Respiration quotients in the Atlantic and Pacific Oceans reflect different water temperature, nutrient stress and phytoplankton community structure, important for regional carbon and oxygen cycling.

Salt Spray May Stifle Lightning over the Sea
New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.
When Winds and Currents Align, Ocean Mixing Goes Deep
Slantwise convection in the Irminger Sea off Greenland appears to mix ocean water to deeper depths than previously thought, representing an important contribution to Atlantic overturning.
A Close Look at Melting Below Antarctica’s Largest Ice Shelf
Radar data reveal where, when, and how fast the base of the Filchner-Ronne Ice Shelf has been losing mass in recent years.
An Inclusive Approach to Oceangoing Research
The bread and butter of oceanography, sea voyages rarely include minoritized communities and nonscientists. The Inclusion Mission wants to change that.
Can Anelastic Attenuation of Oceanic Mantle be Reliably Measured?
A new study demonstrates that robust anelastic attenuation measurements can be made across ocean bottom seismic arrays at different locations using surface wave array analysis.
Scientists Tune In to Blue Whale Feeding Rhythms
New acoustic sensing technology is allowing scientists to track blue whale movements in real time, a breakthrough that could help save whales’ lives.
Machine Learning Looks Anew at Isotope Ratios in Oceanic Basalts
While past attempts to define isotopic endmembers and assign them a geodynamic significance ended in controversy, a machine-learning clustering algorithm offers a solution to this classical problem.
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
How do Bob and Tom Eddies Meet, Pair-Spin, and Twist?
Autonomous float data reveal that mergers of two eddies, known to have spiraling subducting water surrounding each other, happens more frequently than previously thought.
