Antarctica is the iciest place on Earth, but its icy cover is deceiving. All this ice is on the move. Find out how ice and rocks hold clues to Antarctica's climate past in this video.
Most of Antarctica's history is buried in layers of rock, deep beneath the ice. Rock cores that ANDRILL retrieves are packed with evidence. But once found, how do geologists read climate history embedded in rock? Watch the following video to find out.
Take a trip to Earth's freezer -- the coldest, windiest, driest, place on Earth. How long has Antarctica been like it is today? That's what polar researchers want to find out. Meet ANDRILL, the Antarctic drilling team in this video.
What's normal in climate cycles? In a warming world, ice is beginning to break apart in Antarctica. Has it happened before -- and how does it affect sea level? In this NET exclusive video, geologists and climate modelers examine ANDRILL cores, Earth's orbit, greenhouse gases, and evidence in New Zealand.
ANDRILL's rock cores reveal evidence of changing climate and ice conditions in Antarctica's past. Within the cores are ocean fossils -- some easily seen, others microscopic. Watch this video to learn how the biggest discoveries come from the tiny clues: diatoms and forams.
