    • National Coral Reef Monitoring Program: Benthic cover derived from analysis of images collected from climate stations across American Samoa

    Metadata Updated: November 1, 2023

    The benthic cover data in this collection result from the analysis of images produced during benthic photo-quadrat surveys conducted along transects at climate stations and permanent sites across American Samoa. These sites were identified by the Ocean and Climate Change team and the ongoing National Coral Reef Monitoring Program. Benthic habitat imagery were quantitatively analyzed using a web-based annotation tool called CoralNet (Beijbom et al. 2015). In general, images are analyzed to produce 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.). The imagery analyzed in order to produce the benthic cover data is also included in this collection.
