 The record of past climates of the earth are faithfully recorded in the great ice sheets of Antarctica and Greenland and the recovery of ice cores from these vast storehouses of climate information is one of the most exciting and scientifically rewarding pursuits for glaciologists today. How are these cores retrieved and brought back to the laboratory for analysis? How is climate information extracted from ice cores? What have we learned about the Earth’s past climate that helps to inform present and future climate?

 

Dr. Joan Fitzpatrick is an ice researcher and founding Technical Director of the US National Ice Core Laboratory research scientist at the Geosciences and Environmental Change Science Center at the US Geological Survey in Denver, Colorado.  She has been an active researcher in the field of glaciology and ice core analysis since 1989 and has participated in every US-sponsored deep ice-drilling project since that time.  Her current work is focused on the recently-completed ice core from the West Antarctic Ice Sheet (WAIS) Divide site– a location that promises to provide a uniquely well-resolved 60,000-year climate record for West Antarctica.
