Icebreaker Shirase leaves for another voyage to Antarctic continent

Nov 13 (Japan Times) - The icebreaker Shirase, operated by the Maritime Self-Defense Force, left Tokyoâ€™s Harumi pier for Antarctica on Sunday.

Most members of the 59th Antarctic expedition team will board the ship in Australia on Nov. 28. The Shirase will carry a total of about 180 crew members.

In 2007, a Japanese mission sampled 720,000-year-old ice at the nation's Dome Fuji Station in inland Antarctica by drilling through the ice sheet to a depth of 3,035 meters. The team heading there at the end of the month will select a new drilling point, with the aim of collecting even older ice.

A European expedition team in 2004 collected Antarctic ice dating back some 800,000 years. The coming Japanese mission will try to extract even older ice to set a new world record.

Scientists expect that an analysis of Antarctic ice will allow them to better understand climate change in the past and predict future global warming.

The 59th team will also carry on atmospheric and marine observation, and research on penguins and other creatures on Antarctica.
