Data Management Plan
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
This metadata record describes the imagery collected in 2022 of Aua Reef, American Samoa by the Ecosystem Sciences Division (ESD) of NOAA, funded by the Coral Reef Conservation Program (CRCP), to study effects of land-based source pollution by establishing biological, physical, and chemical baselines.
In September 2022, NOAA scientists conducted benthic survey protocols at 18 study sites in Aua, American Samoa. The surveys implemented a one-stage stratified random sampling (StRS) design and the survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0 to 6 m depth range. Photoquadrat benthic images were collected along belt transect surveys of coral demography according to protocols established by NOAA National Coral Reef Monitoring Program (NCRMP) in 2015.
Thirty images were collected along one, haphazardly laid, 30-m transects. Still photographs were collected to record the benthic community composition at predetermined points along belt transect with a high-resolution digital camera mounted on a pole. Photographs were taken every 1 m from the 1 m to the 30 m mark. This work generates 30 photographs per site, which are later analyzed by ESD staff and partners using the computer program CoralNet. This analysis is the basis for estimating benthic cover and composition at each site, which is documented and archived separately.
The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than more transects per site. Therefore, site-to-site comparisons should proceed with caution.

Benthic photographs were collected during belt transect surveys of corals by the NOAA Ecosystem Sciences Division (ESD) following the same protocol to that established by the NOAA National Coral Reef Monitoring Plan (NCRMP). BV ADD / MENTION THE COMPLEMENTARY IMAGERY / SITES COLLECTED AND HOW THEY WERE SELECTED
- Biological surveys implemented a modified stratified random sampling design to assess the survey domain which encompassed the hard-bottom reef habitat of Aua from 0 to 6 m in depth, and between the Aua stream mouth to the Onesosopo Park. Based on the nature and scientific questions addressed in this study, the survey domain was divided into three categorical LBSP impact sectors (15-20 Ha each) based on their distance from the source of disturbance as follows: High Impact, Medium Impact, and Low impact. Subsequently a digital map of the survey domain was overlaid with a 50 m x 50 m (2500 m2 in area) GIS layer, and grid cells containing hard-bottom reef habitat were designated as the sampling units, hereafter referred to as survey sites. Depending on the number of 50 m x 50 m grid cells fitting within, four to eight randomly selected survey sites were allocated within each categorical impact sectors. One, haphazardly laid, 30-m belt-transect was the focal point of the photoquadrat survey. Still photographs were collected to record the benthic community composition with a high-resolution digital camera mounted on a pole. Thirty photographs were taken every meter from the 1 m to the 30 m mark. This work generates 30 photographs per site, which are later analyzed by ESD staff and partners using the computer program CoralNet. Survey protocols followed the National Coral Reef Monitoring Program methodologies historically implemented by NOAA's Ecosystem Sciences Division.

Instrumentation and camera setting are updated periodically to improve image quality. The photos are reviewed by the diver for accuracy and usability. The data management team also uses a optical validation script to re-name photos and enforce several validation checks. Images are color corrected prior to analysis.
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.
