Guam and CNMI Underwater Photomosaics

Description

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.

0 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. https://doi.org/10.25921/wg96-cq17
