Microbial community structure data from a 2006 sub-Antarctic soil experiment investigating hydrocarbon degradation under different oxygen regimes. The Australian Antarctic Data Centre collected measurements at the experiment's start and after 4, 8, and 12 weeks of incubation. This work was part of AAS projects 2672 and 1163.
Casey Station hosted a five-year field experiment from 2001 to 2006 testing the effects of four petroleum hydrocarbons on marine sediment ecosystems. The Sediment Recruitment Experiment 4 deployed trays containing contaminated sediments at O'Brien Bay-1, with samples collected at intervals from 5 weeks to 5 years. Analyses included sediment chemistry, microbial, meiofaunal, macrofaunal, and diatom communities, comparing treatments like synthetic lubricating oils and Special Antarctic Blend diesel fuel.
Sediment Recruitment Experiment 4 (SRE4) was a 5-year field experiment at Casey Station from 2001 to 2006. It tested the effects of four different hydrocarbons on marine sediment ecosystems, with samples collected from replicate trays at intervals from 5 weeks to 5 years. Analyses included sediment hydrocarbon chemistry, microbial, meiofaunal, macrofaunal, and diatom communities.
SCIOPS collected soil samples from the western Wright Valley near Lake Vanda in January 2006. The data consist of lab-based measurements including bulk density, texture, moisture, organic carbon, nitrogen, chlorophyll, and CO2 flux under controlled conditions. At the time of the abstract, data compilation and statistical analysis were not complete, and subsamples were stored for future microbial diversity analysis.
Nutrient subsidy experiments in the Garwood Valley tested the hypothesis that McMurdo Dry Valley soils rely on external carbon and nitrogen sources. The dataset includes pre- and post-treatment soil samples analyzed for microbial respiration, community composition, and chemical properties across three field seasons from 2001 to 2005. Data collection was organized by SCIOPS and is hosted on NASA EarthData.
Soil samples were gathered from the upper Garwood Valley in January of 2002, 2003, 2005, and 2006. The dataset includes field and lab measurements such as bulk density, moisture, temperature, organic carbon, nitrogen, chlorophyll, and CO2 flux under varied conditions. Results indicate high rates of soil respiration and potential carbon and nitrogen limitations, with subsamples stored for future microbial analysis.
Soil samples from 2004 and 2005 around Casey Station and nearby Antarctic regions were analyzed for bacterial polyhydroxyalkanoate (PHA) production. Researchers from the Australian Antarctic Data Centre isolated and screened bacteria, identifying PHA-producing Janthinobacterium and Pseudomonas species and characterizing PHA types from different carbon sources. The dataset includes bacterial isolates with their closest GenBank homology based on 16S rRNA gene sequences.
Sediment and soil samples from two consecutive Antarctic summers reveal a drastic annual increase in surface sediment PAH concentrations, from a maximum of 312 ng g-1 in 2004 to 1908 ng g-1 in 2005. Researchers from SCIOPS measured concentrations of two- and three-ring PAHs like methylnaphthalene and phenanthrene near Jubany Station in the South Shetland Islands. The dataset captures this temporal shift, linking PAH mobilization to precipitation and permafrost thaw.
BP's 2006 Statistical Review details global production of oil, natural gas, and coal through 2005. The review includes data back to 1965, providing a long-term perspective on energy trends. British Petroleum compiled this annual report, with the 2006 edition covering the year 2005.
Experimental data from a study assessing the toxicity of Special Antarctic Blend diesel fuel on soil biogeochemical processes on Macquarie Island. The dataset likely contains measurements of nitrification, denitrification, carbohydrate utilization, and total soil respiration across fuel concentrations from 0 to 50,000 mg/kg over a 21-day period. This work was completed as part of ASAC project 1163 and published via the Australian Antarctic Data Centre in 2005.
93 soil samples were collected along three parallel 300-meter transects on the Mitchell Peninsula in East Antarctica. The dataset likely contains measurements of organic carbon, nitrogen, exchangeable nutrients, texture, and pH, alongside DNA analysis for genotype diversity. It was collected by SCIOPS and last updated in November 2005.
Soil samples collected along three parallel transects at Browning Peninsula in East Antarctica. The dataset likely contains measurements of organic carbon, nitrogen, exchangeable nutrients, texture, pH, and microbial DNA genotypes. Data was collected by SCIOPS and last updated in November 2005.
93 soil samples were collected along three parallel transects at Casey Station in East Antarctica. Soil properties such as organic carbon, nitrogen, nutrients, texture, and pH were measured, and DNA was extracted for genotype analysis. The dataset was last updated by SCIOPS in November 2005.
Location records for soil water samples collected at Casey and Davis stations in Antarctica during January 2005. The dataset documents sample collection points but does not contain analytical results from the samples. It was created by the Australian Antarctic Data Centre.
Emissions of CO2 from manufacturing industries and construction detail fuel combustion and industrial process emissions, as defined by IPCC Source/Sink Categories. The dataset, provided by the International Energy Agency (IEA) via the CEOS_EXTRA organization, was last updated in December 2004. It includes emissions from coal, oil, and gas combustion, coke inputs in blast furnaces, and unallocated autoproducers.
Data from 2004-12-31 provides a biomass-based renewable energy supply index, as defined by the International Energy Agency (IEA). It covers biofuels like wood, vegetal waste, ethanol, and animal materials, with energy measured in KTOE units (41.868 Terajoules). The dataset is aggregated by the CEOS_EXTRA organization and hosted on the NASA Earthdata platform.
NOAA's Environmental Sensitivity Index (ESI) Atlas for Bristol Bay, Alaska, provides standardized maps and data for coastal shoreline sensitivity, biological resources, and human-use resources. The dataset is designed to identify sensitive environments before a spill to establish protection priorities and design cleanup strategies. It was created by NOAA and last updated in 2004.
