Researchers are investigating how an iron infusion from glacial meltwater might change Antarctica’s seas and the climate.

All aboard the Nathaniel B. Palmer, a research vessel making its
way through the waters of West Antarctica. Journalist Sofia
Moutinho is joining a team of chemists trying to find out how
glacial melting is changing ocean chemistry—and what those changes
might mean for the global climate. The researchers want to know
whether a negative feedback loop could take shape in Antarctica’s
seas. Carbon dioxide contributes to the rise in warming that is
melting the glaciers. As glacial melting releases iron,
phytoplankton feast. Phytoplankton in turn remove carbon from the
air, potentially causing a cooling effect. Stay tuned for next
Friday’s episode, where Moutinho will embark on a hunt for sea ice
and hear about the researchers’ special encounter with Adélie
penguins. E-mail us at sciencequickly@sciam.com if you have any
