Closure of the meridional overturning circulation through Southern Ocean upwelling
J Marshall, K Speer - Nature geoscience, 2012 - nature.com
The meridional overturning circulation of the ocean plays a central role in climate and
climate variability by storing and transporting heat, fresh water and carbon around the globe …

Ventilation of the Southern Ocean pycnocline
Ocean ventilation is the transfer of tracers and young water from the surface down into the
ocean interior. The tracers that can be transported to depth include anthropogenic heat and …

Localized subduction of anthropogenic carbon dioxide in the Southern Hemisphere oceans
The oceans slow the rate of climate change by absorbing about 25% of anthropogenic
carbon dioxide emissions annually. The Southern Ocean makes a substantial contribution to …

Toward a mechanistic understanding of the decadal trends in the Southern Ocean carbon sink
We investigate the multidecadal and decadal trends in the flux of CO2 between the
atmosphere and the Southern Ocean using output from hindcast simulations of an ocean …

Decoupling of iron and phosphate in the global ocean
We formulate a mechanistic model of the coupled oceanic iron and phosphorus cycles. The
iron parameterization includes scavenging onto sinking particles, complexation with an …

Glacial–interglacial changes in bottom-water oxygen content on the Portuguese margin
During the last and penultimate glacial maxima, atmospheric CO2 concentrations were
lower than present, possibly in part because of increased storage of respired carbon in the …

Anthropogenic carbon dioxide transport in the Southern Ocean driven by Ekman flow
Abstract The Southern Ocean, with its large surface area and vigorous overturning
circulation, is potentially a substantial sink of anthropogenic CO2 (refs). Despite its …

Changing controls on oceanic radiocarbon: New insights on shallow‐to‐deep ocean exchange and anthropogenic CO2 uptake
The injection of radiocarbon (14C) into the atmosphere by nuclear weapons testing in the
1950s and 1960s has provided a powerful tracer to investigate ocean physical and chemical …

Spatial and seasonal variability of the air‐sea equilibration timescale of carbon dioxide
The exchange of carbon dioxide between the ocean and the atmosphere tends to bring
waters within the mixed layer toward equilibrium by reducing the partial pressure gradient …

Interactions of the iron and phosphorus cycles: A three‐dimensional model study
We use an ocean circulation, biogeochemistry, and ecosystem model to explore the
interactions between ocean circulation, macro‐and micro‐nutrient supply to the euphotic …
