1. Higher CO2 boosts phytoplankton in Antarctic waters

Oceanographers and climatologists are intensely studying how the ocean acts as a source or a sink of carbon dioxide (CO2). Under normal conditions, highly productive areas of the ocean are carbon sinks: Biological activity traps atmospheric CO2 within organic particles that fall to the ocean floor when organisms die. The efficiency of this biological C pump is known to depend on the productivity and species composition of phytoplankton, yet almost no information is currently available on how CO2 concentrations may affect these parameters. The results of Tortell et al. show that elevated CO2 concentrations increase phytoplankton productivity in the Ross Sea, Antarctica, and promote the growth of larger diatom chains. These chains are prolific bloom formers with very high capacities to export organic carbon to sediments. The authors expect that as ocean CO2 levels rise, similar blooms may be found in regions subject to natural ion fertilization, through upwelling of deep waters, windblown input, island effects, or melting sea ice.
