Anatomy of a Dansgaard-Oeschger warming transition: High-resolution analysis of the North Greenland Ice Core Project ice core
[1] Large and abrupt temperature oscillations during the last glacial period, known as Dansgaard-Oeschger (DO) events, are clearly observed in the Greenland ice core record. Here we present a new high-resolution chemical (2 mm) and stable isotope (20 mm) record from the North Greenland Ice Core Project (NGRIP) ice core at the onset of one of the most prominent DO events of the last glacial, DO-...
متن کاملIce core studies from Mt Kenya , Africa , and their relationship to other tropical ice core studies
Mt Kenya, located at the Earth's equator, is one of the few tropical mountain areas in the world where glaciers exist today. Two i ce cores to a depth o f 1 3.4 and 11.4 m were retrieved from the col (4870 m) between the Lewis and Gregory glaciers. Microparticle, oxygen isotope and total S radioactivity analyses were conducted. The results of these measurements, as well as those from other trop...

متن کاملIce-core evidence of abrupt climate changes.
Ice-core records show that climate changes in the past have been large, rapid, and synchronous over broad areas extending into low latitudes, with less variability over historical times. These ice-core records come from high mountain glaciers and the polar regions, including small ice caps and the large ice sheets of Greenland and Antarctica.
