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.

Larger Role for Shallow Intermediate Waters in Ocean Circulation

by S. E. Pratt 24 March 20207 March 2023

Water masses formed off southeastern Greenland may contribute more than previously thought to the variability of the Atlantic Meridional Overturning Circulation, which strongly influences global climate.
