  • 0.5 hour 1 M HCl extraction data for the Windmill Islands marine sediments

    https://cmr.earthdata.nasa.gov/search/concepts/C1214305813-AU_AADC.xml
    Description:

    These results are for the 0.5 hour extraction of HCl. See also the metadata records for the 4 hour extraction of HCl, and the time trial data for 1 M HCl extractions. A regional survey of potential contaminants in marine or estuarine sediments is often one of the first steps in a post-disturbance environmental impact assessment. Of the many different chemical extraction or digestion procedures that have been proposed to quantify metal contamination, partial acid extractions are probably the best overall compromise between selectivity, sensitivity, precision, cost and expediency. The extent to which measured metal concentrations relate to the anthropogenic fraction that is bioavailable is contentious, but is one of the desired outcomes of an assessment or prediction of biological impact. As part of a regional survey of metal contamination associated with Australia's past waste management activities in Antarctica, we wanted to identify an acid type and extraction protocol that would allow a reasonable definition of the anthropogenic bioavailable fraction for a large number of samples. From a kinetic study of the 1 M HCl extraction of two certified Certified Reference Materials (MESS-2 and PACS-2) and two Antarctic marine sediments, we concluded that a 4 hour extraction time allows the equilibrium dissolution of relatively labile metal contaminants, but does not favour the extraction of natural geogenic metals. In a regional survey of 88 marine samples from the Casey Station area of East Antarctica, the 4 h extraction procedure correlated best with biological data, and most clearly identified those sediments thought to be contaminated by runoff from abandoned waste disposal sites. Most importantly the 4 hour extraction provided better definition of the low to moderately contaminated locations by picking up small differences in anthropogenic metal concentrations. For the purposes of inter-regional comparison, we recommend a 4 hour 1 M HCl acid extraction as a standard method for assessing metal contamination in Antarctica.

  • 10 m firn temperature data: LGB traverses 1990-95

    https://cmr.earthdata.nasa.gov/search/concepts/C1214313574-AU_AADC.xml
    Description:

    The Lambert Glacier Basin (LGB) series of five oversnow traverses were conducted from 1989-95. Ten metre depth (10 m) firn temperatures, as a proxy indicator of annual mean surface temperature at a site, were recorded approximately every 30 km along the 2014 km main traverse route from LGB00 (68.6543 S, 61.1201 E) near Mawson Station, to LGB72 (69.9209 S, 76.4933 E) near Davis Station. 10 m depth firn temperatures were recorded manually in field notebooks and the data transferred to spreadsheet files (MS Excel). Summary data (30 km spatial resolution) can be obtained from CRC Research Note No.09 'Surface Mass Balance and Snow Surface Properties from the Lambert Glacier Basin Traverses 1990-94'. This work was completed as part of ASAC projects 3 and 2216. Some of this data have been stored in a very old format. The majority of files have been updated to current formats, but some files (kaleidograph files in particular) were not able to be modified due to a lack of appropriate software. However, these files are simply figures, and can be regenerated from the raw data (also provided).

  • 10 year trend of levels of organochlorine pollutants in Antarctic seabirds

    https://cmr.earthdata.nasa.gov/search/concepts/C1214305884-AU_AADC.xml
    Description:

    Metadata record for data from ASAC Project 2357 See the link below for public details on this project. ---- Public Summary from Project ---- Contaminants like PCBs and DDE have hardly been used Antarctica. Hence, this is an excellent place to monitor global background levels of these organochlorines. In this project concentrations in penguins and petrels will be compared to 10 years ago, which will show time trends of global background contamination levels. Data set description From several birds from Hop Island, Rauer Islands near Davis, samples were collected from preenoil (oil that birds excrete to preen their feathers. This preenoil was then analysed for organochlorine pollutants like polychlorinated biphenyls, (PCBs), hexachlorobenzene (HCB), DDE and dieldrin. The species under investigation were the Adelie penguin (Pygoscelis adeliae) and the Southern Fulmar (Fulmarus glacialoides). The samples were collected from adult breeding birds, and stored in -20 degrees C as soon as possible. The analysis was done with relatively standard but very optimised methods, using a gas-chromatograph and mass-selective detection. Data sheets: The data are available in excel-sheets, located at Alterra, The Netherlands (the affiliation of the PI Nico van den Brink.). Data are available on PCB153 (polychlorinated biphenyl congener numbered 153), hexachlorobenzene (HCB), DDE (a metabolite of the pesticide DDT), and dieldrin (an insecticide). The metadata are in 4 sheets (in meta data 2357.xls): 1. 'Concentrations fulmars' 2. 'Morphometric data fulmars' 3. 'Concentrations Adelies' 4. 'Morphometric data Adelies' The column headings are: 1. 'Concentrations fulmars' - Fulmar: bird number, corresponds with sheet 'morphometric data fulmars'. - PCB153: concentration of PCB-congener 153 (ng/g lipids) - HCB: concentration of hexachlorobenzene (ng/g lipids) - DDE: concentration of DDE (ng/g lipids) - Dieldrin: concentration of dieldrin (ng/g lipids) - Sample size weight of collected amount of preenoil 2.

  • 106-Mile Dumpsite Oceanographic Project (Mid Atlantic Bight); Surface Drifters and Hydrographic Measurements; NOAA/NOS

    https://cmr.earthdata.nasa.gov/search/concepts/C1214422215-SCIOPS.xml
    Description:

    The 106-Mile Dumpsite Oceanographic project is response to the Ocean Dumping Act (http://www.epa.gov/history/topics/mprsa/02.htm) which directs the National Oceanic and Atmospheric Administration (NOAA), the US Environmental Protection Agency (EPA), and the US Coast Guard to perform research, monitoring, and surveillance until ocean dumping of municipal sewage sludge is ended in 1992. NOAA is responsible for research and monitoring of the far-field and long-term effects of dumping at the dumpsite, which is located in the Mid-Atlantic Bight (MAB). Four 1991 seasonal deployments of four satellite-tracked drifters each and a single 1990 deployment of eight drifters were conducted across the continental shelf break and Dumpsite. The tracking and processing of near-surface drifters continues. Coupled with EPA weekly drifter deployments, the CEOB drifter study provides information on the relationship between suspended sludge dispersal to the near-surface circulation and interaction of shelf water, slope water, and Gulf Stream over the continental margin in the MAB. Hydrographic studies include quasi-synoptic conductivity and temperature profile and expendable bathythermograph (XBT) surveys of the MAB and dumpsite. These surveys were conducted in support of biological and chemical sampling and in conjunction with the deployment of drifters. Weekly transects were taken across the shelf, slope, and northern tip of the Dumpsite to the Gulf Stream from the ship of opportunity, M/V OLEANDER; this was an expansion of the monthly program managed by National Marine Fisheries Service's Northeast Fisheries Center, in Narragansett, Rhode Island.
