Greenland ice core project Greenland ice core project The Greenland Ice Core Project (GRIP) was a multinational European research project, organized through the European Science Foundation. Funding came from 8 nations (Belgium, Denmark, France, Germany, Iceland, Italy, Switzerland, and United Kingdom), and from the European Union. The project ran from 1989 to 1995, with drilling seasons from 1990 to 1992. GRIP successfully drilled a 3029-metre ice core to the bed of the Greenland ice sheet at Summit, Central Greenland from 1989 to 1992 at . Studies of isotopes and various atmospheric constituents in the core have revealed a detailed record of climatic variations reaching
