NOAA National Centers for Environmental Information. Dataset. https://doi.org/10.25921/m0f6-3b26. This data package contains information and maps showing the geology and biology of select submerged lands (0 to 40 meters deep) offshore of western Saipan, Commonwealth of the Northern Mariana Islands (CNMI). This information and maps were developed using benthic information from underwater photographs, environmental predictor variables derived from satellite imagery and bathymetry, and machine learning modeling approaches. download https://doi.org/10.25921/wg96-cq17 WWW:LINK-1.0-http--link GIS datasets for Guam This data package contains information and maps showing the geology and biology of select submerged lands (0 to 50 meters deep) around Navy Base Guam (NBG) and Haputo Ecological Reserve Area (ERA) Guam, Mariana Islands. This information and maps were developed using benthic information from underwater photographs, environmental predictor variables derived from satellite imagery and bathymetry, and machine learning modeling approaches. download This data package contains georeferenced underwater photomosaics for more than 600 sites in 0 to 50 meter depths around the islands of Guam and Saipan. The photographs used to create these photomosaics were acquired from August 2021 to May 2022 using digital single-lens reflex camera (DSLR) cameras. Green lasers provided a measurement scale (10 cm). A Trimble GeoXH GPS provided the location of the vessel, and a Blueprint SeaTrac ultra short baseline (USBL) X150 beacon and X010 transponder provided the location and depth (XYZ) of the drop camera. The photographs were georeferenced (i.e., given a latitude and longitude), and mosaicked using a custom Python script (Pierce and Winians, 2023; performed using Agisoft Metashape application programming interface). The field work in Saipan was funded by NOAA National Centers for Coastal Ocean Science (NCCOS) and the NOAA Coral Reef Conservation Program (CRCP). The field work in Guam was funded by the Naval Facilities Engineering Command Marianas (NAVFAC Marianas). Both efforts were conducted in partnership with and in consultation with local partners and the territorial governments. The purpose of this field work was to collect underwater photographs of the seafloor to train and validate benthic habitat models and maps. From these photographs, analysts identified five to seven substrate and 12 to 14 biological cover types. Percent cover was estimated to the nearest 1% for each habitat type. The amount of annotated area (four square meters) was standardized in each photograph so that it matched the spatial resolution (i.e., two x two meter pixels) of the environmental predictors. Multiple substrate and cover types were often present at each site. Percent covers were also converted to presences (1) and absences (0). This information was then used to train and validate benthic habitat models and maps for select areas offshore Guam and Saipan in 0 to 50 meter depths. These areas were selected by local management agencies because they include ecologically and economically valuable shallow-water coral reefs. The resulting maps will be used by local management agencies to mitigate impacts to, and restore, these important marine resources. Funding was provided to acquire these datasets by NOAA NCCOS, NAVFAC Marianas and NOAA CRCP. completed NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0291792 NA jpg https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0292018 NA jpg EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > REEF > CORAL REEF EARTH SCIENCE > OCEANS > COASTAL PROCESSES > CORAL REEFS theme Global Change Master Directory (GCMD) Science Keywords 17.0 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA OCEAN > PACIFIC OCEAN > WESTERN PACIFIC OCEAN > MICRONESIA > GUAM OCEAN > PACIFIC OCEAN > WESTERN PACIFIC OCEAN > MICRONESIA > NORTHERN MARIANA ISLANDS VERTICAL LOCATION > SEA FLOOR place Global Change Master Directory (GCMD) Location Keywords 20.8 1 meter - < 10 meters dataResolution Global Change Master Directory (GCMD) Vertical Data Resolution Keywords 10.3 ACOUSTIC RECEIVERS ACOUSTIC SOUNDERS GPS > Global Positioning System HRC > High Resolution Camera instrument Global Change Master Directory (GCMD) Instrument Keywords 17.2 Geographic Information > Marine Management Areas Numeric Data Sets > Benthic theme CoRIS Discovery Thesaurus COUNTRY/TERRITORY > Northern Mariana Islands > Saipan > Saipan Island (15N145E0002) COUNTRY/TERRITORY > United States of America > Guam > Apra Harbour (13N144E0051) COUNTRY/TERRITORY > United States of America > Guam > Guam (13N144E0000) COUNTRY/TERRITORY > United States of America > Guam > Haputo (13N144E0006) OCEAN BASIN > Pacific Ocean > Western Pacific Ocean > Saipan Island > Chalan Kanoa (15N145E0012) OCEAN BASIN > Pacific Ocean > Western Pacific Ocean > Saipan Island > Saipan Island (15N145E0002) theme CoRIS Place Ocean/Seas Keywords EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > GIS EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Mapping > Habitat Mapping EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Photographic Analysis EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs EARTH SCIENCE > Oceans > Coastal Processes > Coral Reefs > Coral Reef Ecology > Habitats theme CoRIS Theme Thesaurus NCCOS Research Data Type > Field Observation NCCOS Research Data Type > Geospatial NCCOS Research Priority > Marine Spatial Ecology NCCOS Research Topic > Habitat Mapping NCCOS Research Location > Region > International NCCOS Research Location > Region > Pacific Ocean NCCOS Research Location > U.S. States and Territories > Mariana Islands > Guam NCCOS Research Location > U.S. States and Territories > Mariana Islands > Saipan theme NCCOS Discovery Keywords HABITAT - BENTHIC theme NODC Data Types NOAA Coral Reef Conservation Program Naval Facilities Engineering Command (NAVFAC) Marianas theme Project COUNTRY/TERRITORY > Northern Mariana Islands > Saipan > Chalan Kanoa (15N145E0012) place CoRIS Place Country/Territory Keywords COUNTRY/TERRITORY > Northern Mariana Islands > Saipan > Saipan Island (15N145E0002) COUNTRY/TERRITORY > United States of America > Guam > Apra Harbour (13N144E0051) COUNTRY/TERRITORY > United States of America > Guam > Guam (13N144E0000) COUNTRY/TERRITORY > United States of America > Guam > Haputo (13N144E0006) place CoRIS Place Thesaurus VERTICAL LOCATION > SEA FLOOR stratum Global Change Master Directory (GCMD) Stratum Keywords Blueprint SeaTrac ultra short baseline (USBL) X150 beacon instrument ACOUSTIC RECEIVERS Blueprint SeaTrac ultra short baseline (USBL) X010 transponder instrument ACOUSTIC SOUNDERS Trimble GeoXH GPS instrument GPS > Global Positioning System Nikon D7500 DSLR camera Sony alpha7 IV DSLR camera instrument HRC > High Resolution Camera DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Completeness Report Completeness Commission: The data is programmatically and visually inspected for completeness. | Conceptual Consistency All formatted data cover the entire area specified for this project and were validated using a combination of commercial processing software and GIS software to ensure proper formatting and loading prior to delivery. This data was collected by NOAA National Centers for Coastal and Ocean Science (NCCOS). The photographs and positioning information were acquired from August 20, 2021 to May 12, 2022. The photographs were acquired using Nikon D7500 camera in 2021 and a Sony alpha7 IV mirrorless camera in 2022). Green lasers provided a measurement scale (10 cm). A Trimble GeoXH GPS recorded the location of the vessel, and a Blueprint SeaTrac ultra short baseline (USBL) X150 beacon and X010 transponder recorded the location and depth (XYZ) of the cameras. The resulting photographs were georeferenced (i.e., given a latitude and longitude), and mosaicked to produce photomosaic and 3D model of the seafloor using a custom Python script (Pierce and Winians, 2023; performed using Agisoft Metashape application programming interface). The photographs and positioning information were acquired at approximately 668 sites from August 20, 2021 to May 12, 2022. A minimum of 4 square meters of the seafloor was photographed at each site. The process for collecting these overlapping, underwater photographs was identical at each site. A handheld Garmin GPS 76 unit was used to navigate to each site via a small boat. A drop camera system was then lowered to within 1.5 to 2 meters of the seafloor. This drop camera system included: (1) a downward-looking digital single-lens reflex (DSLR) camera (i.e., a Nikon D7500 camera in 2021 and a Sony alpha7 IV mirrorless camera in 2022), (2) two green lasers spaced 10 cm apart, and (3) a Blueprint Subsea SeaTrac ultra-short baseline (USBL) X150 beacon and X010 transponder. In 2022, an oblique-looking GoPro HERO10 Black in a Spot X Squid housing was also included, which provided real-time video topside for situational awareness. The downward-looking DSLR cameras collected still photographs of the seafloor every 0.5 to 1 s. The camera settings included: focal lengths = 18 mm, white balance = auto, and shutter speed = 1/200 s. Both jpeg and .RAW files were recorded. The photographs overlapped by 60 to 80%. The lasers provided a measurement scale (10 cm) and were visible in some but not all of the photographs. The USBL transponder provided the location and depth (XYZ) of the drop camera every 5 s, and a Trimble GeoXH GPS provided the location of the vessel every 1 s. The Trimble GPS antenna was positioned directly over the USBL transmitter pole to minimize lever arm offsets. For more information, see: Costa, B., and Sweeney, E. (2024).

Characterizing benthic habitats of western Saipan, CNMI. NOAA Technical Memorandum NOS NCCOS 328. https://doi.org/10.25923/psjm-h924 NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov processor Underwater photographs were visually reviewed for quality and color corrected (performed using Adobe Lightroom software). The GPS data were differentially corrected using a Continuously Operating Reference Station on Guam and reprojected to the WGS 1984 UTM 55 North coordinate system (performed using GPS Pathfinder Office software). The USBL data were exported from SeaTrac PinPoint software and matched with the corrected GPS locations using timestamps. Underwater photographs were georeferenced using these GPSUSBL locations (ESRI, 2023; performed using ArcGIS Pro, Geotagged Photos To Points function). Not all images were georeferenced because sampling frequencies differed among the USBL (approximately 5 s), GPS (approximately 1 s), and cameras (approximately 0.5 to 1 sec). To georeference the remaining photographs, a custom Python script was created to interpolate positions between the GPS-USBL locations. This script also mosaicked and developed 3D models from the resulting georeferenced photographs (Pierce and Winians, 2023; performed using Agisoft Metashape application programming interface).

NOAA Technical Memorandum NOS NCCOS 328. https://doi.org/10.25923/psjm-h924 National Centers for Coastal Ocean Science processor Five to seven substrate and 12 to 14 biological cover types were identified visually in the above georeferenced photographs. The amount of annotated area (four meters squared) was standardized in each photograph so that it matched the spatial resolution (i.e., two x two meter pixels) of the environmental predictors. Multiple substrate and cover types were often present at each site. Percent cover was estimated to the nearest 1% for each habitat type. Percent covers were also converted to presences (1) and absences (0) and used to train or validate the habitat predictions. In Saipan, n =1,109 annotations, where 617 annotations were used for model training and 492 annotations were used for model validation. In Guam, n = 674 annotations, where 346 annotations were used for model training and 328 annotations were used for model validation. For more information, see: Costa, B., and Sweeney, E. (2024).
