A sensitive underwater microphone captures the sounds of methane, a potent greenhouse gas, escaping into waters off the coast of Oregon. Using this sound, researchers can estimate the bubbles’ sizes.
Despite different wind forcing and air-sea heating conditions, the surface layer energetics of two Western Boundary Current systems in different ocean basins are surprisingly similar.
Lacking light and energy, under-seafloor microbes rely on ancient organic materials to survive.
Subsurface measurements of nitrogen and oxygen isotope ratios in nitrate reveal a predominantly southern hemisphere supply of nitrate to the equatorial Pacific.
Researchers probe millennia-old deep-ocean sponges for links between ocean nutrients and climate.
Understanding changing conditions in the south polar oceans during the warm late Pliocene period may help predict the impact of contemporary warming.
Early-career scientists aboard the 2016 UNOLS Chief Scientist Training Cruise explored recently reactivated underwater methane seeps in the San Diego Trough.
Carbon isotope data suggest an alternative source of nutrients to the Eastern Equatorial Pacific during glacial periods.
Researchers use dissolved silicon concentrations to map out how currents may have changed millennia ago in the Pacific.
Laboratories outside Japan have validated the results. Marine radioactivity levels from the nuclear disaster have fallen, but questions remain years after the meltdown.
