D5 | NSF Ice Core Facility

General Information

D5 is a 10.2 cm diameter, 148 m long core drilled in 2003 to investigate annual accumulation over recent centuries in central Greenland. The ice core was analyzed by CFA by Joe McConnell and annually dated based on multiple seasonal markers, including hydrogen peroxide (H2O2), total sulfur, lead, and sea-salt and dust tracers (for example, Na, Mg, Ca). The period of record in the D5 core is 1765-2003 (McConnell and others, 2019). There is only a small section of core remaining in the archive.
