Title: Coral reef ecosystem marine protected area monitoring in Fagamalo, American Samoa: benthic percent cover derived from analysis of benthic images collected during belt transect surveys of coral demography in 2015
Short Name: Fagamalo: Benthic Cover
Status: Completed
Publication Date: 2017
Abstract:

In 2010 the village of Fagamalo, Tutuila, American Samoa, designated a no-take Marine Protected Area that sees the protection of 2.25 square kilometers of ocean. Because little is known regarding the status of living marine communities in the area, and at the request of the American Samoa Department of Marine and Wildlife Resources, NOAA scientists conducted surveys to assess the status of the benthic communities and establish a baseline against which to compare temporal change.

The benthic cover data described here were generated from the quantitative analysis of photoquadrat benthic images using image analysis software, whereby random points are projected on each image and the benthic elements falling directly underneath each point are identified. The images were collected at 18 randomly selected stratified sites in Fagamalo in 2015 during belt transect surveys of coral demography by the NOAA Coral Reef Ecosystem Program (CREP).

The benthic cover 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.

Purpose:

These data were generated from benthic surveys to establish a comprehensive baseline for benthic composition and coral demographics, and are part of a NOAA Coral Reef Conservation Program (CRCP) funded project, entitled: "Coral reef ecosystem monitoring training and capacity building to support improved resource management in American Samoa."

NOAA Coral Reef Ecosystem Program (CREP) Data Sharing Recommendations, version 9.0 updated August 12, 2015:

CREP welcomes the opportunity to collaborate on research issues contributing to the scientific basis for better management of marine ecosystems. CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols.

The following recommendations are for your consideration as you use this data:

1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators.

2) In all presentations, product releases, or publications using data generated by CREP, proper acknowledgement of both CREP and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below.

3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections.

4) Those receiving data are strongly urged to inform the CREP Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided.

Data Quality

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 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).

Conceptual Consistency:

The same method of image analysis was used at each surveyed site.

Quality Control Procedures Employed:

Quality control is enforced by means of point-to-point, inter-observer calibration exercises that are conducted before each image analysis production series. Training modules and standard operating procedures have also been developed and documented to ensure improved performance and consistent imagery analysis results produced by multiple analysts.

Process Steps

Process Step 1

CC ID: 308975
Description:

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. The photoquadrat surveys were conducted along two, independent 18 meter transects. 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; Rep A and B).

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.
