Despite innovations in remote sensing technology, on-site geological field work remains essential to mineral and petroleum exploration. Hence, relevant introductions to the earth sciences should allow students to learn and apply basic field skills and mapping technology. Unfortunately, large lecture-style introductory courses do not lend themselves easily to individual-based field work. In addition, many earth science programs have access to only limited local outcrop exposures, often of rocks with little structural complexity. The exercise presented here was designed as an assignment for students in EOS 11: Dynamic Earth (>120 students). It was facilitated in groups of ten students at a time over the course of a week. Wooden data stations (~60) and rock samples stand in for exposures (”virtual outcrops”). Students used hand-held GPS units to map the station’s distributions across the Duke campus and their spatial orientation relative to one another. Each data station provides information on the rock type and orientation (strike and dip) of the local “virtual” strata. Using this information, students constructed a geological map and cross-section through the Duke campus. The exercise not only teaches applied mapping, GPS, and data collection skills, but also requires students to critically evaluate inference making, scientific uncertainty, and hypothesis testing.

With support from a CIT Strategic Initiative grant, this Spring students in the Undergraduate Certificate Capstone for the Information Science + Information Studies Program put together a multimedia mapping toolkit to be used by DukeEngage students, the WISER program, and Global Health researchers in Muhuru Bay, Kenya beginning in Summer 2009. Students researched and tested GPS-enabled cameras and trackers, developed map development templates for Google Earth layers, documented best practices for research activities and media capture projects, explored information visualization strategies to combine top-down data with bottom-up observations, created an infrastructure back end for content management, and built a prototype for the location-based, media rich mapping environment based on Duke campus and the surrounding community. DukeEngage students traveling to Kenya will use the toolkit this summer, and then continue their work with the content when they return, developing maps as research and discovery tools and creating new resources for the Muhuru Bay community. We plan to make this a multi-year project into which students from various backgrounds and with various skillsets can participate. The project itself is part of a larger ongoing mapping and hybrid world theme within the ISIS program and the broader interdisciplinary Visual Studies Initiative at Duke.
