The impacts of volcanic eruptions can extend anywhere – from the immediate flanks of the volcano to regions thousands of kilometers downwind. This was brought starkly to the world’s attention during the eruption of Iceland’s Eyjafjallajökull volcano in April 2010.
In the Great Lakes region, as elsewhere, there are competing demands for a limited supply of water, including agricultural irrigation, public water supply, industrial production, and cooling in the generation of electricity.
Jet airplanes on Northern Pacific air routes fly over more than a hundred potentially active volcanoes. About ten days each year, volcanic eruptions create a fine ash— volcanic particles with a texture like flour and diameters smaller than 0.1 mm.
Creating a sustainable water system in Nicaragua
The Stan Dyl Geology Fellowship has been awarded to Elisa Piispa, a PhD student in geology, for her work on improving the proterozoic continental reconstructions based on combining characterizations of the paleomagnetism, geology, mineralogy and geochronology of mafic dike swarms in India. This fellowship will be used to support her travel to India to present her work. She is advised by Assistant Professor Aleksey Smirnov.
Joshua Richardson, MS student in geophysics, has been awarded the P. M. Thorton Endowed Fellowship for his work on emerging seismic structural imaging techniques involving active and passive source imaging of the upper crust. Josh has conducted seismic surveys at the Bering Glacier in Alaska and on Fuego Volcano in Guatemala. He is advised by Assistant Professor Gregory Waite.
Elisabet Head, PhD candidate in geology, has received the Seaman Museum Fellowship for her work on fluid inclusions in olivines erupted by Nyamuragira volcano. She is advised by Assistant Professor Simon Carn and the fluid-inclusion aspects were conducted in collaboration with Professor Paul Wallace at the University of Oregon.

For Alex Guth, being a graduate student is hardly a passive ordeal.
Recently, the Association for Women Geoscientists awarded the Brunton Award to Guth. This award, named for a top manufacturer of high-end compasses, is a prestigious commendation for work in field mapping and data acquisition. The award will include a personally engraved compass from Brunton.
“We are very proud of Alex’s work and are glad to see it recognized by a well respected organization like the Association for Women Geoscientists,” said Professor Wayne Pennington, chair of the geological and mining engineering and sciences department. Guth is pursuing a PhD in Geology.
Ancient “giant” spearheads and spindles have been discovered deep within New Jersey rock formations by a team of scientists.
These biominerals are actually about four microns long–hundreds would fit on the period at the end of this sentence. But they are much larger than those previously discovered and have huge potential regarding global warming yesterday, today and tomorrow.
These magnetofossils are new to the biomineral world, according to Michigan Tech paleomagnetist Aleksey Smirnov, a member of the research team. They discovered that 55 million years ago, the earth warmed by 6 to 8 degree Celsius after huge amounts of organic carbon entered the atmosphere. Although this ancient global-warming episode–the Paleocene-Eocene Thermal Maximum (PETM)–remains a mystery, it might offer analogies for future environmental impacts of possible global warming.
