Creatures to be featured in 'Ice Station Antarctica'
Written by Alex Gaffikin
As we continue to organise our life on board for the long polar night ahead, a constant preoccupation is the production, use and discharge of water. Ensuring that we have a sufficient amount of good quality water for our basic needs is a big task for at least two people each day. Like most large boats, we have a watermaker onboard that makes freshwater from seawater through the process of osmosis.
In temperate climates we can produce up to 200 liters per hour. However, in our current position close to 83 degrees north the water temperature is -1.5 degrees celsius and the temperature in the forward hold (the location of the watermaker) has descended to -7 degrees, below the minimum operating temperature of 0 degrees. Therefore, we now produce our water by melting ice and sno...

This image is the design for the Interpolar Transnational Art Science Constellation (I-TASC) mobile research station, which we are planning to deploy in Dronning Maud Land, Antarctica and Igloolik, Nunavut during IPY.
The I-TASC station is an autonomous, zero-environmental impact, communications, research and living unit capable of sustaining up to 8 crew members for long periods of work in isolation/insulation conditions (60-180 days). Onboard renewable-energy systems, bioreactor/biological sewage processing, water recycling systems, satellite and HF communication systems and radar infrastructure will provide the I-TASC crews of artists, scientists, engineers and tactical med...

Frank Bickerton and the Australasian Antarctic Expedition (1911-14)
Written by Glenn Stein
A biographer's challenge is to rekindle the spirit of a person, and this has recently been accomplished by Stephen Haddelsey in his book Born Adventurer: The Life of Frank Bickerton, Antarctic Pioneer.
Bickerton, born in England in 1889, is today largely unknown, though his adventures were daring and remarkable — Haddelsey recounts his travels into the equatorial rainforest of the Cocos Islands and his airplane dogfights over the Western Front during World War I. But it is Bickerton's Antarctic experiences that dominate the book, and...
The European Polar Board and Swedish Research Council recently week hosted a workshop in Tarfala, northern Sweden, focussed on developing outreach and communication efforts in Europe. It was an amazing venue, set at a research station surrounded by glaciers. The group consisted of artists, writers, press and media, photographers, publicity professionals, museum curators, scientists and IPY national representatives.
On a hike up to a glacier, I asked one new colleague, Luigi Folco from the Museo Nazionale...

Vagabond is at Ny Ålesund since 1st September. France and I are preparing the third winter and are using the facilities of the AWIPEV Research Base. Varnishing, painting, servicing and various maintenance, cleaning, packing, sorting out, supplying of food... activities are many and varied on board! Between 2 jobs, we are exploring the surroundings with mountain bikes pulled by our dogs, paddling at sunset between drifting ice in the great King's Bay, watching the reindeers or polar foxes coming right into the village, talking - and sharing a drink - with scientists or technicians... a talk about our 2 first winters in Spitsbergen is planned here on 12 September, and we will also jump into the jacuzzi!

Polar History: 1845 – The Franklin Expedition
Written by Glenn Stein
On May 19, 1845, Sir John Franklin, commanding HMS Erebus and Terror, left England to search for an elusive North-West Passage (see image). This was only the latest in a long series of expeditions stretching back 350 years, seeking a maritime route connecting the Atlantic and Pacific Oceans through the Arctic. But this expedition was different from all the rest — both ships and 129 men vanished in the Arctic wastes. By 1847, there was growing concern for the missing expedition, and both overland and seaborne search parties were dispatched to try and find Franklin and his men.
For over a decade, British and foreign expeditions combed the Arctic, first to rescue the explorers, and later to ascertain their fate. A document recovered in 1859 revealed that...

Aug 16: Our last few days at sea since Cape Chelyuskin have passed much like the rest since Murmansk, albeit with heightened excitement for our arrival in Tiksi. Little wind and calm conditions allowed us to make a test of our new sounder. Capable of measuring to a depth of 4,000m, this instrument will be important during the drift to assess the depth before making a CTD sounding.
However, for now our minds are turned to the coming few days in our last port of call before two years in the high Arctic Ocean. Early this afternoon, shortly after fastening the mooring lines, we had the pleasure of receiving an official welcome from the people of the Sakha Republic. Adorned in traditional robes, singing and offering food and drinks provided an unexpected but appreciated reception...
