The benthic cover data described herein were generated by the NOAA Ecosystem Sciences Division (former Coral Reef Ecosystem Program, CREP) from the quantitative analysis of photoquadrat benthic images using the image analysis software CoralNet, whereby random points are projected on each image and the benthic elements falling directly underneath each point are identified. The images were collected at sites in Faga'alu Bay in 2015 and 2020 during belt transect surveys of coral demography. The data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive. The benthic images and coral demography data are described and archived separately.
These data are part of a NOAA Coral Reef Conservation Program (CRCP) funded project aimed at establishing baseline data for benthic cover and composition via Rapid Ecological Assessment (REA) surveys conducted by the NOAA Ecosystem Sciences Division (ESD) (formerly Coral Reef Ecosystem Program -CREP) at Faga'alu Bay, Tutuila, American Samoa between 2012 and 2020.
In August 2012 Faga'alu watershed in American Samoa was adopted by the U.S. Coral Reef Task Force Watershed Partnership Initiative as a priority site, with the objective to reduce inputs of land-based sources of pollution to nearby coastal areas and coral reefs within the watershed. The Samoa Maritime rock quarry was found to be a major contributor to the periodic flux of excessive sediments onto the adjacent reef in Faga'alu. In September of December 2014, mitigation actions were implemented at the Samoa Maritime Quarry, including the installation of drainage systems, alternative ground cover, and retention ponds.
Data were collected to assess the effectiveness of management actions to reduce land-based sources of pollution impacts undertaken at the Samoa Maritime rock quarry. Pre-intervention baseline data were collected in 2013 and subsequent post-intervention monitoring in 2015 and 2020. Funding provided by the NOAA Coral Reef Conservation Program (CRCP) through two internal projects entitled. 1) Comprehensive Baseline Assessment and Pilot Test of Outcome Performance Measures in Faga'alu Bay, American Samoa, awarded to Suzie Holst. 2) Status and Trends Assessment for Land-based Sources of Pollution Impacts on Benthic Reef Communities in Faga'alu Bay and Vatia Bay, American Samoa, awarded to the NOAA Ecosystem Sciences Division.

An Erosion and Sediment Control Plan was implemented at Samoa Maritime quarry to reduce excess sedimentation from quarry operations, and mitigation actions from the Plan took place in 2014 to install retention basins designed to stem the input of excess sediments into Faga'alu Stream below the quarry. REA surveys conducted by ESD in 2012 and 2013 serve as the pre-mitigation baseline, and surveys conducted in 2015 and 2020 document the downstream effects (e.g., changes to the coral community) in Faga'alu Bay from the mitigation efforts to reduce the sediment loads upstream.

Accuracy
Data sets derived from image analysis are highly reliable within the stipulated taxonomic context. Each time a production run is performed for a region a calibration exercise is conducted by all staff that will participate in that round of image analysis classification. Usually 100-150 photos are selected from the photos being processed as part of the production run series, or other region-relevant photo streams. Then, image analysis software assigns 10 random fixed points per photo. Each photo analyst is asked to classify the same set of points in each of the photos used as part of the calibration exercise. The goal of the calibration exercise is to assess inter-observer variability. Inter-observer variability rates are available upon request for each production run.
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 images (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 3).
Benthic images were collected during coral demographic surveys in 2012, 2015, and 2020 in Faga'alu; however, only the images collected during the most recent surveys in 2015 and 2020 were analyzed.
Conceptual Consistency
The same method of image analysis was used at each surveyed site.
The data described here were derived from the analysis of benthic images collected along photo-quadrat surveys by the NOAA Ecosystem Sciences Division (ESD):
In 2015 photo quadrat images were taken every meter from the 1-m to the 15-m mark along TWO, 18-m transects per site (n = 30 images).
In 2020 photo quadrat images were taken every meter from the 1-m to the 30-m mark along one 30-m transect line (n = 30 images).
Still photographs were collected during belt transect surveys of coral demography to record the benthic community composition at predetermined points along the transect lines with a high-resolution digital camera mounted on a pole. 30 photoquadrat images were collected at each site.
In 2015 the photoquadrat surveys were conducted along two, independent 18 meter transects per site. Photos of the benthic substrate were taken at one meter intervals starting at meter 1, along the left hand side of each 18 meter transect (15 images/transect; 30 images total)
In 2020 the 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, along the left hand side of the transect (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 elements 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.
