Water depth measurements were taken in Long Fjord during early winter in 2007. The measurements were collected by Graham Cook, station leader at Davis Station in the Australian Antarctic Territory. The measurements were made by dropping a weighted line off the back of a quad bike, after drilling a hole through the sea ice. Measurements were made approximately every 100 metres. The download file contains a csv spreadsheet which lists each waypoint, plus the corresponding water depth and any comments. The text file contains the waypoint information collected by the Garmin GPS unit. Data in the text file are comma separated and are interpreted as follows: WP,D,001 (waypoint) , -68.51341000, 78.06903000,(Latitude and Longitude) 05/25/2007, 10:25:35, (Date and time Downloaded to Computer) 24-MAY-07 11:40:42 (Date and time of reading). Time is in local time. Vegetation was found on the weight that we used when we first started at the seaward end of the Fjord and then again in shallow water between Brookes Hut and a small island 800 or 900 metres out from Brookes. The weight is quite smooth and does not pick up a lot. The reference given below provides some further information about previously collected bathymetry data in Long Fjord. Furthermore, also see the metadata records: 'Bathymetric data of Long and Tryne Fjords at Vestfold Hills, Antarctica, collected in December 1999 [VH_bathy_99]' 'Interpolated bathymetry of Long and Tryne Fjords, Vestfold Hills, Antarctica [long_tryne_bathy]' The fields in this dataset are: Waypoint Latitude Longitude Water Depth Date Time

This is a scanned copy of the report of sediment core activities at Davis Station, 1985 by Lin Jian-ping. Paraphrased from the abstract of the report: Sediment deposited in the bottom of water provide a historical record of the biological and chemical changes which have occurred in the places since they were formed. One of the research programs at Davis in 1985 was the sediment coring program. Sediment cores were taken from some places of the Vestfold Hills, Antarctica, and were analysed for water content, total organic content and non-polar lipid content.

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).

A bibliography of papers on microrganisms from polar areas. Publication dates of papers in the collection range from 1847 to 2002. The bibliography was compiled by Dr David Wynn Williams of the British Antarctic Survey (BAS). Dr Williams is now deceased.
