Surveys were conducted by the NOAA Fisheries, Ecosystem Sciences Division (ESD) from September 24 to October 3, 2018 at Pearl and Hermes Atoll during an ESD-led marine debris mission to the Northwestern Hawaiian Islands (NWHI) aboard the NOAA Ship Oscar Elton Sette. The lagoon at Pearl and Hermes was surveyed equally across the spatial gradient, from locations where derelict fishing nets are common to locations where derelict fishing nets have never been observed. During the 2018 mission, only a subset of marine debris surveys resulted in a SfM survey. Fishing nets were located during swim surveys and selected for SfM if the net was interacting with coral or hard substrate, the depth of the net was within ~1–4 m of the surface, and the area of the net fit within the 9 sq. meter SFM survey plot. A complete SfM survey is comprised of three sets of images. Two sets were taken at each net-impact site, one series “before” and one series “after” the fishing net was removed from the reef. A final set was taken at a paired “control” site that was selected ≥50 m away from the net-impact site. During a SFM survey, a permanent 3 x 3 m plot was established around the center of the fishing net, and the survey plot was photographed using a back and forth swim pattern (“before” photos) for later processing using a SfM approach. The fishing net was then removed and the same area was photographed again in the same way (“after” photos). The paired control site was also photographed using the same method (“control” photos). The Papahānaumokuākea Marine National Monument (PMNM) includes the 1200 nautical mile chain of atolls and islets known as the Northwestern Hawaiian Islands (NWHI) that are geographically positioned as a repository for marine debris. Marine debris circulates within the North Pacific Subtropical Gyre until it encounters the atolls of the NWHI. The Ecosystem Sciences Division (ESD) at NOAA Fisheries has conducted both ship- and shore-based missions in the NWHI to survey for and remove derelict fishing gear and many other types of marine debris. Exploratory and opportunistic efforts began in 1996 that evolved into ~annual cruises. The collected photographs were processed using a structure from motion (SfM) approach to create orthophotos and analyzed in GIS for benthic cover. The purpose of the Structure from Motion (SfM) surveys at Pearl and Hermes Atoll is to understand whether derelict fishing nets significantly alter the benthic community composition of the reef. In addition, we investigated how net size and fouling level may vary the severity of this impact. This study leveraged SfM, an emerging photogrammetry technique, to allow efficient data collection alongside marine debris survey and removal efforts. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:PIFSC-SfM-Images-HI Preview graphic PNG 0210740 0210811 0210812 NCEI ACCESSION NUMBER 2020-06-10 publication images theme NODC DATA TYPES THESAURUS camera instrument NODC INSTRUMENT TYPES THESAURUS benthic biological imagery in situ theme NODC OBSERVATION TYPES THESAURUS NOAA Ship Oscar Elton Sette platform NODC PLATFORM NAMES THESAURUS Coral Reef Ecosystem Program dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Pacific Islands Fisheries Science Center dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS CORAL REEF STUDIES project NODC PROJECT NAMES THESAURUS North Pacific Ocean Papahānaumokuākea Marine National Monument place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NMFS > National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
