Seaglider SG012 collected temperature, salinity, and depth-averaged current data in the North Pacific Ocean's coastal waters. The autonomous underwater vehicle was deployed by the University of Washington and NOAA's National Centers for Environmental Information from November 16, 2005, to March 4, 2006. Data is accessible via NCEI Accession 0156521.
A NASA EarthData project investigating the sensitivity of West Antarctic ice streams D, C, and Whillans to tidal oscillations. The project deployed coordinated seismic and GPS instrument packages at 100-km spacing on Whillans and ice stream D to measure spatial extent over two lunar cycles. Data was collected by the organization SCIOPS and last updated on the platform in 2006.
A study from Antarctica's contaminated bay analyzes the impact of environmental variables and metal concentrations on benthic diatom communities. The research, conducted by SCIOPS and published in 2005, found that metal concentrations explained 45.9% of the variation in community composition, with tin alone accounting for 28%.
Delta carbon-13, delta carbon-14, and percent modern carbon measurements collected from discrete water samples and profiles in the North Atlantic Ocean, North Sea, and Norwegian Sea. The dataset was compiled by researchers from Aarhus University, Bangor University, Iowa State University, Queen's University Belfast, and the Waquoit Bay National Estuarine Research Reserve. Data collection spans over a century, from 1874 to 2005.
A shoreline shapefile for the Republic of Palau derived from visual interpretation of IKONOS satellite imagery between 2003 and 2006. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and Analytical Laboratories of Hawaii. It used a two-tiered classification system integrating geomorphologic reef structure and biological cover.
Seaglider SG016 collected temperature, salinity, and depth-averaged current data during a 9-month mission in the Labrador Sea from April 2005 to January 2006. The autonomous underwater vehicle was developed by the University of Washington and deployed by NOAA's National Centers for Environmental Information. This dataset captures physical ocean properties along a sawtooth glider trajectory.
Ground validation GPS point data was collected for benthic habitat mapping of the main eight Hawaiian Islands. The project was a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and private partners. Data collection was completed circa 2006 to support map preparation from IKONOS satellite imagery.
GPS field observations assess the thematic accuracy of coral reef habitat maps for the Main Eight Hawaiian Islands. The project involved 39 benthic habitat characterizations within UTM Zone 5. This cooperative effort was led by NOAA's National Centers for Coastal Ocean Science and partners, with data from 2006.
638 benthic habitat characterizations were collected via GPS field observations to validate coral reef habitat maps for the Main Eight Hawaiian Islands. This accuracy assessment data resulted from a cooperative project involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, and private partners. The dataset was published in 2006.
Tree-ring width data from the Blueberry River area in Canada's Northwest Territories, used for paleoclimate reconstruction. The chronology covers a period from 449 to -56 calendar years before present, indicating it extends through recent centuries. This archived study is provided by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology and was last updated in 2006.
500-meter dives are routinely performed by emperor penguins during foraging trips. The dataset addresses hypotheses on pressure tolerance, oxygen management, and prey selection for this Antarctic top predator. The project was conducted by SCIOPS with fieldwork in the Ross Sea, with data last updated in December 2005.
Seaglider SG005 collected temperature, salinity, and depth-averaged current data along sawtooth trajectories in coastal waters. This autonomous underwater vehicle, developed by the University of Washington, operated from June to November 2005. The dataset is archived by NOAA's National Centers for Environmental Information.
Hawaiian coastal waters were monitored by Seaglider SG021 from August to November 2005. The dataset contains physical measurements collected by an autonomous underwater vehicle developed by the University of Washington. Data was collected for NOAA's National Centers for Environmental Information.
Intertidal species inventory and quantitative organism count data were collected on the islands of Oahu and Maui. The project involved University of Hawaii researchers and a high school marine science class, with data gathered during annual site visits from 2001 through 2005. The dataset includes two primary data types: species lists and quantitative counts of key organisms.
The SPF Collection of Sao Paulo State is a collection of marine algae specimens exclusive to Sao Paulo State, deposited in the SPF Herbarium at Sao Paulo University. It has been curated by Prof. Eurico Cabral de Oliveira Filho and maintained as an important research collection since the early 1950s by Prof. Aylthon Brandao Joly. The collection system of classification follows Wynne (1985).
Hawaii coastal waters physical data were collected by the autonomous Seaglider SG020 during the Hawaii Ocean Timeseries from May to July 2005. The dataset includes measurements of temperature, salinity, and depth-averaged currents along a sawtooth trajectory. Data were collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.
Seaglider SG012 collected temperature, salinity, and depth-averaged current data during a mission from February to June 2005 in the North Pacific Ocean. The buoyancy-driven autonomous underwater vehicle was developed by the University of Washington and deployed by NOAA NCEI. Measurements were taken along a sawtooth trajectory through coastal waters off Washington and Oregon.
February to May 2005 data collected by an autonomous Seaglider vehicle during the Hawaii Ocean Timeseries. The dataset contains in-situ measurements of temperature, salinity, depth-averaged current, and other physical variables along a sawtooth trajectory through the water column. The data was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.
Seaglider SG014, an autonomous underwater vehicle, collected oceanographic data during a seven-month mission from September 2004 to April 2005. The dataset includes measurements of temperature, salinity, and depth-averaged currents along a sawtooth trajectory through the Labrador Sea. Data was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.
Seaglider SG015 collected temperature, salinity, and depth-averaged current data in the Labrador Sea from September 24, 2004, to March 31, 2005. The autonomous underwater vehicle executed sawtooth dive profiles, transmitting measurements in near real-time.
