Tracking Down Hydrothermal Vents

Scattered along the barren ocean floor lie uncounted hydrothermal vent sites—oases of hot, chemical-rich, life-nurturing fluids. These oases are a submarine version of Yellowstone National Park.

Reading revealing reversals (or charting magnetic patterns to map history)

This is the latest in a series of dispatches from scientists and education officers aboard the Schmidt Ocean Institute’s R/V Falkor. The crew is on 36-day research trip to study Tamu Massif, a massive underwater volcano, located 1,500 kilometers (930 miles) east of Japan in the Shatsky Rise. Read more posts here.

Observations of Maggie’s data
Our magnetometer has been playfully named “Maggie,” but what she accomplishes is pure work, not recreation. Maggie records how much the Earth’s magnetic field is perturbed by crustal magnetism. With these data sets, a pattern of geomagnetic reversals along the ocean bottom is shown. These reversal patterns can be used in assessing age distribution of the ocean floor.

New research identifies areas of global ocean most vulnerable to ocean acidification

New research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. The study identifies the Arctic and Antarctic oceans, and the upwelling ocean waters off the west coasts of North America, South America and Africa as regions that are especially vulnerable to ocean acidification.

Gulf Stream ring water intrudes onto continental shelf like “Pinocchio’s Nose”

Ocean robots installed off the coast of Massachusetts have helped scientists understand a previously unknown process by which warm Gulf Stream water and colder waters of the continental shelf exchange. The process occurs when offshore waters, originating in the tropics, intrude onto the Mid-Atlantic Bight shelf and meet the waters originating in regions near the Arctic. This process can greatly affect shelf circulation, biogeochemistry and fisheries.
