Arctic Salinity Pushes the AMOC Swing

by Kristopher B. Karnauskas 3 August 202222 December 2022

A model of the Atlantic Meridional Overturning Circulation (AMOC), pioneered by Henry Stommel over 60 years ago, can exhibit realistic cyclic behavior if the role of Arctic salinity is included.

Landfalling Hurricanes Intensify Due to Coastal Downwelling

by Suzana Camargo 26 July 202221 September 2022

Hurricane winds can lead to coast downwelling, which brings warmer surface water near the coast and can contribute to the intensification of the landfalling hurricane.

Wind Stress is not the Ceiling of Momentum Flux to the Ocean

by Lei Zhou 15 February 202116 September 2022

The ocean is mainly driven by wind stress, but simultaneous observations show that the gain of momentum flux by the ocean can be larger than the wind stress due to the influence of ocean waves.

A New Way to Fingerprint Drivers of Water Cycle Change

by Terri Cook 15 October 202020 July 2022

Simulations of tropical ocean convection help distinguish climate effects resulting from large-scale changes in atmospheric circulation from those resulting from higher temperatures.

Jellies Transfer a Significant Amount of Carbon to the Deep Ocean

by Rachel Fritts 14 October 202016 March 2023

Jellyfish and sea salps aren’t getting the credit they deserve for their role in ocean carbon cycling, according to a new study.

Below the Great Pacific Garbage Patch: More Garbage

by Mara Johnson-Groh 4 June 20201 February 2023

New research is finding there’s more to marine debris than just what appears near the ocean surface, including tons of microplastics extending hundreds of meters into the deep.
