  author={Jorge L. Sarmiento and J. R. Toggweiler},
Recent ice-core measurements have revealed that the atmospheric CO2 level increased comparatively rapidly by about 70 p.p.m. at the end of the last ice age1. Here we present an ocean–atmosphere model in which changes in the productivity of high latitude surface waters (from which deep water is formed and circulated around the world's ocean) and/or in the thermo-haline overturning rate can lead to substantial changes in atmospheric partial pressure of carbon dioxide (PCO2), over a concentration… 

The polar ocean and glacial cycles in atmospheric CO2 concentration

Growing evidence suggests that the Southern Ocean CO2 ‘leak’ was stemmed during ice ages, increasing oceanCO2 storage and making the global ocean more alkaline, driving additional ocean CO2 uptake.

Cold surface ocean ventilation and its effect on atmospheric CO2

The potential for greater air-sea exchange rates in the northern Atlantic to decrease atmospheric CO[sub 2] during the ice ages is examined using a simple model of the solubility pump. This potential

The effect of temperature change of the warm surface waters of the oceans on atmospheric CO2

It is widely believed that the concentration of atmospheric CO2 is largely controlled by the high-latitude oceans, because these waters can be viewed as an outcropping of oceanic deep water. If this

Variation of atmospheric CO2 by ventilation of the ocean's deepest water

A new box model for glacial-interglacial changes in atmospheric CO2 produces lower levels of atmospheric CO 2 without changes in biological production or nutrient chemistry. The model treats the

Changes in atmospheric CO2: Influence of the marine biota at high latitude

Approximately half of the nitrogen and phosphorus entering deep waters of the contemporary ocean are transported from the surface in inorganic form as preformed nutrients. A simple model for ocean

In this study, the Vostok ice core CO2 record and the δ13C difference between the deep Atlantic and Pacific (δa − δp) are used in combination with model simulations to analyze the history of the

The Southern Ocean biogeochemical divide

It is demonstrated that atmospheric CO2 and global biological export production are controlled by different regions of the Southern Ocean, whereas global export production is controlled mainly by the biological pump and circulation in the Subantarctic intermediate and mode water formation region.

The ocean's response to a CO2-induced warming

The climate response to a large increase in atmospheric CO2 was investigated in a numerical experiment with a coupled ocean-atmosphere model. The study is focused on one aspect of the experiment, the

Varied contribution of the Southern Ocean to deglacial atmospheric CO2 rise

Glacial–interglacial changes in atmospheric CO2 are generally attributed to changes in seawater carbon chemistry in response to large-scale shifts in the ocean’s biogeochemistry and general

Changes in Atmospheric CO2: Factors Regulating the Glacial to Interglacial Transition

Observations of pCO2 and delta-C-13 for the deep sea, and delta-C-13 for shallow waters, furnish important constraints on the chemistry of the glacial ocean. The concentration of preformed nutrients



Uptake of excess CO2 by an outcrop-diffusion model of the ocean

A carbon cycle model is presented in which direct ventilation of intermediate and deep ocean waters in high latitudes is taken into account. The 1½-dimensional ocean model is an extension of a

A Tritium Box Model of the North Atlantic Thermocline

Abstract A box model of 1972 tritium observations on isopycnal surface in the main thermocline of the North Atlantic subtropical gyre is used to estimate the time scales and volume of exchange of the

Tracers in the Sea

A book about chemical processes occurring in the ocean with emphasis on the cycles of carbon and other nutrients. In addition to a treatment of the present distribution of those constituents,

Sensitivity of a global climate model to an increase of CO2 concentration in the atmosphere

This study investigates the response of a global model of the climate to the quadrupling of the CO2 concentration in the atmosphere. The model consists of (1) a general circulation model of the

Ice core sample measurements give atmospheric CO2 content during the past 40,000 yr

Recent measurements1,2 on ice samples from Camp Century (Greenland, 77°10'N, 61°08'W), Byrd Station (Antarctica, 80°01'S, 110°31'W) and Dome C (74°40'S, 125°10'E) suggest that during the late part of

A project to objectively analyze historical ocean temperature, salinity, oxygen, and percent oxygen saturation data for the world ocean has recently been completed at the National Oceanic and

Deep Circulation of the North Atlantic over the Last 200,000 Years: Geochemical Evidence

Data from a North Atlantic sediment core show that over the past 200,000 years there has been a continuous supply of nutrient-depleted waters into the deep North Atlantic, and indicates that the continental carbon inventory may have been less variable than previously suggested.
