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:
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"
More information on Steig's research is available at the lab web pages and the research
group web pages listed above. Check the "Dissertations"
page to find out about our former students, and what they are doing
now at NCAR, NASA, and unversities around the world.
