Brook Ice Core Data
This ice core data is archived at the World Data Center for Paleoclimatology and is available through the Ice Core Data Gateway. The data includes methane data from the Greenland Ice Sheet Project 2 (GISP2) and Taylor Dome, and interplanetary dust helium isotope data from GISP2 and Vostok cores.
Data Collection Sites
GISP2 is an ice core project that drilled through the Greenland ice sheet and 1.55 meters into bedrock. The ice core is 3053.44 meters in depth, the deepest ice core recovered in the world at the time. The ice core was completed in 1993 after five years of drilling.
Taylor Dome is an ice-accumulation area on the East Antarctic ice sheet. The dome is a ridge about 20 x 80 km, which lies inland of the Transantarctic Mountains. Deep drilling by the Polar Ice Coring Office (PICO) at Taylor Dome reached bedrock at a depth of 554 meters during the 1993-1994 austral summer season.
The Russian Vostok Station in East Antarctica was the site of a collaborative ice-drilling project between Russia,
the United States, and France. In 1998, the site yielded the deepest ice core ever recovered, reaching a depth of 3,623 m.
