Millennial and centennial CO2 release from the Southern Ocean during the last deglaciation

Jimin Yu et al.

Summary: Atmospheric CO2 can critically influence the global climate, but the mechanisms of carbon transfer between the oceanic and atmospheric reservoirs are poorly understood. Recent studies suggest that during the deglaciation, there was a net release of CO2 in the Atlantic sector of the Southern Ocean, contributing to the rise in atmospheric CO2. Additionally, the expansion of Antarctic Intermediate Water was found to be responsible for the rise in atmospheric CO2 during the Bolling warming event.

Early deglacial CO2 release from the Sub-Antarctic Atlantic and Pacific oceans

R. Shuttleworth et al.

Summary: Research indicates that there were two transient intervals of pronounced atmospheric CO2 rise during the last deglaciation, possibly due to deep ocean carbon release from the Southern Ocean and a decline in global efficiency of the biological carbon pump. The Sub-Antarctic region experienced upwelling of carbon-rich water during Heinrich Stadial 1, contributing to the initial increase in atmospheric CO2, but there was no significant outgassing of deep ocean carbon from this region during other periods.

OceanSODA-ETHZ: a global gridded data set of the surface ocean carbonate system for seasonal to decadal studies of ocean acidification

Luke Gregor et al.

Summary: This study presents a global dataset of surface ocean parameters, including dissolved inorganic carbon, total alkalinity, partial pressure of CO2, pH, and saturation state with respect to mineral CaCO3, from 1985 to 2018. The dataset, named OceanSODA-ETHZ, was created by extrapolating surface ocean observations using a newly developed method.
