2018 Summer School for Rock Magnetism

A Community Based Program for Training the Next Generation of Paleomagnetists

Magnetic geoscience research uses sensitive, nondestructive measurements on natural materials to illuminate geomagnetic field history, tectonic processes and environmental changes. Learn more about the fundamentals and applications at the fifth biennial Summer School in Rock Magnetism (SSRM), which will be held June 4-13th, 2018 at the Institute for Rock Magnetism (IRM) in Minneapolis, MN. The 10-day program is targeted at graduate students and advanced undergraduate students in rock magnetism, paleomagnetism, and associated fields. Students will receive intensive instruction in rock magnetic theory and laboratory techniques. A daily schedule of lectures, hands-on laboratory measurements, and data processing will introduce students to the fundamentals of rock magnetism and paleomagnetism and the practical aspects of collecting and interpreting data responsibly. Instructors for the summer school will be primarily IRM faculty and staff. We anticipate a special module on micromagnetic modeling taught by Wyn Williams, University of Edinburgh.

In addition to a $100 registration fee, participants will be responsible for the costs of housing, meals, and travel to and from Minneapolis. For students from outside the Minneapolis-St. Paul area, housing will be available in University of Minnesota dormitories (~$30-$50 per night), though the Summer School registration site.

A   limited number of scholarships ($200-$250) will be available to reimburse some of the costs for attending the summer program, thanks to funding from NSF-Geophysics and the GPE section of AGU. Participation will be li mited to 20 students, on a first-come first-served basis.

Registration for the Summer School is now open. Please follow this link to register. The registration deadline is April 30, 2018.

For more information please visit the 2018 Summer School in Rock Magnetism webpage. Information (Syllabus and Schedule) will be updated as they become available.

Update on the move to Tate Hall

Dear IRM users, fellows and aficionados,

As the solar eclipse was occurring on August 21st , the sun set permanently on our home in Shepherd Labs. The first phase of the move into Tate Hall was completed between August 21st and 23rd. All office and lab spaces have moved to their new locations and are now being set up. The sole hold out is the MPMS lab, which is scheduled to make the short trip on September 11th.

We are currently deep into the move's second phase: re-organizing the lab and setting up the instruments again. Everything is going as planned so far with no hiccups (knock on wood): plumbers and electricians are taking care of the necessary instrument hook-ups, vacuum pumps are running, while the kappabridges and Magnon are already functioning (though not yet online). The IRM database was not affected by the move and is still running, however, the internal IRM network is still not completely set up so "interactions" between the database and instruments are still off.

For the meantime, we remind you that the next Visiting Fellow application deadline is October 30th, and are looking forward to hosting the new batch of visitors in the new space, with spanking new offices, work stations and yes, a brand new shielded room!

You will still find the IRM on the second floor, but our new unified lab is located in room 240 of Tate Hall. The new mailing address for the IRM is:

Institute for Rock Magnetism
Department of Earth Sciences
University of Minnesota
150 John T. Tate Hall
116 Church St SE
Minneapolis, MN 55455

Phone numbers for the IRM faculty and staff have not changed.

Please bear with us as we complete the transition to Tate, including setting up the instruments, arranging spaces, updating the website and all of the other fine details. Looking forward to greeting you in the New Year, coffee is already brewing!

The state of the lab… view from the shielded room, across the open floor plan, to the backside of Tate onto Church Street. And yes, we have windows!


And one picture from Shepard Labs today: you may remember classical music playing in this office as you discussed rock-magnetism with Mike Jackson…

Special Issue for David Strangway

Call for submission of research papers in magnetism and electromagnetism to the Canadian Journal of Earth Sciences for publication in a special issue of tribute to Dr. David Strangway who died December 13, 2016.

David Strangway was born in Simcoe, Ontario, Canada, in 1934 and raised in Angola by missionary parents. He graduated in Physics and Geology in 1956 from the University of Toronto where he completed his MSc and PhD in magnetics research by 1960. After Assistant Professorships at the University of Colorado and Massachusetts Institute of Technology, he joined the National Aeronautics and Space Administration in 1970 as the head of the geophysics branch and leader of the "Moon rocks" research program. In 1973 Strangway returned to Toronto as Head of the Geology Department, and was later appointed Provost (1980) and President (1983) of the University of Toronto. In 1985 he began a successful twelve years as President of the rapidly growing University of British Columbia. In 1998, Strangway moved to Ottawa for six years as President of the government's new Canada Foundation for Innovation where he was responsible for dispensing $2.7 billion to Canadian universities for scientific research. Returning to British Columbia, Strangway founded Quest University, which opened in 2007. Today, this innovative liberal arts college has about 700 students. During his lifetime, Strangway held numerous important appointments and won many prestigious awards for his achievements. Above all, Dr. David Strangway was always a Renaissance man with broad-ranging interests and a great scientific curiosity.

This special issue of the Canadian Journal of Earth Sciences seeks to publish geophysical papers that report on any aspect of terrestrial and planetary magnetic or electromagnetic research. For magnetics, any of the categories listed in the "Current Articles" section of this issue of the IRM Quarterly will be suitable. The journal accepts papers from any country in English or French.

  • Deadline for providing tentative paper title: June 30, 2017
  • Deadline for submission of papers: March 30, 2018
  • Review, revision, and final acceptance: November 30, 2018
  • Tentative publication date of the special issue: January 2019

Please contact the Editorial Office of the Canadian Journal of Earth Sciences ( or Editor Ali Polat ( to submit the tentative manuscript title.

Thank you very much for your consideration, and we hope to hear from you soon.

Guest Editors David Symons (, David Dunlop (, and John Geissman (
