60-second Science

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.
