During spring 2014, we drilled an ice core on the northwestern Greenland Ice Sheet, recovering a core of total length 225m.　We also conducted stratigraphic observations, measurements of the density of the ice core, near-infrared photography of the ice core, preparation of liquid samples for chemical analysis, and measurements of borehole temperature.　The pore close-off depth was 60m, and the temperature in the borehole was −25.6°C at a depth of 10m.　In addition, we conducted snow-pit observations, ice-velocity and surface-elevation measurements using the global positioning system (GPS), meteorological observations, and installation of an automated weather station (AWS).
