South Pole

General Information

South Pole Ice Core (SPICE; SPC14)

On January 23, 2016, the South Pole Ice Core (SPICEcore) project reached its final depth of 1751 meters (5745 feet; 1.1 miles), extending more than 54,000 years into the past. The 9.8 cm diameter ice core was drilled during the 2014/15 field season (0 to 736 meters) and 2015/16 field season (736 to 1751 meters) using the U.S. Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core that extends into the last glacial period and is the first record longer than 3000 years collected south of 82° latitude.

2004 Cores

During the 2004/05 austral summer, six cores were drilled at a site 4.7 km west of the Amundsen‐Scott South Pole Station for Jihong Cole-Dai. Four of the cores were ~40 m long firn cores, one core was 182 m in depth (SP04-C5), and one core was 102 m in depth (SP04C6). None of the cores have a continuous archive remaining, and all six of the cores are on the de-accession list.

SPRESSO

The SPRESSO (South Pole Remote Earth Science and Seismological Observatory) core (ICF core ID: SPRESSO02) was drilled by ICDS during the 2002/03 Antarctic field season at 89.93°S, 144.39°W to a depth of 291.26 meters. The core was sampled by the United States International Trans Antarctic Scientific Expedition (ITASE) team and subsequently archived at the NSF-ICF. The core has subsequently been heavily sampled, but there still is a continuous (albeit small) archive remaining. No drilling fluid was used during the drilling of the core.

2001 Cores

During the 2000/01 austral summer, two ice cores (SP01-1 and SP01-2) were drilled to a depth of ~123 m at the Amundsen-Scott South Pole Station for Michael Bender.
