DMP Template v2.0.1 (2015-01-01)
Please provide the following information, and submit to the NOAA DM Plan Repository.Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.
1. General Description of Data to be Managed
The coral reef benthic community data described here result from the annotation (classification) of benthic images collected during photoquadrat surveys conducted by the NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD, formerly the Coral Reef Ecosystem Division) as part of NOAA's ongoing National Coral Reef Monitoring Program (NCRMP). The photoquadrat surveys were conducted at coral reef sites according to protocols established by ESD and NCRMP during ESD-led NCRMP missions to American Samoa in 2015, 2018, and 2023.
SCUBA divers conducted benthic photoquadrat surveys at permanent sites established in coral reef habitats by ESD. A select number of these sites were chosen in hard-bottom habitat at ~15-m depths, and a subset of the permanent sites (climate stations) were established at north, south, east, and west points around each of the islands and atolls. The divers estimated and delineated each sites rectangular perimeter by temporarily placing measuring tapes with 1-m markers starting from a permanently installed reference stake on the reef. Along the nearshore 10-m side of the survey site and the downslope 5-m side, the measuring tapes marked every meter of the L-shaped 15-m transect used for photoquadrat documentation. The divers photographed the reef at 1-m intervals on both sides of the 15-m tape, generating 30 photographs per survey site.
The benthic habitat images were quantitatively analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill, 2006) software from 2010-2014 and the web-based annotation tool, CoralNet (Beijbom et al. 2015), from 2015 to present. Ten points were randomly overlaid on each image and human analysts identified the organism or type of substrate beneath, with 300 annotations (points) generated per site. Benthic elements falling under each point were identified to genus/morphology for hard corals, and to genus/functional group for algae, invertebrates, and other taxa following Lozada-Misa et al. (2017). In general, the analysis resulted in three levels of benthic community data, including taxa group Tier 1 (e.g., coral, soft coral, macroalgae, turf algae, etc.), Tier 2 (e.g., Coral = massive hard coral, branching hard coral, foliose hard coral, encrusting hard coral, etc.; Macroalga = upright macroalgae), and Tier 3 (e.g., Coral = Astreopora sp, Favia sp, Pocillopora, etc.; Macroalgae = Caulerpa sp, Dictyosphaeria sp, Padina sp, etc.). If Tier 3 resolution is not possible, the next finest resolution is used.. These benthic data can ultimately be used to produce estimates of relative abundance (percentage of benthic cover), frequency of occurrence, benthic community taxonomic composition, and relative generic richness.
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), bioerosion (BMU), and cryptobiota diversity (ARMS).
These data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive.

Lineage Statement:
Benthic photographs were collected during photoquadrat surveys conducted at permanent sites and climate stations in coral reef habitats by the PIFSC Ecosystem Sciences Division. The imagery was later analyzed using Coral Point Count with Excel Extentions (CPCe; 2014 and prior) or CoralNet (starting in 2015) to generate benthic community data.
Process Steps:
- SCUBA divers conduct benthic photoquadrat surveys at permanent sites established in hard-bottom habitat at ~15-m depths. A subset of the permanent sites (climate stations) were established at north, south, east, and west points around the island/atoll. The divers estimate and delineate each site’s rectangular perimeter by temporarily placing measuring tapes with 1-m markers starting from a permanently installed reference stake on the reef. Along the nearshore 10-m side of the survey site and the downslope 5-m side, the measuring tapes mark every meter of the L-shaped 15-m transect used for photoquadrat documentation. Divers photograph the reef at 1-m intervals on both sides of the 15-m tape, generating 30 photographs per survey site. Photoquadrat images are organized by site, color-corrected (if necessary), and quality controlled to remove non-photoquadrat/poor quality images. An optical validation script is used to re-name photos and enforce several validation checks.
- Benthic habitat images collected during photoquadrat surveys at permanent sites and climate stations (30 images per site) were quantitatively analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill 2006) software through 2014 or by using the web-based annotation tool CoralNet (Beijbom et al. 2015) from 2015 to present. Ten points were randomly overlaid on each image by CPCe or CoralNet and human analysts identified the organism or type of substrate beneath, with 300 annotations (points) generated per site. Benthic elements falling under each point were identified to genus/morphology for hard corals, and to genus/functional group for algae, invertebrates, and other taxa following Lozada-Misa et al. (2017). The analysis resulted in three levels of benthic community data, including taxa group (Tier 1: hard coral, soft coral, macroalgae, turf algae, etc.), morphology (Tier 2: massive, branching, upright macroalgae, etc.), and genus (Tier 3). The detailed list of each functional group level or tier is included in the benthic image analysis classification scheme. (Citation: Lozada-Misa P, Schumacher BD, Vargas-Angel B. 2017. Analysis of benthic survey images via CoralNet : a summary of standard operating procedures and guidelines. Pacific Islands Fisheries Science Center, PIFSC Administrative Report, H-17-02, 169 p.)
- Raw survey data includes unique image name, individual point observations identified at three levels, and the corresponding physical data that reflect the description of the site. The physical data includes: region, island, site, date, latitude, longitude, reef zone, and depth.
(describe or provide URL of description):
Quality control is enforced by means of point-to-point, inter-observer calibration exercises that are conducted before each image analysis production series. Additionally, training modules and standard operating procedures have been developed and documented to ensure improved performance and consistent analysis results produced by multiple analysts.
6. Data Documentation
The EDMC Data Documentation Procedural Directive requires that NOAA data be well documented, specifies the use of ISO 19115 and related standards for documentation of new data, and provides links to resources and tools for metadata creation and validation.

7. Data Access
NAO 212-15 states that access to environmental data may only be restricted when distribution is explicitly limited by law, regulation, policy (such as those applicable to personally identifiable information or protected critical infrastructure information or proprietary trade information) or by security requirements. The EDMC Data Access Procedural Directive contains specific guidance, recommends the use of open-standard, interoperable, non-proprietary web services, provides information about resources and tools to enable data access, and includes a Waiver to be submitted to justify any approach other than full, unrestricted public access.

Discuss data back-up, disaster recovery/contingency planning, and off-site data storage relevant to the data collection
The image analysis data is captured in two different locations: exported files from CPCe or CoralNet that reside on a file server, which are ingested into a table in the PIFSC Oracle database. Both the file server and PIFSC Oracle database are maintained and regularly backed up by PIFSC ITS.
