  • Trace metal concentrations are reported in micrograms per gram of sediment in core C012-PC05 (64⁰ 40.517’ S, 119⁰ 18.072’ E, water depth 3104 m). Each sediment sample (100-200mg) was ground using a pestle and mortar and digested following an initial oxidation step (1:1 mixture of H2O2 and HNO3 acid) and open vessel acid on a 150 degree C hotplate using 2:5:1 mixture of concentrated distilled HCl, HNO3 and Baseline Seastar HF acid. After converting the digested sample to nitric acid, an additional oxidation step was performed with 1:1 mixture of concentrated distilled HNO3 and Baseline Seastar HClO4 acid. A 10% aliquot of the final digestion was sub-sampled for trace metal analyses. Trace metal concentrations were determined by external calibration using an ELEMENT 2 sector field ICP-MS from Thermo Fisher Scientific (Bremen, Germany) at Central Science Laboratory (University of Tasmania). The following elements were analysed in either low (LR) or medium resolution (MR): Sr88(LR), Y89(LR), Mo95(LR), Ag107(LR), Cd111(LR), Cs133(LR), Ba137(LR), Nd146(LR), Tm169(LR), Yb171(LR), Tl205(LR), Pb208(LR), Th232(LR), U238(LR), Na23(MR), Mg24(MR), Al27(MR), P31(MR), S32(MR), Ca42(MR), Sc45(MR), Ti47(MR), V51(MR), Cr52(MR), Mn55(MR), Fe56(MR), Co59(MR), Ni60(MR), Cu63(MR), Zn66(MR).

  • This is a digital version of the grid reference map used to plot all sightings of Weddell seals in the Vestfold Hills. The point of origin is the same as the original map and each grid cell is numbered with the same numbering scheme. This can be used to plot any data using the same numbering scheme by joining (ArcInfo) or linking (ArcView) records to this coverage's polygon attribute table (pat) through the item GRIDREF. The original map was a 1:100 000 map of the Vestfolds, provided by Harry Burton, with a grid drawn over it. The grid references were given as either six or four figure values on which field scientists are to plot their data. This map has the following Antarctic Division drawing reference number: M/75/05A Some research with John Cox revealed that this grid was drawn up over a map digitised from another map with the following specifications: Scale 1: 100 000 Date: 1958 (reprinted 1972) Projection: Polyconic Published by: Division of National Mapping, Canberra Reference number: NMP/58/084 Data are referenced to a 'grid' of 1 minute spacing in x axis and 30 second spacing in y axis. The point of origin is apparently 68 20 S 77 48 E. There are 45 rows and 47 columns. The 'grid reference' is in fact in geographic coordinates (but using arbitrary units) so the projection of the original map became irrelevant. The procedure adopted to create a new digital grid was as follows: (Carried out in Arc/Info) 1. Generate a coverage using the original 'grid references'. 2. Tics were also generated using the corners of the 'grid reference' system. 3. A new coverage was created with tics at the same locations but given the true latitude/longitude vales. 4. The original coverage was then transformed to the new coverage based on the new tic values. 5. The new coverage was then projected from geographic coordinates to UTM metres. The data locations were then viewed in Arc/Info using a coverage of the coastline supplied by the Mapping Officer, Antarctic Division. This had previously been determined to be in the UTM projection. An offset was clearly visible between the data locations and the coastline. In order to determine whether the offset was more or less uniform, ten locations were plotted from the original data onto the original map using the 'grid'. Finally a manual corrected was made by moving all the data locations by a uniform distance of 508 metres north and 68 metres west. Information from John van den Hoff, February 2019: The grid cells were originally labelled from 1 to 47 along the x axis and 1 to 45 along the y axis. The four digit values in the GRIDREF field of the attribute table are the x value followed by the y value. To avoid confusion between x and y values, the grid was later revised so that the y values were prefixed with a ‘1’ so for example 01 became 101. The GRIDREF_X and GRIDREF_Y fields have the x and y values of the revised grid. This needs to be kept in mind when data is sourced from field books. The map shows the revised grid.

  • Scanned copy of an acoustics log from Casey Station. Data were collected during 1997. There is no accompanying information to go with the log.

  • This dataset contains the results from surveys of Wandering Albatrosses (Diomedea exulans) on Macquarie Island. The majority of the surveys were conducted at the Caroline Cove colony which contains 59% of the Wandering Albatrosses found on Macquarie Island. Observations were made for 41 consecutive days between 5 December 1975 and 14 January 1976, and for 103 consecutive days between 25 November 1976 and 7 March 1977. Occasional observations were made of birds at other locations on Macquarie Island. Each bird in the colony was banded for identification, sexed and had its plumage scored. The times of arrival and departure, numbers present, interaction and behaviour were observed, and weather conditions were noted irregularly throughout the day. The results are listed in the documentation.

  • Access database containing biological and environmental data collected by the Australian Antarctic Division, Human Impacts Benthic Biodiversity group.

  • A summation of survey tasks conducted within the Davis Station surrounds is as follows: • Priority 1 – Wharf Area: Feature survey of a designated area surrounding the Davis wharf at a 10m grid spacing. However, due to the small area of the wharf, a 10m external buffer was applied to ensure there are no data gaps on completion of the survey and a 5m natural surface grid was collected including all services that were joined or contained within the region. • Priority 2 – Feature survey of a designated area to the North East of the Bureau of Meteorology and General Science buildings. A region approximately 150m x 380m. A detailed pickup of the existing electrical, optic fiber, telecommunication lines, high frequency radio mast and guide wires were collected including the location of the BoM instruments. Natural surface collection was collected at a 10m grid spacing.

  • The Australian Collection of Antarctic Microorganisms (ACAM) was established in 1986 at the University of Tasmania as a collection for microorganisms from the Antarctic continent as well as from subantarctic islands and the Southern Ocean. ACAM is one of the few collections in the world dedicated to the collection of Antarctic bacteria and since its inception has grown to nearly 400 strains. Many of these strains have been isolated from lakes and marine waters in the Vestfold Hills region of Antarctica near Davis Station. Salinity, redox potential, light and temperature all vary dramatically between these water bodies and, on many occasions, have been shown to vary with water depth within them. Microorganisms living in these ecosystems cope with a variety of physical extremes which characterise the Antarctic environment. The potential for biotechnological use of Antarctic microorganisms has become more evident from basic studies on the taxonomy and molecular biology of antarctic microbes. Recently, bacteria have been isolated that (i) contain polyunsaturated w-3 fatty acids, (ii) degrade hydrocarbons (including polycyclic aromatics) and (iii) produce bioactive natural products. ACAM is a continually expanding collection. The search for Antarctic microorganisms that may be commercially exploited has only just begun. Future research should identify novel strains that offer further potential for biotechnology and, at the same time, provide a better understanding of the Antarctic ecosystem. ACAM is now available through the Australian Antarctic Data Centre's Biodiversity database, or via the ACAM website. This work was completed as part of ASAC project 65 (ASAC_65).

  • We checked each site by taking ice cores and observing the algae biomass to determine the likelihood of krill living under the sea ice in each location. We also used a Remotely Operated Vehicle (ROV) with cameras attached to observe the abundance of krill under the sea ice. If krill were present we used on the sea ice floe a zooplankton pump, called MASMA, according to Meyer et al. 2009, whereas at the edge of the floe column a custom-built fish pump system was used to collect krill near the surface. The Aqualife Biostream BP40 fish pump was capable of pumping up to 1300 litres per minute without harming animals that pass through the pump. For much of the voyage it was operated from the ctd room and at this increased suction head it ran at about 500 litres per minute. Krill were caught at ice stations 2, 6, 7 and 8. The Krill Sample-Overview.xls file contains information regarding how many krill were caught at each ice stations, who was involved and related information. The SIPEX II Krill Voyage Report.docx contains information about the various issues that were encountered during the voyage. It also contains information from the Bottom Krill experiment, which has its own dataset and metadata record. It is duplicated in both datasets. The larvae were used for a growth experiment using the IGR method and after length measurements frozen for carbon, nitrogen, lipids, stomach and gut content analysis. The total and carapace length were determined of juveniles as well as their digestive gland size. Animals were than dissected and tissues frozen at -80C for further analysis (see above). These condition parameters will be discussed in relation to physical and biological environmental parameters of the ice floe (e.g. sea ice thickness, snow coverage, under ice topography and biomass). When this data is analysed, the dataset will be updated to include analysed versions of the data listed in the Krill Sample-Overview.xls file. Also included in the dataset are technical documents and manuals pertaining to the fish pump that was used. Meyer B et al. 2009. Limnol Oceanogr 54:1595-1614
