My colleagues and I have two new papers out this month. The first, published in Journal of Geoscience Education, describes our approach for incorporating scientific argumentation into a global change course to improve student writing and learning. The second, in Journal of Geophysical Research - Atmospheres, provides evidence of rapid transport of ash and sulfate from the June 2011 eruption of Puyehue-Cordón Caulle (Chile) to West Antarctica. This latter paper developed from Eleanor Dowd's First-Year Women in Science project at Dartmouth. Congratulations on your first paper, Eleanor!

I just accepted an offer to join the Colby College Geology Department as an Assistant Professor. I'll be starting there in the fall, teaching topics related to paleoclimate and geochemistry. I'm thrilled to be joining a school that cares so deeply about undergraduate education, and I look forward to this next phase of my career!

A special issue of Paleoceanography features research from the WAIS Divide ice core project, including some of my PhD work on past volcanic eruptions. The issue includes articles published in AGU journals through May 2016. What an amazing experience and privilege it has been to be a part of this project!

I joined the Dartmouth Stretch (off-campus geology program) for two weeks in Banff National Park, Alberta, Canada. Led by Professor Bob Hawley, we studied the mass balance and 20th Century retreat history of the Athabasca Glacier. What a great crew!
Here we are at Lake Louise.

Just back from a successful field season in Alaska with Dartmouth undergraduate and graduate students. Looking forward to analyzing our new snow and sediment samples to evaluate dust provenance in central Alaska!
Here we are with all our gear, about to depart Denali Base Camp by ski plane.

The Lamont-Doherty Earth Observatory Summer Intern Program will soon be accepting applications. If you are an undergraduate interested in doing earth science research over the summer in a stimulating and supportive environment, please see this website for information on how to apply. My colleagues and I are looking for an intern to work on a project entitled, "How old is the dust? Can we use K-Ar to show where dust comes from in the Southern Hemisphere?" Check it out on the Lamont website, and contact me if you are interested and/or have any questions!

Our paper on the Southern Hemisphere westerlies was just published in Climate of the Past. In it, we use changes in the sizes of dust particles trapped in the WAIS Divide ice core to reconstruct past variability in the winds that blow around Antarctica. The article can be found here.

Check out this photo essay and short article, "Did New Zealand Dust Influence the Last Ice Age?" posted on Columbia's Earth Institute blog, State of the Planet.
The essay shows pictures from my recent field season and explains why I went to New Zealand to collect dust samples generated during the last ice age. Now I'm back in the lab, processing these new samples. Stay tuned for the results!

I'm excited to announce that my colleagues and I were just awarded a $10,000 grant from the Lamont Climate Center for a project entitled Assessing Northern Hemisphere westerly wind variability in the North Pacific during the past millennium!
