AU_AADC collected biological and environmental data to assess the impact of untreated sewage effluent discharged from Davis Station into the nearshore marine environment since 2005. The dataset supports evaluating wastewater properties, environmental dispersal characteristics, and ecological impacts to guide treatment infrastructure upgrades. Data collection concluded around March 2010.
Australian Antarctic Division data assesses the environmental impact of sewage outfall at Davis Station. The dataset supports decisions on wastewater treatment upgrades to meet Antarctic Treaty standards. It was collected for a project culminating in a 2010 assessment.
Data from a 2005-2010 assessment of untreated wastewater discharge at Australia's Davis Station in Antarctica. The dataset contains chemical and environmental measurements to evaluate pollution levels and guide treatment infrastructure upgrades. It was produced by the Australian Antarctic Data Centre (AU_AADC) and last updated in March 2010.
Untreated wastewater has been discharged at Davis Station since 2005 following the removal of old treatment infrastructure. The Australian Antarctic Data Centre produced this assessment in 2010 to guide the selection of a new wastewater treatment facility and evaluate environmental impacts.
Animations visualize the seasonal melt of sea ice and resulting chlorophyll-a blooms in East Antarctica from the 1997/98 to 2009/10 seasons. Data combines sea ice concentration from SMMR-SSM/I and AMSR-E satellites with chlorophyll-a measurements from SeaWiFS and MODIS sensors. The dataset was compiled by the Australian Antarctic Data Centre and last updated in April 2010.
A 2010 interdisciplinary study investigated the interactive effects of iron, light, and carbon dioxide on diatom and Phaeocystis Antarctica blooms in the Ross Sea. The project, led by AMD_USAPDC, combined field surveys with shipboard experiments during spring and summer seasons. It aimed to identify factors controlling phytoplankton distribution and their role in biogeochemical cycles.
A 10-year record from September 1999 to October 2009 provides monthly global maps of wind and wind stress fields. The dataset consists of twelve variables derived from NASA QuikSCAT scatterometer measurements using harmonic analysis. It was created by Risien et al. and archived by SCIOPS.
North Atlantic Ocean data collected by Seaglider SG005 during a 71-day mission from August to November 2009. The dataset contains measurements of temperature, salinity, and depth-averaged current along the vehicle's sawtooth trajectory. It was collected by the University of Washington and archived by NOAA's National Centers for Environmental Information.
A 10-meter cell size Digital Elevation Model (DEM) of Heard Island was created from TerraSAR-X stereo pairs acquired between October 31 and November 14, 2009. The Australian Antarctic Data Centre commissioned the work, which includes accuracy assessments and auxiliary files.
Shallow (<100 m) ice cores from Victoria Land, East Antarctica, collected along a traverse from Taylor Dome to the South Pole. The project, supported by AMD_USAPDC and last updated in 2009, aims to extend the Antarctic climate record using stable isotopes of water (18-O/16-O and D/H ratios) as temperature proxies. Age-depth relationships are determined through stable isotopes, visual stratigraphy, and seasonal chemical signatures.
Physical oceanographic measurements were collected by a Slocum glider unit_092 deployed by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction. The dataset captures a single deployment from September 1 to September 4, 2009, in the coastal waters of Washington and Oregon. Data were archived by NOAA's National Centers for Environmental Information after processing by the IOOS National Glider Data Assembly Center.
Physical oceanographic measurements from a Slocum glider deployment in coastal waters from July 23 to August 21, 2009. The data, including temperature, salinity, conductivity, and density, were collected by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction for the SATURN observatory. It was archived by NOAA's National Centers for Environmental Information.
North Atlantic Ocean data from the Iceland Faroe Ridge collected by Seaglider SG016, an autonomous underwater vehicle. The dataset contains physical measurements like temperature and salinity from a mission spanning June 5 to July 31, 2009. It is archived by NOAA's National Centers for Environmental Information (NCEI).
Physical trajectory profile data from glider unit_092 deployed by Oregon Health & Science University's Center for Coastal Margin Observation & Prediction. The dataset contains measurements of physical oceanographic properties from a deployment in the coastal waters of Washington/Oregon between June 10 and July 3, 2009. Data were gathered as part of the CMOP observatory SATURN, funded by NOAA and NSF, and archived by the National Centers for Environmental Information.
Seaglider SG103 collected temperature, salinity, and depth-averaged current data in the North Atlantic Ocean from February 23 to June 5, 2009. The dataset, archived by NOAA's National Centers for Environmental Information (NCEI), originates from a buoyancy-driven autonomous underwater vehicle developed by the University of Washington. Measurements were taken along a sawtooth trajectory through the water column during a multi-month mission.
Ocean Station PAPA in the North Pacific Gulf of Alaska collected physical ocean data via a Seaglider SG120 autonomous underwater vehicle from August 30, 2008, to June 4, 2009. The dataset, archived by NOAA's National Centers for Environmental Information (NCEI), contains measurements from the vehicle's sawtooth gliding trajectory. Seagliders are buoyancy-driven vehicles developed by the University of Washington for long-duration, long-range scientific missions.
