Flow‐induced mixing in the GRIP basal ice deduced from the CO2 and CH4 records
This paper documents a larger degree of mixing in ice near the bottom of an ice sheet than described, or suspected, previously. It shows, thanks to favourable circumstances due to CO2 and CH4 production underneath the ice, that flow‐induced mixing within the basal ice has taken place at the scale of...
