Look for Shelley's paper on the first measurements of the seasonal cycle of Δ17O of nitrate in Greenland snow in an upcoming issue of Journal of Geophysical Research PDF. Look for our paper on the imprint of El Niño in Antarctica in the August 2008 Proceedings of the National Academy of Sciences. NCAR Press Release, here. Congratulations to Julia Jarvis, who passed her PHD exam on August 14th, 2008. Look for Julia's paper on modeling of nitrogen and oxygen isotopes in atmosphere and snow nitrate (Geophysical Research Letters (abstract)) Congratulations to Lora Koenig, who passed her PHD exam on June 13th, 2008, and has just accepted a job with NASA's Cryospheric Sciences Branch. |

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 temperature and snow
accumulation variability in Antarctica, through ice core measurements,
satellite remote-sensing; development and application of methods to
measure the nitrogen and oxygen isotope concentrations in atmospheric
"odd-N" species (HNO3, NO2, NO); and acquisition of
ice cores from alpine regions. 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 solicted
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.
