| Summary: | This dataset includes sample information and metadata for radiocarbon ages of organic remains collected in northwest Greenland during summers 2012 and 2014. There are 60 ages of subfossil plant remains that have been recently exposed at the margins of the Greenland Ice Sheet and North Ice Cap. 6 ages are of subfossil plant remains transported along shear planes in the Greenland Ice Sheet margin near Thule Air Base. 2 ages are of subfossil plant remains transported along shear planes in the Greenland Ice Sheet margin in Nuntarssuaq. 24 ages are of subfossil plant remains in situ, recently exposed by the receding Greenland Ice Sheet margin in Nunatarssuaq. 7 ages are of subfossil plant remains transported along shear planes in the North Ice Cap margin in Nuntarssuaq. 16 ages are of subfossil plant remains in situ, recently exposed by the receding North Ice Cap margin in Nunatarssuaq. 1 age is of subfossil plant remains in situ, recently exposed by the receding the Tunnel Glacier margin in Nunatarssuaq. 4 ages are of plant remains in sediment cores from BEMEWS lake, near Thule Air Base. Data reported are direct radiocarbon measurements made at the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility. Columns 16 and 17 contain sample latitudes and longitudes, and samples 18 and 19 contain general sample locations and whether samples occurred in situ or not. |
