Gulf of Alaska measurements from the Seaglider SG011 autonomous underwater vehicle, deployed from December 30, 2004, to February 2, 2005. The dataset contains physical oceanographic data collected along a sawtooth trajectory through the water column. It was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information (NCEI).
Seaglider SG012 collected temperature, salinity, and depth-averaged current data along sawtooth trajectories in the North Pacific Ocean. This buoyancy-driven autonomous underwater vehicle was deployed by the University of Washington for NOAA NCEI. The mission lasted from December 23, 2004, to January 25, 2005.
1988 to 2005 oceanographic profiles of temperature and salinity collected via Conductivity, Temperature, Depth (CTD) instruments in the North Atlantic and North Pacific oceans. The data was gathered by the Sea Education Institution's Sea Semester Program and is archived by NOAA's National Centers for Environmental Information (NCEI).
May and August 2005 data collection characterizes chemical contamination in southwest Puerto Rico's marine environment. The dataset includes analysis of 71 sediment samples for total organic carbon and 43 sites for a broad suite of contaminants, plus coral tissue from eight sites. It was produced by NOAA's National Status and Trends Bioeffects Program to establish baseline data.
NOAA_NCEI provides a personal geodatabase containing raster images of chlorophyll concentrations in the Gulf of Maine. The dataset is a composite of satellite-derived data from 1997 to 2005, processed into seasonal and monthly mean or median images. Images have been reprocessed to remove land and no-data values, with chlorophyll values expressed in micrograms per liter.
Seaglider SG002 collected temperature, salinity, depth-averaged current, and other physical oceanographic data along sawtooth dive trajectories. The autonomous underwater vehicle was deployed by the University of Washington for a mission lasting from December 23 to December 30, 2004. Data is archived by NOAA's National Centers for Environmental Information.
Oceanographic data collected by an autonomous Seaglider underwater vehicle during a mission in the Gulf of Alaska. The dataset includes measurements of temperature, salinity, and depth-averaged currents along a sawtooth trajectory. The mission was deployed by NOAA NCEI from August to December 2004.
Seasonal composites from 1998 onward show chlorophyll concentrations in the Gulf of Maine. The raster images were processed by NOAA_NCEI to remove land and no-data values and calculate real-world values in micrograms per liter. The dataset was last updated in 2005.
Seaglider SG005 collected temperature, salinity, depth-averaged current, and other physical data along sawtooth trajectories in the North Pacific Ocean. The autonomous underwater vehicle was deployed by the University of Washington and its data is archived by NOAA NCEI. Measurements were recorded from August 30 to December 23, 2004.
A detailed hazard assessment was conducted in October and November 2004 for the Little Mill campground in American Fork Canyon, Utah, following a preliminary review. The U.S. Geological Survey performed this work at the request of the U.S. Forest Service after two fatal rock-fall incidents in the mid-1990s at a nearby site. The report describes the methodology, results, and conclusions from the assessment, which used a combination of field- and aerial-based methods.
Physical oceanographic data collected by an autonomous Seaglider vehicle during a nine-day mission in November 2004. The dataset includes measurements of temperature, salinity, and depth-averaged current along a sawtooth trajectory through the water column. Data was collected by the University of Washington and archived by NOAA NCEI.
The US Environmental Protection Agency's 2004 National Coastal Assessment surveyed estuarine resources in American Samoa. It includes water quality measurements from in-field observations and lab analyses, plus sediment chemistry and grain data from laboratory examinations. The survey sampled 49 stations across the islands of Tutuila, Aunu'u, Ofu, Olosega, and Ta'u during April and August 2004.
2004-03-17 to 2004-08-21 data from an autonomous Seaglider vehicle deployed in the Gulf of Alaska. The dataset contains physical oceanographic measurements, including temperature and salinity, collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.
North Pacific Ocean coastal waters of Washington and Oregon contain physical oceanographic data collected by an autonomous Seaglider vehicle. The dataset, archived by NOAA's National Centers for Environmental Information (NCEI), captures measurements from a single deployment spanning June 24 to July 28, 2004. The Seaglider SG005 was developed by the University of Washington.
Physical data collected by Seaglider SG002, an autonomous underwater vehicle developed by the University of Washington. The dataset contains measurements from a deployment in the coastal waters of Washington and Oregon from January to June 2004. Data is archived by NOAA's National Centers for Environmental Information.
Chemical assessment data documents heavy metal concentrations in soil and leachates from an abandoned waste disposal site in Antarctica's Thala Valley. The dataset covers two summer seasons (2002/2003 and 2003/2004) for pre-cleanup assessment and post-remediation validation. It was collected by the Australian Antarctic Data Centre.
Seaglider SG004 collected temperature, salinity, and depth-averaged current data during a 4-month mission in the Labrador Sea. This autonomous underwater vehicle from the University of Washington performed sawtooth dives from October 2003 to February 2004. The National Oceanic and Atmospheric Administration's National Centers for Environmental Information archives this dataset.
MODIS/Aqua Net Evapotranspiration Yearly L4 Global 500m SIN Grid V006 provides yearly composites of evapotranspiration and latent heat flux data. The dataset was produced by LPCLOUD using an algorithm based on the Penman-Monteith equation, incorporating MODIS remote sensing and meteorological reanalysis data. This specific version was decommissioned on July 31, 2023.
Physical oceanographic data collected by an autonomous Seaglider vehicle during a mission in the Labrador Sea. The dataset contains measurements of temperature, salinity, depth-averaged currents, and other quantities along a sawtooth trajectory. The mission was deployed by NOAA NCEI from October 2003 to January 2004.
NOAA's National Status and Trends program collected data on sediment contamination, toxicity, and benthic community structure in Florida's St. Lucie Estuary from 2001 to 2004. The study employed a sediment quality triad approach with a probabilistic sampling design. This summary database was created by NOAA's National Centers for Environmental Information (NCEI) as part of a prototype for a national data portal.
