Circumpolar Effects of a Velocity‐Restoring Scheme for Antarctic Fast Ice on Shelf Waters and Ice Shelf Melt Simulated by NEMO4‐SI3

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Dense water formation in the Southern Ocean plays a key role in the global ocean overturning circulation, affecting the distribution of heat, carbon, oxygen, and nutrients. Fast ice stays immobile while blocking sea ice flow, favoring the opening of coastal polynyas, where intense air‐sea exchanges drive sea ice production and ocean ...

Sediment ²³¹Pa/²³⁰Th as a recorder of the rate of the Atlantic meridional overturning circulation: insights from a 2-D model [PDF]

Ocean Science, 2010
A two dimensional scavenging model is used to investigate the patterns of sediment 231Pa/230Th generated by the Atlantic Meridional Overturning Circulation (AMOC) and further advance the application of this proxy for ocean paleocirculation studies.

Reassessing the Role of the Antarctic Slope Current in Poleward Ocean Heat Transport

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The Antarctic Slope Current (ASC) is often considered a barrier to the poleward transport of Circumpolar Deep Water (CDW), yet its vast extent has hindered circumpolar analysis of this relationship. Here, we use a high‐resolution global ocean‐sea ice model that resolves the slope current to assess the link between variability in the ASC and ...

The South Atlantic Meridional Overturning Circulation at 34.5°S in 2017 and 2022

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract The Atlantic Meridional Overturning Circulation (AMOC) at 34.5°S is investigated using hydrographic data from two research cruises conducted in 2017 and 2022. Data from the South AMOC Basin‐wide Array (SAMBA) are used to close the 2022 section.

A model study of decadal climate variability and predictability associated with the Atlantic meridional overturning circulation

, 2012
This study addresses the decadal variability and predictability of the Atlantic Meridional Overturning Circulation (AMOC), and associated key variables, in two IPCC-class climate models.

Evidence for Atlantic Ocean forcing the atmosphere and the negative role of model bias

Communications Earth & Environment
There is agreement on how the North Atlantic Oscillation forces the Atlantic Meridional Overturning Circulation, but the existence of a reversed interaction is widely disputed.

Simulated Ocean Oxygen Under Miocene Boundary Conditions

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Miocene Climatic Optimum (MCO; 16.9–14.7 Ma) was a warm interval with atmospheric CO2 ${\text{CO}}_{2}$ comparable to end‐of‐21st‐century projections under intermediate emission scenarios. Proxy records indicate the Oxygen Minimum Zone (OMZ) in the Eastern Tropical Pacific (ETP) was small or non‐existent during the MCO, expanding only when

Abrupt changes in deep Atlantic circulation during the transition to full glacial conditions [PDF]

, 2013
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

Iceberg Freshwater Transport Alleviates Future Weakening of Antarctic Bottom Water Formation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intensification of calving in a warmer future climate would result in production of more Antarctic icebergs, and iceberg freshwater flux would play a more consequential role in ice‐climate interactions. Distribution of iceberg freshwater flux under future climate scenarios, however, has not been assessed with full consideration of changes and ...

Effects of atmospheric dynamics and ocean resolution on bi-stability of the thermohaline circulation examined using the Grid ENabled Integrated Earth system modelling (GENIE) framework [PDF]

, 2007
We have used the Grid ENabled Integrated Earth system modelling (GENIE) framework to undertake a systematic search for bi-stability of the ocean thermohaline circulation (THC) for different surface grids and resolutions of 3-D ocean (GOLDSTEIN) under a 3-
