Bob Tipping, Ph.D., Director, Minnesota Geological Survey
Seminar Lab Subject:
Current and Future Mapping at the Minnesota Geological Survey (MGS)
Seminar Lab Location :
In-person only at U of Minnesota, Keller Hall, Room 3-230
Lecture start time 7:00 PM CT.
Seminar Lab Details:
Summary: Rather than providing a detailed history of MGS, this talk focuses on current and future work as it relates to the collection and spatial interpretation of surface and subsurface data. Mapping tasks are called out specifically because they are fundamental to the MGS mission; maps and their associated databases provide the best understanding of what we know about the distribution of Minnesota’s rock and water resources. I would like to introduce you to current data collection and mapping methods at the Survey and speculate on how these methods might change in light of improved data collection, storage and analysis.

While at the Health Department, Bob was a hydrologist supervisor in the Source Water Protection Unit. Prior to that, he was a senior scientist at the Minnesota Geological Survey, and adjunct faculty member in the Department of Earth Sciences and the Water Resources Science program - both at the University of Minnesota. His research interests are in aquifer characterization, groundwater chemistry and groundwater-surface water interaction. Bob has a Ph.D. in Water Resources Science from the University of Minnesota, M.S. in Geology the University of Minnesota, and B.A. in History from Carleton College.
About the Minnesota Geological Survey: MGS is a unit of the Newton Horace Winchell School of Earth Sciences in the University of Minnesota. The Survey is the University outreach center for the science and technology of earth resources in Minnesota. The Survey conducts basic and applied earth science research, conveys that information to the public through publications and service activities, and promotes earth science education. Minnesota is its exclusive focus.

Summary, there is bridge work over the Mississippi on 94. If you can, you might want to come up I-35E instead of I-35W. If so, consider exiting at University Avenue to avoid the backups.
This changes almost daily, so check before you depart for the most current status.
Seminar Lab Details:
Summary: Stromatolites are layered structures built by the buildup of chemical sediment under the influence of microbial communities. Hundreds of stromatolite forms have been identified, most of them in Proterozoic-aged rocks. During the Proterozoic, observed morphologies include flat-laminated, domal, columnar, branching columnar and conical, across scales from a few centimeters to tens of meters. Furthermore, the middle Proterozoic era (~1300-1000 Ma) records the highest diversity of stromatolite forms, with fewer forms recognized in older and younger successions. Although it is well known that stromatolites result from the interaction of microbial communities, detrital sediment, and carbonate precipitation, the controls on stromatolite morphology are surprisingly less well-understood. This presentation explores how macroscopic stromatolite morphology can best be understood as lamina form expressed over time. Because stromatolite laminae represent an active growth surface at the time of formation, they therefore record the topography of the depositional surface, reflecting the interactions between the emergent stromatolite and its environment. This "lamina-upward" approach to morphological analysis provides a useful tool for explaining the complexity and diversity of stromatolite form through Earth history.
Biography: Julie Bartley is a Professor in the Department of Environment, Geography, and Earth Sciences at Gustavus Adolphus College, where she has been working since 2009. Prior to arriving at Gustavus, Julie was a faculty member at the University of West Georgia. She earned her Bachelor’s degree in Chemistry at Bryn Mawr College, her Master’s degree in Chemistry at UCLA, and her PhD in Geology at UCLA.
Most of Julie’s research seeks to recognize and interpret the interplay between life and environment on the early Earth. Her work ranges from the geochemical record preserved in carbonate rocks, to the ways microbes become fossilized, to the large-scale, reef-like structures built by microbial communities on ancient carbonate platforms. These projects have taken her to field areas in Siberia, Arctic Canada, West Africa, Argentina, and the Bahamas, as well as localities in the contiguous 48. This work has also connected her with the search for biosignatures on Mars, and she has worked with teams exploring the best strategies for rover-based science on other planets.
