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

Supplemental Information | Accessions 0159170, 0157753, 0187561, 0240353, 0289892. Climate stations are 3-4 sites per island that are selected in a stratified random fashion to be roughly equally spaced around the island, along the 15 m contour, on hard bottom, and at least 1 km away from a river mouth or embayment. Once selected, multiple features of the coral reef environment are assessed, including in-situ temperature (STR), seawater carbonate, net carbonate accretion (CAU), bioerosion (BMU), and cryptobiota diversity (ARMS). These data are archived separately. |
Purpose | The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP is intended to coordinate various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA will be able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. |
