Most Volcano Cross-sections You See Are Wrong

Forget the big red blob that we've all sketched under the triangle cone of a volcano in ninth grade earth science. Magma chambers just aren't that simple. 

Evidence over the last decade or so has increasingly shown that instead of being an underground lava lamp of molten rock, magma is more of a crystal mush. A new study published in Science not only supports this but also reveals that magma may be cooler and more solid than previously thought. 
An international team of researchers from UC Davis, Michigan Tech, Arizona State, Oregon State, Nanyang Technical University in Singapore, and University of Canterbury in New Zealand gathered and analyzed zircon crystals expelled in 1314 eruption in New Zealand. The crystals record the thermal and chemical history of its surprisingly long stay in the magma reservoir.

They are students of Jason Blough (ME-EM) and Andrew Barnard (ME-EM). 
On Wednesday, Michigan Tech students won 11 awards between the two conferences:
  • SAE NVC Best Student Paper—First place: Troy Bouman, Second Place: Mahsa Asgarisabet
  • INCE-USA NoiseCon Best Student Paper—Micaela Theiry and Trinoy Dutta 
  • INCE-USA Hallberg Foundation Travel Award—Theiry, Miles Penhale, Siddharth Parmar, Suraj Prabhu and Asgarisabet
  • Beranek Gold Medal for Excellence in the Study of Noise Control Engineering for an Undergraduate Student—Stephania Vaglica
  • Beranek Pewter Medal for Excellence in the Study of Noise Control Engineering for a Graduate Student—Asgarisabet
The students also had a booth in the expo where they showed off some of their work and it was busy with visitors for two straight days. 

Graduate School Announces Pilot Model for GACS

In response to budget constraints, cost share changes within federal agencies, and to incentivize PI’s to include graduate student support in sponsored research projects, a pilot model for Graduate Assistant Cost Share (GACS) has been rolled out that will be effective June through August 2017.

The current model offers automatic GACS support when cost share is mandatory. The GACS support is in the form of summer support (stipend plus minimum full-time tuition [one credit]). 

The piloted GACS model will be in the form of year-round tuition support. The dollar amount of tuition depends on the PI's requested direct costs on a project. 

Requested direct costs of $25,000 - $100,000/year (annual average direct costs): 

  • GACS will provide 100 percent of tuition support (fall, spring, and summer semesters; nine credits for fall and spring and one credit for summer). 

Requested direct costs of $101,000 - $200,000/year (annual average direct costs): 

  • GACS will provide a maximum of 50 percent of tuition support (fall, spring, and summer semesters; nine credits for fall and spring and one credit for summer).

Requested direct costs of $201,000 - $350,000/year (annual average direct costs): Annual GACS tuition support is available only if cost share is mandatory.

Michigan Tech at Annual Meeting of the Society for Freshwater Science

Michigan Tech was well represented at the annual Meeting of the Society for Freshwater Science in Raleigh, North Carolina June 4-8.

Amy Marcarelli (Bio Sci) and six students from the Department of Biological Sciences presented their research results (listed below), participated in society business, networked with colleagues, and performed an awesome rendition of  "Take Me to the River" for a karaoke live auction item with friends from Idaho State University (including lab and Tech alumni Jade Ortiz, BS 2015).

Marcarelli also began a one-year term as vice president of the society, appointed to serve with incoming president Colden Baxter. You can read more about the meeting and travel exploits (including the road trip down and back and field work before the meeting) on the lab field blog.

Rail Transportation Program to Co-host Midwest Conference

The Michigan Tech Rail Transportation Program is among the hosts of the Midwest Rail Conference in August. Co-sponsors include the Michigan Department of Transportation (MDOT) and a group of organizers. 
Formerly the Michigan Rail Conference, this newly-expanded program now has a regional focus with co-organizers, like the Freight Rail Transportation Committee (AR040) of the Transportation Research Board and the National University Rail Center (NURail). 
AR040 also is bringing their Summerail 2017 event, and NURail will add their annual meeting to the event. The theme of this year's conference is "Midwest Connections: Passenger and Freight Rail Look to the Future!" #MWRailConference.
The conference gathers rail industry representatives and supporters to discuss issues and opportunities for Midwest rail activity. This year’s conference will be held from Aug. 15-17 at the Fetzer Center in Kalamazoo, Michigan.
There will be technical presentations, panel discussions and a networking reception. Joseph McHugh, senior vice president and chief for Amtrak Government Affairs and Corporate Communications will provide the keynote address.
The conference is open to anyone interested in the rail industry, but should be of particular interest to federal, state and local government representatives, transportation industry professionals, colleges and universities, the interested public, students and the media. 
The conference organizing committee is offering students a limited number of scholarships to cover the conference registration and field trip fees. The early bird registration rate has been extended until Friday June, 30.
Detailed conference information and links for registration can be found on the conference website
