Davis Station Fire Hydrants and Fire Hoses GIS Dataset contains geospatial data on fire hydrant positions at Australia's Davis research station in Antarctica. The dataset was published by the Australian Antarctic Data Centre (AU_AADC) and follows the SCAR Feature Catalogue standards. Its last recorded update was in June 2013.
Physical oceanographic measurements were collected by a Slocum glider unit_251 deployed by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction. Data spans a 24-day period from May 8 to May 31, 2013, in the coastal waters of Washington and Oregon. The dataset was archived by NOAA's National Centers for Environmental Information after processing by the IOOS National Glider Data Assembly Center.
U-Pb zircon geochronological data for Ferrar Dolerite and Kirkpatrick Basalt rocks from the Transantarctic Mountains. The data were collected by David H. Elliot and Thomas H. Fleming over Antarctic field seasons between 1966 and 2011, with geochronological analysis by Seth Burgess and Samuel Bowring of MIT. These data are intended to be linked with concurrent geochemical data.
A geospatial point dataset maps the positions of fire hydrants and fire hose reels at Australia's Mawson research station in Antarctica. It was compiled by the Australian Antarctic Data Centre (AU_AADC) and last updated in May 2013. The data conforms to the SCAR Feature Catalogue for standardization.
Seven microsatellite markers provide genotypes for three Antarctic sea urchin species of the genus Abatus. The data was collected by the Australian Antarctic Data Centre from individuals at five near-shore sites around Davis Station in East Antarctica. The dataset was last updated in March 2013.
NCEI Accession 0137964 contains physical trajectory profile data collected by a Rutgers University glider (ru23) in the Mid-Atlantic Bight. The dataset includes measurements of temperature, salinity, conductivity, and density from a deployment spanning March 5 to March 23, 2013. Data were aggregated and preserved by NOAA's National Centers for Environmental Information after processing by the IOOS National Glider Data Assembly Center.
Oceanographic and surface meteorological data were collected from an in-situ moored station in the Northeast Pacific Ocean. The data span from February 2009 to March 2013. Humboldt State University collected the data, which were assembled and submitted by the Central and Northern California Coastal Ocean Observing System (CeNCOOS).
An R model estimates species relative abundance from presence-absence data. The Australian Antarctic Data Centre provides the code, demonstrated with Antarctic moss data. The model was last updated in 2013.
January 2013 data from a Rutgers University glider deployment in the Southern Ocean. The dataset contains physical oceanographic measurements, including temperature, salinity, conductivity, and density, collected for long-term ecological research. Data were assembled by the IOOS National Glider Data Assembly Center and archived by NOAA's National Centers for Environmental Information.
Oxygen isotopic ratio measurements from sea ice, brine, snow, and seawater collected during the SIPEX II voyage in Antarctica. Data includes sampling station names and dates, with analysis precision of ±0.02 parts per thousand. The dataset was collected by the Aurora Australis in 2012 and analyzed at Hokkaido University.
Slocum glider RU23 captured sub-surface ocean conditions before and during Hurricane Sandy's landfall in 2012.
