Canadian Mineralogist issue in honor of Ed Grew

Related Links:

The current issue (v. 53, part 2) of the prominent mineralogical journal The Canadian Mineralogist has published an issue in honor of Ed Grew, on the occasion of his 70th birthday. Many papers in the issue come from colleagues with whom Ed has worked over the years. The introduction contains a great summary of Ed’s life and professional contributions. The cover depicts the crystal structure of the recently discovered mineral named edgrewite. The UMaine News site provides an extensive report.

Mongolia field work featured on Medill Reports Chicago

Related Links:

An article from Medill Reports Chicago this summer featured the Mongolia glacial geology field work of Aaron Putnam and Ph.D. student Peter Strand. The goal of the field work is to constrain the timing and spatial extent of glaciation in the region.

Cici Cruz-Uribe featured on Earth Science Women’s Network

A recent article in the Spotlight section of the Earth Science Women’s network features the School’s new Grew Assistant Professor Cici Cruz-Uribe. The article describes her research and her past and anticipated mentoring roles. We look forward to her work in support of gender and other forms of diversity.

More notice of Ed Grew’s involvement in mineral evolution and diversity research

Related Links:

In recent years, one of Ed Grew’s growing interests has been in the field of mineral evolution. This fairly new field explores when and where different mineral species have appeared over time, with a natural but not exclusive focus on terrestrial minerals. A recent Quanta Magazine article quoting Ed Grew and describing some of his collaborative work was highlighted in UMaine’s news blog.

Quanta Magazine’s mission is to enhance public understanding of research developments in mathematics and the physical and life sciences.

In addition to the Quanta Magazine article, Ed’s work received notable mention in an online article on that focuses on Earth’s mineral diversity.

Welcome to new members of the School: Cruz-Uribe, Putnam, and Allen

As we approach a new academic year, we are very pleased to welcome two new faculty members and a NOAA Fellow to our School. Both faculty members are the first to hold new, privately funded, named professorships in the school. We once again express our appreciation to the donors for these positions.

Aaron Putman is returning to UMaine (Ph.D., 2011) as the George H. Denton Professor. Aaron has spent the past four years at the Lamont-Doherty Earth Observatory, first as a Postdoctoral Research Scientist
 then as an Assistant Research Professor. Aaron’s research and teaching interests are broad, but focus on the interactions of Earth’s surface, cryosphere, and atmosphere. He is an internationally recognized scholar, having performed field work in Asia, South America, New Zealand, Antarctica, the U.S., and Europe. Aaron has published twenty-six papers, with more in review. Aaron’s wife, Katherine Allen, will also be joining us as a NOAA Climate and Global Change Fellow, working in the area of Geochemistry and Paleoclimate, particularly as they relate to ocean chemistry and biological activity.

Alicia (Cici) Cruz-Uribe is the Edward Sturgis Grew Professor in Petrology and Mineralogy. Cici comes to us after spending a year at the Woods Hole Oceanographic Institution as a Postdoctoral Investigator, following her Ph.D. at Penn State. Cici is primarily a metamorphic petrologist and geochemist, with a focus on kinetics and the chemical evolution of the mantle at subduction zones. She will establish a piston-cylinder experimental petrology laboratory beginning this fall. In addition to bringing new energy and expertise, her presence fills an important gap in petrology left by the retirement of Daniel Lux this year.

Abi Bradford featured in UMaine Today

Abi Bradford, a 2015 graduate of the School of Earth and Climate Sciences, is once again featured – this time in the UMaine Today article “Save the Snow”. The article describes Abi’s background and research experience working with Karl Kreutz on Alaskan glaciers.

Denton to receive a GSA Distinguished Career award

Related Links:

George Denton was recently announced as the recipient of the 2015 Quaternary Geology and Geomorphology Division of the Geological Society of America Distinguished Career Award. George will receive the award at a ceremony at the annual meeting of the Geological Society of America in Baltimore in November, where a fuller citation of George’s many accomplishments will be read. More information about the award is here.

New paper on Antarctica’s glacial history

Related Links:

Brenda Hall is the lead author on a new paper just published in Nature Geoscience, entitled “Accumulation and marine forcing of ice dynamics in the western Ross Sea during the
last deglaciation”. UMaine faculty and students George Denton, Stephanie Heath, Margaret Jackson, and Tobias Koffman are co-authors. This relatively new journal (established in 2008) has quickly risen to be one of the most respected journals in the field. The article is in the August 2015 issue, pages 625-628.

New study in Nature reveals rapid global temperature redistribution

Related Links:

School of Earth and Climate Sciences Professor Karl Kreutz, along with former UMaine graduate students Bess Koffman, Dan Breton, and Dominic Winski and Honors student Eliza Kane, participated in a recently published study of the West Antarctic Ice Sheet divide core. The study reveals that abrupt climate change that began in Greenland spread in ~200 years to the Antarctic, with ocean currents responsible for transferring the heat.

For more details, see the full UMaine news item:

The Nature article is at:

In that same issue is a paper co-authored by Kreutz’s former UMaine Honors student Matthew Kohler, now at the University of Washington. Matt’s study uses nitrogen isotopes to evaluate the origin of biological nitrogen fixation billions of years ago in Earth’s history.
