The big unknown: Factoring marine sediments into climate calculations
Date:12/4/2013

The discussion over the best ways to reduce greenhouse gas emissions and remove existing carbon dioxide from the atmosphere often includes measures that entail planting trees. But this discussion overlooks an important factor: trees are not the only plants that take up carbon dioxide. In fact, microscopic marine phytoplankton already play a critical role in regulating today's carbon cycles.

These tiny organisms consume carbon dioxide from the atmosphere and move it to marine sediments in the deep ocean in a process called "the biological pump". Currently, more than 99 per cent of the Earth's carbon is bound up in these sediments, locked away in the depths of the ocean.

A new EU-funded project called "OCEAN-CERTAIN" has been created to improve our understanding of the biological pump, so that its significance in shaping future climate change is clearer. The project will be led by researchers from the Norwegian University of Science and Technology (NTNU) in Trondheim, and will examine and compare the situations in different ocean areas on the planet.

"The marine ecosystem, from microorganisms up to fish, mitigates the accumulation of CO2 in the atmosphere through its activity, but there are major uncertainties about the importance of these processes and how they are affected by human activities," says Yngvar Olsen, a professor in NTNU's Department of Biology, and the project's coordinator. "We are a broad group of scientists from Europe, Chile and Australia, which is important in seeing the challenge from a global perspective. We are both natural scientists who will work with the ecosystem and the biological pump and social scientists who will study possible consequences for society, or people in general."

The biological pump as a process is well known to marine scientists, but there remains great uncertainty about how much carbon is bound up in ocean sediments annually, and how the process will be affected by changing clim
