Renown physicist and alumnus to speak at Moravian College

Dr. H.J. Trodahl, an internationally renowned physicist and visiting professor from Victoria University of Wellington, New Zealand, is visiting Moravian College this week to meet with professors and students. A highlight of his visit to Moravian College will be Dr. Trodahl’s discussion of his work in Antarctica and his study of sea ice and its affect on the world. The lecture will be held on Wednesday, January 20th, at 4:00 p.m. in Dana Lecture Hall.

At the lecture, Dr. Trodahl will describe the special structure of sea ice and experimental studies of those properties which influence primary biological production and the

weather. The annual formation of vast areas of sea ice around the Antarctic continent greatly affect deep ocean changes and currents, and weather patterns worldwide. Dr. Trodahl will discuss the changes in the ozone hole and global warming and its affect on sea algae and the ecosystem.

Dr. Trodahl graduated from Moravian College in 1963 with a B.S. in physics. He earned his Ph.D. in physics from Michigan State University in 1968. Dr. Trodahl has led a distinguished career as a professor of physics at the University of Wellington, New Zealand. His research has been in several fields of physics: solid state physics; investigations of sea ice in Antarctica; and superconductivity for which he has achieved considerable recognition. He has been a visiting research scientist at University of British Columbia, Vancouver; Norwegian Institute of Technology, Norway; Max-Planck Institute, Germany; and Chalmers Institute of Technology, Sweden.

The lecture is open to the public and admission is free. Dana Lecture Hall is located on Moravian College’s Main Street Campus at the corner of Locust and Main streets in Bethlehem, PA. For more information, call (610) 861-3916.
