Congrats to Martin Kurek who recently published his undergraduate research project in Chemical Geology. We developed a method to use a reducing agent (DTT) to extract elemental sulfur. Nice job Martin! You can download a full copy of the article from the following link for free until April 13, 2018. Kurek et al., Chemical Geology, 481:18-26, 2018.
New sulfide-films method published!
Check out our films method that was published in Marine Chemistry.
We demonstrate that photographic film can capture the spatial concentrations and stable isotope compositions of dissolved sulfide from water columns and pore waters. These films can be used in a wide variety of environments such as our study of the highly dynamic production and oxidation of hydrogen sulfide in the mud of the seagrass meadow shown below.

Midwest Geobiology Symposium at IUPUI
MWGB 2017 was a lot of fun. We had an excellent collection of talks and posters from several schools throughout the Midwest. Generous support from the Agouron Institute, School of Science, and the Department of Earth Sciences made this event possible. Special thanks goes to Lisa Pratt from IU Bloomington for her keynote address about the future of space exploration.
Class field trip to study the Ordovician.
We took students on a tour of Ordovician rocks in Indiana and Ohio as part of my course in the Evolution of Earth and Life (G335). The field trip combined students from IUPUI, IPFW, and the University of Cincinnati.
Solar Eclipse
Here I am demonstrating some hi-tech equipment for viewing the Great American Eclipse. The School of Science’s Eclipse Viewing Party was a lot of fun.

Bremen
I just got back from a great trip to the Thermo factory in Bremen, Germany.
Pub: New paleoclimate paper!
Congrats to the MURI Team
Over the past eight weeks MURI interns Amanda Evans, Amandeep Kaur, Omer Sajid, and Shruthi Garugu did research on a freeze core collected from a euxinic lake in Washington. They did an amazing amount of work, combining genetic with geochemical analyses to better characterize ecological changes that have occurred within the lake over the last 1400 years.
Today they presented their findings at the 2017 CRL Student Summer Poster Symposium. They did a fantastic job and my colleague Christine Picard and I are proud of all they accomplished. Thanks also goes to Alice Bosco and Charity Owings for mentoring and helping the students with their work in the lab.
Nice job team!
Congrats to Ashley Ring, ACS Seed intern
High School student Ashley Ring did an amazing amount of work during her American Chemical Society Project Seed internship. Today, she presented her poster showcasing her analyses of Archean rocks with her mentor Alice Bosco Santos. Ashely will be a freshman at Purdue University in a few weeks. Good luck Ashley and please come visit the lab whenever you can!
Return to Mahoney Lake
Our trip was a huge success in the Pacific Northwest, mainly because we had so many fantastic people helping us out.
It was great to see again our Canadian friends Nancy and Stu at the Centennial RV Park in Oliver, British Columbia. We couldn’t have accomplished anything without the amazing support of Wendy Pope from the BC Parks. Thanks also to Mark Abbott’s coring team Areile, Sofie, Sam, and MG from the University of Pittsburgh for collecting the Mahoney Lake surface cores.
I always love coming up here for research. I’m looking forward to returning again soon.
