The Gulf of Mexico was the study area for this dataset, which contains physical, chemical, and other marine data collected from the R/V GYRE. Data were gathered using trawl nets, SeaWiFS satellite instruments, and other tools from August 1, 1999, to August 1, 2002. Texas A&M University submitted the data as part of the Deepwater project, and it is archived by NOAA's National Centers for Environmental Information.
Bacterial, physical, and nutrient data were collected from bottle and CTD casts during a 25-day cruise from April 26 to May 20, 2002. Oregon State University researchers gathered this data off the Oregon coast from the R/V WECOMA. The dataset includes CTD parameters like temperature and salinity alongside bottle measurements of nutrients and bacterial activity.
Temperature and relative humidity sensor data were collected inside Antarctica's historic Mawson's Huts to measure deterioration processes. The dataset includes fields for site, latitude, distance from sea, days exposed, corrosivity, mass loss, and thermocouple profiles. It was published by the Royal Society of Tasmania and last updated in 2002.
Contamination data from McMurdo Sound, Antarctica, details concentrations of total hydrocarbons, PCBs, and PAHs in marine sediments, bivalves, and sponges. The dataset compares levels near scientific bases like Scott Base and McMurdo Station against less contaminated reference sites. It was published by SCIOPS and last updated in March 2002.
A 10-metre cell size Digital Elevation Model (DEM) of Heard Island was created by a contractor for the Australian Antarctic Data Centre. The model was generated from RADARSAT images acquired on February 17 and March 13, 2002, and merged with a prior 1997 stereoscopic DEM. The dataset includes the final DEM, a rectified RADARSAT image, generated contours, and technical reports.
A digital elevation model of Macquarie Island with a five-metre grid interval, referenced to mean sea level. The dataset was improved by Dr Michael Roach of the University of Tasmania and provided to the Australian Antarctic Data Centre in January 2006. The original data is from 2002.
Accuracy Assessment point data was created to validate benthic habitat maps derived from three distinct remote sensing platforms: aerial photography, hyperspectral, and IKONOS satellite imagery. The project was a cooperative effort between NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. Data generation was completed around the year 2000.
Accuracy Assessment point data were generated to evaluate benthic habitat maps created from three distinct remote sensing sources: color aerial photography, hyperspectral, and IKONOS satellite imagery. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC. Data collection and analysis were completed around the year 2000.
2000-era point data generated to assess the accuracy of benthic habitat maps for Oahu, Hawaii. The data was created by a partnership including NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. It compares maps derived from aerial photography, hyperspectral, and IKONOS satellite imagery.
2000 data points for assessing the accuracy of benthic habitat maps for the Main Hawaiian Islands, specifically Molokai. The dataset was created through a collaboration between NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. It was generated to evaluate maps derived from aerial photography, hyperspectral, and IKONOS satellite imagery.
1980-2001 annual estimates of physical exposure to drought, measured as the expected average annual population exposed. The dataset was modeled by UNEP/GRID-Europe for the Global Assessment Report on Risk Reduction, integrating precipitation, Standardized Precipitation Index, and 2010 population data.
IKONOS satellite imagery was purchased to support coral mapping activities in the Pacific Islands. The dataset includes one-meter panchromatic and four-meter multispectral data for Tutuila Island, processed to minimize atmospheric and water column effects. This cooperative project involved the National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii, with data last updated in 2002.
IKONOS satellite imagery was purchased and processed for coral mapping activities in American Samoa. The dataset includes one-meter panchromatic and four-meter multispectral data for Swains Island. The imagery was processed to minimize atmospheric and water column effects to support coral health and time series analysis.
American Samoa's Rose Atoll is covered by one-meter panchromatic and four-meter multispectral IKONOS satellite imagery. The data was purchased and processed by a cooperative effort involving NOAA's National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii to support coral reef mapping and GIS projects. Imagery was processed to minimize atmospheric and water column effects for habitat delineation.
NOAA's National Centers for Coastal Ocean Science and partners acquired IKONOS satellite imagery to support coral reef mapping in the Pacific Islands. The collection includes one-meter panchromatic and four-meter multispectral data for American Samoa's Manua Islands, processed to reduce atmospheric and water effects. Data was published in 2002.
Oregon State University submitted this collection of salinity and water temperature measurements for the coastal waters of Washington and Oregon. Data were gathered using a conductivity sensor and temperature probe over a ten-month period from March to December 2001. The dataset is archived by NOAA's National Centers for Environmental Information.
Wake Forest University researchers tracked nesting Waved Albatrosses via satellite telemetry from Punta Cevallos, Isla Española in the Galápagos archipelago. The data covers two breeding seasons in 2000 and 2001, with Platform Transmitter Terminals attached to birds using a tape method. Tracking was conducted via the Argos System satellites, with varying transmitter duty cycles between the two years.
17 moorings collected current meter data in Lake Superior from 1998 to 2001. The Keweenaw Interdisciplinary Transport Experiment in Superior (KITES) project was conducted by the University of Washington and University of Minnesota. Data is archived by NOAA's National Centers for Environmental Information.
Static and kinematic GPS data collected on the Amery Ice Shelf using Leica 399 receivers. Additional GPS data were collected at Beaver Lake, Hamm Peak, Moushino Is., New Year Nunataks, Jetty Peninsula, and Else Platform. The dataset, provided in compressed RINEX format, was last updated by AU_AADC on 2001-03-31.
Core samples from the Floridan Aquifer were collected, prepared as slabs, and examined for lithology. The dataset was compiled by CEOS_EXTRA and last updated in April 2001. The specific volume of samples and number of observations are not documented.
