Over 296,000 adult fish specimens and 6.9 million early life history specimens are cataloged in this collection from the University of Washington. The adult collection represents 4,054 species, with 75% being marine fishes from the North Pacific and Bering Sea. The early life history collection grew significantly from 1965 to 1998 through efforts by the National Marine Fisheries Service and other institutions.
The National Geochemical Data Base contains more than two million records for samples collected in the United States and foreign countries. It includes data from USGS programs like NMRAP and the DOE's NURE HSSR, as well as RASS data, compiled from approximately 1996 onward. Samples of stream sediment, soil, rock, water, and vegetation were analyzed using techniques like emission spectroscopy, neutron activation, and x-ray emission.
34 oceanographic stations were sampled across the Weddell Sea, including the Kapp Norvegia, Hilltop, Austasen, and Orleans Canyon zones. The campaign collected vertical profiles of temperature, salinity, and nutrients, 31 sediment samples, and current meter data recorded every 5 minutes over 9 days. It was conducted by the organization SCIOPS, though the specific year is not provided.
MODIS/Terra satellite data provides two primary vegetation indices, NDVI and EVI, at a 500-meter spatial resolution for global land monitoring. The algorithm selects the best pixel value from all acquisitions within a 16-day period based on low clouds, low view angle, and highest index value. This Version 6.1 product is generated by the LPCLOUD organization using NASA's Terra satellite sensor.
MODIS/Terra Vegetation Indices 16-Day L3 Global 1km SIN Grid V061 provides per-pixel vegetation index values at 1 kilometer spatial resolution. The dataset includes two primary vegetation layers, Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI), along with four reflectance bands and quality assurance layers. It is produced by LPCLOUD/NASA from MODIS Terra sensor data.
MODIS/Terra Vegetation Continuous Fields V061 provides global annual estimates of surface vegetation as gradations of three ground cover components: percent tree cover, percent non-tree cover, and percent non-vegetated. The LPCLOUD product offers a continuous, quantitative portrayal at 250-meter pixel resolution. Each annual period begins around day of year 65.
MODIS/Aqua satellite data provides two primary vegetation indices, NDVI and EVI, at a 500-meter spatial resolution aggregated over 16-day periods. The dataset includes reflectance bands, quality assurance layers, and observation metadata. It is produced by LPCLOUD using NASA's Aqua satellite sensor.
MODIS/Aqua Vegetation Indices 16-Day L3 Global 1km SIN Grid V061 provides two primary vegetation layers: Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). The dataset includes reflectance bands and quality assurance layers at 1-kilometer spatial resolution, produced by LPCLOUD from NASA's Aqua satellite.
Late summer acoustic survey data on pelagic fish abundance and size distribution across five Wisconsin lakes. The dataset is produced by the North Temperate Lakes Long-Term Ecological Research site, affiliated with the Center for Limnology at the University of Wisconsin, Madison. Data collection involves running transects on two nights and two days per lake using a Simrad 70 kHz echosounder.
Long-Term Ecological Research data contains counts of benthic macroinvertebrates collected from seven primary lakes in Wisconsin's Northern Highland Lakes District. The dataset currently includes identified and counted samples from Trout Lake (1981-1985) and Crystal Lake (1982, 1985, 1987). The North Temperate Lakes site, affiliated with the University of Wisconsin-Madison's Center for Limnology, gathered this data using modified Hester-Dendy samplers.
Long-term ecological research data on crayfish populations in seven primary study lakes within Wisconsin's Northern Highland Lakes District. The dataset includes species-level counts from baited trap surveys, with detailed annual surveys for the invasive species Orconectes rusticus in Trout Lake. Data collection was initiated in 1972 and is maintained by the Center for Limnology at the University of Wisconsin, Madison.
Sediment deposition data is collected from three primary study lakes in Wisconsin using sediment traps deployed during ice-free periods. The dataset includes mass deposition rates and constituent analyses for carbon, nitrogen, phosphorus, and silica. The North Temperate Lakes site, affiliated with the University of Wisconsin-Madison's Center for Limnology, gathers this data as part of the Long-Term Ecological Research Program.
Planktonic data includes chlorophyll a, phytoplankton primary production, and zooplankton species abundance from seven primary study lakes in Wisconsin. Measurements are conducted concurrently with physical and chemical limnology studies by the North Temperate Lakes LTER site, affiliated with the University of Wisconsin-Madison's Center for Limnology. The data supports long-term ecological research in a region with one of the world's highest concentrations of lakes.
Fish and benthic composition data from La Parguera, Puerto Rico (2001-present) and Guanica, Puerto Rico (2011). NOAA's Center for Coastal Monitoring and Assessment Biogeography Branch conducted this monitoring to support spatial management decisions and establish data collection standards for the National Coral Reef Monitoring Program. Standardized protocols were used to quantify fish, macro-invertebrates, and benthic parameters at randomly selected sites stratified by nearshore habitat maps.
NOAA's Biogeography Branch conducted standardized field surveys across nearshore habitats in Puerto Rico to quantify reef fish and macro-invertebrate populations. The data links species distribution and abundance to underlying benthic composition and habitat maps from 2001. This effort supports the National Coral Reef Monitoring Program's goal to establish data standards for U.S. Caribbean territories.
Jornada Long Term Ecological Research Network data documents changes in soil resource distribution as an index of desertification in semiarid lands. The project studies over 100,000 hectares of the Chihuahuan Desert in southern New Mexico, funded by the National Science Foundation. Research focuses on the hypothesis that vegetation change from grassland to shrubland creates patchy 'islands of fertility' under shrubs.
2019 to present laser ranging data from the GEDI instrument on the International Space Station. The Level 2B product extracts biophysical metrics like canopy cover and Plant Area Index from waveforms, with data provided by NASA's LPCLOUD. Data acquisition was suspended from March 2023 to April 2024.
Laser ranging observations from 2019 to 2024, with a hiatus from March 2023 to April 2024, characterize 3D ecosystem structure. The Global Ecosystem Dynamics Investigation instrument on the ISS provides geolocated waveform data for eight beams across latitudes between 51.6° N and 51.6° S. Data products are created and distributed by the LPCLOUD organization.
A 1976-initiated agricultural experiment compares four tillage systems—moldboard plough, chisel plow, ridge-plant, and no-till—on continuous and rotated corn and soybean plots. Measurements include yearly crop yield, total dry matter offtake, and detailed soil properties like pH, phosphorus, potassium, and organic matter content sampled at multiple depths. The site, a Chalmers silty clay loam, has a documented land-use history extending back to native prairie before 1880.
ECOSTRESS satellite data provides global measurements of plant Water Use Efficiency (WUE), the ratio of carbon absorbed to water released. The dataset is derived from the Breathing Earth System Simulator (BESS) Gross Primary Production and Priestley-Taylor Jet Propulsion Laboratory Soil Moisture transpiration estimates. It is produced by LPCLOUD from the ECOSTRESS instrument on the International Space Station, with data collection starting in 2018.
