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.
