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.

Exploring Ocean Turbulence: 2016 Sloan Fellow Ryan Abernathey
When you examine the behavior of the global oceans closely—really closely, at scales smaller than 100 kilometers—eddies and jets and fronts start to appear. For Ryan Abernathey, this is where ocean physics gets interesting.

A New Tool for Coastal Planners Preparing for Sea Level Rise
Globally, the tool estimates at least 11 inches of sea level rise this century with ambitious efforts to lower greenhouse gas emissions and as much as 52 inches if greenhouse gas emissions continue to grow unchecked.

How Does Earth’s Continental Crust Form? A New Bottom-Up Theory
Scientists have long believed that continental crust forms in volcanic arcs. The lingering question has been how exactly that happens.

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
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.

Climate Change Isn’t Just a 21st Century Problem
Humans have been burning fossil fuels for only about 150 years, yet that has started a cascade of profound changes that at their current pace will still be felt 10,000 years from now, a new study shows.

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.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
