I'm an oceanographer at the British Antarctic Survey the moment I'm on royal Research Ship James Cook, about 90 nautical miles south of South Georgia.

And behind these iceberg a 68 p.

The iceberg, a 68 has broken into lots of bits.

A 68 p is the most recent one that's been named.

And even though it's no longer nearly as big as it was, it's still about 100 square kilometers.

We're here to study the effect of the iceberg on the ocean.

The ecosystem around South Georgia.

Uh, we've deployed some robotic underwater gliders which will stay here measuring the ocean beneath us for months after we leave, Yeah.
