Tokyo - Japanese researchers said on Tuesday they had dug up ice in the Antarctic Ocean estimated to be one million years old that could give more clues about climate and environmental changes.
It is believed to be the oldest ice retrieved after an 800 000-year-old block collected by European scientists in 2004.
The Japanese mission headed by the National Institute of Polar Research drilled down more than 3 000 metres in the Antarctic Ocean to pull out the slab deep in the ice core.
The group will bring the ice back to Japan in April for research.
"We need further analysis but the ice is expected to clarify things such as climate and environmental change or the evolution of microbes over the past million years," said Yoshiyuki Fujii, director general at the polar institute.
"Finding out the cycle and rhythm of climate change in the past will help to forecast the future," he said.
The research group took three years to drill to the ice at Japan's Dome Fuji Station.
