Benthic imagery was collected at 18 randomly-selected sites during coral demographic surveys by the NOAA ESD during the 2022 fly-in mission to American Samoa (MP2206). After processing and sorting site photos, imagery was qualitatively analyzed using the web-based CoralNet image annotation tool. CoralNet projects random points on each image, and the benthic elements falling directly underneath each point are identified by trained scientists. The source imagery analyzed to produce benthic cover estimates are archived separately with the NOAA National Centers for Environmental Information (NCEI) in NCEI Accession 0270551. Data from benthic surveys of Aua Reef establishes a comprehensive biological baseline for land-based sources of pollution impacts on benthic composition and coral demography. These efforts feed into the higher-level CRCP objectives by establishing an in-situ tracking system to assess the effects of management and mitigation strategies and activities in the target watersheds to reduce land-based sources of pollution impacts on coral reefs.

The robot tool annotates ten random points on each image for a total of 300 points per site, which are then reviewed by human analysts. The human annotations are then used to train the robot. This data is the final form of the robot-assisted human annotations. Taxa identification occurs at three functional group levels of benthic cover. Tier 1 (e.g., hard coral, soft coral, macroalgae, turf algae, etc.), Tier 2 (e.g., Hard Coral = massive, branching, foliose, encrusting, etc.; Macroalgae = upright macroalgae, encrusting macroalgae, bluegreen macroalgae, and Halimeda, etc.), and Tier 3 (e.g., Hard Coral = Astreopora sp, Favia sp, Pocillopora, etc.; Macroalgae = Caulerpa sp, Dictyosphaeria sp, Padina sp, etc.); Data Quality Method: ACCURACY: 1) Each analyst is required to complete training and a calibration exercise prior to image analysis (classification/annotation), and follows the Benthic Image Analysis Standard Operating Procedure (Lozada-Misa et al. 2017). For a calibration exercise, a subset of photos (~100-150) are selected from the production series and CoralNet assigns 10 random fixed points per photo. Each analyst classifies the same set of points for each of the photos used in the calibration exercise. The goal of the calibration exercise is to assess inter-observer variability. 2) Handheld GPS units were used to locate random sites and mark site locations. COMPLETENESS REPORT: The data set derived from the image analysis is as good as the images themselves; poor images with low contrast, inappropriate white balance, or out of focus may have to be discarded. Therefore, benthic estimates for some sites may derive from differing numbers of points between sites. Although the analysis process is statistically robust to allow for differing n (points) between sites, users should be aware of this limitation. asNeeded Metadata are developed, maintained and distributed by NCEI. Updates are performed as needed to maintain currentness.
