The original habitat model is clipped to a habitat buffer created by the Utah Division of Wildlife Resources. The data contains a clipped polygon for nesting, summer, and winter habitat respectively.\u00a0</div><div><br /></div><div>Process of creating habitat model, as described by the authors: The process of creating the seasonal habitats layer is described below.</div><div><br /></div><div>1. Creation of statewide general habitat model for GRSG (2016). In 2016, researchers at Utah State University (USU) developed a statewide general sage-grouse habitat map using a database of hundreds of lek locations and more than 20,000 GRSG telemetry locations collected statewide from 1998 \u2013 2014. The map depicted habitat suitability on a scale from 0 to 100 at 1 km spatial resolution, based on comparing environmental (vegetation, topography, soils, climate) and anthropogenic (developed land cover, road density, powerline density) conditions at active lek and sage-grouse use locations versus inactive lek and random background locations statewide. Because multiple telemetry locations were often associated with a single brood-rearing or non-breeding bird, the median values of environmental and anthropogenic variables at these telemetry locations were used in the model. A random forest model was used to create the map (Breiman 2001, Cutler et al. 2007). Random forests is a highly accurate non-parametric classification technique that predicts the probability of an outcome (in this case, habitat vs non-habitat) by averaging the results of many classification trees, each of which is trained on a random subset of the available data. The general habitat map was reclassified into \u2018habitat\u2019 and \u2018non-habitat\u2019 classes such that habitat areas captured 99% of all sage-grouse use locations. These general habitat areas were used as a mask in order to constrain preliminary predictions of seasonal habitats, described below.</div><div><br /></div><div>2. Create preliminary seasonal GRSG habitat models (Jan - May 2017). Telemetry locations in the database were classified into three seasonal habitat types based on time of year and type of GRSG use. Breeding habitat was defined as areas used by GRSG engaged in lekking, nesting, and early brood-rearing, from March 1 \u2013 June 14. Summer habitat was defined as areas used by brood-rearing and non-breeding GRSG from June 15 \u2013 August 31. The June 15 cutoff date between breeding and summer use locations was selected based on the temporal distribution of nesting and brooding use locations. Winter habitat was defined as areas used by non-breeding GRSG from November 1 \u2013 February 29. As in the general habitat modeling approach, environmental conditions at annual brood-rearing or non-breeding locations associated with the same bird were measured as medians over the multiple locations. Seasonal habitats were modeled using the same predictors as the general habitat model, with the addition of distance to leks due to its association with breeding habitat. A random forest model was used to estimate the suitability of general habitat areas statewide (from step 1 above) for breeding, summer, and winter use. For each seasonal use class, a suitability threshold was selected such that 85% of all seasonal use locations were captured in the resulting seasonal habitat map. This resulted in models that were neither overly restrictive nor overly liberal. To reduce the 'salt and pepper\u2019 effect of isolated or scattered habitat pixels, a 3x3 km smoothing window was applied to each of the seasonal habitat layers, assigning the majority value (habitat or non-habitat) to the center pixel.\u00a0</div><div><br /></div><div>3. DWR biologists reviewed seasonal models (April - June 2017). An overview of the general and seasonal mapping methodology and preliminary maps was presented to GRSG biologists and managers from the Utah Division of Wildlife Resources (UDWR), Bureau of Land Management (BLM), and Forest Service (FS) at Utah State University in Logan on 4/21/17. Feedback at the meeting led to a few minor changes to the seasonal mapping methods. Because the breeding seasonal use model was not picking up areas around all active leks, distance to leks was dropped as a predictor variable from the seasonal habitat random forest model, and a 3 km buffer around all active leks was manually included in the breeding habitat model. Updated seasonal use models were sent to UDWR on 5/17/17, where they were made available for review by biologists with local area knowledge. An ArcGIS Online webpage was used to share the models with biologists, and allow for them to provide recommended additions / deletions to areas captured by the models. Accompanying the spatial data was an 8 minute webinar communicating the modelling procedure. UDWR returned updated seasonal use models with biologists\u2019 comments, additions, and deletions to USU researchers on 6/6/17. Most but not all areas in the state received substantive feedback and comments from UDWR biologists.\u00a0</div><div><br /></div><div>4. Additional review of seasonal use models and final edits performed (July \u2013 August 2017). USU researchers reviewed biologist edits on 7/13/17. Most of the areas flagged to be added/removed from the seasonal use models seemed appropriate and helpful. But, there were a few areas UDWR biologists identified to be deleted from the models that USU researchers considered questionable. These areas were identified and shared with UDWR managers on 7/13/17. UDWR managers indicated a desire to have another face to face meeting to make a final determination on areas to include / exclude from the seasonal use models. This meeting occurred on 8/8/17, at which it was determined that it would be preferable to have the final seasonal habitat products reflect both use and potential suitability, as opposed to only areas of known use. This led to rejecting some areas flagged for deletion by biologists, as biologist comments indicated they were conceptualizing the map as primarily a use map only. Numerous small edits were made to the seasonal use layers, including several edits to include seasonal use locations not captured by preliminary models. Finally, all single, isolated habitat pixels were removed from the map.\u00a0</div><div><br /></div><div>References: Breiman, L.

The original habitat model is clipped to a habitat buffer created by the Utah Division of Wildlife Resources. The data contains a clipped polygon for nesting, summer, and winter habitat respectively.\u00a0</div><div><br /></div><div>Process of creating habitat model, as described by the authors: The process of creating the seasonal habitats layer is described below.</div><div><br /></div><div>1. Creation of statewide general habitat model for GRSG (2016). In 2016, researchers at Utah State University (USU) developed a statewide general sage-grouse habitat map using a database of hundreds of lek locations and more than 20,000 GRSG telemetry locations collected statewide from 1998 \u2013 2014. The map depicted habitat suitability on a scale from 0 to 100 at 1 km spatial resolution, based on comparing environmental (vegetation, topography, soils, climate) and anthropogenic (developed land cover, road density, powerline density) conditions at active lek and sage-grouse use locations versus inactive lek and random background locations statewide. Because multiple telemetry locations were often associated with a single brood-rearing or non-breeding bird, the median values of environmental and anthropogenic variables at these telemetry locations were used in the model. A random forest model was used to create the map (Breiman 2001, Cutler et al. 2007). Random forests is a highly accurate non-parametric classification technique that predicts the probability of an outcome (in this case, habitat vs non-habitat) by averaging the results of many classification trees, each of which is trained on a random subset of the available data. The general habitat map was reclassified into \u2018habitat\u2019 and \u2018non-habitat\u2019 classes such that habitat areas captured 99% of all sage-grouse use locations. These general habitat areas were used as a mask in order to constrain preliminary predictions of seasonal habitats, described below.</div><div><br /></div><div>2. Create preliminary seasonal GRSG habitat models (Jan - May 2017). Telemetry locations in the database were classified into three seasonal habitat types based on time of year and type of GRSG use. Breeding habitat was defined as areas used by GRSG engaged in lekking, nesting, and early brood-rearing, from March 1 \u2013 June 14. Summer habitat was defined as areas used by brood-rearing and non-breeding GRSG from June 15 \u2013 August 31. The June 15 cutoff date between breeding and summer use locations was selected based on the temporal distribution of nesting and brooding use locations. Winter habitat was defined as areas used by non-breeding GRSG from November 1 \u2013 February 29. As in the general habitat modeling approach, environmental conditions at annual brood-rearing or non-breeding locations associated with the same bird were measured as medians over the multiple locations. Seasonal habitats were modeled using the same predictors as the general habitat model, with the addition of distance to leks due to its association with breeding habitat. A random forest model was used to estimate the suitability of general habitat areas statewide (from step 1 above) for breeding, summer, and winter use. For each seasonal use class, a suitability threshold was selected such that 85% of all seasonal use locations were captured in the resulting seasonal habitat map. This resulted in models that were neither overly restrictive nor overly liberal. To reduce the 'salt and pepper\u2019 effect of isolated or scattered habitat pixels, a 3x3 km smoothing window was applied to each of the seasonal habitat layers, assigning the majority value (habitat or non-habitat) to the center pixel.\u00a0</div><div><br /></div><div>3.

The source data for the mean day of the year of a first freeze, from 30 years of Record (1961-1990) was provided by the Environmental Protection Agency and is included with this data set (Ryan Hill, EPA, written commun., 2006). Values of 0 indicate there is no freeze. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale.

This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data for 30-year average (1961-1990) relative humidity (percent) was originally PRISM-based data, with some further enhancements by ClimateSource.com and then provided to the USGS by the Environmental Protection Agency (Ryan Hill, EPA, written commun., 2011). It should be noted this data set is discontinued and may be available only by contacting the PRISM Group at Oregon State University directly. Units are percent. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.

Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale.

Understanding local adaptation, in turn, informs management decisions such as translocation to restore locally-extinct populations. We used a landscape genomics approach to detect genetic signatures of selection related to climatic variation among desert bighorn sheep populations across their indigenous range in the western United States. This approach allowed us to investigate broad patterns of both neutral and adaptive genetic variation across very different environments. Analyses suggested that ancestry and isolation by distance were the most significant forces driving genetic variation in desert bighorn sheep, but that climate was associated with at least 1 locus (i.e., location on the genome) under directional selection. The alternate allele (i.e., variant) at this locus was associated with biologically significant increases in elevation and precipitation, decreases in temperature, and was nearly private to herds occupying the Great Basin ecosystem. Our results suggest climate conditions at higher latitudes may have resulted in a distinct ecotype of desert bighorn sheep whose adaptations are still apparent among the few remaining indigenous populations in the Great Basin. We also found 2 highly supported candidate genes in the genomic region linked to this outlier.

Understanding local adaptation, in turn, informs management decisions such as translocation to restore locally-extinct populations. We used a landscape genomics approach to detect genetic signatures of selection related to climatic variation among desert bighorn sheep populations across their indigenous range in the western United States. This approach allowed us to investigate broad patterns of both neutral and adaptive genetic variation across very different environments. Analyses suggested that ancestry and isolation by distance were the most significant forces driving genetic variation in desert bighorn sheep, but that climate was associated with at least 1 locus (i.e., location on the genome) under directional selection. The alternate allele (i.e., variant) at this locus was associated with biologically significant increases in elevation and precipitation, decreases in temperature, and was nearly private to herds occupying the Great Basin ecosystem. Our results suggest climate conditions at higher latitudes may have resulted in a distinct ecotype of desert bighorn sheep whose adaptations are still apparent among the few remaining indigenous populations in the Great Basin. We also found 2 highly supported candidate genes in the genomic region linked to this outlier. How the molecular function of these candidate genes may affect physiological response of desert bighorn sheep to climate is unclear, although their identification provides new insight into the genetic mechanisms potentially underlying environmental adaptation. We identified several other loci under strong directional selection not related to climate and described a previously unknown pattern of strong genetic divergence of bighorn sheep within the White Mountains compared to other populations.

The regression based Parameter-elevation Regressions on Independent Slopes Model (PRISM) uses spatial data sets, a knowledge base and expert interaction to generate GIS-compatible grids of climate variables. This study applied PRISM to generate maps of mean monthly and annual precipitation and minimum and maximum temperature for the Caribbean islands of Puerto Rico, Vieques and Culebra over the 1963\u20131995 averaging period. PRISM was run under alternative parameterizations that simulated simpler interpolation methods as well as the full PRISM model. For temperature, the standard PRISM parameterization was compared to a hypsometric method, in which the temperature/elevation slope was assumed to be -6.5\u00b0C/km (HYPS). For precipitation, the standard PRISM parameterization was compared to an inverse-distance weighting interpolation (IDW). Spatial temperature patterns were linked closely to elevation, topographic position, and coastal proximity. Both PRISM and HYPS performed well for July maximum temperature, but HYPS performed relatively poorly for January minimum temperature, due primarily to lack of a spatially varying temperature/elevation slope, vertical atmospheric layer definition, and coastal proximity guidance. Mean monthly precipitation varied significantly throughout the year, reflecting seasonally differing moisture trajectories. Spatial precipitation patterns were associated most strongly with elevation, upslope exposure to predominant moisture-bearing winds, and proximity to the ocean.

The three climatic variables included in the dataset are total precipitation (inches), maximum temperature (degrees Fahrenheit), and minimum temperature (degrees Fahrenheit). PRISM Climate Group at Oregon State University used climate observations from monitoring stations and interpolated to a gridded format using the PRISM model (Parameter-elevation Regressions on Independent Slopes Model). Interpolation was trained using a DEM (digital elevation model) to improve performance in mountainous regions.  \n\t\t\n\t\tDatasets for other the U.S. Virgin Islands was produced separately; metadata for the U.S. VI datasets may be found here: https://enviroatlas.epa.gov/enviroatlas/MetadataFGDC/PRISM_30yr_normals_USVI_1971_2000.xml\n\nThe PRISM temperature data were originally reported in \u00b0C but were converted to \u00b0F. The PRISM precipitation data were originally reported in millimeters but were converted to inches.\n\nThis dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).\n\nOriginal PRISM Metadata (https://prism.oregonstate.edu/normals_other/public/pr/metadata/): \n\nAbstract: \n\nMonthly 33-year \"normal\" dataset covering Puerto Rico, averaged over the climatological period 1963\u20131995. Contains spatially gridded average annual precipitation and temperature at 450m grid cell resolution. Distribution of the point measurements to the spatial grid was accomplished using the PRISM model, developed and applied by Dr. Christopher Daly of the PRISM Climate Group at Oregon State University. This dataset was heavily peer reviewed, and is available free-of-charge on the PRISM website.\n\nPurpose:\n\nDisplay and/or analysis requiring spatially distributed annual precipitation and temperature for the climatological period 1963\u20131995.\n\nSupplementary Information: \n\nSpatially explicit climate data contribute to watershed resource management, mapping vegetation type with satellite imagery, mapping present and hypothetical future ecological zones, and predicting species distributions. The regression based Parameter-elevation Regressions on Independent Slopes Model (PRISM) uses spatial data sets, a knowledge base and expert interaction to generate GIS-compatible grids of climate variables. This study applied PRISM to generate maps of mean monthly and annual precipitation and minimum and maximum temperature for the Caribbean islands of Puerto Rico, Vieques and Culebra over the 1963\u20131995 averaging period. PRISM was run under alternative parameterizations that simulated simpler interpolation methods as well as the full PRISM model. For temperature, the standard PRISM parameterization was compared to a hypsometric method, in which the temperature/elevation slope was assumed to be -6.5\u00b0C/km (HYPS). For precipitation, the standard PRISM parameterization was compared to an inverse-distance weighting interpolation (IDW). Spatial temperature patterns were linked closely to elevation, topographic position, and coastal proximity. Both PRISM and HYPS performed well for July maximum temperature, but HYPS performed relatively poorly for January minimum temperature, due primarily to lack of a spatially varying temperature/elevation slope, vertical atmospheric layer definition, and coastal proximity guidance. Mean monthly precipitation varied significantly throughout the year, reflecting seasonally differing moisture trajectories. Spatial precipitation patterns were associated most strongly with elevation, upslope exposure to predominant moisture-bearing winds, and proximity to the ocean. IDW performed poorly compared to PRISM, due largely to the lack of elevation and moisture availability information. Overall, the full PRISM approach resulted in greatly improved performance over simpler methods for precipitation and January minimum temperature, but only a small improvement for July maximum temperature. Comparisons of PRISM mean annual temperature and precipitation maps to previously-published, hand-drawn maps showed similar overall patterns and magnitudes, but the PRISM maps provided much more spatial detail.","distribution_titles":[],"harvest_record":"https://catalog.data.gov/harvest_record/0d69ca0d-88f6-4d7f-ac35-6da94d668b05","harvest_record_raw":"https://catalog.data.gov/harvest_record/0d69ca0d-88f6-4d7f-ac35-6da94d668b05/raw","harvest_record_transformed":"https://catalog.data.gov/harvest_record/0d69ca0d-88f6-4d7f-ac35-6da94d668b05/transformed","has_download":true,"has_spatial":true,"identifier":"https://edg.epa.gov/WAFer_harvest/ISO/enviroatlas-metadata-waf_PRISM_30yr_normals_PR_1963_1995.xml","keyword":["Puerto Rico","United States","Climate","Ecosystem","Environment","Hazards","Human","Impact","Modeling","Risk","Water","020:072","Ecosystem Services","EnviroAtlas","Environment","Environmental Atlas","Human Well-being","Sustainability"],"last_harvested_date":"2026-08-29T18:51:50.168447","organization":{"aliases":["EPA"],"code_repo_exempt":false,"code_repo_url":null,"description":null,"id":"82b85475-f85d-404a-b95b-89d1a42e9f6b","logo":"https://raw.githubusercontent.com/GSA/logo/refs/heads/master/epa.png","name":"U.S. Environmental Protection Agency","organization_type":"Federal Government","slug":"epa"},"parent_identifier":null,"popularity":0,"publisher":"U.S. EPA Office of Research and Development (ORD) - Center for Public Health and Environmental Assessment (CPHEA)","slug":"enviroatlas-prism-30-year-normal-annual-precipitation-and-minimum-and-maximum-temperature--06f86","spatial_centroid":{"lat":18.1417158,"lon":-65.9242356},"spatial_shape":{"coordinates":[[[-64.992242,17.864565],[-64.992242,18.557442],[-67.322226,18.557442],[-67.322226,17.864565],[-64.992242,17.864565]]],"type":"Polygon"},"theme":["geospatial"],"title":"EnviroAtlas - PRISM 30-Year Normal Annual Precipitation and Minimum and Maximum Temperature for Puerto Rico (1963\u20131995)","type":"dataset"},{"_score":25.293087,"_sort":[1788029037524,25.293087,4,"c47cbd15-79c9-46f5-aed1-d12e17d259cb"],"dcat":{"accessLevel":"public","bureauCode":["010:12"],"contactPoint":{"@type":"vcard:Contact","fn":"Michael E.

The index was intended to provide an indication of the expected aggregate benefits of the implementation of a suite of management practices.","distribution_titles":["Digital Data","Original Metadata"],"harvest_record":"https://catalog.data.gov/harvest_record/efe59961-948a-47af-8a22-7b2ef6b61b0b","harvest_record_raw":"https://catalog.data.gov/harvest_record/efe59961-948a-47af-8a22-7b2ef6b61b0b/raw","has_download":true,"has_spatial":true,"identifier":"http://datainventory.doi.gov/id/dataset/USGS_5cc89237e4b09b8c0b77f247","keyword":["NHDPlus Version 2.1","USGS:5cc89237e4b09b8c0b77f247","best management practice","inlandWaters","nitrogen","phosphorous","sediment"],"last_harvested_date":"2026-08-29T18:33:31.414809","organization":{"aliases":["dept"],"code_repo_exempt":false,"code_repo_url":null,"description":null,"id":"143529f7-2eef-4a07-b227-93ac9e84fad8","logo":"https://raw.githubusercontent.com/GSA/logo/master/doi.png","name":"Department of the Interior","organization_type":"Federal Government","slug":"doi"},"parent_identifier":null,"popularity":3,"publisher":"U.S. Geological Survey","slug":"attributes-for-nhdplus-version-2-1-reach-catchments-and-modified-routed-upstream-watershed-1c7bd","spatial_centroid":{"lat":34.60906,"lon":-102.87759999999999},"spatial_shape":{"coordinates":[[[-127.9108,23.2435],[-127.9108,51.6574],[-65.3278,51.6574],[-65.3278,23.2435],[-127.9108,23.2435]]],"type":"Polygon"},"theme":["geospatial"],"title":"Select Best Management Practices Attributes: National Resource Conservation Service's Best Management Practice Scenarios for Total Non-Gas Nitrogen, Phosphorous, and Sediment","type":"dataset"},{"_score":28.056286,"_sort":[1788028228106,28.056286,1,"7f9e663f-9a2d-49a7-aca3-a21667b80ea0"],"dcat":{"accessLevel":"public","bureauCode":["010:12"],"contactPoint":{"@type":"vcard:Contact","fn":"Michael E.

A dry event is defined as a period when the number of consecutive days with precipitation equals 0 millimeters. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data for 30 year (1981-2010) average of annual maximum duration of consecutive dry and wet days per event was a 1-kilometer resolution GeoTIFF file that was produced and acquired from DAYMET (2018).

The HOT program makes repeated observations of the physics, biology and chemistry at a site approximately 100 km north of Oahu, Hawaii. The program began in 1988. Two stations are visited about once a month: Kahe Point (Station 1: 21.34N, 158.27W) and Station ALOHA (Station 2: 22.75N, 158W). Various other stations are made intermittently in support of similar research objectives or mooring deployments.\n\nThis dataset also includes physical-biogeochemical measurements from Station HALE-ALOHA (Hawai'i Air-sea Logging Experiment, A Long-Term Oligotrophic Habitat Assessment), measurements of high-quality air-sea fluxes and the associated upper ocean response from The Woods Hole Oceanographic Institution (WHOI) Hawaii Ocean Timeseries (HOT) Site (WHOTS), as well as hydrographic and biogeochemical parameters from the ALOHA-CLIMAX Regional Study.","distribution_titles":["NCEI Dataset Landing Page","Granule Search","https://hahana.soest.hawaii.edu/stationaloha/","Hawaii ocean time-series program data report","GCMD Keyword Forum Page","NCEI Contact Information","NOAA Library website"],"harvest_record":"https://catalog.data.gov/harvest_record/d28c8b15-7d73-45de-9d55-1bb9f6afc25b","harvest_record_raw":"https://catalog.data.gov/harvest_record/d28c8b15-7d73-45de-9d55-1bb9f6afc25b/raw","harvest_record_transformed":"https://catalog.data.gov/harvest_record/d28c8b15-7d73-45de-9d55-1bb9f6afc25b/transformed","has_download":false,"has_spatial":true,"identifier":"https://data.noaa.gov/waf/NOAA/NESDIS/ncei/accessions/iso/xml/Station-ALOHA-HOT.xml","keyword":["0000497","0000639","0000640","0000641","0001016","0001704","0001707","0001710","0010624","0010740","0011142","0041594","0041849","0042029","0046427","0048660","0048725","0048896","0059842","0059936","0059943","0068957","0069177","0069501","0087584","0087596","0087988","0088839","0089168","0101146","0101727","0103907","0119430","0119895","0120323","0125579","0125647","0125648","0140225","0218247","0224688","0224752","0224756","0224849","0242075","0276338","0284084","0298064","0308400","9300009","9300040","9300148","9300149","9300183","9700176","9800125","9900206","9900207","9900208","9900212","9900213","9900214","9900215","AIR TEMPERATURE","AIR TEMPERATURE -

These data were gathered around American Samoa as a part of NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led missions. During these missions, the variables of benthic complexity and urchin abundance were tracked by swimmer/diver visual surveys at NCRMP climate stations. Three to four of these sites were chosen per island in a stratified random fashion so as to be roughly equally spaced, along the 15m contour, on hard bottom, and at least 1 km away from a river mouth or embayment. Once the sites were selected, multiple features of the coral reef environment were assessed, including: in-situ temperature (STR), seawater carbonate, net carbonate accretion (CAU), bioerosion (BMU), and cryptobiota diversity (ARMS). These data, however, are archived separately.","distribution_titles":["CRCP Benthic Complexity Urchin Abundance Pacific","NCEI Dataset Landing Page","Granule

the analysis of images produced by benthic photo-quadrat surveys. These surveys were conducted along transects at stratified random sites across the Pacific Remote Island Areas since 2014 as a part of the ongoing National Coral Reef Monitoring Program's (NCRMP) Rapid Ecological Assessment (REA) surveys for corals and fish. Benthic cover data and the associated images are both included in this collection.\n\nA stratified random sampling (StRS) design was employed to survey the coral reef ecosystems throughout the U.S. Pacific regions. 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 (percent cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.\n\nBenthic habitat imagery were quantitatively analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill, 2006) software in 2014 and a web-based annotation tool called CoralNet (Beijbom et al. 2015) thereafter. In general, images were analyzed to produce three functional group levels of benthic cover: Tier 1 (e.g., hard coral, soft coral, macroalgae, turf algae, etc.), Tier 2 (e.g., Hard Coral = massive, branching, foliose, encrusting, etc.; Macroalgae = upright macroalgae, encrusting macroalgae, bluegreen macroalgae, and Halimeda, etc.), and Tier 3 (e.g., Hard Coral = Astreopora sp, Favia sp, Pocillopora, etc.; Macroalgae = Caulerpa sp, Dictyosphaeria sp, Padina sp, etc.).","distribution":[{"@type":"dcat:Distribution","accessURL":"https://www.ncei.noaa.gov/erddap/tabledap/CRCP_Benthic_Cover_PRIAs.html","describedByType":"application/octet-stream","description":"ERDDAP acts as a middleman between you and various remote data servers.

Coral Reef Monitoring Program: Benthic cover derived from analysis of images collected during stratified random surveys (StRS) across the Pacific Remote Island Areas"},"description":"The benthic cover data in this collection result from the analysis of images produced by benthic photo-quadrat surveys. These surveys were conducted along transects at stratified random sites across the Pacific Remote Island Areas since 2014 as a part of the ongoing National Coral Reef Monitoring Program's (NCRMP) Rapid Ecological Assessment (REA) surveys for corals and fish. Benthic cover data and the associated images are both included in this collection.\n\nA stratified random sampling (StRS) design was employed to survey the coral reef ecosystems throughout the U.S. Pacific regions. 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 (percent cover), frequency of occurrence, benthic community taxonomic composition and relative generic richness.\n\nBenthic habitat imagery were quantitatively analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill, 2006) software in 2014 and a web-based annotation tool called CoralNet (Beijbom et al. 2015) thereafter. In general, images were analyzed to produce three functional group levels of benthic cover: Tier 1 (e.g., hard coral, soft coral, macroalgae, turf algae, etc.), Tier 2 (e.g., Hard Coral = massive, branching, foliose, encrusting, etc.; Macroalgae = upright macroalgae, encrusting macroalgae, bluegreen macroalgae, and Halimeda, etc.), and Tier 3 (e.g., Hard Coral = Astreopora sp, Favia sp, Pocillopora, etc.; Macroalgae = Caulerpa sp, Dictyosphaeria sp, Padina sp, etc.).","distribution_titles":["CRCP Benthic Cover PRIAs","NCEI Dataset Landing Page","Granule

gathered using subsurface temperature recorders (STRs) that aid in the monitoring of seawater temperature variability at permanent coral reef sites in Puerto Rico as part of the NOAA Coral Reef Conservation Program\u2019s (CRCP's) National Coral Reef Monitoring Program (NCRMP). The high-accuracy temperature loggers (SBE56, SeaBird Electronics) are deployed on reefs for a period of three years. STRs are deployed along depth transects targeting 1, 5, 15, and 25 meters at ocean and climate change monitoring survey sites. Depth transects are located on the northern, southern, eastern, and western coasts of each target region. When a STR is recovered, typically another STR is deployed at the same location. Temperature data are collected in 5-minute intervals, and gaps in time-series (due to instrument failure or battery death) are manually padded with null values. STRs time-series data in this package were converted into coordinated universal time (UTC) from Eastern Standard Time (EST). For organizational purposes, temperature data files archived in this package are separated by region then by location. The temperature data provided in this collection were gathered from STRs deployed at existing long-term monitoring sites by the Acidification Climate and Coral Reef Ecosystems Team (ACCRETE), based at NOAA\u2019s Atlantic Oceanographic and Meteorological Laboratory (AOML). Because of delays caused by Covid-19, contractors were hired to swap sensors later in the cycle than normal in 2021/2022. This lead to the delayed deployment of many new sensors and caused gaps within the data.","distribution":[{"@type":"dcat:Distribution","accessURL":"https://doi.org/10.25921/p0tv-mw09","describedByType":"application/octet-stream","description":"Navigate directly to the URL for a descriptive web page with download links.","mediaType":"text/html","title":"NCEI Dataset Landing Page"},{"@type":"dcat:Distribution","accessURL":"https://www.ncei.noaa.gov/metadata/granule/geoportal/?from=0&size=10&esdsl=%7B%22query%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22query_string%22%3A%7B%22analyze_wildcard%22%3Atrue%2C%22query%22%3A%22fileid%3ANCRMP-STR-PR.*%22%7D%7D%5D%7D%7D%7D#searchPanel","describedByType":"application/octet-stream","description":"Search for data granules belonging to this collection (a granule is the smallest aggregation of data that can be independently described and retrieved).","mediaType":"text/html","title":"Granule Search"},{"@type":"dcat:Distribution","accessURL":"https://www.ncei.noaa.gov/archive/accession/0157633","describedByType":"application/octet-stream","description":"Documentation for NCRMP data","mediaType":"text/html","title":"https://www.ncei.noaa.gov/archive/accession/0157633"},{"@type":"dcat:Distribution","accessURL":"https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords","describedByType":"application/octet-stream","description":"Global Change Master Directory (GCMD). 2025.

Coral Reef Monitoring Program: Benthic cover derived from analysis of images collected from climate stations across the Mariana Archipelago"},"description":"The benthic cover data in this collection result from the analysis of images produced during benthic photo-quadrat surveys conducted along transects at climate stations and permanent sites across the Mariana Archipelago. These sites were identified by the Ocean and Climate Change team and the ongoing National Coral Reef Monitoring Program. Benthic habitat imagery were quantitatively analyzed using Coral Point Count with Excel extensions (CPCe; Kohler and Gill, 2006) software from 2010-2014 and a web-based annotation tool called CoralNet (Beijbom et al. 2015) from 2015 to present. In general, images are analyzed to produce three functional group levels of benthic cover: Tier 1 (e.g., hard coral, soft coral, macroalgae, turf algae, etc.), Tier 2 (e.g., Hard Coral = massive, branching, foliose, encrusting, etc.; Macroalgae = upright macroalgae, encrusting macroalgae, bluegreen macroalgae, and Halimeda, etc.), and Tier 3 (e.g., Hard Coral = Astreopora sp, Favia sp, Pocillopora, etc.; Macroalgae = Caulerpa sp, Dictyosphaeria sp, Padina sp, etc.). The imagery analyzed in order to produce the benthic cover data is also included in this collection.","distribution_titles":["CRCP Benthic Cover Climate Stations Pacific","NCEI Dataset Landing
