  • The Southern Ocean is a major carbon sink, but knowledge of its variability is limited, especially in the coastal Antarctic. Now, results based on 25 years of observations in the West Antarctic Peninsula show that the carbon sink is increasing rapidly, driven by summertime biological production linked to sea ice dynamics.

  • Oceanic uptake of carbon dioxide reduces the rate at which anthropogenic carbon accumulates in the atmosphere. Trends in oceanic and atmospheric carbon dioxide concentrations converge on a multidecadal timescale, according to an analysis of North Atlantic surface waters.

  • Efforts to control climate change require the stabilization of atmospheric carbon dioxide concentrations. An assessment of the trends in sources and sinks of atmospheric carbon dioxide suggests that the sinks are not keeping up with the increase in carbon dioxide emissions, but uncertainties are still large.

  • A study of a phytoplankton bloom in the Southern Ocean induced by the supply of iron from deep waters below finds that the efficiency of fertilization (the ratio of carbon exported to the ocean interior to the amount of iron supplied) is at least ten times higher than estimates from short-term experiments. This suggests that changes in the supply of iron from deep water to the surface ocean may have a greater effect on atmospheric carbon dioxide concentrations than previously thought.
