Microbes near the surface of the Southern Ocean sustain the polar food chain — impacting the nutrient flow from the surface to the depths where other microbial communities thrive in the dark. #NatGeoExplorer Allison Fong sampled sea ice in the Weddell Sea to understand how changes in the sea ice may affect the microorganisms that feed the Southern Ocean's wildlife populations. This research better informs our understanding of how microbe communities absorb carbon dioxide from the atmosphere and
