Data and information collected by the submersible Johnson Sea-Link II along its track during seventeen dives of the 2003 "Life on the Edge: Exploring Deep Ocean Habitats" expedition sponsored by the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration, August 16 through August 27, 2003. Measurements and information include sub's position, altitude, and depth; personnel assignments; dive, mission, and vehicle ID's; and sound velocity measurements. The Marine Operations Division of the Harbor Branch Oceanographic Institution provided the original submersible data.

Three months after the Deepwater Horizon (DWH) oil spill, and before extensive oil impacts reach shelf-edge reefs in the eastern Gulf of Mexico, NOAA's Cooperative Institute for Ocean Exploration, Research and Technology (CIOERT) is conducting a rapid response, multi-disciplinary, multi-institutional expedition to assess the impacts of the DWH oil spill on Florida's esophotic and deepwater ecosystems. CIOERT's expertise, tools, and technologies will address critical research needs associated with the DWH oil spill and potential impacts on the health of diverse ecosystems off Florida's Gulf and Atlantic coasts. CIOERT's 2010-11 Science Plan, developed before the spill began in April 2010, included a multi-disciplinary science expedition to study deep coral and live bottom reefs along the shelf edge of Florida, from the Cape Canaveral to the Alabama border. In response to the spill event, the mission has been moved up to begin July 9 aboard FAU/HBOI's R/V Seward Johnson. Scientists will use the research submersible Johnson-Sea-Link (JSL) to address critical research needs associated with the Deepwater Horizon oil spill and the potential impacts on the health of diverse shelf-edge ecosystems and new ocean resources. Working closely with technicians trained in Natural Resource Damage Assessment (NRDA) protocols, the expedition will characterize sub-surface spill properties and identify impacts on deep-reef resources. The expedition is closely integrated with other NOAA missions, complementing them in information collected and areas sampled.

This expedition is the first of three cruises for the Deep SEARCH project focused on exploring and characterizing seeps, corals, and canyon environments along the Atlantic margin.

From August 6 - September 2, 2022 (Horta, Faial, Azores to San Juan, Puerto Rico) NOAA Ocean Exploration completed the Voyage to the Ridge 3 expedition (EX-22-06), a combined mapping and remotely operated vehicle (ROV) expedition to the Mid-Atlantic Ridge and Azores Plateau, Mid-Atlantic Ridge, and U.S. waters in the vicinity of Puerto Rico and the U.S. Virgin Islands. Operations during this 28-day expedition included the completion of 9 successful ROV exploration dives in the vicinity of the Azores, the Mid-Atlantic Ridge south of the Azores, and Puerto Rico. ROV dives were conducted in water depths ranging from 250 m to 6000 m for a total of 41 hours of bottom time. EX-22-06 also collected 56,769 square kilometers of seafloor bathymetry and associated water column data using an EM304 multibeam sonar. All data associated with this expedition have been archived and are publicly available through the NOAA Archives.

Pulley Ridge is a series of drowned barrier islands that extends almost 200 km in 60-100 m water depths. This drowned ridge is located on the Florida Platform in the southeastern Gulf of Mexico about 250 km west of Cape Sable, Florida. This barrier island chain formed during the initial stage of the Holocene marine transgression. These islands were then submerged and left abandoned near the outer edge of the Florida Platform. The southern portion of Pulley Ridge hosts zooxanthellate scleractinian corals, green, red and brown macro algae, and a mix of deep and typically shallow-water tropical fishes. This reef community is in unusually deep water, and its extent and the controls on its distribution were unknown. To address these questions scientists from the U.S. Geological Survey Coastal and Marine Geology Program in cooperation with scientists from the University of South Florida Department of Marine Sciences have completed a detailed mapping of the southernmost 35 km of Pulley Ridge. The area was mapped using multibeam bathymetry, sidescan-sonar imagery, and high-resolution seismic-reflection profiling to define the geologic framework on which the reef is established. Submersible dives, remotely operated vehicle (ROV) transects, and transects of bottom photographs and video were collected to identify the corals and to map their distribution. This extensive suite of data has been compiled and preliminary analysis of the data suggests that the reefs are not tied to the ridge system, but instead are more broadly distributed. Whether reef distribution is controlled by oceanographic conditions or by subtle differences in the substrate that overlies the barrier island system is unclear, and are topics of continued research.

This dataset contains oceanographic data (ADCP, CTD, ROV, Jason, Lander, SCS, Vehicle, XBT), images, and documentation. The primary goals of this cruise were as follows: Exploration of new sites and new areas within known sites, sampling of corals and associated fauna for biodiversity and biogeography, community sampling at seep and coral habitats, sediment sampling at soft sediment sites for biogeochemistry and diversity, collections of corals for live coral experiments, water sampling for water chemistry and microbial diversity, sediment, water, and faunal samples for eDNA work, geological observations and sampling for geomorphology, and lander deployments.

From July 9-30, 2022 (Norfolk, VA to Horta, Faial, Azores) NOAA Ocean Exploration completed the Voyage to the Ridge 2 expedition (EX-22-05), a combined mapping and remotely operated vehicle (ROV) expedition to the Mid-Atlantic Ridge and Azores Plateau. Operations during this 22-days at sea expedition included the completion of 10 successful ROV exploration dives in the vicinity the Azores and the Mid-Atlantic Ridge north of the Azores. ROV dives were conducted in water depths ranging from 420 m to 3350 m for a total of almost 53 hours of bottom time. EX-22-05 also collected 49,080 square kilometers of seafloor bathymetry and associated water column data using an EM304 multibeam sonar.
