The data described here are benthic habitat imagery that result from benthic photo-quadrat surveys conducted along transects at stratified random sites across the Mariana archipelago since 2014 as a part of Rapid Ecological Assessment (REA) surveys for corals and fish.
A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems across the region. 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. Sampling effort was allocated based on strata area and sites were randomly located within strata. Sites were surveyed using photo-quadrats along transects to collect benthic imagery to ultimately produce estimates of relative abundance (benthic 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.

Abstract: |
The data described here are benthic habitat imagery that result from benthic photo-quadrat surveys conducted along transects at stratified random sites across the Mariana archipelago since 2014 as a part of Rapid Ecological Assessment (REA) surveys for corals and fish. A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems across the region. 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. Sampling effort was allocated based on strata area and sites were randomly located within strata. Sites were surveyed using photo-quadrats along transects to collect benthic imagery to ultimately produce estimates of relative abundance (benthic 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 NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the 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. |
Supplemental Information: |
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 PIFSC Ecosystem Sciences Division (ESD) 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. Since 2019, the fish and benthic teams conduct the photoquadrat surveys along one 30-m transect. Historically (2014 -2019), the fish team conducted the photoquadrat surveys along one 30-m transect and the benthic team conducted the surveys along 2 independent 18-m transects. Therefore, the site level image data contain 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. The data management team also uses a optical validation script to re-name photos and enforce several validation checks. |

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

Process Steps
Process Step 1
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. 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 two-stage sampling scheme following Cochran (1977) was employed to control for spatial variation in population parameters at scales smaller than the grid cell minimum mapping unit (2,500 m2). Grid cells containing hard-bottom reef habitats were designated as primary sample units (referred to as sites). |

Process Step 2
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 lines with a high-resolution digital camera mounted on a pole. Overall, 30 photoquadrat images are collected at each site. Benthic substrate photos are taken at one meter intervals along one 30 m transect line. Historically (2014-2019), the benthic team conducted the photoquadrat surveys 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; Transect A and B). 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, historically referred to as Transect A from 2014-2019). |

Process Step 3
Description: |
Raw data include ~30 benthic photographs per survey site. Included in the archive package is a list of survey sites, including site, date (day, month, year), latitude (dd), and longitude (dd) where photoquads were collected. The file naming convention for each photo/image is [SITE]_[YEAR]_[TRANSECT]_[PHOTO_NUMBER].JPG (for example: TUT-903_2012_A_01.JPG). |
