Uncertainty about the causes of glacial-interglacial CO2 variations demonstrates our
incomplete grasp of fundamental processes that govern our climate and thus one of the …

The present thesis investigates the role of the oceans with respect to past and future
changes in global carbon cycling on time scales of hundreds to several thousand years. This …

A coupled climate-carbon cycle model and ice core CO2 data from the last glacial period are
used to explore the impact of changes in ocean circulation on atmospheric CO2 …

We use an Earth system model of intermediate complexity, CLIMBER‐2, to investigate what
recent improvements in the representation of the physics and biology of the glacial ocean …

The effect of idealized wind-driven circulation changes in the Southern Ocean on
atmospheric CO 2 and the ocean carbon inventory is investigated using a suite of coarse …

The increase in atmospheric CO2 mixing ratio at the close of the Pleistocene epoch was part
of a larger reorganization of the global carbon cycle that involved the regrowth of the …

We conduct a model–data analysis of the marine carbon cycle to understand and quantify
the drivers of atmospheric CO 2 concentration during the last glacial–interglacial cycle. We …

Climate change over the last several decades is suggested to cause a decrease in the
magnitude of the uptake of CO 2 by the Southern Ocean (Le Quere et al.). In this study, the …

The CO2 uptake by the Southern Ocean (< 35° S) varies substantially on all timescales and
is a major determinant of the variations of the global ocean carbon sink. Particularly strong …

Abstract The Southern Ocean plays a pivotal role in climate change by exchanging heat and
carbon, and provides the primary window for the global deep ocean to communicate with the …
