East Greenland Ice-core Project (EastGRIP) is an international science station and drilling camp on the Greenlandic ice sheet (76N 36W), led by the University of Copenhagen, with the logistics coordinated by the Danish Centre for Ice and Climate. The Northeast Greenland Ice Stream (NEGIS) is the largest ice stream in Greenland. It begins at the central ice divide and cuts straight through the ice sheet in a wedge shape to feed into the ocean through three large ice streams (Nioghalvfjerds isstrømmen, Zachariae isbræ and Storstrømmen). The EastGRIP location is near the beginning of this ice stream.
The team at EastGRIP aims to drill through 2650 meters of ice dating back 120,000 years to glean new knowledge of ice-sheet dynamics and how fast-flowing ice streams will contribute to sea-level rise. The resulting ice core will also create a new record of past climatic and atmospheric conditions from the northeastern part of the Greenland Ice Sheet, informing our understanding of how it may respond to a changing climate.
This summer marked the first fieldwork season since 2019 after the COVID-19 pandemic caused the cancellation of the 2020 and 2021 field seasons. After two months of preparation this spring, the drilling operation started on July 7th and ended on August 6th, yielding a new 300-meter core at a maximum depth of 2418.23 meters. That puts them under 250 meters from their target depth, which the team aims to achieve next year.
The EastGRIP camp's facilities, especially its ski way, also attract other scientific research, which uses the camp as an airport or logistics hub for other projects.

The length of the ice core is then measured. Finally, the sum of all these measured core lengths gives the total length of the ice core.
