Dye 3

Dye 3 is an ice core site and previously part of the Distant Early Warning (DEW) line, located at (65°11′N 43°49′W / 65.183°N 43.817°W, 2480 masl) in Greenland. As a DEW line base, it was disbanded in years 1990/1991. An ice core is a core sample from the accumulation of snow and ice that has re-crystallized and trapped air bubbles over many years. The composition of these ice cores, especially the presence of hydrogen and oxygen isotopes, provides a picture of the climate at the time. Ice cores contain an abundance of climate information.
