Coastal Marten Extant Population Areas delineates four extant population areas for the coastal marten (Martes caurina) in coastal Oregon and northern coastal California. The dataset was created by the U.S. Fish and Wildlife Service using verifiable marten detections since 1980, as described in a 2018 species status assessment report. It represents the spatial boundaries of areas where likely self-sustaining populations exist.
June 1995 animations model a 1.5-hour supercell evolution and visualize fractal-like lightning branch structures from a severe storm in West Texas. Data were collected by researchers as part of the Verification of the Origins of Rotation in Tornados EXperiment (VORTEX) project spanning the spring seasons of 1994 and 1995. Scientists at the National Severe Storms Laboratory and the University of Oklahoma continue to analyze this data to improve 3D supercell models and lightning simulations.
Monitoring data collected from 2003 to the present for coral reef ecosystems in St. John, US Virgin Islands. The dataset is part of a study by NOAA's Center for Coastal Monitoring and Assessment to assess reef fish, macro-invertebrates, and water quality. It is used to establish a knowledge base for marine management decisions and zoning efficacy.
Fish and benthic composition data collected for St. John, US Virgin Islands since 2001 by NOAA's Center for Coastal Monitoring and Assessment. The dataset likely contains species distribution, abundance, size, and associated benthic parameters from stratified random sampling. It is intended to support spatial management decisions and is part of the National Coral Reef Monitoring Program.
NOAA's Biogeography Branch has conducted research in the US Virgin Islands since 2001 using Rapid Habitat Assessment surveys. The dataset likely contains quantified information on reef fish abundance, macro-invertebrate populations, and benthic composition parameters collected at randomly selected sites. The intent is to support spatial management decisions and establish monitoring standards for coral reefs.
NOAA's Center for Coastal Monitoring and Assessment has conducted standardized surveys of reef fish, macro-invertebrates, and benthic composition in Puerto Rico and the US Virgin Islands since 2000. This 2011 dataset from St. John, USVI, supports spatial management decisions by relating species distribution to underlying habitat maps and bathymetry. The work is part of a long-term effort to establish data collection standards for the National Coral Reef Monitoring Program.
NOAA's Center for Coastal Monitoring and Assessment Biogeography Branch collected these water quality data to assess and monitor coral reef ecosystems in the US Virgin Islands and Puerto Rico. The work began in 2003 and aims to spatially characterize reef fish and macro-invertebrate populations, relate them to in-situ water quality and habitat parameters, and establish a knowledge base for marine management decisions. Data collection follows standardized protocols across the US Caribbean, using stratified random sampling based on NOAA's nearshore benthic habitat maps.
SOMBASE contains distribution records for marine molluscs in the seas around Antarctica. The database includes over 1,400 species from more than 3,350 locations, based on published records and British Antarctic Survey data. SCAR-MarBIN serves 7,695 records from this biogeographic database.
The Senegal Desertification Hazard model was developed for the UNEP/FAO/ESRI Database for Africa. It is a raster dataset in IDRISI format, created in April 1987 using an FAO-provided model that considered soil constraints, wind and water action, salinization, and population pressure. The data was rasterized by GRID-Geneva with cell sizes of approximately one and four square kilometers.
Department of the Interior packaged outputs from a secondary landscape connectivity model for the coastal marten. The data includes Extant Population Areas, least-cost paths, and least-cost corridors connecting these populations, generated using Linkage Mapper. The packaged data layers were last updated on March 4, 2026.
The World Conservation Monitoring Centre (WCMC) maintains a plant taxonomy database covering 82,500 species, subspecies, and varieties of vascular plants worldwide. This taxon-based information is linked to 145,000 distribution records and 17,000 data source records. The data is managed using the BG-BASE database application, which has been in use since 1985.
Three psychrotrophic bacterial strains isolated from Antarctic coastal marine environments underwent polyphasic taxonomic analysis. SCIOPS conducted the study, which included DNA-DNA hybridization, fatty acid profiling, and 16S rRNA gene sequencing. The isolates were classified within the genus Shewanella.
U.S. Fish and Wildlife Service Region 5 provides boundary layers for the Monomoy National Wildlife Refuge in Massachusetts. Data was digitized from status maps and orthophotos at a scale of 1:24,000, with a major recompilation completed on May 25, 2000. The dataset serves as a spatial reference for refuge boundaries within GIS applications.
Northern Gulf of America seabird survey effort data from aerial transects flown between 2018 and 2023. The dataset was generated by the Bureau of Energy Management's Gulf of America Marine Assessment Project for Protected Species (GoAMAPPS) and the U.S. Fish and Wildlife Service. Surveys covered from the USA-Mexico border near Brownsville, Texas, to Key West, Florida, extending 50 to 100 miles offshore.
Ice duration data records the day of freeze-up and thaw for seven primary lakes in Wisconsin's Northern Highland Lakes District. Observations are made daily during freeze and thaw periods by the North Temperate Lakes site affiliated with the University of Wisconsin-Madison's Center for Limnology. The study area covers approximately 10,000 square kilometers with one of the world's highest concentrations of lakes.
Meteorological measurements recorded at one-minute intervals provide air temperature, humidity, wind, radiation, soil temperature, and precipitation data for the Trout Lake area. Data are averaged to hourly and daily periods and collected by the North Temperate Lakes Long-Term Ecological Research site, affiliated with the University of Wisconsin-Madison's Center for Limnology. The site focuses on lake ecosystems within Wisconsin's Northern Highland Lakes District.
Long-term measurements of lake evaporation from Sparkling Lake, Wisconsin, calculated using energy budget and mass transfer techniques. Data includes hourly-averaged micrometeorological parameters like relative humidity, air temperature, wind velocity, water temperature, and radiation, collected via an instrumented raft and shore station. The dataset is maintained by the North Temperate Lakes (NTL) site, affiliated with the Center for Limnology at the University of Wisconsin, Madison.
Long-term ecological data from seven primary study lakes in Wisconsin's Northern Highland Lakes District. The dataset contains counts and derived density measurements of pelagic macroinvertebrates, collected via vertical net tows. Research is conducted by the North Temperate Lakes site, affiliated with the Center for Limnology at the University of Wisconsin-Madison.
Measurements of water movement through two landscape transects of approximately 12% slope at the Kellogg Biological Station. Data collection employs neutron probe access tubes to 1.5 m depth and time domain reflectometry probes inserted into soil horizons. The station, administered by Michigan State University since 1929, supports interdisciplinary research in ecology, agriculture, and natural resources.
Spatial variability data for a 45-hectare soybean field was collected during the 1988 growing season. The dataset contains 400-600 sample points with measurements across geomorphological, soil chemical, soil biological, plant, and insect characteristics. Research was conducted at the W.K. Kellogg Biological Station, a facility administered by Michigan State University.
