The North Greenland Eemian Ice Drilling (NEEM) is an international ice core research project aimed at retrieving an ice core from North-West Greenland (77.45°N 51.06°W) with the goal of reconstructing climate back through the previous interglacial period. An undisturbed climate sequence spanning the Eemian interglacial in Greenland ice has eluded the community for more than three decades and the search continues. At NEEM, four field seasons of drilling have yielded an ice core that has reached bedrock at 2537.36 meters, with the deepest few meters of ice core containing a banded mixture of ice and rock. The ice from NEEM spans the entire Eemian interglacial and beyond into the previous glacial period, however, once again the stratigraphic integrity of the oldest parts of the record is disturbed. Efforts are underway to determine if the Eemian record can be unscrambled. I will describe the story of our search for the Eemian in Greenland, what we can learn from the NEEM ice core, and where we could go from here.
