A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.

Driven by changing climate, a uniquely resilient organism is taking over the Arabian Sea, disrupting food chains, fisheries, oil refineries, and water desalination plants.

The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important. It is the only one to flow clear around the globe without getting diverted by any landmass, sending up to 150 times the flow of all the world’s rivers clockwise around the frozen continent.

Tiny microbes called phytoplankton live beneath the ocean’s surface, producing oxygen that is essential to human survival. A new study sheds light on how these all-important diatoms survive and thrive under difficult conditions.

The gift will be used to fast-track innovative high-risk, high-reward projects aimed at delivering science-based solutions to address the challenges of climate change.

Three scientists explain what they’re learning about the ocean’s changing conditions. These discoveries will contribute to the sustainable management and conservation of marine resources, helping to secure food for current and future generations.

More than 85 percent of the ocean floor remains unmapped, leaving us in the dark about much of the earth’s topography. A global, non-profit effort will try to remedy that by 2030. The effort will affect everything from climate research and weather prediction to mineral resource exploration and fisheries.

Figuring out how far sea level rose during past warm periods in Earth’s history starts with a walk on the beach, a keen eye for evidence of ancient shorelines, and a highly accurate GPS system. The math isn’t as simple as subtracting the distance from the old shoreline to the water’s edge, though. As massive ice sheets retreated during past ice ages, their weight on the land below lifted and the land rebounded. On longer time scales, circulation within the Earth’s mantle has changed the shape and height of the crust, as well.

Along the walls of Oceanographer Canyon, fish dart in and out of colorful anemone gardens and sea creatures send up plumes of sand and mud as they burrow. Bill Ryan, an oceanographer at Columbia University’s Lamont-Doherty Earth Observatory, watched the scenes through the windows of a mini research submarine in 1978 as he became one of the few people to explore the seafloor canyons that President Obama has now designated a national monument.

Jay Ardai was the guy you wanted in your sea ice camp after the ship left, or in the Alaska wild when your plane had mechanical trouble. He earned his reputation in remote locations like these as a super-technician who could fix anything using whatever he could find.

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, who was just awarded a 2016 Sloan Research Fellowship, this is where ocean physics gets interesting.
