  • John Goodge '80 Is Drilling To The Bottom Of The Antarctic Ice Sheet

    December 17, 2015

    An Antarctic research project with close ties to the University of Minnesota Duluth has reached a major milestone in its quest to gather new scientific information from the depths of the ice-locked continent.

    The Rapid Access Ice Drill (RAID) — which researchers say will dramatically reduce the time required to bore deep into ice sheets — has been completed and is scheduled to be shipped to Antarctica this month.

    It'll be put to use as part of a research project involving researchers from UMD and the Scripps Institution of Oceanography. John Goodge, an earth and environmental sciences professor at UMD, is co-leader of the project that received a $9 million grant last year from the Division of Polar Programs at the National Science Foundation.

  • Noah Randolph-Flagg '11 Determines Origin Of Mysterious Stone Columns At Crowley Lake, CA

    November 15, 2015

    The strange pillar-like formation emerged after Crowley Lake reservoir was completed in 1941: stone columns up to 20 feet tall connected by high arches, as if part of an ancient Moorish temple.

    They had been buried and hidden for eons until the reservoir's pounding waves began carving out the softer material at the base of cliffs of pumice and ash.

    In the ensuing decades, the columns were regarded as little more than curiosities along the eastern shore of the Los Angeles Department of Water and Power reservoir, which is best known as a trout fishing hot spot about 10 miles south of Mammoth Lakes.

    But now answers are emerging from a study at UC Berkeley. Researchers have determined that the columns were created by cold water percolating down into — and steam rising up out of — hot volcanic ash spewed by a cataclysmic explosion 760,000 years ago

    "These columns are spectacular products of a natural experiment in the physics of hydrothermal convection," Noah Randolph-Flagg, 25, a PhD candidate and lead author of the study, said in an interview.

  • Jennifer Macalady '91 Discovers New Microbe In Dominican Republic Cave

    November 4, 2015

    In 2009 geomicrobiologist Jennifer Macalady got a phone call from a cave diver in the Dominican Republic who told her about a cave there with amazing curtains of slime. Her first thought was, “Who is this crackpot?” but she sent him a sample kit. “The sample he sent back to us was so interesting we knew we had to mount an expedition,” Macalady told Eos Monday. Macalady discussed the findings about these slime curtains in a talk Sunday at the Geologic Society of America’s 2015 meeting in Baltimore.

    During the expedition 2 years later, Macalady, who is with Pennsylvania State University in University Park, and her colleagues enlisted the aid of divers, whose video of their underground explorations shows rust-colored fronds of slime. These fronds descend from the ceiling and walls of some saltwater-filled chambers of a flooded cave in the country’s southeast called Manantial del Toro.

    Whereas the challenge and exotic beauty of Manantial del Toro attracts explorer-divers, the metabolisms of the slime curtains’ microbes lured Macalady. The microbial communities that inhabit these fingers of slime are specialized not only for nitrogen cycling but also iron cycling. Could a previously undiscovered microbe capable of both reducing nitrate and oxidizing iron hang from the walls of Manantial del Toro?

  • Stacy Tellinghuisen '00 Helps Explain Colorado Coal-Power Controversy

    August 20, 2015

    Long before the Obama administration cracked down on coal-fired power plant pollution, Colorado acted by itself. The state's pollution regulations made it a leader years ago. The state's Democratic governor still favors those rules, but the Republican state attorney general is on the other side and may join a lawsuit against the latest federal steps. [...]

    HOOD: The Obama administration says the plan will save the average family money. It may turn out that the politics over clean power are more complicated than actually producing cleaner energy. Stacy Tellinghuisen is an analyst with the conservation group Western Resource Advocates. She estimates the state is already committed to meeting three-fourths of the final goal.

    STACY TELLINGHUISEN: With no additional actions that aren't already in utilities' plans.

  • Kari Cooper '91, Cari Johnson '96 and Peter Reiners '91 Named GSA Fellows

    April 30, 2015

    We are particularly pleased to congratulate Kari Cooper '91, Cari Johnson '96 and Peter Reiners '91 who have been named Fellows of the Geological Society Of America.  They will be formally recognized at the Society's annual fall meeting in Baltimore on Nov. 1.

    Society Fellowship is an honor bestowed on the best of the profession by election at the spring GSA Council meeting. GSA members are nominated by existing GSA Fellows in recognition of their distinguished contributions to the geosciences through such avenues as publications, applied research, teaching, administration of geological programs, contributing to the public awareness of geology, leadership of professional organizations, and taking on editorial, bibliographic, and library responsibilities.

    Here are some comments from their nominators:

    Kari M. Cooper (University of California – Davis):
    Kari Cooper has made fundamental contributions to both the development of analytical techniques - most notably involving U-series nuclides - and the understanding of temporal and physical aspects of magma system histories. Her innovative work illuminates, among other key issues, how pre-eruption magma storage works: how long, and in what state?
    — Calvin F. Miller

    Cari L. Johnson (University of Utah):
    Dr. Cari L. Johnson, Associate Professor, University of Utah, is a prolific geologic researcher whose science covers a broad cross section of geology, including tectonics and sedimentation, sequence stratigraphy, and applications to petroleum source rock and reservoir systems. She is an excellent mentor of students, having received numerous teaching awards.
    — Stephan A. Graham

    Peter W. Reiners (University of Arizona):
    Dr. Peter W. Reiners is elected to GSA Fellowship on the basis of his fundamental contributions in developing (U-Th)/He thermochronometry, and applying low-temperature thermochronology to both reconstruct the tectonic evolution of many different regions of the world and examine a broad array of petrologic, structural, geochemical, erosional, and geodynamic processes.
    — George E. Gehrels

  • Sara Decherd Rutzky '01 Creates An Outdoor Geology Lab On Community College Campus

    April 14, 2015

    Raleigh, NC - Geology students at Wake Tech Community College have the chance to study large rocks from all over North Carolina without ever leaving campus.  The college introduced the Mountains to the Sea Outdoor Geology Lab at its northern campus on Tuesday. It features 12 boulders that came from as far west as Bessemer City in Gaston County all the way to Onslow County at the coast.

    “It’s a wonderful outreach into the community for geology,” said Sara Rutzky, a Wake Tech instructor who helped design and plan the project.

    Geology is the most popular lab science at Wake Tech, which is the largest community college in the state, said school President Stephen Scott... “Most of us geologists get into this wanting to be outside,” said Rachel Willis, a geology major from Knightdale. “There’s a big difference between reading about it and doing it.”

  • Walter Alvarez '62 et al Dinosaur Extinction Theory Debated

    January 31, 2015

    BOSTON — BY now the image of the demise of the dinosaurs has become iconic: a luckless tyrannosaur looking over its shoulder as a colossal fireball from heaven bears down on the horizon, the monster’s death by vaporization imminent.

    Hanging above the desk of the Princeton geologist Gerta Keller, though, is a different artist’s depiction. This time it’s a pair of tyrannosaurs — still doomed — but not by an errant space rock. In this picture they’re writhing on the ground in a withered landscape as eruptions from volcanoes and fissures in the ground tear the earth apart.

    These dinosaurs were killed not by the lava itself, but by the environmental catastrophe unleashed by the volcanic gases. [...]

    At a meeting in October of the Geological Society of America, Walter Alvarez patiently looked on as Dr. Keller presented her work dismissing his asteroid theory. When it was time for Professor Alvarez’s Berkeley collaborator, Mark Richards, to present his team’s paper, Dr. Richards admitted the destructive potential of the Deccan Traps and called their proximity in the fossil record to the asteroid “the 8,000-pound gorilla in the room.” Perhaps, he said, there was even a causal link between the asteroid — which induced a magnitude 12 earthquake — and the most destructive period of Indian volcanism.
