Oceanographer Dr. Povl Abrahamsen, saying: "My name is Povl Abrahamsen. I'm an oceanographer at the British Antarctic Survey. At the moment I'm on the royal research ship James Cook, about 90 nautical miles south of south Georgia. And behind me is iceberg A68p. Iceberg A68 has broken into lots of bits, and A68p is the most recent one to be named. And even though it's no longer nearly as big as it was, it's still about 100 square kilometres. We're here to study the effect of the iceberg on the ocean ecosystem around South Georgia."

Robots are being used to assess if the bergs are damaging ecosystems

Oceanographer Dr. Povl Abrahamsen, saying: "We've deployed some robotic underwater gliders which will stay here measuring the ocean beneath us for months after we leave."

Scientists say sights like this will become more common

amid rising global temperatures
