National Coral Reef Monitoring Program: Benthic cover derived from analysis of benthic images collected from climate stations across the Hawaiian Archipelago from 2019-04-26 to 2019-09-04 (NCEI Accession 0240338)
The data described here result from benthic photo-quadrat surveys conducted along transects at climate stations and permanent sites identified by the Ocean and Climate Change team across the Hawaiian archipelago in 2019. 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.).
Climate stations are 3-4 sites per island that were 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 we assess multiple features of the coral reef environment including in-situ temperature (STR), seawater carbonate, net carbonate accretion (CAU), and bioerosion (BMU): all of which 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. To support a long-term Coral Reef Conservation Program for sustainable management and conservation of coral reef ecosystems and the NOAA Ocean Acidification Program (OAP), total alkalinity and dissolved inorganic carbon are measured to calculate various inorganic carbon system parameters that influence coral reef ecosystems monitored by the NOAA Coral Reef Ecosystem Program (CREP). SCUBA divers take discrete water samples at the benthos and at the surface at forereef study sites established by the ongoing Pacific Reef Assessment and Monitoring Program (RAMP). |
