Underwater volcanoes heating Antarctic waters
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 (1.86 miles) high. They found 5km (3 mile) diameter craters left by collapsing volcanoes and 7 active volcanoes visible above the sea as a chain of islands.
According to a press release from the Proceedings of the National Academy of Sciences of the United States (PNAS), "this sub-sea landscape, with its waters warmed by volcanic activity creates a rich habitat for many species of wildlife and adds valuable new insight about life on earth." (Italics added)
The research is also important for understanding what happens when volcanoes erupt or collapse underwater and their potential for creating serious hazards such as tsunamis
