Climbing electricity pylons in Taunton
The first part of the mast course took place at the SWEB training centre in Taunton, Somerset. The course was designed for people working with the electricity company and SWEB had a small pylon in the grounds to practice climbing on.

Our instructor was Mike. He taught us how to check and put on our harnesses. He then showed us how to climb using fall arrest equipment called "cow-tails" so that we were always attached to the mast.

My first challenge was to climb the mast and attach a pretend satellite dish. I had to learn to trust the "close working attachment" - a rope which loops around your body and hooks onto the mast - so that both my hands we free. My knees were like jelly and it took a lot of self persuasion and yelling / encouragement from Mike for me to take both hands off the pylon.

While we were in Taunton we stayed at a marvellous hotel where we ate a three course meal every night - including a delicious Pavlova pudding. As I got heavier and heavier during the week it got progressively harder and harder to clamber up the mast!

Mast erection in Cambridge
The following week, Mike came up to Cambridge to show us how to put up masts.

We spent a couple of days in the courtyard behind BAS putting together a mast and then dismantling it. It was mid-summer and blazing hot and in no way prepared me for how gruesome the same job would be in Antarctica.

... and in Antarctica
In Antarctica I had to climb a similar mast but with thick gloves and big boots on. Hanging around up a mast in Antarctica is exceedingly unpleasant - my fingers and toes went numb, the rungs are slippery with rime and I had to be careful not to touch the metal in case I stuck to it.


Mast climbing at Halley

Listening to Auroras
We had a variety of masts at Halley. The met-masts had weather vanes and anemometers on top, the radio masts held the aerials and there were masts belonging to the upper atmospheric group who studied auroras.

The SHARE masts were a set of 16 towers which were part of a global experiment to investigate the interaction between the solar wind and the Earth's magnetic field.

This interaction occurs all the time but sometimes, after a large ejection of particles from the sun, and if it was night time, we could see this interaction which is called the aurora.

In the North Pole it is called the Aurora Borealis, in the South Pole it is called the Aurora Australis.
