These images of the seafloor landscape around the South Sandwich Islands, in the Southern Ocean, were captured using echo-sounder technology deployed from the Royal Research Ship James Clark Ross. The technique is known as multi-beam swath bathymetry. The area mapped is approximately 600 km long by 150 km wide - almost the length of Britain.

Underwater Antarctic volcanoes discovered in the Southern Ocean

Scientists from British Antarctic Survey (BAS) have discovered previously unknown volcanoes in the ocean waters around the remote South Sandwich Islands. Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clark Ross, the scientists found 12 volcanoes beneath the sea surface - some up to 3km high. They found 5km diameter craters left by collapsing volcanoes and 7 active volcanoes visible above the sea as a chain of islands.
