Diver-Based Structure-from-Motion imagery from coral reef restoration surveys in the Lower Florida Keys: July 2022 and July 2023

During the summers of 2022 and 2023, U.S. Geological Survey (USGS) researchers conducted underwater surveys aimed at quantifying the impact that past coral restoration by Mote Marine Laboratory had on the reef-accretion process. The surveys were conducted along paired transects representing restored and non-restored areas of eight offshore reefs and three patch-reef sites in the Lower Florida Keys. At each location on each reef, USGS researchers collected images (39,480 images in total) that were used to ...

August - October 1998 Faunal Survey in Closed Area II, Central Georges Bank

During the months of August-October, 1998, the National Marine Fisheries Service and the New England scallop industry conducted a cooperative survey of Closed Area II to assess the sea scallop population after 3.5 years of closure to all fishing. The area was closed in December 1994 to conserve fish stocks. Most of the tows are concentrated in the southern part of Closed Area II (south of 41o 30'N) and in the northernmost part (north of 41d 50'N). The central area between 41d 30' and 41d 50'N was sparsely ...

Fish and epibenthic invertibrates from Albatross IV otter trawl survey, June 1999

The NMFS/USGS survey of the southern part of Closed Area II was conducted in June, 1999 on 2 cruises: NMFS Albatross cruise ALB9905, June 2-9 (this cruise is also designated as USGS ALBA9933); and USGS R/V Connecticut cruise CONN9912, June 23. Study sites (1A, 2A, MMS1/2D, etc.) are part of a pre-determined grid of sites designed to sample the southern part of Closed Area II (south of 40o 30'N) and the area around its margins open to fishing that lies within approximately 2 nm of the western, southern, and ...

Water column temperature and salinity, Albatross IV survey, June, 1999

The NMFS/USGS survey of the southern part of Closed Area II was conducted in June, 1999 on 2 cruises: NMFS Albatross cruise ALB9905, June 2-9 (this cruise is also designated as USGS ALBA9933); and USGS R/V Connecticut cruise CONN9912, June 23. See the location map for the 1999 survey. For an overview of sampling strategy and methods for both cruises, see the cruise report file for Albatross cruise ALB9905 (ca21999alb9905rept.pdf). Study sites (1A, 2A, MMS1/2D, etc.) are part of a pre-determined grid of ...

Still-image frame grabs and benthic habitat interpretation of underwater video footage, March 2014, Faga`alu Bay, American Samoa

Underwater video was collected in March 2014 in the nearshore waters of Faga`alu Bay on the island of Tutuila, American Samoa, as part of the U.S. Geological Survey Coastal and Marine Geology Program's Pacific Coral Reefs Project. This dataset includes 2,119 still images extracted from the video footage every 10 seconds and an Environmental Systems Research Institute (ESRI) shapefile of individual still-image locations with benthic habitat interpretations for each image.
