The data described here result from benthic coral demographic surveys within belt transects of specified length and width for two life stages (juveniles and adults) across American Samoa since 2015. The data provide information on adult coral colony counts, morphology, size, partial mortality (old and recent dead), presence and causation of disease and other compromised health conditions, including bleaching. Juvenile colony surveys include morphology and size. Taxonomic identification of adult colonies is to the species level and genus level for juveniles. In 2023, some segment observations were repeated for internal quality control; to filter for non-repeated data, be certain filter for TRANSECTNUM = 1. A two-stage stratified random sampling (StRS) design was employed to survey the coral reef ecosystems of American Samoa in 2015, and starting in 2018 a one-stage StRS design was employed. 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 (i.e., shallow: >0 - 6 m; mid-depth: > 6 -18 m; and deep: >18 - 30 m), as well as reef zone (i.e., forereef, backreef, and lagoon; backreef only at Rose Atoll and Tutuila, and lagoon only at Rose Atoll). Sampling effort allocation was determined based on strata area and sites randomly located within strata. 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-level estimates and site-to-site comparisons should proceed with caution. The data were collected as part of the NOAA Pacific Islands Fisheries Science Center (PIFSC) and Ecosystem Sciences Division (ESD; formerly the Coral Reef Ecosystem Division) led National Coral Reef Monitoring Program (NCRMP) missions to American Samoa. The 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 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.

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. 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. false eng false Data View View: V0_CORAL_OBS_E 2025-09-18 publication View: V0_CORAL_OBS_F 2025-09-18 publication View: V0_CORAL_OBS_E_PRESENCE 2025-09-18 publication CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) CSV - Comma Separated Values (Text) PDF - Adobe Portable Document Format ERDDAP Data Service ERDDAP Data Service PDF - Adobe Portable Document Format PDF - Adobe Portable Document Format NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact WWW:LINK-1.0-http--link NCEI Contact Information Information for contacts at NCEI. information distributor https://accession.nodc.noaa.gov/0159173 WWW:LINK-1.0-http--link V0_CORAL_OBS_E_ SAMOA 2015.csv Adult coral colony observations from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across American Samoa in 2015 (HA1501 and MP1602). download https://accession.nodc.noaa.gov/0159173 WWW:LINK-1.0-http--link SAMOA2015_coralgenera.csv List of coral genera surveyed in American Samoa download https://accession.nodc.noaa.gov/0159173 WWW:LINK-1.0-http--link V0_CORAL_OBS_E_PRESENCE SAMOA 2015.csv Presence / absence from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across American Samoa in 2015 (HA1501 and MP1602). download https://accession.nodc.noaa.gov/0159167 WWW:LINK-1.0-http--link V0_CORAL_OBS_E_PRESENCE SAMOA 2016.csv Presence / absence from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across Rose Atoll in 2016 (SE1602). download https://accession.nodc.noaa.gov/0159173 WWW:LINK-1.0-http--link SAMOA2015_coralspecies.csv List of coral species surveyed in American Samoa download https://accession.nodc.noaa.gov/0159167 WWW:LINK-1.0-http--link SAMOA2016_coralgenera.csv List of coral genera surveyed in American Samoa download https://accession.nodc.noaa.gov/0159167 WWW:LINK-1.0-http--link V0_CORAL_OBS_E_ SAMOA 2016.csv Adult coral colony observations from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across Rose Atoll in 2016 (SE1602). download https://accession.nodc.noaa.gov/0159167 WWW:LINK-1.0-http--link V0_CORAL_OBS_F SAMOA 2016.csv Juvenile coral colony observations from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across Rose Atoll in 2016 (SE1602). download https://accession.nodc.noaa.gov/0159173 WWW:LINK-1.0-http--link V0_CORAL_OBS_F SAMOA 2015.csv Juvenile coral colony observations from coral demographic surveys of stratified random sites by the NOAA Coral Reef Ecosystem Program (CREP) conducted across American Samoa in 2015 (HA1501 and MP1602). download https://accession.nodc.noaa.gov/0157633 WWW:LINK-1.0-http--link PIFSC_NTM-PIFSC-92_2018_SOP_Benthic.pdf Winston M, Couch C, Ferguson M, Huntington B, Swanson D, Vargas-Ángel B. 2019.

PIFSC Data Report DR-18-016. https://doi.org/10.25923/dt06-y997 download dataset Accuracy This data should be assessed at the genus level due to variabilities in identifying at genus or species level. Observations were made by experienced benthic survey personnel who have been trained, undergone a series of calibration surveys and coral taxon identification testing, and have met a set of minimum standards for colony assessment and taxon identification in each region. The accuracy of species and genus level identification was high. The lowest taxonomic level of coral identification was genus except for a select number of species that were consistently identified to species by all divers conducting the surveys. The number of species may change for each survey year depending on the experience and training of the benthic divers. The list of coral species is included for each survey year. In other words, the individual records within each data set may include many more species than encompassed by the lists; however, these were not consistently identified across all surveys so these records should be assessed at the genus level. Handheld GPS units were used to locate random sites and mark site locations. Analytical Accuracy The taxon code AAAA is included where the segment was surveyed and no individual colonies were found in both the juvenile and adult colony records. These are true zeros. The value -9 is a placeholder or missing value for the fields: colony length, colony width (juveniles), extent, and severity. 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. The value -9 has been used a placeholder or missing value for several fields. See the entities and attributes under 'child items'. Conceptual Consistency The same methods of data collection are used at each surveyed site. Periodic examination of the data is conducted throughout each mission to check for diver bias or other discrepancies. The stratified random sampling (StRS) design and belt transect methodology for adult and juvenile corals, employed by the PIFSC Ecosystem Sciences Division (ESD) since 2013. A two-stage StRS design was employed in 2015 and a one-stage design was employed in 2018. A stratified random sampling (StRS) design was employed to survey the coral reef ecosystems in the region (two-stage StRS in 2015, one-stage StRS in 2018). 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. Depth categories of shallow (>0-6 m), mid (>6-18 m) and deep (>8-30 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, ESD 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. The 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 sq. meters). Grid cells containing hard-bottom reef habitats were designated as primary sample units (referred to as sites), while the second-stage sample unit was defined as a diver visual belt transect of fixed area (10 sq. meters or less). The primary sample units were the same for both sampling schemes (one-stage and two-stage). Oliver, Thomas (808)725-5444 thomas.oliver@noaa.gov processor At each site, benthic Rapid Ecological Assessment (REA) surveys were conducted within two 10 sq. meter belt transects in 2015 and within one 10 sq. meter belt transect after 2018. Transects were 18 meters in length. Adult coral colonies (>=5 cm) were surveyed within four (1.0 x 2.5 m) segments at 5 meter increments along the 18 meter transect in the following manner: 0-2.5 m (segment 1); 5.0-7.5 m (segment 3); 10-12.5 m (segment 5); and 15-17.5 m (segment 7). All colonies whose center fell within 0.5 m on either side of each transect line were identified to lowest taxonomic level possible (species or genus), measured for size (maximum diameter to nearest cm), and morphology was noted. In addition, partial mortality and condition of each colony was assessed. Partial mortality was estimated as percent of the colony in terms of old dead and recent dead. The cause of recent mortality was identified if possible. The condition of each colony including disease (not attributed to recent tissue loss) and bleaching was noted along with the extent (percent of colony affected) and level of severity (range from moderate to acute). The lowest taxonomic level of coral identification was genus except for a select number of species consistently identified to species by all divers conducting the surveys. The number of species may change for each survey year depending on the experience and training of the benthic divers conducting the surveys. The list of coral species is included for each survey year. Within the same four segments per transect as the adult coral surveys, crustose coralline algae (CCA) diseases and Alcyonarian disease are surveyed. In each segment, each occurrence of a specific disease is identified and the lesion is measured (maximum diameter). In addition to the adult coral surveys, CCA diseases, and Alcyonarian disease, the presence of other Anthozoans (other cnidarians including Alcyonareans, Zoantharians, coralliomorphs and Antipatharians) are also noted. These data exist as individual records coded for each group. This portion of the survey was not conducted after 2018. Juvenile coral colonies (<5 cm) were surveyed within three (1.0 x 1.0 m) segments along the same two transects in 2015 or along the single transect in 2018: 0-1.0 m (segment 1); 5.0-6.0 m (segment 3); and 10.0-11.0 m (segment 5). Juvenile colonies were distinguished in the field by a distinct tissue and skeletal boundary (not a fragment of a larger colony). Each juvenile colony was identified to lowest taxonomic level (genus or species) and measured for size by recording both the maximum and perpendicular diameter to the nearest 2 mm. Oliver, Thomas (808)725-5444 thomas.oliver@noaa.gov processor Raw data include individual colony records with the corresponding physical data which reflect the description of the site. An individual colony record for adult corals includes colony species/genus identification, morphology, maximum diameter (cm), percent old dead, percent recent dead, cause of recent dead general category, cause of recent dead specific category, condition, extent and severity. Juvenile coral colony records include colony species/genus identification, morphology, maximum diameter (cm) and perpendicular diameter (cm). For species level identification of adult and juvenile corals, check the species list for each year to ensure species identification across all divers conducting the surveys. Individual records for crustose coralline algae diseases use the taxon code CALG and the Alcyonarian disease uses the taxon code for the octocoral genus. The colony length measurement is the maximum diameter of the lesion for both disease types. The raw presence/absence data for other Anthozoans include the general identification code and 0 or -1 to represent absence or presence respectively. The physical data for all records includes the following: region, island, site, date (day, month, year), latitude (dd), longitude (dd), transect, segment, segment length, segment width, minimum depth (ft), and maximum depth.
