Melinda just returned from a coring expedition to Cara Blanca, Belize. We are collaborating with UIUC Anthropology Professor Lisa Lucero to investigate past landscape and climate variability in the region.
See this UIUC news release for more information!
Two grants have just been funded by NSF to support our work on tropical Pacific climate variability.
“Collaborative Research: P2C2–The Role of El Niño/Southern Oscillation (ENSO) Nonlinearities and Asymmetries in Modulating Tropical Pacific Climate” in collaboration with Drs. Christina Karamperidou and Fei-Fei Jin at University of Hawaii ($133K to Conroy)
“A Terrestrial Perspective of Last Millennium Hydroclimate Variability in the Central Tropical Pacific” ($367.5K to Conroy)
Thank you NSF!
It’s been a productive and busy April here in the Conroy lab. Nick, Andy, and Alie presented their Master’s research to the department as well as at the North-Central regional GSA meeting. Melinda also kept busy, chairing the paleolimnology session at GSA, which drew a nice crowd. I also had a nice visit to the Department of Earth Sciences at IUPUI, where I presented my recent water isotope research.
This labor of love–“Paired stable isotopologues in precipitation and vapor: A case study of the amount effect within western tropical Pacific storms“–was just published!

Three cheers for Melinda, who passed her preliminary exam on Tuesday!
Dr. Conroy will be speaking in the Department of Earth and Planetary Sciences at Northwestern University on Friday, January 29th, 2016. Her talk is titled: “Climate signals in stable water isotopologues across the tropical Pacific.“
Come see what we’ve been up to!
