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.

AM01b borehole drilled mid-December 2003. Profiling measurements conducted over a period of a few days. Video recording of borehole walls and sea floor benthos. Sediment sample collected from sea floor. No long term monitoring instruments installed. AM01b borehole was drilled within a few hundred metres of where the ice shelf had carried the original AM01 borehole to, in the intervening 2 years. As the AM01 borehole had a mooring suite of instruments, none were emplaced in the AM01b borehole.

The aim of the study was to characterise the genetic biodiversity of populations of the copepod Paralabidocera antarctica and the cladoceran Daphniopsis studeri in the Australian Antarctic Territory. Sampling was finalised during November and December 2000. Daphniopsis studeri were sampled from freshwater lakes in the Vestfold and Larsemann Hills, and from small ponds on Heard Island. Paralabidocera antarctica were collected from saline lakes, fjords and embayments around the Vestfold Hills. Each population was analysed at 16 allozyme loci using cellulose acetate electrophoresis. Allozyme data were recorded as multilocus genotypes for each individual. The observed number of multi-locus genotypes were tested against expected values to determine whether populations of Daphniopsis studeri reproduce by obligate or cyclic parthenogenesis. Geographic genetic structure of the crustacean populations was assessed using genetic distance measures and cluster analysis. Local and regional gene flow was estimated using Fst and multivariate statistics. By using genetic tools to measure indirectly dispersal and gene flow among populations with each species, we hope to reconstruct the history of these species in Antarctica and to determine the relative significance of historical versus contemporary ecological conditions.
