GISP2
The Greenland Ice Sheet Project II, initiated by the Arctic System Science (ARCSS) at the National Snow and Ice Data Center (NSIDC), has retrieved a deep-ice core from central Greenland. The 3053.44-meter-deep GISP2 core is yielding a high-resolution, 110,000-year-plus history of global change, including at least the last interglacial and glacial cycle. This constitutes the longest such record available from the Northern Hemisphere. Properties being studied in the GISP2 core include gases and their stable isotopes, stable isotopes in ice, particles, major and trace element chemistry of ice, conductivity, and physical properties. The detailed view of global system history revealed from these ice-core properties will expand significantly our understanding of global change - evolution, process, trend, and coherence. The ARCSS and GISP2 is funded by the National Science Foundation (NSF).
