Dear MEL Topic Readers,
Unique 1.5m year-old ice to be melted to unlock mystery
An ice core is a core sample removed from an ice sheet in Antarctica or
a high mountain glacier. Analyzing an ice core is like riding on a time machine.
It contains ice formed hundreds of thousands to over a million years ago. From deep
inside Antarctica’s ice sheet, 2.8km of ice core was extracted, chopped into one-meter
blocks, and transported to research facilities in Germany, Switzerland, and the
UK. Researchers are now analyzing them to learn wind patterns, temperature, sea
levels, and more, hoping to identify the cause of a mysterious change in
climate that occurred 800,000 to 1.2 million years ago when the planet's
glacial cycles suddenly changed. Very careful handling is required in order not
to have the ice cores affected by today’s environment.
Read the article and learn about what ice cores from Antarctica could
reveal about the climate of a million years ago.
