Greenland Ice Sheet Project 2 (GISP-2) was completed the year after GRIP, at a site 30 km (19 miles) west of the GRIP site.
Notes on verification
Confirmed by multiple independent sources (University of Maine GISP2 project documentation and icecube.wisc.edu) regarding both the one-year completion gap and the west-of-GRIP location; minor variance in exact distance figures across sources.
