It’s early Sunday morning at Halley Research Station, Antarctica. The sun is rising quickly on the horizon, the wind is low and the temperature outside is a modest -18 degrees C. Conditions look perfect. As I look across the dining room at my friends and colleagues Niv and Colin I see two smiling faces nodding back at me. Today we are going to head out to the coast and attempt to explore a large crevasse at a point on the Ice shelf known as Creek Five.
Halley Research Station sits on the Brunt Ice Shelf 15km in from the edge of the shelf. It is the British Antarctic Surveys most southerly and remote research station. I am lucky enough to be a member of the eleven strong wintering team working as the chef on Station. With the impending arrival of 24 hour darkness we are all keen to make the most of the remaining daylight, taking every opportunity to make the most of our time in this amazing place.
During the winter months on the Antarctic continent not only do we experience 24 hour darkness but we are privileged to see the aurora australis. Here at Halley Station we were looking forward to experiencing many a night gazing at the dancing lights as they flitter across the sky. Reading the small print however, revealed that there is a cycle of activity that revolves around an 11 year period. It seems that 2009 is a low solar activity year and hence our expectations might have been a bit high.
Large flares or solar explosions from the sun will expel numerous amounts of solar particles which make their way towards Earth. These particles come into contact with the Earth’s magnetosphere and are directed towards the polar regions. High energy particles then cascade into the highest parts of the Earth’s atmosphere, ionising gases. It’s this process that emits the glows that we see on Earth. The variation of colour is a result of particles with different energies ionising different gases.
VP-FBB on the Antarctic Plateau
As I take off from the ice runway at the British Antarctic Survey’s Halley base, situated on the Brunt Ice Shelf (75o34’S 26o34’W), I finally realise I am living and working at the extreme of human endurance. I am in one of the Survey’s De Havilland Twin Otters, known as Victor Papa Foxtrot Bravo Bravo (or VP-FBB), heading to the remote automatic weather station known affectionately as Baldrick, located at 83oSouth.
The weather station is hundreds of miles from the nearest living thing (human or otherwise) in the middle of the most inhospitable environment on the planet. My life is entirely in the hands of the pilot Mark; fortunately they are very skilled hands.

Introducing Halley Station (75°34’S 26°34’W), located on the 150m thick, continually moving, Brunt Ice Shelf in Antarctica. Named after the Astronomer Edmond Halley, the current station (Halley V) is the fifth to be built. It is the British Antarctic Survey’s most remote research station and has been operational since 1956 (established by the Royal Society for the International Geophysical Year, 1957-58). Halley Station (also known as Base Z) has presented itself in many forms since those first buildings in 1956.
The extreme environment challenges even the most thought out buildings. Blizzards and snow drifts eventually bury any structures left on the ground and the constant movement of the ice shelf compresses any structures under the surface, making these buildings eventually unsuitable for use.
