Dataset Title High-resolution record of North Greenland Ice Core Project (NGRIP)
Dataset Purpose This Water stable isotope record covers the Holocene, the entire last glacial period and part of the Eemian Period
Dataset Abstract NGRIP is a multinational research program, funded by participating institutions in Germany, Japan, Sweden, Switzerland, France, Belgium, Iceland and the US. Primary sponsor is the Danish Research Council.
Acquisition Methodology The drilling works began in the 1996 field season, and reached bedrock at a depth of 3090 m on July 25th, 2004. The initial isotope data series is based on 5 cm continuous sampling from surface to bottom of the core, or 61100 individual measurements. For more information on NGRIP, please see the Niels Bohr Institute Centre for Ice and Climate.
Quality The NGRIP core has been cross-dated to the GRIP core ss09sea chronology down to 105 kyr BP using the high-resolution ice isotope profiles and volcanic events from in the ECM and DEP records. Older ice is cross-dated to the Antarctic Vostok ice core records by using concentrations of methane and d18 of the entrapped air.

Description The NGRIP is a multinational research program, funded by participating institutions in Germany, Japan, Sweden, Switzerland, France, Belgium, Iceland and the US. Primary sponsor is the Danish Research Council. The Goal is to retrieve and analyze a 3080 m long ice core drilled through the Greenland ice sheet at a place selected to give the longest reliable record.

Instrument Description The NGRIP deep drill is based on an original JARE design used in Antarctica. The drill is optimized f or core quality and speed. The drill is 11 m long, and is hanging in a 7,2 mm cable. It is battery powered, and all functions are electronically controlled from the surface. During drilling, the upper part of drill is prevented from rotating by 3 leaf springs. The bottom part of the drill rotates, and removes a ring of ice, leaving the ice core in the center. The cuttings are pumped into the drill , and brought with the core to surface for each run. Core diameter is 98 mm, and core length 3,5 m.
