In this Study Abroad course, our class travels to the Cancún, Mexico area to explore issues at the intersection of karst geology, tourism, and water management. We meet engineers at drinking water and wastewater plants in rapidly developing parts of Cancún, hike through an underground river cave system, snorkle in cenotes, windows into the karst aquifer, and learn about local water and tourism issues from community members, scientific divers, and ecologists. Course updates include enhanced qualitative and quantitative research carried out by students to investigate the course themes in consultation with local partners. Offered in Spring 2023, Maymester 2026. Co-led with Dr. Kelly Alley.
