　　VOICE ONE:

　　American scientists say ice covering the ArcticSea continued to shrink last winter. The scientists say they recently found that older, thicker sea ice was increasingly replaced with new ice. The new ice is thinner and melts faster than the older ice.

　　The scientists work for the American space agency and the National Snow and IceDataCenter in Boulder, Colorado. The two government agencies have been studying ArcticSea ice from space since nineteen seventy-nine. One of the scientists says the past six years have shown the lowest Arctic sea ice cover ever measured.

　　VOICE TWO:

　　The study found an average ice cover of about fifteen million square kilometers in March. That is seven hundred thirty kilometers above the record low set three years ago. But it represents a loss of about five hundred ninety thousand kilometers from the yearly average between nineteen seventy-nine and two thousand.
