Dr. Melissa Hopkinson

Title: Part-Time Instructor, Geography, Geology, Earth Science

Office: Oconee
Areas of Expertise: Climatology, Paleoclimatology

Courses Taught

  • GEOG 1112 Introduction to Weather and Climate
  • GEOG 1112L Introduction to Weather and Climate Lab
  • GEOG 1111K Introduction to Physical Geography


  • Ph.D., Scripps Institution of Oceanography, University of California, San Diego
  • B.A., Northwestern University

Research/Special Interests

Dr. Hopkinson's research focused on the analysis of inert gas concentrations in air bubbles ice cores. She used these concentrations to determine climatic and oceanographic conditions during the last Ice Age. Specifically, she used the change in Kr/N2 and Xe/N2 ratios between the last ice age and today to approximate mean ocean temperature during the last ice age.

Personal Information

Dr. Hopkinson's favorite thing about the University of North Georgia is the feeling of community and openness among the students and faculty. Her favorite thing to do in the north Georgia region is to visit the north Georgia mountains in the fall to hike and see the leaves changing colors.
