Project Collaborators

Dr. Jon Chorover
Jon Chorover is an environmental chemist whose lab will help with organic matter analysis of drip water and mineral samples using fourier transform infrared spectroscopy (FTIR) and high performance size exclusion chromatography (HPSEC). Further, he will provide help in identifying mineral composition in samples from speleothems and rock walls that contain complex mineral assemblages using X-ray diffraction to elucidate crystalline phases, and FTIR to study the poorly crystalline materials.

Andrea Byrne Undergraduate Student 

Research Project:  Kartchner Caverns; Construction of a 16S rRNA clone library from a Kartchner speleothem.

Personal Background: Currently a junior pursuing a double major in Environmental Science and Chemical Engineering at the University of Arizona.  Andrea said about her first trip to Kartchner, “"It was quite an eye-opening experience. I have been to Kartchner Caverns before, but only as a tourist, not a scientist. I loved being able to go just slightly off the path and see things most people would never get to see about the cave. It is one thing to be given the prepared samples of the microbes already, and an entirely different thing to go out to the cave, and collect your own samples. There is so much more to experience. I was there to assist Marian with her samples, but the feeling of performing an experiment from start to finish, coupled with large quantities of cave mud all over my jeans?  Priceless!"

Matt Creamer
High School Student

Research Project: Kartchner Caverns; The effect of media and substrate on culturability of oligotrophic cave bacteria.
