Abstract:

The data described here are benthic habitat imagery (color-corrected photographs) from benthic photo-quadrat surveys conducted along transects at stratified random sites by the Pacific Islands Fisheries Science Center (PIFSC) Ecosystem Sciences Division (ESD)--formerly the Coral Reef Ecosystem Division--as part of the NOAA National Coral Reef Monitoring Program (NCRMP). The photo-quadrat surveys are part of Rapid Ecological Assessment (REA) surveys for corals and fish conducted during ESD-led NCRMP missions across the Hawaiian Archipelago in 2013, 2016, and 2019.

A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems across the Hawaiian Archipelago. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0-30 m depth range. The stratification scheme included island, reef zone, and depth in all regions, as well as habitat structure type in the Main Hawaiian Islands. Allocation of sampling effort was proportional to strata area and variance in coral density. Sites were surveyed using photo-quadrats along transects to collect benthic imagery to ultimately produce estimates of relative abundance (percent cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.

The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than sampling more transects at a site. Therefore, site-level estimates and site to site comparisons should be used with caution.

Purpose:

The NOAA National Coral Reef Monitoring Program (NCRMP) details a long-term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP coordinates various Coral Reef Conservation Coral Reef Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of NCRMP, NOAA is able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis.

NCRMP is a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), and many other partners. The Ecosystem Sciences Division at NOAA Fisheries is leading biological monitoring in the U.S. Pacific Islands Region.

The biological component of NCRMP in the Pacific provides a triennial ecological characterization at a broad spatial scale of general reef condition for reef fishes, corals and benthic habitat (i.e., fish species composition/density/size, benthic cover, and coral density/size/condition). Innovative analysis techniques are then used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region’s resources and how they are changing over time.

Data Quality

Accuracy:

Handheld GPS units were used to locate random sites and mark site locations.

Analytical Accuracy:

Image data include ~30 benthic photographs per survey site from both the fish and benthic team surveys. The fish team conducts the photoquadrat surveys along one 30-m transect, as does the benthic team since 2018. Prior to 2018, the benthic team conducted surveys along 2 independent 18-m transects. Therefore, the site level image data prior to 2018 contains one transect (A) for fish team surveys and two transects (A and B) for benthic team surveys. Appropriate site level image grouping should include all 30 images.

Completeness Report:

Only shallow water (0 to 30 meter depth range) hard-bottom habitats are surveyed. The survey sites were randomly selected using a systematic process based on available habitat and bathymetric data. Although efforts are made to include broad spatial coverage of surveys at each island, weather conditions and other environmental constraints may have prevented the team from surveying exposed reef areas.

Conceptual Consistency:

The same methods of data collection were used at each surveyed site.

Quality Control Procedures Employed:

The photos are reviewed by the diver for accuracy and usability. To ensure consistency, images were color corrected using Adobe Lightroom if it appeared that the camera they were taken from was not properly white balanced in the field. The data management team also uses a optical validation script to re-name photos and enforce several validation checks.

The stratified random sampling (StRS) design and benthic photoquadrat survey methodology, employed by the NOAA Ecosystem Sciences Division (ESD) from 2013 to 2019. Benthic imagery is collected at stratified random sites. These photos are color-corrected (if necessary) prior to analysis. The data management team also uses an optical validation script to re-name photos and enforce several validation checks.

Process Steps

Process Step 1

CC ID: 369673
Description:

A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems through the U.S. Pacific regions. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats. The stratification scheme included island, reef zone, and depth in all regions, as well as habitat structure type in the Main Hawaiian Islands. The habitat structure types included simple, complex, and coral-rich. Depth categories of shallow (0-6 m), mid (> 6-18m) and deep (>18-30 m) were also incorporated into the stratification scheme. Allocation of sampling effort was proportional to strata area and variance in coral density . Sites were randomly selected within each stratum.

A geographic information system (GIS) and digital spatial databases of benthic habitats (NOAA National Centers for Coastal Ocean Science NCCOS), reef zones (IKONOS satellite imagery, NDGC 1998) bathymetry (NDGC 1998, CREP benthic mapping data), and marine reserve boundaries (NOAA) were used to facilitate spatial delineation of the sampling survey domain, strata, and sample units. Map resolution was such that the survey domain could be overlain by a grid using a GIS with individual cells of size 50 m by 50 m in area. A one-stage sampling scheme following Cochran (1977) was employed. Grid cells containing hard-bottom reef habitats were designated as primary sample units (referred to as sites).

Process Step 2

CC ID: 372125
Description:

Photoquadrat surveys were conducted by both the fish and benthic teams. Still photographs were collected to record the benthic community composition at predetermined points along the transect line with a high-resolution digital camera mounted on a pole. Overall, 30 photoquadrat images are collected at each site. The fish team conducts these surveys along one 30 meter transect that spans the length of two stationary point count (SPC) cylinders used to assess fish abundance (30 images total, Transect A). As of 2018, the benthic team conducts the photoquadrat surveys along one 30m transect, where one photo is taken every meter for a total of 30 photographs.

To ensure consistency, images were color corrected using Adobe Lightroom if it appeared that the camera they were taken from was not properly white balanced in the field. Raw data include 30 benthic photographs per survey site. Included in the archive package is a list of survey sites, including region, island, site, date (day, month, year), latitude (dd), longitude (dd), minimum depth (ft), and maximum depth where photoquads were collected and unique image name. The file naming convention for each photo/image is [SITE]_[YEAR]_[TRANSECT]_[PHOTO_NUMBER].JPG (for example: TUT-903_2012_A_01.JPG).
