British Antarctic Survey support field expedition to James Ross Island

British Antarctic Survey (BAS) will support a team of scientists from the Universities of Leeds and Aberystwyth as they embark on an ambitious three-month Antarctic expedition. Their fieldwork aims to uncover information about how the glaciers and ice sheets of the north-eastern Antarctic Peninsula behaved in past climates, and what we can expect in the future.

Alan Hill, an experienced BAS field assistant, will accompany three British scientists as they set sail for James Ross Island aboard the Royal Research Ship Ernest Shackleton, which lies just off the Antarctic Peninsula. In a quest to learn more about the climate history of the region the team is heading to part of the coldest, windiest, highest and driest continent on Earth where they will live and work together in an isolated and challenging environment. They will be heavily laden with equipment including four quad bikes, two trailers, scientific equipment, tents and enough food and fuel to last three months.

The Antarctic Peninsula has experienced above average warming over the past half-century, with around a 2.5°C temperature increase since 1950. This warming is causing glaciers and ice shelves to melt, releasing large volumes of fresh water into the oceans which not only raises sea level, but also influences deep sea circulation and regional climate.

However, scientists do not fully understand the relationship between air and sea temperature, and the melting of ice. Therefore it is difficult for them to assess whether the melting being observed at the moment is unprecedented in the context of geological time.

To address these outstanding questions, the team will collect samples of rock to date their exposure to cosmic radiation and thus to analyse how the glaciers and ice have retreated since the last ice age, around 20,000 years ago.

Lead researcher Professor Neil Glasser, from the University of Aberystwyth said, 'The collapse of Antarctic ice shelves is largely thought to be caused by warming of the atmosphere, but it appears that changes in sea temperature and ice-shelf structure are also important. With the climate expected to warm in the future, it is important for us to understand how Antarctic glaciers and ice shelves behaved in the past so we can predict how they will react in years to come if temperatures continue to rise.'

Dr Jonathan Carrivick from the University of Leeds said, 'We're expecting the expedition to be very exciting and challenging due to a quite different style of operations. Normally when researchers work in Antarctica they operate from a research ship or at an established station, whereas we will be dropped off with all our kit and left for two months with just radio contact to the rest of the world.'

The team will spend two months collecting around 100 boxes of rock samples, which they will bring back to Britain to study in a laboratory. They will analyse the rock mineralogy, geochemistry and isotopic character to determine when they were first exposed to cosmic rays; to calculate when ice cover disappeared from that particular site. They are also planning to map a 600km2 ice-free area of the island to allow them to generate a 3D terrain model.
