This is the BBC World Service Calling Antarctica.
Hello, I'm Charis Matthews and this time in the documentary from the BBC World Service,
it's the annual edition of the Antarctic Midwinter Broadcast.
It's the BBC's programme of greetings dedicated to members
of the British Antarctic Survey overwintering in the frozen south.
For those of us in the northern hemisphere, it's mid-summer.
But for the winters in Antarctica, the temperatures are freezing.
It's dark, they're isolated far from home, and it's a time for a midwinter celebration.
So over the next half hour we'll hear from Antarctica and share messages from family and friends for the intrepid few,
working away at vital science and keeping three research stations open in the cold, cold snow.
Hello Uncle Jerry, it's Hazel here.
