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.
When Oceans Leak
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.
After weeks of anticipation, permission arrived just in time to core off Mozambique. Sidney Hemming and her team of scientists aboard the JOIDES Resolution are excited about what they might learn from the ocean sediment.
Trying to drill sediment cores while the ship rides large ocean swells off the coast of Africa isn’t easy, but it’s paying off for science, writes Sidney Hemming.
The team aboard the JOIDES Resolution just finished at their first coring site off southern Africa. The first results? “Awesome.” Sidney Hemming describes the process in words and photos.
Sidney Hemming and her team have started examining their first sediment core from off southern Africa. It appears to contain about 6 million years of history.
As they get to know their ship, the scientists aboard the JOIDES Resolution prepare to drill their first sediment cores along the Natal Valley off the coast of southern Africa.
