Yesterday we sent a re-entry camera down to the seafloor, which meant it's time for shrunken cups! Decorated by South Kingstown HS and Curtis Corner Middle School, as well as #EXP382 scientists, these cups look a bit different than when they started out... #IcebergAlley @NSF_GEO pic.twitter.com/iNWXVYY5JS

The Antarctic ice sheet is 34 million years old. But Antarctica hasn't always been icy – in fact, 100 million years ago, it was covered in forests! #EarthDay @NSF_GEO #EXP382 #IcebergAlley #Antarctica pic.twitter.com/BOecjGEyZ3

During ice ages, the deep ocean trapped more CO2, and lowered atmospheric CO2 by about a third. As recently as 18,000 years ago, atmospheric CO2 was only 180ppm compared with 280ppm around 200 years ago. And today, of course, it's much higher – more than 400ppm! #EarthDay
