Rüdiger Escobar-Wolf Comments on Fuego Pyroclastic Flow

Volcan de Fuego day and night imagesOn June 3, 2018, torrents of hot ash, rock, and gas poured down ravines and stream channels on the slopes of Volcán de Fuego—Guatamala’s Volcano of Fire. More than three weeks after the eruption, the Landsat 8 satellite continued to detect elevated temperatures in some of the pyroclastic flow deposits.

“Fuego left pyroclastic flow deposits that cooled down quickly at the surface but are still very hot inside,” explained Michigan Technological University volcanologist Rüdiger Escobar-Wolf. “Cooling deposits can show surface temperatures above the background level for a long time—weeks, or even months. However, that temperature may be only slightly above the background level, as the heat from the interior slowly seeps out of the deposit to the surface.”

Presentation on How the Rock Connects Us

How the Rock Connects Us coverErika Vye and Bill Rose will give a presentation on how Isle Royale and the Keweenaw Peninsula have a rich cultural, industrial, and mining heritage, all connected by their geologic underpinnings.

The topics are showcased in their new book, How the Rock Connects Us: A Geoheritage Guide to Michigan’s Keweenaw Peninsula and Isle Royale, published by the Isle Royale Natural History Association, Incorporated, Nov 24, 2017 – 64 pages. ISBN 0935289216, 9780935289213

Interested in exploring the geology of the Keweenaw and Isle Royale this summer? Join Erika Vye and Bill Rose to learn about exciting geosites in our area, upcoming tours, and how to navigate their new geoheritage field guide. Daniel Lizzadro-McPherson will also join to showcase a Story Map he developed highlighting Isle Royale geology during a National Park Service Geoscientist in the Park internship. The book will be available for sale, and proceeds from this sale will support library services.

This event is sponsored by the Friends of the Calumet Public Library.

The book signing and presentation will take place at on Wednesday, June 27, 2018, from 6:30 to 8 p.m. at the Calumet Public Library.

Greg Waite is an Outstanding Reviewer

Greg Waite
Greg Waite

Greg Waite (GMES) was among the “Outstanding Reviewers of 2017” named by Eos, Earth & Space Science News. According to the American Geophysical Union (AGU), the reviewers listed “have all provided in-depth evaluations, often over more than one round of revision, that greatly improved the final published papers. This increase in complexity, in turn, has increased the challenge and the role of reviewing.”

Winning reviewers were selected by the editors of each journal for their work. Editor M. Bayani Cardenas cited Waite for his service to Geophysical Research Letters.

Quality peer review is thus a critical part of the social contract between science and society.Eos

Bornhorst Talks About the Midcontinent Rift

Institute on Lake Superior Geology

Ted Bornhorst, executive director of the A. E. Seaman Mineral Museum, attended the 64th annual meeting of the Institute on Lake Superior Geology held May 15 to 18, 2018, in Iron Mountain. Bornhorst gave a presentation during the technical sessions titled “The youngest magmatic activity of the Midcontinent rift at Bear Lake, Keweenaw Peninsula, Michigan.”

The presentation was co-authored by Evgeniy Kulakov, University of Oslo, Chad Deering (GMES) and Jim Moore. Bornhorst also served on the 2018 institute’s board of directors that met during the meeting. Darlene Comfort, Office of the Vice President of Administration, served as registrar for the meeting through the museum.

Simon Carn on Kilauea Emission

Simon Carn (GMES) was quoted in the article “Sulfur Dioxide Leaks from Kilauea” in Earth Observatory. The article looks at the impact of the eruption and lava flow from the Kilauea volcano in Hawaii.

Sulfur Dioxide Leaks from Kilauea

Kilauea has been erupting continuously since 1983, but in late April and early May 2018 the volcanic eruption took a dangerous new turn.

In addition to seismic activity and deformation of the land surface, another sign of volcanic activity is increased emission of sulfur dioxide (SO2), a toxic gas that occurs naturally in magma.

“Interpreting the satellite SO2 data for events like this is complicated because there are multiple SO2 sources that combine to form the volcanic sulfur dioxide plume,” said Simon Carn, a volcanologist at Michigan Tech.

In the News

Simon Carn (GMES) was quoted in the article “The lava striking the sea is gorgeous — and can be deadly,” in The Verge. Carn commented on the results when lava from a volcano strikes seawater. The story was picked up by several media outlets including the Las Vegas News and Dotemirates.

Simon Carn (GMES), was quoted in the article “Kilauea Lava Flows Hit the Ocean, Creating Toxic Acid Steam Clouds” which looks at the effects of lava from the Kilauea Volcano hitting the ocean. Research from Michigan Tech regarding the volcano was mentioned in Radio Canada.


Mark Kulie Presents on Global Snowfall Datasets

Mark Kulie (GMES) is attending the NASA CloudSat/CALIPSO Annual Science Review meeting in Boulder, Colorado. The meeting runs April 23-25, 2018.

Kulie will present a talk entitled “Modern Global Snowfall Datasets: CloudSat’s Contribution.” This talk summarizes many recent and ongoing collaborative projects to develop and optimize global snowfall datasets using satellite observations.

In Print

Mark Kulie (GMES) and Lisa Milani (GMES) recently authored a manuscript entitled “Seasonal variability of shallow cumuliform snowfall: A CloudSat perspective“. This article was published in the Quarterly Journal of the Royal Meteorological Society. The study illustrated the global seasonal cycle of lake/ocean-effect snow using satellite-based radar observations.

https://doi.org/10.1002/qj.3222

Extract: Cumuliform snowfall seasonal variability is studied using a multi‐year CloudSat snowfall rate and cloud classification retrieval dataset. Microwave radiometer sea ice concentration datasets are also utilized to illustrate the intimate link between oceanic cumuliform snowfall production and decreased sea ice coverage.


Simon Carn Discusses the Ambae Volcano

Simon Carn (GMES) was cited in the article “Ambae volcano ERUPTION: Mass evacuations ordered as volcano threatens to blow,” in Express. The article deals with the increased activity and potential evacuation of thousands of households near the Ambae volcano on the island nation of Vanuatu in the South Pacific.

Ambae volcano ERUPTION: Mass evacuations ordered as volcano threatens to blow

A large sulphur dioxide plume was emitted from Ambae in early April and it may have emitted the most sulphur dioxide of any eruption since the 2015 eruption at Calbuco in Chile.

It was noted by Simon Carn, a volcanologist and professor at Michigan Tech.

Dr Carn said a significant amount of ash was emitted during one of these eruptions and pictures on Twitter show the extent of ash on the island, which suggested it was a pretty large eruption.

Ambae volcano is a very large volcano and is frequently active. In its recorded history there have been many eruptions – every 10-50 years over the past 150 years.

All these eruptions have been from the summit craters, except one recorded in the 1670s.

Jackie Huntoon on Teaching Earth Science

Michigan Tech Provost and Vice President for Academic Affairs Jacqueline Huntoon was interviewed for the article “The Importance of Teaching Earth Science,” reprinted in teachmag.com. The article originally appeared in the Jan./Feb. 2018 edition of TEACH Magazine.

The Importance Of Teaching Earth Science

Earth science has long been the poor cousin of STEM programs. It takes a back seat to technology and even among the straight sciences, rocks and rivers get short shrift alongside the physical sciences—properties of matter, motion, gravity.

“A lot of the topics that are part of an earth science curriculum are relevant to a person’s daily life,” said Jacqueline Huntoon, provost at Michigan Technological University. She has been helping to develop the new middle school science curriculum Mi-STAR, for Michigan Science Teaching and Assessment Reform.

Her approach relies heavily on hands-on experience.

“In the past students would be asked to memorize 50 different minerals or some set of chemical formulas. That’s not really intriguing or interesting to every kid on the block,” she said. “We like to start with something tangible and concrete, so that all the students can have a shared experience. We’ll look at those ‘helicopter’ seed pods, for example. When you drop them, they spin. Why do they spin? You can make a model of that. You get the kids to figure out as of much of this on their own, with the teacher as a guide, before you start lecturing about the concepts.”
