Aleksey Smirnov (GMES) is a co-author on the paper “Paleomagnetic evidence for modern-like plate motion velocities at 3.2 Ga” published in Science Advances on April 22, 2020. This collaborative study (with Harvard University and Yale University) demonstrates that the drifting of tectonic plates (plate tectonics) may have started at least 3.2 billion years ago, earlier than previously thought.
Plate tectonics has been the dominant surface geodynamical regime throughout Earth’s recent geological history. One defining feature of modern plate tectonics is the differential horizontal motion of rigid lithospheric plates
The mode and rates of tectonic processes and lithospheric growth during the Archean [4.0 to 2.5 billion years (Ga) ago] are subjects of considerable debate. Paleomagnetism may contribute to the discussion by quantifying past plate velocities.
While plate tectonics have characterized Earth’s geodynamics in recent geologic time, it is unknown whether long-range horizontal motion of lithospheric plates occurred before ~2.7 Ga. Resolving this uncertainty would fundamentally contribute to understanding the formation settings of Earth’s earliest crust and nascent biosphere and the evolution of geodynamics in terrestrial planets in general.

Simon Carn (GMES) was quoted in the article “Map shows Taal Volcano spewing sulfur into atmosphere,” in the Philippine Star. Carn was also quoted in “Taal volcano eruption: NASA satellite scans reveal TOXIC sulphur clouds spewing from Taal,” in the Express (UK).
Although the levels of SO2 released by Taal have so far been tolerable, Michigan volcanologist Simon Carn fears more of the toxic gas could be still be released.
He said: “However, it is possible that the Taal eruption could continue and produce more SO2 in the coming days.”

PITTSBURGH—Residents of the Mon Valley, a cluster of townships along the Monongahela River 20 miles south of Pittsburgh, Pennsylvania, endured some of the stinkiest and most polluted air in the nation this Christmas.
Some experts say that trend is likely to continue, and that cities around the world could see an influx of similar “super pollution events” as Earth continues to warm.
“For the last at least 60 years we have data for, we can clearly see a trend of increasing temperature inversions in midlatitude regions,” Shiliang Wu, an atmospheric chemist and associate professor at Michigan Technological University, told EHN. “I believe this trend will continue in the coming decades, which will likely lead to an increase in extreme air pollution episodes.”

Don Lafreniere (SS/GLRC), Ryan Williams (GLRC), Dan Lizzadro-McPherson (GMES/GLRC), and students from the Advanced GIS Methods class attended the NSF funded Coastlines and People Workshop hosted at Northern Michigan University on December 6, 2019. The Coastlines and People workshop series is working to bring scientists and stakeholders together to produce a vision for the future of sustainable coastal development in an era of dynamic climate change.
Lafreniere, Williams, and Lizzadro-McPherson introduced attendees to several projects underway at the Michigan Tech Geospatial Research Facility including the Keweenaw Time Traveler (NEH), 300 Years of Francophone Migration (SSHRC), Keweenaw Fault Mapping (USGS), and Historic Coastlines of Michigan mapping projects (EGLE). The workshop featured additional presentations from NMU and Michigan State University faculty, as well as welcome messages from the Mayor of the City of Marquette and the President of Northern Michigan University. All presentations were well received by nearly 75 attendees. Additional workshops are scheduled in 2020.
Earlier this year, astronauts in the International Space Station got a front row seat for an epic event, but it wasn’t happening in space. On June 22, the astronauts looked down at the earth and saw the Raikoke Volcano erupting , which led to some incredible images captured by NASA and other satellites.
“What a spectacular image. It reminds me of the classic Sarychev Peak astronaut photograph of an eruption in the Kuriles from about ten years ago,” said Simon Carn, a volcanologist at Michigan Tech, in a NASA statement about the volcanic eruption . “The ring of white puffy clouds at the base of the column might be a sign of ambient air being drawn into the column and the condensation of water vapor. Or it could be a rising plume from interaction between magma and seawater because Raikoke is a small island and flows likely entered the water.”
Research Professor Bill Rose and Geoheritage Education Coordinator Erika Vye presented the paper “UNESCO Recognition of Jacobsville Standstone as Global Heritage Stone Resource Buoys Keweenaw Geoheritage Efforts” at GSA 2019, the Geological Society of America annual meeting.
The presenters stated that the International Union of Geological Sciences (IUGS) and the United Nations Educational, Scientific and Cultural Organization’s (UNESCO’s) International Geoscience Programme (IGP) have announced that the Jacobsville Sandstone, a rock formation named for Jacobsville, Michigan, is now one of the first 15 Global Heritage Stone Resources (GHSR) in the world and the first in the United States.
They discussed the history of the natural stone in the copper country and noted the impact of international recognition upon the awareness of geoheritage.
The 2019 meeting was held September 22-25 in Phoenix, AZ.
In early August, sailors in the southwest Pacific Ocean began to see their environment transmogrify. As far as the eye could see, the ocean turned from an azure delight into a colossal gathering of clinking, floating rocks. And then came the foul, sulfurous odors.
Satellite images—plenty of which were shared on Twitter by Simon Carn, a volcanologist at Michigan Technological University—showed a giant pumice raft twisting and warping in the open ocean, pushed around by the winds and waves. The raft covered an area a bit larger than San Francisco.
