Annual report on the scientific work undertaken at Davis Station in 1985

This is a scanned copy of the annual report on the scientific work undertaken at Davis Station in 1985.  The report was written by J.B. Gallagher.
Paraphrased from the introduction:
This report describes the work undertaken at Davis from January 1985 to November 1985.
Aims of the program:
1) Description of the seasonal circulation patterns within Ellis Fjord.  This was done by measuring the salinity temperature profiles at selected stations down the length of the fjord, its entrance and the sea.
2) Origin, age, circulation and mixing rates of the meromictic basin.  The deep waters of the meromictic basin have a salinity of approximately 1.4 the salinity of sea water.  It's possible that this may be due to old sea water left behind after an isostatic uplift with subsequent concentration through evaporation.
Calculation of mixing rates and description of the water circulation will explain why the basin is so stable.
3) Recent sedimentation rates within the meromictic basin.  Sediment was collected from 110m for 137Cs analysis - the peak in the profile should indicate the age of that layer of sediment as 1963, during which atmospheric bomb tests released large quantities of 137Cs into the atmosphere.
4) Biogeochemistry of sulphur, iron, manganese, aluminium and carbon within the meromictic basin.  The deep waters of the meromictic basin are anoxic (from 45m).  This gave an ideal opportunity to study the cycling of the above redox active elements.
5) Collection and processing of water for trace element analysis and organometallics.

Locations of samples from Organic Lake, Deep Lake and Ellis Fjord in the Vestfold Hills, Antarctica

This data set contains locations of sample sites for Ellis Fjord (1989), Organic Lake (1985) and Deep Lake (1975, 1975) in the Vestfold Hills. 
Unfortunately little is known as to what samples were collected.  It is believed that water samples were taken at all locations, and that bottom sediment samples were taken at least at Deep Lake.
When questioned in 2009, the investigating scientist was unable to remember exactly what work was done.  The original maps may provide some clues.

Adelie penguin occupancy survey of the Windmill Island group, 2011

An occupancy survey in January 2011 found a total of 14 islands/sites in Windmill group had populations of breeding Adelie penguins. The boundaries of breeding colonies at 11 of the 14 islands were subsequently mapped for abundance surveys.  Four of the islands, Nelly Island, Hollin Island, Midgley Island and Beall Island were mapped from aerial photos taken in January 2011. Images were taken on the 2 January 2011 [Hollin, Midgley, Beall] and 23 January 2011[Nelly]. Mapping involved digitising polygons around sub-colonies from vertical aerial photographs. The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.

Diet results from Adelie penguins at Bechervaise Island and Whitney Point, 2012-2013

These spreadsheets provide the proportions of prey DNA sequences in the scats of Adelie penguins at Bechervaise Island and Whitney Point in East Antarctica.  
Samples were collected during two stages of the breeding season: mid brood guard (Bechervaise Island-January 4-6th 2013, Whitney Point 23- 28th December 2012) and mid creche (23-26th January 2013).  Scat samples were collected from breeding birds, chicks and non-breeders at Bechervaise Island and breeding birds and chicks at Whitney Point. 'Breeders' were identified as individuals brooding or provisioning a chick, whereas 'non-breeders' were usually pairs that had reoccupied the colony and were building new practice nests with no chick present.  Non-breeders in the colony include immature birds that have not yet bred and mature birds of breeding age that did not breed in a particular season (e.g. no partner or insufficient body condition)
DNA from each sample was extracted and sequenced as per the protocols in the following paper:
Jarman, S.N., McInnes, J.C., Faux, C., Polanowski, A.M., Marthick, J., Deagle, B.E., Southwell, C. and Emmerson, L. 2013 Adelie penguin population diet monitoring by analysis of food DNA in scats. PLoS One 8, e82227. (doi:10.1371/journal.pone.0082227).
The Raw Data spreadsheet contains the proportion of each prey group of each individual sample, plus the total sequence count of prey items.  Only samples with greater than 100 prey sequences are included in the dataset.  The summary datasheet contains only prey taxa which contained greater than 2% of the proportion of sequences.
Analysis of these data have been published in: McInnes JC, Emmerson L, Southwell C, Faux C, Jarman SN. (2016) Simultaneous DNA-based diet analysis of breeding, non-breeding and chick Adelie Penguins http://dx.doi.org/10.1098/rsos.150443

Islands NE of Brattstrand Bluff penguin GIS dataset

Aerial photography (35mm film) of penguin colonies was acquired over some islands north east of Brattstrand Bluff islands (Eric Woehler).
The penguin colonies were traced, then digitised (John Cox), and saved as DXF-files.
Using the ArcView extension 'Register and Transform' (Tom Velthuis), The DXF-files were brought into a GIS and transformed to the appropriate islands.
Update May 2015 - 
This dataset has been rename from "Brattstrand Bluff penguin GIS dataset" to "Islands NE of Brattstrand Bluff penguin GIS dataset" to better describe the location of the colonies. The penguin colonies are on a small group of islands approximately 12km north east of Brattstrand Bluff. Latitude 69.148 south and longitude 77.268 east.
The Data Centre does not have a copy of the original photographs or described GIS data. In May 2015, the Data Centre has attached the following to this record:
The DXF file produced by John Cox by digitising the aerial photography. Note this document is not georeferenced.
Four photographs taken in 2009 by Barbara Wienecke, Seabird Ecologist, showing penguin colonies on these islands.
A shapefile exists of the digitised colonies. The digitising by Ursula Harris, Australian Antarctic Data Centre, was done by georeferencing the DXF drawing over unprocessed Quickbird Image 05NOV15042413-M1BS-052187281010_01_P002. It was done in two parts, the largest island and then the two smaller islands. This allowed for better matching. The accuracy of this data is unknown.

Perth Canyon Marine Park Bathymetry - 40m Resolution Grid

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new marine data.  “Eco-narrative” documents are being developed for those parks, where sufficient information is available, delivering collations and interpretations of seafloor geomorphology, oceanography and ecology. Many of these interpretations rely on bathymetric grids and their derived products, including those in this data release.
Bathymetry grids
The bathymetry of the marine parks was created by compiling and processing Geoscience Australia’s bathymetry data holding gridded at the optimum resolution depending of the vessel’s sonar system.
The bathymetry of the park is illustrated by a panchromatic geotiff image, developed by combining the bathymetric data with a hillshade image.
Morphological Surfaces
Geoscience Australia has developed a new marine seafloor classification scheme, which uses the two-part seafloor mapping morphology approach of Dove et al (2016). This new scheme is semi-hierarchical and the first step divides the slope of the seafloor into three Morphological Surface categories (Plain, &lt;2°; Slope, 2-10°; Escarpment, &gt;10°).

Behaviour of Weddell seals during winter recorded by satellite tracking.

This data set contains the results from a study of the behaviour of Weddell seals (Leptonychotes weddelli) at the Vestfold Hills, Prydz Bay, Antarctica. Three satellite transmitters were deployed on tagged female Weddell seals at the Vestfold Hills mid-winter (June) 1999. The transmitters were recovered in December, late in the pupping season. In total, the three transmitters were deployed and active 170 days, 175 days and 180 days. I used the first two classes of data to get fixes with a standard deviation less than 1 km. Most seal holes were more that 1 km apart (see Entry: wed_survey) so at this resolution we can distinguish between haul-out sites. We examine the number and range of locations used by the individual seals. We use all data collectively to look at diurnal and seasonal changes in haul-out bouts. None of the seals were located at sites outside the area of fast ice at the Vestfold Hills, although one seal was sighted on new fast-ice (20 - 40 cm thick). Considering the long bouts in the water, and that we only tracked haul-out locations, the results do not eliminate the possibility that the seals made long trips at sea.
The original data are stored by the Australian Antarctic Division in the ARGOS system on the mainframe Alpha. The transmitter numbers are 23453, 7074 and 7075.

Iron(II) measurements on water column samples collected on the SIPEX II voyage of the Aurora Australis, 2012

Water samples for dissolved trace metal measurements were collected from the surface (15m) down to the 1000m using an autonomous intelligent rosette system (General Ocanics, USA) specially adapted for trace metal work and deployed on a Dyneema rope. The rosette was equipped with 12x10-L Niskin-1010X bottles specially modified for trace metal water sampling. This system has been successfully deployed on the RSV Aurora Australis during voyages au0703 and au0806. Care was taken to avoid any contamination from the ship and the operating personnel. Water samplers were processed aboard under an ISO class 5 trace-metal-clean laminar flow bench in to a trace-metal-clean laboratory container on the ship's trawl deck. All transfer tubes, filtering devices and sample containers were rinsed liberally with sample before final collection. Samples were then drawn through C-Flex tubing (Cole Parmer) and filtered in-line through 0.2 micron pore-size acid-washed capsules (Pall Supor membrane, Acropak 200). 
Regular sampling depths were as follows: 1000m, 750m, 500m, 300m, 200m, 150m, 125m, 100m, 75m, 50m, 30m, 15m. 
Samples were analysed within a minute of filtration. Iron(II) was detected with the luminol method combining the experimental set-up of Hansard et al. (2009) with the chemistry as described by Croot and Laan (2002). Samples were not acidified prior to analysis and were pumped directly into the flow cell without an injection valve. Care was taken to maintain a stable light field during measurements as the luminol reagent was found to be extremely sensitive to changes in light intensity.
Photons from the reaction of luminol with iron(II) were counted with a Hamamatsu photomultiplier tube housed in a light-tight box. The signal was recorded using FloZ software (GlobalFIA) and the data for each run is stored in a separate file. There is a folder for each profile that contains all the files (automatically generated by the software), which are numbered. The file numbers (e.g. sample1, sample2,...) correspond to the runs as noted in the lab book (see scans).

antFOCE Ambient Seawater Temperature

Refer to antFOCE report section 2.3 for deployment, sampling and analysis details.
https://data.aad.gov.au/metadata/records/AAS_4127_antFOCE_Project4127
The download file contains an Excel workbook with a series of data spreadsheets - one for each of the Onset Hoboware Tidbit  v2 (UTBI-001) temperature loggers that were attached to the outside of various pieces of the underwater experimental infrastructure across the antFOCE site. A Notes spreadsheet is also included with information relevant to the data.  
Background 
The antFOCE experimental system was deployed in O'Brien Bay, approximately 5 kilometres south of Casey station, East Antarctica, in the austral summer of 2014/15. Surface and sub-surface (in water below the sea ice) infrastructure allowed controlled manipulation of seawater pH levels (reduced by 0.4 pH units below ambient) in 2 chambers placed on the sea floor over natural benthic communities. Two control chambers (no pH manipulation) and two open plots (no chambers, no pH manipulation) were also sampled to compare to the pH manipulated (acidified) treatment chambers.  
Details of the antFOCE experiment can be found in the report – "antFOCE 2014/15 – Experimental System, Deployment, Sampling and Analysis". This report and a diagram indicating how the various antFOCE data sets relate to each other are available at:
