The McMurdo Dry Valleys of Antarctica are home to unique soil microbial communities. Using a specially designed Forced Diffusion flux chamber, we logged the first year-round record of soil surface CO2 flux in Hidden Valley. We observed low but positive fluxes during two sustained events, and conclud...
