NCCOS Assessment: Underwater Video and Photographs for Ground Validation and Accuracy Assessment of Benthic Habitat Maps of Saipan Lagoon, Commonwealth of the Northern Mariana Islands, 2016-07-28 to 2016-08-09

Published by National Centers for Coastal Ocean Science | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 05:13 PM | Dataset Last Updated: March 20, 2017 at 12:00 AM
Underwater video and photographs were acquired between 28 July 2016 and 9 August 2016 at nearly 600 sites throughout the lagoon to document the presence and percent-cover of benthic substrate and cover types. Two sets of independent data were collected, one for Ground Validation (n = 292) and the other for Accuracy Assessment (n = 273). Abundances for five substrate and seven cover types were estimated to the nearest 10% in real time. These presence/absence data were used to create and evaluate the accuracy of the habitat predictions and map in Saipan Lagoon. For complete descriptions of these datasets and the methods used to generate them, please see: Kendall et al. (2017).

    "description": "CNMI's Bureau of Environmental and Coastal Quality (BECQ) and NOAA's Pacific Islands Regional Office (PIRO) partnered with NOAA's National Centers for Coastal Ocean Science (NCCOS) to develop updated habitat maps and assess habitat changes in Saipan Lagoon,CNMI. NCCOS developed these spatially resolved maps using environmental predictors, underwater videos/photos and mathematical modeling techniques. The new maps were designed to inform the Saipan Lagoon Use Management Plan (SLUMP), which is being updated in response to changes in lagoon habitats, user activities, and increases in tourism. Understanding the present spatial distribution of benthic habitats is an important part of the Territorial Government's process to evaluate zoning scenarios, minimize user conflicts, ensure public safety, and prevent environmental degradation inside the lagoon. Products from this assessment may also support coastal and ocean management efforts by other territorial and federal agencies working in Saipan. This work was funded by NOAA Coral Reef Conservation Program (CRCP Project #31100).",
