I lived in Alaska for seven years growing up and worked in the Antarctic off and on for the better part of a decade, so I’m well acquainted with permafrost or permanently frozen soil. Mostly I remember that it makes digging really difficult.
But just like ice cores, it can hold all kinds of information about climate change. Here’s a great article about Emily Wilson who’s a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. She has developed a new instrument to measure the greenhouse gases that leak out of melting permafrost, and she and her team will be taking new and exciting measurements near Fairbanks, Alaska, in June.
