In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.

“We had this magic key, this magic magnetic profile,” Pitman said. “We were able to date it and eventually use it not only as a tool that proved continental drift but a tool by which we could actually reconstruct the pattern of drift, that is the relative position of the continents, and the actual timing of the separation of the continents.”
For his pioneering work in rock mechanics and his skill at communicating earthquake science, Scholz is being honored on April 20 by the Seismological Society of America with its top award, the Harry Fielding Reid Medal.
Vicki Ferrini has spent a lot of time working on mapping the ocean floor, and now she’s sailing in the South Pacific to get a closer look.
Science at sea isn’t easy, but the benefits are huge, writes Sidney Hemming in her final post from a two-month expedition that collected millions of years of climate history in the deep-sea sediment from off southern Africa.
It turns out that studying lava flows at the bottom of the ocean uses many of the same methods as studying lava flows on other planets, writes Lamont’s Elise Rumpf.
Expedition 361’s newest sediment cores brought up spectacular foraminifera—translucent, glassy and “very pretty” throughout the ocean sediment.
Sidney Hemming and her team aboard the JOIDES Resolution got a surprise when they began taking sediment cores from their first river site off southern Africa—about 10 times more sediment than expected.
With calm seas, the JOIDES Resolution’s latest sediment core comes up with what appears to be a fantastic, cyclic climate signal that is continuous back 7 million years, writes Sidney Hemming.
