89022
My job was to work with the meterology team. Every three hours we had to record the weather, cloud cover and visibility. The data was sent back to the Met Office in Bracknell to be used in their forecasting charts.

One of the hardest jobs was launching the weather balloon everyday which had to be launched no matter what the conditions. Battling with a gynormous helium balloon in gale force winds is quite alarming.

One of my favourite jobs was measuring the ozone above the station. It was scientists at the British Antarctic Survey working with data collected from Halley that discovered the hole in the ozone layer. My boss Jon was one of the scientists.

Every couple of days we had to go out and measure the snow stakes. These were 10 poles stuck in the ground about 100 meters from the Met platform and used to measure snow accumulation. One day in the middle of winter when it was pitch black outside I spent over an hour looking for the poles! Over the next few weeks I tried numerous and ineffective schemes to light up the poles - like attaching reflective tape which got covered in rime. I was very pleased when the sun finally came back in mid-August.

Meteorologically speaking Halley was classed as a ship and given the code 89022. Sometimes we felt like a ship. The whole base was moving North 2m a day and we rose and sank with the tides. On very windy days the platforms would sway about and I felt quite queezy.

Ozone
The "ozone layer" is a layer of ozone which covers the planet and protects us from harmful UV light from the sun. In springtime in Antarctica the conditions are perfect for CFCs to destroy the ozone. In springtime almost 2/3rds of the ozone over Antarctica is destroyed and the "ozone hole" forms.

At Halley we measured the amount of UV light that reached the ground to calculate how much ozone was above us. This was particularly important in spring when the hole formed and people could get badly sunburnt.
