    Finding Microfossils off Southern Africa

    Expedition 361’s newest sediment cores brought up spectacular foraminifera—translucent, glassy and “very pretty” throughout the ocean sediment.

  • A Surprise from the Zambezi River

    A Surprise from the Zambezi River

    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.

  • Mozambique Core Brings Up 7 Million Years of Climate History

    Mozambique Core Brings Up 7 Million Years of Climate History

    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.

  • We’re Headed for Mozambique!

    We’re Headed for Mozambique!

    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.

  • Trials & Tribulations of Coring the Agulhas Plateau

    Trials & Tribulations of Coring the Agulhas Plateau

    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.

  • Sailing into a Storm as We Head for the Agulhas Plateau

    Sailing into a Storm as We Head for the Agulhas Plateau

    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.

  • 6 Million Years of Sediment, Studded with Tiny Fossils

    6 Million Years of Sediment, Studded with Tiny Fossils

    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.

  • Gearing Up for Our First Cores

    Gearing Up for Our First Cores

    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.

  • Setting Off for Two Months at Sea

    Setting Off for Two Months at Sea

    Sidney Hemming and the scientists aboard the JOIDES Resolution conduct the final preparations for their research cruise off southern Africa and introduce a girls’ school group from Mauritius to science at sea.
