Abrupt changes in deep Atlantic circulation during the transition to full glacial conditions [PDF]
Six Ocean Drilling Program (ODP) sites, in the Northwest Atlantic have been used to investigate kinematic and chemical changes in the ‘Western Boundary Undercurrent’ (WBUC) during the development of full glacial conditions across the Marine Isotope Stage

Mechanisms of warm-water intrusions onto the West Spitsbergen Shelf during winter [PDF]
The West Spitsbergen Current, flowing northward along the continental slope in the eastern Fram Strait, represents a key pathway for warm Atlantic Water entering the Arctic Ocean.

Extreme deepening of the Atlantic overturning circulation during deglaciation [PDF]
Glacial terminations during the late Pleistocene epoch are associated with changes in insolation. They are also punctuated by millennial-scale climate shifts, characterized by a weakening and subsequent strengthening of the Atlantic meridional ...

Oxygen isotope ecology of recent planktic foraminifera at the central Walvis Ridge (SE Atlantic) [PDF]
Above the Walvis Ridge, in the SE Atlantic Ocean, we collected living plantkic foraminifera from the upper water column using depth stratified plantkon tows. The oxygen isotope composition (

The downward spiralling nature of the North Atlantic Subtropical Gyre
By tracing northward flowing Atlantic water, here the authors show that before this water leaves the North Atlantic Subtropical Gyre and continues northwards, most of it circulates around the gyre while becoming denser through mixing.

Large ensemble simulations project an intensification of the South Atlantic subtropical gyre with reduced water supply to the North Atlantic due to a weakening of the Atlantic meridional overturning circulation and changes in atmospheric forcing.

Transition Paths of North Atlantic Deep Water
Abstract Recently introduced in oceanography to interpret the near-surface circulation, transition path theory (TPT) is a methodology that rigorously characterizes ensembles of trajectory pieces flowing out from a source last and into a target next, i.e., those that most productively contribute to transport. Here we use TPT to frame, in a statistically

Enhanced 20th-century heat transfer to the Arctic simulated in the context of climate variations over the last millennium [PDF]
Oceanic heat transport variations, carried by the northward-flowing Atlantic Water, strongly influence Arctic sea-ice distribution, ocean–atmosphere exchanges, and pan-Arctic temperatures.
