Ted Bornhorst, executive director of the A. E. Seaman Mineral Museum, and professor (GMES) recently published an article in Minerals – an Open access Mining and Mineral Processing Journal. Bornhorst’s article was titled “Copper isotope constraints on the genesis of the Keweenaw Peninsula native copper district, Michigan, USA” and was co-authored by Ryan Mathur, professor and chair of geology at Juniata College in Huntingdon, Pennsylvania.

Abstract

The Keweenaw Peninsula native copper district of Michigan, USA is the largest concentration of native copper in the world. The copper isotopic composition of native copper was measured from stratabound and vein deposits, hosted by multiple rift-filling basalt-dominated stratigraphic horizons over 110 km of strike length.

How Earthquakes and Volcanoes Reveal the Beating Heart of the Planet

The Smithsonian Global Volcanism Program has stitched together a visual archive of the world’s earthquakes and volcanoes

To illustrate these dynamic patterns, the Smithsonian Institution’s Global Volcanism Program, hosted within the National Museum of Natural History, has created a time-lapse animation of the world’s earthquakes, eruptions and emissions since 1960. Drawing from the first compiled database of sulfur emissions dating to 1978, the animations show how the seemingly random activity of volcanoes and earthquakes form consistent global patterns over time. Understanding those patterns gives researchers insight into how these dramatic events are entwined with the inner workings of our planet.

Earthquakes and volcanoes can conjure up images of widespread destruction. But for those who study Earth’s deepest reaches, like Elizabeth Cottrell, a research geologist at the Smithsonian’s National Museum of Natural History and director of the Global Volcanism Program, volcanoes are also “windows to the interior.”

“Global satellite monitoring of volcanoes will transform our understanding of gas fluxes from Earth’s interior to exterior in the coming decade,” says Cottrell, who has been working along with Michigan Tech researcher Simon Carn and data manager Ed Venzke to incorporate volcanic emissions into the Smithsonian database since 2012.

A geologist with the University of Kerala has collaborated with a U.S.-based geological engineer to prepare the Landslide Atlas of Kerala. The atlas, co-authored by K.S. Sajinkumar, Assistant Professor, Department of Geology, University of Kerala, and Thomas Oommen, Associate Professor, Michigan Technological University, U.S., depicts the spatial and temporal distribution of landslips and potentially hazardous locations in the Western Ghats.

The atlas, prepared after an extensive mapping process that lasted for a year, has used the latest tools of Geographic Information Systems (GIS)

Public Works Minister G. Sudhakaran will formally launch the Landslide Atlas of Kerala at the Department of Geology on the Karyavattom campus of the university on September 19, 2017. The Geological Society of India is the publisher of the atlas.

What effects do earthquakes have on volcanoes?

The interaction between earthquakes and volcanoes intrigues the public and provides a complex and cascading hazard that challenges scientists across a spectrum of disciplines. The key to understanding earthquake-volcano interactions is the response of gas and magma to earthquake-imposed stresses.

Mark Kulie (GMES/GLRC) is attending the American Meteorological Society 38th Conference on Radar Meteorology this week (August 28 to September 1, 2017) in Chicago.

He will present a talk entitled “Seasonal Variability of Shallow Cumuliform Snowfall: A CloudSat Perspective” in the “Moving Platforms. Vehicle, Airborne, Shipborne and Spaceborne: Satellite” session. He is also co-chairing the “Cloud Studies Using Radars” conference session.

Founded in 1919, the American Meteorological Society (AMS) is the nation’s premier scientific and professional organization promoting and disseminating information about the atmospheric, oceanic, hydrologic sciences.

Mark Kulie (GMES/EPSSI) is the principal investigator on a project that has received an $86,255 research and development grant from the NASA. The project is entitled “Snowfall in the GPM Era: Assessing GPM Snowfall and Ice Microphysical Retrievals Using Independent Spaceborne and Ground-Based Observations.” This is the first year of a potential two-year project totaling $186,255.

Chad Deering (GMES/EPSSI), is the principal investigator on a project that has received a $250,718 research and develop grant from the National Science Foundation.

The project is titled “Assessing Changes in the State of a Magma Storage System Over Caldera-Forming Eruption Cycles, a Case Study at Taupo Volcanic Zone, New Zealand.”

This is the first year of a potential three-year project which could total $349,665.

ABSTRACT

The largest volcanic eruptions are rare events but can represent a global catastrophe. Smaller eruptions may still have significant (billions of dollars) economic impacts and may affect the lives and livelihoods of large numbers of people, even in places distant from the erupting volcano (e.g., the relatively small eruption in Iceland in 2010). This project focuses on the Taupo Volcanic Zone (TVZ) in New Zealand as a case study of a large and very active volcanic system, and will focus on developing a better understanding of how the temperature and mobility of a magma body below the surface changes before, during, and after a major eruption. This study will contribute to our understanding of the volcanoes that produce such large eruptions (for example, Yellowstone volcanic system in the US), and will provide critical context for interpretation of real-time hazard monitoring at these and other active volcanoes. In addition, the project will include research experience for a K-12 teacher and development of new standard-based physics, chemistry and mathematics curriculum that will be disseminated broadly.

The Ontario Geological Survey, Ministry of Northern Development and Mines and the A. E. Seaman Mineral Museum teamed up to co-host the 63rd Annual Institute on Lake Superior Geology held in Wawa, Ontario May 8-12.

This professional meeting consisted of two days of technical sessions with 29 oral and 22 poster presentations. There were three geological field trips before the technical sessions and three after.

The meeting was attended by 137 geologists from the US and Canada. Academic institutions (58 members), government agencies (28 members), and mining and consulting companies (36 members) were well represented among attendees.

Margaret Hanson, museum assistant director, served as registrar for the meeting while Ted Bornhorst, museum executive director and professor, organized the meeting sessions, handled finances and decided on travel awards to students.

The Institute publishes technical volumes in hard copy for each meeting and offers them open-access online after the meeting is completed.

Bornhorst and Hanson co-edited the Institute on Lake Superior Geology, Proceedings Volume 63, Part 1: Program and Abstracts (97p.). They also compiled Part 2: Field Trip Guidebook (204p.).

The Institute is well regarded for its high quality field trips having recently won a national award from the Geoscience Information Society for the Outstanding Geologic Field Trip Guidebook Series.

The Institute initiated a new annual award for 2017, Pioneer of Lake Superior Geology, to recognize those individuals who made significant contributions to the understanding of the geology of the Lake Superior region primarily prior to the Institute’s awarding of the prestigious annual Goldich Medal in 1979.

The first Pioneer of Lake Superior Geology is Douglass Houghton (1809-1845). Bornhorst nominated Houghton for the award and wrote, along with Larry Molloy, President of the Keweenaw County Historical Society, the two-page biographical sketch published in the Proceedings Volume. As the first speaker for the technical sessions, Bornhorst provided the highlights of the important attributes that contributed to Houghton’s success.
