As a glaciologist specializing in polar ice sheets, I've been visiting the Antarctic and Arctic since 1995. This blog chronicles my experiences in the field. Feel free to ask questions, and I'll respond as soon as I can. Current research is based upon work supported by the NSF and NASA. Any opinions, findings and conclusions or recomendations expressed in this material are my own and do not necessarily reflect the views of the funding agencies (NSF and NASA).
