  • Roundup: Penguins, Antarctica, and Geological Games

    Roundup: Penguins, Antartica, and Geology Board Games Looking for New Emperor Penguin Colonies From ScienceDirect: “Knowledge about the abundance and distribution of the emperor penguin is far from complete despite recent information from satellites. When exploring the locations where emperor penguins breed, it is apparent that their distribution is circumpolar, but with a few gaps between known colonies.…

  • Roundup: Chemistry, Dams and Elevations

    Roundup: Meltwater Chemistry, Hydroelectric Dams and Glacier Elevation   Diurnal Changes in the Chemistry of Glacier Meltwater From Chemosphere: “An evaluation of glacial meltwater chemistry is needed under recent dramatic glacier melting when water resources might be significantly impacted. This study investigated trace elements variation in the meltwater stream, and its related aquatic environmental information, at…

  • Iceberg Killing Fields Threaten Carbon Cycling

    Ryder Bay is helping mitigate impacts of climate change through removing carbon from the atmosphere to the ocean, where they can remain for centuries.

  • Small Particles Have Big Impact on Glacial Health

    A recent study by Heidi Smith et al. in the desolate McMurdo Dry Valleys of Antarctica has shown that microbial life in biofilms is present across a large part of the region’s ice, suggesting that the stability of polar ice can be influenced by even the smallest of organisms. Biofilms—thin, slimy bacterial layers that can…

  • Creating the World’s First Ice Core Bank in Antarctica

    Glaciers contain valuable information about past environments on Earth within the layers of ice that accumulate over hundreds or thousands of years. However, alpine glaciers have lost 50 percent of their mass since 1850, and projections suggest that glaciers below 3500m will not exist by 2100. Concerns about the loss of this valuable resource motivated…

  • Prominent Scientist Gordon Hamilton Dies in Antarctica

    Gordon Hamilton, a respected glaciologist, died recently while on field research in Antarctica after his snowmobile fell 100 feet into a crevasse. The 50-year-old associate research professor worked at the University of Maine where he studied the effects of climate change on the shrinking glaciers of Greenland and Antarctica. Dr. Hamilton had been conducting field…

  • Photo Friday: The Glaciers of Antarctica

    Antarctica, the world’s southernmost continent, is a hostile realm of ice and snow, fictionalized in our popular culture by the likes of H.P. Lovecraft and further romanticized by real-world scientific explorers eager to lay claim to the region. Humans who venture to the southernmost pole do so by way of the Antarctic Peninsula, where they…

  • Roundup: Antarctica and Greenland in peril, black carbon

    Ninety percent of the western Antarctic Peninsula’s glaciers are retreating From Carbon Brief: “These rivers of ice ooze their way down through the Peninsula’s rocky mountain range and into the ocean, powered by gravity and their own weight. But of the 674 glaciers on the Peninsula’s western side, almost 90% are retreating. This happens when their…

  • Intimacy and Expertise: A Conversation with Antarctic Anthropologist Jessica O’Reilly

    When most people think about Antarctica, they do not think about people.  That is not the case for Jessica O’Reilly, assistant professor of international studies at Indiana University.  In her April 2016 paper, “Sensing the ice: field science, models, and expert intimacy with knowledge,” published in theJournal of the Royal Anthropological Institute, O’Reilly explores the…

  • Roundup: Glacial Melt, Photos, and Disasters

    Each week, we highlight three stories from the forefront of glacier news. The Climate Post: Melting of Totten Glacier Could Trigger 6 Foot Sea-Level Rise From Huffpost Green: “A new study published in the journal Nature is drawing attention to the effect of warming water on the world’s largest ice mass, Totten Glacier in East Antarctica. Melting of…
