Cold-water coral and sponge communities are important indicators of vulnerable marine ecosystems and are used to delineate areas for marine conservation and fisheries management. Here, we used a diverse set of environmental data layers (n=30) representing a range of bathymetric derivatives, physicochemical variables, and water column properties to assess the primary factors influencing the niche separation and potential distributions of six habitat-forming groups of cold-water coral and sponge in the northeast Pacific region of Canada

NOAA’s Office of Habitat Conservation (OHC) in the National Marine Fisheries Service is participating in an Open Ocean Trustee Implementation Group studying marine life in the Gulf of Mexico and the impact of the Deepwater Horizon (DWH) oil spill on that life. The NOAA Central Library was consulted to create this annotated bibliography to provide OHC with literature on the mesophotic and deep sea corals in the Gulf of Mexico. In particular this bibliography covers the impacts of the DWH oil spill, mapping and restoration techniques for those coral communities. 

The National Oceanic and Atmospheric Administration Deep Sea Coral Research and Technology Program’s convened a 2-day science priorities workshop on April 16-17, 2018 at the University of California, Santa Barbara. The purpose of the workshop was to build partnerships and set research priorities for the Program’s 4-year West Coast Deep-Sea Coral Initiative (WCDSCI; 2018-2021).

Aphyonids are poorly-known, live-bearing brotulas (Ophidiiformes, Bythitidae) that until recently were considered to be in a distinct family, Aphyonidae. A single, ca. 9.3 cm total length aphyonid observed during a remotely-operated vehicle survey in the Mariana Archipelago at 2504.2 m on Explorer Ridge (20.68152°N, 145.08750°E) is the first seen alive in its natural habitat. Collection to verify its identification was not possible, but based on observations it was a species of either Barathronus or Nybelinella.

Mechanical failures forced many B-29s into the ocean surrounding Saipan and Tinian. Terrestrial wreckage of these aircraft has been located in the Pacific region, but no losses in deep water were located until 2016, when a NOAA exploration cruise investigated sonar targets in the Saipan Channel, between Saipan and Tinian. Disarticulated wreckage from a B-29 was located at 370 m over a large area of the seabed. Telepresence-enabled, non-invasive exploration from NOAA Ship Okeanos Explorer allowed scientists on shore to view live streaming video and to work collaboratively to guide the investigation.

This paper discusses and illustrates the 23 primnoid species collected by the R/V Okeanos Explorer in the US marine protected areas in the central and western Pacific, ranging from the Musician Seamounts in the north to American Samoa to the south, and the northern Mariana Islands to the west (CAPSTONE expeditions, 2015-2017). In situ photographs are provided for most species.

Telepresence-enabled exploration of deep sea environments has developed over the past 30 years, providing access to archaeologists, scientists, and the general public to sites otherwise inaccessible due to depth. Pioneered through the inception of the JASON Project in the late 1980 s, telepresence missions have expanded to two dedicated ships of exploration, NOAA Ship Okeanos Explorer and exploration vessel Nautilus, and has been implemented on a series of opportunistic missions on other vessels. This paper chronicles the history of the use of telepresence for the exploration of shipwrecks in deep water as well as how this capability has allowed the public to engage with such missions.

The family Callanthiidae contains two genera, Grammatonotus (with ten nominal and a few putative species) and Callanthias (the Splendid Perches, with seven species). We provide characters that distinguish callanthiids from other percoids and that distinguish Grammatonotus from Callanthias.

A large number of remotely operated vehicle surveys have been conducted in the Gulf of Mexico deep sea since 2008, including telepresence cruises that broadcast live seafloor images to shore. Visual observations from these surveys were collated and geo-referenced in a regional database with national museum records in order to: (1) map the distribution of L. glaberrima throughout the U.S. Gulf of Mexico, (2) predict the distribution of L. glaberrima based upon environmental correlates using maximum entropy (MaxEnt) modeling, and (3) correlate the size-class structure to the age-class structure using growth rate estimates from previous radiocarbon studies.

From 2010 to 2014, underwater camera surveys in the Aleutian Islands were completed with the objective of evaluating potential effects of substrate type, tidal currents, depth, and fishing pressure on distribution, abundance, diversity, and size of structure-forming invertebrate communities. The presence of rocky substrates was associated with higher probability of presence, higher density, and taller structure-forming invertebrates.
