Greenland Ice Core Project
The Greenland Ice Core Project (abbreviated: GRIP ) was a multinational European project to research the Greenland ice core . Between 1989 and 1992, the ice sheet in Central Greenland was drilled 73 ° N , 38 ° W to a depth of 3029 meters, where rocky ground was encountered. The oldest parts of the ice core come from a depth at which the ice has reached an age of more than 200,000 years. The drill core can provide information about the ecology and climate history of the last 100,000 years, that is the area in which the core is undisturbed and clearly datable.
The project was organized by the European Science Foundation , with funding from Belgium , Denmark , Germany , France , Iceland , Italy , Switzerland , the United Kingdom and the European Union .
The ground-level disturbances motivated the implementation of the North Greenland Ice Core Project ( NGRIP , 1999 to 2003). It was able to extract a 3,085 m long ice core ( 75 ° N , 43 ° W ) in a region in northern Greenland with a flat bottom . The ice in this core reaches back 123,000 years undisturbed to the Eem warm period .
