et al., 2019). Molecular genetic techniques have been widely tested and applied for identification and differentiation of cnidarian species (Holst and Laakmann, 2014;Moura et al., 2018;Holst et al., 2019;Bucklin et al., 2021). However, not in all groups, standard fragments such as the COI barcode regions are fully informative on species level (Brugler et al., 2018;Schuchert, 2020). ...

... Indeed, Blanes Canyon's higher dynamism promotes diversity (both for bacterial and archaeal taxa pools) and community heterogeneity. The complex topography and strong, variable currents characterising submarine canyons enhance marine landscape diversity at regional scales, providing singular habitats to a highly diverse fauna (Huvenne and Davies, 2014;Fernandez-Arcaya et al., 2017;Ismail et al., 2018). In Blanes Canyon, high-rank taxa showed similar profiles to the open slope, but only 37% of the OTUs were shared. ...
... Munidopsis similis was described from southern New England and recorded from the Middle Atlantic Bight, West of Iceland and the Gulf of Mexico (Smith 1885;Hansen 1908;Wenner 1982;Coykendall et al. 2017). Marin (2020) described a new taxon, M. asiatica, from the Bering Sea, reported as morphologically and genetically very similar to M. similis (see Marin 2020). ...
... Only a few species of Alpheus occur in temperate or cool-temperate waters, occurring as far north as eastern Russia and northern Japan, or as far south as New Zealand and southern Chile (Banner and Banner, 1982;Kim and Abele, 1988;. A number of species occur in deep water, well below 100 m and down to at least 1000 m (Anker and Nizinski, 2011;Scioli and Anker, 2020). They also occupy a wide variety of microhabitats, ranging from coral reef crevices, burrows in mud or sand, spaces under rocks, coralline algae, mangrove roots, tide pools etc.; some species are well-known bioeroders of both living and dead corals (Banner and Banner, 1982;Werding, 1990;Anker et al., 2006;Anker and De Grave, 2016). ...
... The deep sea has long been considered to be fairly homogeneous with broad distributions of deep-sea species across large areas (McClain & Hardy, 2010), but though the deep sea is large, it is not abiotically or biologically uniform . The deep sea hosts distinct biological communities that have adapted to the abiotic conditions in each deep water habitat, including submarine canyons (Fernandez-Arcaya et al., 2017;Quattrini et al., 2015) seamounts (Clark et al., 2010;Morato et al., 2008;Shank, 2010), hydrothermal vents Van Dover, 2021) and cold-water coral reefs (Roberts et al., 2009). However, the ability to fully interrogate the abiotic preferences of biological communities has only recently emerged, thanks to burgeoning technology that is only now becoming more accessible Ramirez-Llodra et al., 2010;Webb et al., 2010) Modern access to the deep sea has started to yield large basin-wide datasets (e.g. ...
... Rising temperatures and ocean acidification are negatively impacting shallow and deep sea corals [16,17,64]. Loss of live coral cover is related to decreases in abundance of a number of fish species; the magnitude of decline has been associated with the dependence on live coral [64][65][66][67]. ...
... This is peculiar because echinoderms, and especially echinoids, are rarely reported living at seeps (e.g. Carney, 2010;Pawson et al. 2015) or as fossils from ancient seeps (e.g. Kato et al. 2017;Brezina et al. 2022). ...
