Review of survey activities 2013 (Preface)

2013 was a very special year for the Geological Survey of Denmark and Greenland (GEUS), which acquired its pre-sent name in 1995 when the Geological Survey of Denmark, established in 1888, and the younger Geological Survey of Greenland were merged. On 4 April 2013 GEUS celebrated its 125th anniversary with a series of presentations by promi-nent guests and GEUS scientists followed by a reception and a gala evening. GEUS’ 125-year long history has provided an overwhelming body of results and experience, and today GEUS is broader, stronger and more international and col-laborative than ever, covering all aspects of which a geologi-cal survey can be of use for society.
