Davis station, which is
Australia’s most southerly base is located in one of the largest
ice free areas of the Antarctic continent known as the Vestfold
Hills.
The Vestfold's have a few interesting claims-to-fame;
The first landing in the Vestfold Hills were by Norway’s Captain Klarius Mikkelsen and his
wife Caroline on the 20th February 1935 which makes it the site of
the first female to set foot in Antarctica!
The hills which cover
an area of 411 square kilometres are dotted with around 300 lakes and
ponds. Many of these lakes are like none other in the world. Some
have water that is 10x as salty as sea water and never freeze, even
in the -30 odd temperatures of winter.
Some are stratified
which means they have distinct layers of temperature, salinity,
oxygen and other factors which never mix.
Recently some have been
found to host new species of Virophage which are viruses that prey on
other viruses and there are also single cell organisms found in some
lakes that can change between plants and animals depending on the
amount of light and sources of food and energy around!
The hills also have an
interesting feature called 'Dykes' which are dark strips of rock that
seem to run in perfectly straight but random directions.

Close by station during the summer there are a multitude of animals to be found. Many of the islands close by are home to Adelie penguin colonies where they come to breed. There are also numerous 'wallows' where male Elephant seals come to moult. Many of the Vestfold's Fjords and inlets make perfect locations for Weddell seals to pup and the rocky ground suits birds such as Snow and Wilson Storm Petrels and Skuas.
The station itself is
located on the coast of Broad Peninsula. During summer it homes
around 70-90 expeditioners. During winter the number drops to around
15-20. We have numerous buildings and facilities here which I plan on
going into more depth about as the months progress.
Anyway, Ill leave you all with
a couple of pics of some weather we have been having over the last
few days. Its surprising how quick the weather can change from -15
and little wind to -1 and a 120kph blizzard!
