GOES-8 satellite data provides reflectances used to determine high-resolution photosynthetically active radiation (PAR) over the Amazon rainforest. The dataset was produced by the SCIOPS organization and made publicly available through the Earth Science Information Partnership program. It was last updated in February 2001.
NOAA's Bioeffects Assessment Program applied a sediment quality triad approach to characterize chemical contamination, sediment toxicity, and benthic community structure across the Chesapeake Bay estuary system. Data includes measurements from a stratified probabilistic sampling design conducted in 1998, 1999, and 2001. The study aimed to define the extent and magnitude of biological effects associated with contaminants in the mainstem and major western subestuaries.
A 2000 USGS publication provides geospatial data on deep-seated landslide and debris flow susceptibility for rural western San Mateo County, California. The digital database includes 43 plotfiles and 12 ARC export files with hazard maps derived from slope data and previous geologic mapping. It also estimates possible costs for investigating and mitigating these hazards.
Anemometer height changes, averaging one per decade at stations with over 10 years of record, required homogenization for climatological analysis. NOAA's National Centers for Environmental Information processed these hourly wind observations from U.S. stations, with coverage expanding from a few stations in 1931 to nearly 1000 by 1985. The dataset's record ends in the year 2000.
8.2 meters of core were recovered from two holes at Allan Hills Trudge Valley, with an additional 18.67 meters from six holes at Table Mountain revealing a new fluvial gravel facies. The dataset also includes 15.9 meters of core from nine holes near Lake Vida's DVDP-6 site to assess diesel fluid contamination from 1972 drilling. Data was collected by the SCIOPS organization and last updated in December 2000.
A geospatial layer defines the coverage area of a sidescan sonar mosaic used to study benthic communities in Long Island Sound. The data was produced through a cooperative project involving the University of New Haven, the Connecticut Department of Environmental Protection, and the U.S. Geological Survey. It was published as part of USGS Open-File Report 00-304, with a last update recorded in 2000.
GPR data collected over two abandoned tip sites in Antarctica during the 2001/2002 Antarctic summer season. The data was gathered using a Ramac 250 MHz antenna and is stored in .rad and .rd3 formats. The dataset originates from the AU_AADC organization and was last updated on NASA's Earthdata platform in December 2000.
63 stations across 9 atolls or islands were sampled for benthic macroinvertebrate communities in October 2000. The assessment was conducted by NOAA personnel and analyzed by Barry A. Vittor & Associates, Inc. as part of the Northwest Hawaii Islands Coral Reef Assessment and Monitoring Program (NOWRAMP).
Australia's three Antarctic stations and Macquarie Island are the focus of this report on levelling observations. The dataset contains corrected results for thermal contraction, comparing measurements from fibreglass or aluminium staffs to invar staffs where possible. Matt King of the University of Tasmania prepared the report in June 2000 and revised it in November 2000.
A 2000 geospatial dataset documents the locations of fire hydrants at the Macquarie Island Station. The data was produced by the Australian Antarctic Data Centre (AU_AADC) and follows the SCAR Feature Catalogue format. It was last updated in September 2000.
A collection of environmental treaty texts compiled by NASA's Socioeconomic Data and Applications Center (SEDAC) in collaboration with Columbia University, UNEP, Tufts University, and other international partners. The collection was last updated on September 5, 2000. It likely contains the full text of international agreements related to environmental protection.
Casey Station fire hydrant locations are provided in this GIS dataset. The data is formatted according to the SCAR Feature Catalogue and was last updated in September 2000. The dataset originates from the Australian Antarctic Data Centre (AU_AADC).
Argentine Antarctic Institute and National University of Mar del Plata personnel collected this multidisciplinary data during three summer Antarctic campaigns. The project involved oceanographic, geological, cartographic, and engineering work in the Southern Ocean. Data collection concluded with the 1999-2000 campaign.
A 10-day time series of wave characteristics and temperatures was collected from a fixed Waverider buoy off Coastal Hawaii in the NE Pacific from 27 March 2000 to 05 April 2000. Wave characteristics include heights, periods, and directions. The data were collected by the University of Hawaii - Manoa (UHM) and are archived by NOAA NCEI.
South Victoria Land, Antarctica, contains two locations where glacial sediments were analyzed using micromorphology. The dataset likely contains results from Taylor Valley and Allan Hills to determine till types, glacial microstructures, and the character of past glaciation episodes. The data was contributed by SCIOPS and last updated on NASA's EarthData platform in January 2000.
Antarctica's Frio Shear Zone, a 4-kilometer-wide tectonic boundary in South Victoria Land, was investigated by SCIOPS. Fieldwork documented lithologies, structural orientations, and deformation phases across the boundary separating the Walcott and Dry Valleys blocks. The dataset was last updated in early 2000.
Hyperspectral imagery of the main eight Hawaiian islands, focusing on Oahu, was collected for coral reef and benthic habitat mapping. The AURORA system captured 72 spectral bands in the visible and near-infrared range at a 3-meter pixel resolution. This cooperative project was led by NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii, with data processed around the year 2000.
NOAA's project provides hyperspectral imagery of the main eight Hawaiian Islands, focusing on Maui, for coral reef and benthic habitat mapping. The dataset was created through a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data collection and processing occurred around the year 2000.
72 spectral bands in the visible and near-infrared range were collected by the AURORA hyperspectral imaging system at 3-meter pixel resolution. This dataset was developed through a cooperative project involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC to map coral reef habitats. The primary data collection and processing occurred around the year 2000.
NOAA's project developed coral reef mapping methods using hyperspectral and satellite imagery for the main eight Hawaiian Islands. The AURORA hyperspectral imaging system collected 72 spectral bands in the visible and near-infrared range with a 3-meter pixel resolution. This cooperative effort involved NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, with data processed around the year 2000.
