Four ice monitoring stations were set up at Davis in 1993 (a fifth station was added after the first two months), with regular recordings of ice depth, snow cover and ablation made for each station by taking a sea ice core. Observations of the general condition of the drilled cores were also recorded. Observations were made at irregular intervals (roughly every 1-2 weeks). The observations for each individual day are listed, along with a summary table. These records are stored as handwritten files, and are archived at the Australian Antarctic Division.

This metadata record will contain the results of analyses of tissue samples from Antarctic Rock-cod (Trematomus bernacchii) collected at sites around Davis station to determine wastewater exposure and sub-lethal impact. AAS Project 4177. The results of metal analysis, stable isotope analysis and images of histological analysis of fish from Davis Station are in this dataset. Sample sites and fish collection Antarctic Rock-cod were collected at 6 sites from Prydz Bay near Davis Station East Antarctica, during the 2012/13 summer. Approximately twenty fish were collected from each site by line and in box traps from four sites along a (9 km) spatial gradient starting from the Davis Station wastewater outfall, southward 0km (within 250m of the point of discharge), 1km, 4km and 9km, in the direction of the predominant current. Additionally, two reference sites were sampled 9 km and 16 km north of the discharge point. Once collected, fish were immediately returned to the Davis Station laboratories and sacrificed individually by immersion in an Aqui-s solution (~15ml/L). Once no signs of life were present (approximately 5 min), fish length and weight were measured. Tissues were preserved in various ways for a number of analyses to be conducted at a later date. Stable Isotope analysis. Davis Station Laboratory Dorsolateral muscle tissue from the left side of each individual was removed, placed in aluminium foil and frozen at -20 degrees C for later analysis. Tissue processing A section of frozen tissue was removed (approximately 1 x 1 cm cubed), placed into a clean, acid washed glass crucible and cut into small pieces. This was then dried at 80 degrees C for 48 h. Tissue from each fish was carefully removed and placed into separate 2 ml Eppendorf tubes, each containing an washed, dried stainless steel ball bearing and the lids closed tightly to ensure no moisture could enter. Tissue was crushed into a fine powder by shaking in a Tissue II Lyser. Ball bearings were removed from vials and crushed tissue samples were sent to Cornell University Stable Isotope laboratory for d13C (carbon stable isotope) and d15N (nitrogen stable isotope) analysis. Stable isotope ratios are expressed in parts per thousand units using the standard delta (d) notation d13C and d15N. Data Set This data set consists of an Excel spreadsheet containing raw data of Nitrogen and Carbon Stable Isotope analysis from 6 sites in the Prydz Bay area of East Antarctica.

Tissue was sectioned using a HM 32 Micron microtome at 4 microns. Standard haematoxylin and eosin (H and E) stain was used to stain all tissue sections. Each section was examined blind (i.e. the examiner did not know the field location of the tissue samples) using a Zeiss AxioPlan microscope at 100-400 x magnification. Histological analysis is ongoing. Data Set This data set consists of a pdf file with images of normal and potential sub-lethal histological alterations.

From February to March 2010, Geoscience Australia (GA) conducted a multibeam sonar survey of the coastal waters of the Vestfold Hills in the Australian Antarctic Territory. The survey was conducted jointly with Australian Antarctic Division (AAD) and the Deployable Geospatial Survey Team (DGST) of the Royal Australian Navy. The survey was aimed primarily at understanding the character of the sea floor around Davis Station to better inform studies of the benthic biota and the possible impacts of the Davis sewage outfall. DGST were involved to ensure that the bathymetric data could be used to update and extend the nautical charts of the Davis area. The survey was conducted using GA's Kongsberg EM3002D multibeam echo sounder and C-Nav Differential GPS system mounted on the AAD work boat Howard Burton. Sixteen under water videos were also collected using the GA Raytech camera system and 3 grabs were also collected to compliment an intensive sampling program by AAD divers and a sampling program conducted in the 1990's by University of Tasmania (Franklin, 1996). An area of 42 km2 was surveyed intensively immediately off Davis and additional survey lines were run to Long Fjord in the north and to Crooked Fjord and the Sorsdal Glacier in the south. The main survey area had between 150% and 200% coverage as the seabed was esonified from opposing angles to resolve and provide detail to the numerous features of the seafloor such as rocky reefs, iceberg scours, boulders, anchor chain drag marks and grounded icebergs. The new high resolution data provided detailed maps of sea bed morphology and texture classification to complement sample data. Sixteen video transects were collected and 3 grab samples collected in water too deep for the Australian Antarctic Division Diving program. New high resolution bathymetric grids have been prepared for scientific use and further processing for hydrographic charting is ongoing. A new sea floor geomorphic map has been prepared using the multibeam data, preliminary video and sampling data. The project was a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities. In 2011, Dr Phil O'Brien provided to the Australian Antarctic Data Centre the following interim data: 75 cm multibeam data in CARIS format; and a 4 metre resolution bathymetric grid and an image of the sea floor, both derived from the 75 cm multibeam data. This data was made available for download from this metadata record. In August 2013, Geoscience Australia released 2 metre resolution bathymetric and backscatter grids after further processing of the multibeam data. The bathymetry and backscatter data have now been fully processed checked and validated by Geoscience Australia and supersede the interim data. The interim data has been archived by the Australian Antarctic Data Centre. The 2 metre resolution grids and final report are available for download from the Geoscience Australia website.

Personnel: B.A.Murphy (1985), I.P.Kaczerepa (1984-85), R.A.Sheridan (1984-85, 1985-86), E.W.MacGibbon. The primary aim of the 1984-85 summer surveying program was to continue with the establishment of the vertical control network on Long, Broad and Mule Peninsulas which would enable periodic and accurate monitoring of water level fluctuations of specified fresh and saline lakes in the Vestfold Hills. Other work completed included Davis magnetic and gravity stations, Department of Housing and Construction site surveys, coordination of RAN Miniranger sites, deployment of tide gauges and horizontal control station surveys. During the 1985-86 summer survey program two major tasks were to be undertaken. The first was to complete loop closures of vertical control networks on Long, Broad and Mule Peninsulas and the second to coordinate Dr Gallagher's long/cross section origin points along the length of Ellis Fjord. Miscellaneous other survey tasks were also carried out including deployment of a tide gauge.
