The Greenland Analogue Project – GAP – is a multilateral research project on Greenland's west coast (east of Kangerlussuaq). The aim is to improve the current understanding of how an ice sheet affects the groundwater flow and water chemistry around a deep geological repository in crystalline bedrock during glacial periods and with the presence of permafrost. Researchers from universities and geological surveys in the United Kingdom, the United States, Canada, Denmark, Finland and Sweden are studying the ice sheet and are drilling through the ice and in the bedrock at the ice edge.
