Assessing improvements in global ocean pCO₂ machine learning reconstructions with Southern Ocean autonomous sampling [PDF]

Biogeosciences
The Southern Ocean plays an important role in the exchange of carbon between the atmosphere and oceans and is a critical region for the ocean uptake of anthropogenic CO2.

Gene flow in the Antarctic bivalve Aequiyoldia eightsii (Jay, 1839) suggests a role for the Antarctic Peninsula Coastal Current in larval dispersal

Royal Society Open Science, 2020
The Antarctic Circumpolar Current (ACC) dominates the open-ocean circulation of the Southern Ocean, and both isolates and connects the Southern Ocean biodiversity. However, the impact on biological processes of other Southern Ocean currents is less clear.

Modelling radiocarbon uptake by the Southern Ocean [PDF]

, 1995
The circulation of the Fine Antarctic Resolution Model (FRAM) is being applied in the development of an off-line and radiocarbon validated tracer model for the Southern Ocean.

Southern Ocean Biological Pump Role in Driving Holocene Atmospheric CO2: Reappraisal

Geophysical Research Letters
Changes in Southern Ocean biological pump efficiency are frequently invoked as a source of glacial/interglacial CO2 variability. It was recently suggested that Southern Ocean biological pump weakening also contributed to Holocene CO2 increase.

The Southern Ocean carbon sink has been overestimated in the past three decades

Communications Earth & Environment
Employing machine learning methods for mapping surface ocean pCO2 has reduced the uncertainty in estimating sea-air CO2 flux. However, a general discrepancy exists between the Southern Ocean carbon sinks derived from pCO2 products and those from ...

Interaction of AMOC and intrinsic multidecadal Southern Ocean variability [PDF]

Ocean Science
A strongly-eddying version (0.1° horizontal resolution) of the Parallel Ocean Program (POP) shows pronounced intrinsic multidecadal variability in the Southern Ocean, the so-called Southern Ocean Mode (SOM).

Glacial heterogeneity in Southern Ocean carbon storage abated by fast South Indian deglacial carbon release

Nature Communications, 2020
A Southern Ocean influences on the carbon cycle is considered a key component of deglacial changes. Here, the authors show spatial differences in glacial Southern Ocean carbon storage that dissipated rapidly 14.6 kyr ago, revealing a South Indian Ocean ...

Climatic modulation of surface acidification rates through summertime wind forcing in the Southern Ocean

Nature Communications, 2018
The Southern Annular Mode is a dominant climate variability mode in the Southern Ocean. Using observational data, the authors show a strong climatic modulation of ocean acidification via Southern Annular Mode -related winds.
