Dissecting Ocean Dynamics in Greenland Fjords
Researchers explored the patterns and drivers of variability in fjords linking the Greenland Ice Sheet and the Atlantic Ocean using numerical simulations and in situ observations.
The Bottom of the Arctic Is Blooming
Researchers found phytoplankton hidden on the Arctic seafloor, hinting at a cascade of effects on the local ecology and carbon cycle.
Measuring the Ins and Outflows of Estuaries
Scientists modeled monitoring schemes in three different estuaries to determine instrument layouts that could effectively and efficiently measure exchanges of salt water and freshwater.
Looking to the Sky for Better Tsunami Warnings
Pairing navigation satellites and CubeSats could provide earlier, more accurate warnings of approaching tsunamis and other impacts of extreme events.
Fluid Dynamics of Tiny, Ancient Marine Animals
Water flow simulations using 3D models of fossils yield new clues to the evolution of organisms known as medusozoans.
Respiration Quotient Variability and Ocean Oxygen Levels
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.
