Martin Jeffries, Research Professor; University of Sheffield, ’79 B.A. (Hons.); Victoria University of Manchester, ’81 M. Sc.; University of Calgary, ’85 Ph.D. Jeffries joined the Geophysical Institute as a post-doctoral fellow in 1985 and has held his current position of research professor since 1998. A member of the Snow, Ice and Permafrost Group, Jeffries has studied the structure and growth history of arctic ice shelves and icebergs, the isotope geochemistry of density stratified water bodies in the Canadian High Arctic, sea ice formation and thickness in the Arctic and Antarctic, and lake ice/atmosphere/land interactions in Alaska. Currently, his research focuses on measurement and modeling of lake ice growth and decay in Alaska, and snow and ice research experiences for K-12 teachers as a means to promote professional development and inquiry-based learning in the local context. In collaboration with the UAF School of Education, Jeffries offers professional development classes on snow, ice and K-12 curriculum. He is the chairman of the Advisory Board of the National Science Foundation program “Teachers Experiencing Antarctica and the Arctic,” and is on the advisory committee for the Office of Polar Programs. Jeffries also is on the editorial boards of the journals Arctic and Polar Record.

Lecture Presentation:

Data Analysis and Interpretation
Presented Apr. 13, 2006
Lecture Summary
(click here)
Martin Jeffries, Research Professor of Snow, Ice, and Permafrost at the Geophysical Institute explains basic types of graphs and how to interpret them. Jeffries uses examples from ALISON (Alaska Lake Ice and Snow Observatory Network) to show types of graphs and methods of interpretation, and demonstrate how the relationships between snow depth and ice thickness. His lecture also covers graphical analysis and how it can be used to make conclusions directly and indirectly. The lecture is followed by questions from students and teachers in the Bering Strait School District.
