Wind-driven upwelling in the ocean around Antarctica helps regulate the exchange of carbon dioxide (CO2) between the deep sea and the atmosphere, as well as the supply of dissolved silicon to the euphotic zone of the Southern Ocean. Diatom productivity south of the Antarctic Polar Front and the subsequent burial of biogenic opal in underlying sediments are limited by this silicon supply. We show that opal burial rates, and thus upwelling, were enhanced during the termination of the last ice age… 
Southern Ocean contribution to both steps in deglacial atmospheric CO2 rise
The results lend support for the release of sequestered CO2 from the deep ocean to surface and atmospheric reservoirs during the last deglaciation, although further work is required to pin down the detailed carbon transfer pathways.
On the connection between upwelling , opal deposit rates and atmospheric CO 2 concentration
The theory that the Southern Ocean dominates the carbon exchange between the sea and the atmosphere has been challenged in the recent years. Strong evidence for this theory has been the opal flux
Antarctic Intermediate Water penetration into the Northern Indian Ocean during the last deglaciation
Deglacial pulses of deep-ocean silicate into the subtropical North Atlantic Ocean
A record of biogenic opal export from a coastal upwelling system off the coast of northwest Africa that shows pronounced opal maxima during each glacial termination over the past 550,000 years is reported, suggesting an alternative mechanism for the deglacial CO2 release.
Ventilation of the Deep Southern Ocean and Deglacial CO2 Rise
Radiocarbon data from the Southern Ocean indicate that the deep water circulating around Antarctica was about twice as old relative to the atmosphere as it is today, a condition considered indicative of carbon dioxide accumulation and storage.
Larger CO2 source at the equatorial Pacific during the last deglaciation
This work presents seawater pH and pCO2 variations from fossil Porites corals in the mid equatorial Pacific offshore Tahiti based on a newly calibrated boron isotope paleo-pH proxy, indicating an expanded zone of equatorial upwelling and resultant CO2 emission which may be derived from higher subsurface dissolved inorganic carbon concentration.
Southern Ocean upwelling, Earth’s obliquity, and glacial-interglacial atmospheric CO2 change
High-resolution diatom-bound nitrogen isotope measurements from the Indian sector of the Antarctic Zone reveal three modes of change in Southern Westerly Wind–driven upwelling, each affecting atmospheric CO2, which can explain the lag of atmospheric carbon dioxide behind climate during glacial inception and deglaciation.
Holocene dynamics of the Southern Hemisphere westerly winds and possible links to CO2 outgassing
The Southern Hemisphere westerly winds (SHW) play an important role in regulating the capacity of the Southern Ocean carbon sink. They modulate upwelling of carbon-rich deep water and, with sea ice,
Deep ocean ventilation, carbon isotopes, marine sedimentation and the deglacial CO 2 rise
Abstract. The link between the atmospheric CO2 level and the ventilation state of the deep ocean is an important building block of the key hypotheses put forth to explain glacial-interglacial CO2


The role of Southern Ocean mixing and upwelling in glacial-interglacial atmospheric CO2 change
Decreased ventilation of the Southern Ocean in glacial time is implicated in most explanations of lower glacial atmospheric CO2. Today, the deep (>2000 m) ocean south of the Polar Front is rapidly
Contribution of Southern Ocean surface-water stratification to low atmospheric CO2 concentrations during the last glacial period
The nitrogen-isotope record preserved in Southern Ocean sediments, along with several geochemical tracers for the settling fluxes of biogenic matter, reveals patterns of past nutrient supply to
Midlatitude westerlies, atmospheric CO2, and climate change during the ice ages
[1] An idealized general circulation model is constructed of the ocean's deep circulation and CO2 system that explains some of the more puzzling features of glacial-interglacial CO2 cycles, including
Evidence for northward expansion of Antarctic Bottom Water mass in the Southern Ocean during the last glacial inception
[1] We investigated deep water changes in the Southern Ocean during the last glacial inception, in relationship to surface hydrology and global climatology, to better understand the mechanisms of the
Radiocarbon Variability in the Western North Atlantic During the Last Deglaciation
The deep-ocean record supports the notion of a bipolar seesaw with increased Northern-source deep-water formation linked to Northern Hemisphere warming and the reverse, and the more frequent radiocarbon variations in the intermediate/deep ocean are associated with roughly synchronous changes at the poles.
Atmospheric CO2 concentrations over the last glacial termination.
The similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations.
Marine Radiocarbon Evidence for the Mechanism of Deglacial Atmospheric CO2 Rise
The timing of intermediate-water radiocarbon depletion closely matches that of atmospheric carbon dioxide rise and effectively traces the redistribution of carbon from the deep ocean to the atmosphere during deglaciation.
Glacial/interglacial variations in atmospheric carbon dioxide
A version of the hypothesis that the whole-ocean reservoir of algal nutrients was larger during glacial times, strengthening the biological pump at low latitudes, where these nutrients are currently limiting is presented.
Evidence from the high‐latitude North Atlantic for variations in Antarctic Intermediate water flow during the last deglaciation
We present evidence that the characteristic chemical signature (based on coupled benthic foraminiferal Cd/Ca and δ13C) of Antarctic Intermediate waters (AAIW) penetrated throughout the intermediate
