News

We have submitted a paper based on our work on Mt. Waddington, British Columbia, showing that the ice core record there contains clearly-defined annual layers, allowing a ~40-year climate record to be obtained, which compares favorably with instrumental data. Peter Neff is the lead author of the Journal of Glaciology manuscript. Future work to retrieve a core to bedrock should yeild a record several hundred years in length.

Post-doc Qinghua Ding's paper on the influence of the tropics on the Southern Annular Mode (SAM) -- showing that the SAM index in the Pacific sector of Antarctica primarily reflects tropical-forcing -- is now in press in the Journal of Climate (preprint available here). Together, with our publications in Nature and Nature Geoscience in the last couple of years, and a new paper to be submitted to Science, these results suggest that what happens in the tropical Pacific (which is highly uncertain) has significant consequences for what happens to the Antarctic ice sheet and the surrounding sea ice.

Background & Current Research:
Eric Steig completed his PhD in Geological Sciences at UW in 1995, was Research Assistant Professor at the University of Colorado from 1996-1998 and Assistant Professor at the University of Pennsylvania before returning to UW in 2001. He was promoted to Full Professor in 2008. He is the founding co-director of ISOLAB, a state-of-the art isotope geochemistry facility involving research ranging from climate and atmospheric chemistry to geobiology.

Steig teaches environmental earth science, isotope geochemistry and paleoclimatology at both the graduate and undergraduate levels. With his graduate students, postdocs, and lab staff, he uses various methods to develop time series of past environmental changes as a context for understanding contemporary and possible future change. Current focus areas include recent temperature and snow accumulation variability in Antarctica; development and application of methods to measure nitrogen isotope concentrations in atmospheric "odd-N" species (HNO3, NO2, NO), and the Δ17O oxygen isotope anomaly in both odd-N and water; and acquisition of ice cores from both Antarctica and temperate alpine regions. He is also collaborating with paleontologist Peter Ward on research at the K-T and other 'mass extinction' boundaries in the geologic record. Research support is from the National Science Foundation's Polar and Atmospheric Sciences Programs, and from the Canadian Foundation for Climate and Atmospheric Sciences (CFCAS).

He has been a contributor to science planning for glaciological and solid-earth geosciences in the polar regions, to international efforts to track pollution in the Arctic, and to archive and sample allocation at the National Ice Core Laboratory. He is a current member of the NSF-funded Ice Core Working Group and the steering committee for the International Partnerships in Ice Coring Sciences (IPICS) initiative. Steig served as Associate Editor (2001-2004) and Senior Editor (2005-2008) of the journal Quaternary Research, and continues as Special Editor for occasional solicited papers of interest. Steig is active in public education, and has given lectures to organizations such as the Padilla Bay National Estuarine Research Reserve on the Washington State coast, and the Nature Conservancy. He is a founding member and contributor to the influential climate science web site, "RealClimate.org"
