Abstract

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).

    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).

Purpose:

Ground Validation (GV) data are the basis for correlating observed substrate and cover types with their associated values in the predictor datasets. Ultimately, the data are used to train and optimize mathematical models that predict habitats throughout the lagoon. Accuracy Assessment (AA) data are used to independently evaluate the performance and accuracy of predictive models and the composite habitat map.

Process Steps

Process Step 1

CC ID: 758991
Description:

Locations of the GV sites were selected manually to include the full range of habitats, depths, and environmental settings found in the lagoon. AA sites were chosen by randomly scattering points in nine habitat types.

The process for collecting both the GV and AA data was identical at each field site. Sites were typically accessed via small boat, kayak, or wading. At each site, two Go Pro HERO4 Black cameras were deployed on an aluminum pole for sites <9 m deep and on a rope with a rotating camera system for deeper sites. On both deployment systems, a downward facing camera was fixed at 1 meter above the bottom to standardize the field of view to encompass ~ 1 m2 of seafloor, and an oblique facing camera captured surrounding habitats. Once the cameras were deployed, our precise location was recorded every five seconds using a GPS receiver. Abundances for the five substrate and seven cover types were estimated to the nearest 10% in real time. GPS data were post-processed and differentially corrected. Average positions were calculated for each site, and all underwater videos and photos were reviewed for quality control. Substrate and cover abundances were converted to presences (1) and absences (0).
