    Description: A dataset describing exposed bedrock and surficial geology of Antarctica constructed by the GeoMAP Action Group of SCAR (The Scientific Committee on Antarctic Research) and GNS Science, New Zealand. Legacy geological map data have been captured into a geographic information system (GIS), refining its spatial reliability, harmonising classification, then improving representation of glacial sequences and geomorphology. A total 99,080 polygons have been unified for depicting geology at 1:250,000 scale, but locally there are some areas with higher spatial precision. Geological definition in GeoMAP v.2022-08 is founded on a mixed chronostratigraphic- and lithostratigraphic-based classification. Description of rock and moraine polygons employs international GeoSciML data protocols to provide attribute-rich and queriable data; including bibliographic links to 589 source maps and scientific literature. Data are provided under CC-BY License as zipped ArcGIS geodatabase, QGIS geopackage or GoogleEarth kmz files. GeoMAP is the first detailed geological dataset covering all of Antarctica. GeoMAP depicts 'known geology' of rock exposures rather than 'interpreted' sub-ice features and is suitable for continent-wide perspectives and cross-discipline interrogation.

    Description: Sub-ice shelf circulation and freezing/melting rates in ocean general circulation models depend critically on an accurate and consistent representation of cavity geometry. Existing global or pan-Antarctic data sets have turned out to contain various inconsistencies and inaccuracies. The goal of this work is to compile independent regional fields into a global data set. We use the S-2004 global 1-minute bathymetry as the backbone and add an improved version of the BEDMAP topography for an area that roughly coincides with the Antarctic continental shelf. Locations of the merging line have been carefully adjusted in order to get the best out of each data set. High-resolution gridded data for upper and lower ice surface topography and cavity geometry of the Amery, Fimbul, Filchner-Ronne, Larsen C and George VI Ice Shelves, and for Pine Island Glacier have been carefully merged into the ambient ice and ocean topographies. Multibeam survey data for bathymetry in the former Larsen B cavity and the southeastern Bellingshausen Sea have been obtained from the data centers of Alfred Wegener Institute (AWI), British Antarctic Survey (BAS) and Lamont-Doherty Earth Observatory (LDEO), gridded, and again carefully merged into the existing bathymetry map. The global 1-minute dataset (RTopo-1 Version 1.0.5) has been split into two NetCDF files. The first contains digital maps for global bedrock topography, ice bottom topography, and surface elevation. The second contains the auxiliary maps for data sources and the surface type mask. A regional subset that covers all variables for the region south of 50 deg S is also available in NetCDF format. Datasets for the locations of grounding and coast lines are provided in ASCII format.

    Description: Labidocera spp. abundances measured from samples collected in Papua New Guinea at natural carbon dioxide seeps. Abundances are compared between two reefs (Dobu and Upa-Upasina) at control and high-CO2 sites for two expeditions. Data includes abundances from net horizontal tows and emergence traps. Data also includes information on life stages and animal lengths, as well as number of oocytes and gut fullness in adult females.

In: Bouma, AH; Coleman, JM; Meyer, AW; et al. (eds.), Initial Reports of the Deep Sea Drilling Project, Washington (U.S. Govt. Printing Office), 96, 767-775, https://doi.org/10.2973/dsdp.proc.96.147.1986
    Publication Date: 2023-05-12
    Description: Radiolabeled products were formed from labeled substrates during anaerobic incubation of sediments from Sites 618, 619, and 622. One set of experiments formed 14CO2, 14CH4, and 35SH2 from 2-14C-acetate and 35S-sulfate; a second set formed 14CH4 from 14C-methylamine or 14C-trimethylamine. Levels of 14CO2 and 35S2 formed were two to three orders of magnitude greater than 14CH4. Production of 14CH4 by Deep Sea Drilling Project (DSDP) sediments was four to five orders of magnitude less than that formed by anoxic San Francisco Bay sediment. However, incubation of Site 622 sediment slurries under H2 demonstrated production of small quantities of CH4. These results indicate that DSDP sediments recovered from 4 to 167 m sub-bottom (age 85,000-110,000 yr.) harbor potential microbial activity which includes sulfate reducers and methanogens. Analysis of pore waters from these DSDP sites indicates that bacterial substrates (acetate, methylated amines) were present.

    Publication Date: 2023-05-12
    Description: During DSDP Leg 94 sediment was recovered from 22 holes at six sites situated between 37° and 53°N in the North Atlantic. Paleomagnetic, calcareous nannofossil, foraminiferal, diatom, radiolarian, and dinocyst stratigraphic studies were completed. The excellent magnetostratigraphic results, the near-complete recovery, and the abundant fossil content of the sediment allowed refinement of these stratigraphies, especially for the upper Pliocene-Holocene. Because the Leg 94 sites span middle and high North Atlantic latitudes, it is possible to use them to evaluate the synchrony of late Pliocene to Holocene datums.
