Glacial Geology and Geochronology Research Group

Welcome to the Glacial Geology and Geochronology Research Group at the University of Maine!  Use the links below to learn more about our ongoing research.

Graduate Student Opportunities:

We have a Fall 2025 opening for a graduate student at the MS level. The student will conduct research on the characteristics and age of subglacial meltwater landforms in the Transantarctic Mountains of Antarctica as part of a project on the past thickness of the East Antarctic Ice Sheet. This project does not involve field work, but rather is based on remote sensing, satellite image interpretation, and GIS analysis. Experience in GIS analysis is key. Experience identifying and mapping landforms from imagery is a plus. This position is supported by a research assistantship and includes a tuition waiver. If interested, contact Dr. Brenda Hall (BrendaH@maine.edu).

Current Research

We are working on projects in western Maine/northern New Hampshire, Scotland, Greenland, Mongolia, New Zealand, South America, and Antarctica.

  • April, 2024: Dr. Aaron Putnam, graduate students Tricia Hall, Katie Westbrook, and Zander Roman returned from months of fieldwork in the Southern Alps of New Zealand where they collected samples from boulders for cosmogenic surface exposure age dating.
  • April, 2024: Dr. Brenda Hall, graduate students Sera Thomas, Meghan Spoth and Maraina Miles just returned from a second season in Tierra del Fuego, Chile, along with colleagues from the University of Cincinnati and the Universidad de Magallanes and a science journalism student from Northwestern University. They collected sediment cores from bogs and samples from boulders for cosmogenic exposure age dating.

  • Congratulations to PhD student Scott Braddock who received outstanding graduate student award and PhD student Peter Strand who received the outstanding graduate research award in the College of Natural Sciences, Forestry, and Agriculture.
  • Brenda Hall, graduate students Meghan Spoth and Maraina Miles and undergraduate Eva Griffiths spent a month on a sailboat in the Beagle Channel, southern Chile, along with colleagues from the University of Cincinnati and the Universidad de Magallanes and a science journalism student from Northwestern University. They were collecting data to help answer questions about the cause of the last ice-age termination. Stay tuned for a larger report on the field season soon!
  • Former student Tess Walther, along with Brenda Hall, George Denton, and Chris Hendy (University of Waikato, NZ) just had a paper accepted in Quaternary Science Advances concerning Antarctic glacial history. This paper stems from Tess’s MS degree. Congratulations Tess!
  • Current student PhD Meghan Spoth, along with Brenda Hall and colleagues at the University of Cincinnati and the South Atlantic Environmental Research Institute just had a paper accepted in Quaternary Science Reviews concerning shifts in the southern hemisphere westerlies since the last ice age. Nice job Meghan!
