New findings suggest that rare events underlie a global inverse relationship between primary production of organic carbon in the upper ocean and the fraction that is exported to the deep sea.

Effects of Variability in Atlantic Ocean Circulation
There is strong evidence that the Atlantic meridional overturning circulation plays an essential role in Atlantic multidecadal variability and associated climate impacts.
New Perspectives on 2,000 Years of North Atlantic Climate Change
A review of recent research advancements takes a deep dive into North Atlantic ocean circulation and its potential role in historical climate shifts.
In a Spin: New Insights into the Beaufort Gyre
A new special collection in JGR: Oceans presents results from studies of the Beaufort Gyre, an oceanic circulation system in the Arctic that has far-reaching influence on the global climate.
North Atlantic Circulation Patterns Reveal Seas of Change
New evidence suggests the eastern Atlantic may be the site of major overturning.
Atlantic Overturning Circulation Questions Abound
International AMOC Science Meeting; Miami, Florida, 24–27 July 2018
Waves of Deadly Brine Can Slosh After Submarine Landslides
Brine pools—hypersaline, low-oxygen waters deadly to many forms of ocean life—can experience waves hundreds of meters high when hit by a landslide, potentially overspilling their deep-sea basins.
Climate Change and Sea Level Rise in the Mediterranean
1st National Workshop on Climate Change and Sea Level Rise in the Mediterranean; Rome, Italy, 5–6 July 2018
How Do Turbidity Currents Accelerate?
Flume experiments show that a self-reinforcing cycle can strengthen the currents responsible for transporting large amounts of sediment to the deep oceans.
Radionuclide Data from GEOTRACES Improve Particle Flux Estimates
New measurements of multiple radionuclides in the Atlantic Ocean offer a robust constraint on the sinking flux of particles and associated vertical fluxes of biogeochemically important elements.
