This metadata record describes the benthic cover data of Aua Reef, American Samoa, produced from the benthic imagery analysis performed by the Ecosystem Sciences Division (ESD) of the Pacific Island Fisheries Science Center (PIFSC) and funded by the Coral Reef Conservation Program (CRCP). 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 as well as coral demography data are described and archived separately, see 'Related Items' below. 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 focal point of this project was to establish a biological and water quality and carbonate chemistry baseline for Aua reef. This work was aimed at identifying measurable spatial differences in the structure and composition of the benthic and coral community at Aua that can be explained by measurable spatial patterns of water quality (nutrients and sediments) and water carbonate chemistry (pH and Alkalinity). This work is of fundamental importance for the development of the Aua Watershed Management Plan, and will enable Federal and jurisdictional resource managers to more effectively assess the effectiveness of watershed management actions reducing land-based pollution and impacts to the adjacent coral reef ecosystems.

Benthic composition data sets derived from image analysis are highly reliable within the stipulated taxonomic context. 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, percent cover estimates for some sites may derive from differing number 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. Classification is completed to the functional group/genus level (Tier 1-Tier 3). Conceptual Consistency The same method of image analysis was used at each surveyed site. The methodology to analyze benthic imagery using CoralNet to derive benthic cover values. The data described here were derived from the analysis of benthic images collected along photoquadrat surveys by the NOAA Ecosystem Sciences Division (ESD): Still photographs were collected during belt transect surveys of coral demography to record the benthic community composition at predetermined points along the transect line with a high-resolution digital camera mounted on a pole. Photoquadrat surveys were conducted along one, 30 meter transect per site. Photos of the benthic substrate were taken at one meter intervals starting at meter 1, (30 images/transect; 30 images total). The benthic photoquadrat images were analyzed by using the web-based annotation tool CoralNet (Beijbom et al. 2016). CoralNet assigns 10 random points per photo and the benthic element falling directly underneath each point is identified to three functional group levels: Tier 1 (e.g. hard coral, macroalgae, etc.), Tier 2 (e.g. Hard coral by morphology = massive, branching, etc.), and Tier 3 (e.g. Hard coral by genus and morphology). The detailed list of each functional group level or tier is included in the benthic image analysis classification scheme. See the published standard operating procedures for further details.
