A unique interdisciplinary research team heads this project with specific expertise in geology, microbiology, and physics. Project milestones include:
- Performing in situ crystallization experiments to determine the form and chemistry of travertine deposited when the microbes have been UV-irradiated, a sterilization technique that will leave the other fundamental physical and chemical conditions of the spring drainage outflow relatively unchanged.
- Documenting associations between calcite crystal growth form, distribution and chemistry with microbial form, diversity and metabolic activity.
- Quantitative modeling of carbonate terrace formation using stochastic differential equations to describe the combined effects of geological and biological processes.
