Data from: Islands in the ice: detecting past vegetation on Greenlandic nunataks using historical records and sedimentary ancient DNA meta-barcoding
Nunataks are isolated bedrocks protruding through ice sheets. They vary in age, but represent island environments in “oceans” of ice through which organism dispersals and replacements can be studied over time. The J.A.D. Jensen’s Nunataks at the southern Greenland ice sheet are the most isolated nun...

Nunataks are isolated bedrocks protruding through ice sheets. They vary in age, but represent island environments in “oceans” of ice through which organism dispersals and replacements can be studied over time. The J.A.D.
