Greenland Summit 14C and close-off studies
This data set, when complete, will contain the following: 1) 14CO, 14CO2 and 14CH4 data from measurements in firn air, firn matrix and shallow ice (to 130 m) at Greenland Summit. 2) Supporting firn air trace gas measurements for firn model tuning 3) Noble gas isotope measurements in firn air 4) high...
