Visual stratigraphy of the EastGRIP ice core (14 m - 2021 m depth, drilling period 2017-2019) ...
A continuous high-resolution record of digital images in dark field illumination mode were taken from the East Greenland Ice Core Project (EastGRIP or EGRIP) ice core (Latitude: 75.630000 Longitude: -35.980000) in the depth interval from 14 m to 2121 m of depth. Stratigraphic layering in the monomin...
