Central role of Southern Hemisphere winds and eddies in modulating the oceanic uptake of anthropogenic carbon
[1] Although the world ocean is known to be a major sink of anthropogenic carbon dioxide, the exact processes governing the magnitude and regional distribution of carbon uptake remain poorly understood. Here we show that Southern Hemisphere winds, by altering the Ekman volume transport out of the Southern Ocean, strongly control the regional distribution of anthropogenic uptake in an ocean gene...
متن کاملAntarctic lakes suggest millennial reorganizations of Southern Hemisphere atmospheric and oceanic circulation.
The phasing of millennial-scale oscillations in Antarctica relative to those elsewhere in the world is important for discriminating among models for abrupt climate change, particularly those involving the Southern Ocean. However, records of millennial-scale variability from Antarctica dating to the last glacial maximum are rare and rely heavily on data from widely spaced ice cores, some of whic...

متن کاملAtmospheric aerosols alter oceanic activity
Atmospheric aerosols alter oceanic activity Oceans remain a key convergence point where anthropogenic and natural environmental effects can affect climate change and alter food chains. For example, mineral dust, soot, organic molecules, and other microscopic particles can become aerosolized in the atmosphere and provide nutrients and trace metals for phytoplankton in the open ocean.

متن کاملThe oceanic sink for anthropogenic CO2.
Using inorganic carbon measurements from an international survey effort in the 1990s and a tracer-based separation technique, we estimate a global oceanic anthropogenic carbon dioxide (CO2) sink for the period from 1800 to 1994 of 118 +/- 19 petagrams of carbon. The oceanic sink accounts for approximately 48% of the total fossil-fuel and cement-manufacturing emissions, implying that the terrest...
