 Antarctica is a freezing cold place. It's covered in snow and ice but around volcanoes in Antarctica the steam melts the ice and in fact the steam can create amazing cave systems beneath the glaciers and it's in these caves that we've gone looking for evidence of life. The caves that we know best are on Mount Erebus, a volcano on Ross Island in Antarctica and some of those caves can reach 20 or 25 degrees Celsius inside so you could comfortably wear a t-shirt in there. Our study gives us a really exciting tantalizing glimpse of the sorts of plants and animals that might live beneath the ice in Antarctica. Some of the DNA evidence that we found suggests that maybe there are things living in these caves that we know nothing about there could even be new species. So obviously finding DNA evidence that there are plants and animals in the caves is not enough to say for sure that those plants and animals are there so the next step is to go and have a really good look and see whether we can find communities living beneath the ice in Antarctica.
