  • Roundup: New Bacteria, Poetic Shasta, and Glacial Melt

    New Bacteria Discovered at Tibetan Glacier From Microbiology Society: “A cold-tolerant, translucent, yellow-pigmented, Gram-stain-positive, non-motile, rod-shaped bacteria was isolated from snow of the Zadang Glacier on the Tibetan Plateau, PR China. 16S rRNA gene sequence similarity analysis indicated that the isolate was closely related to Conyzicola lurida KCTC 29231T and Leifsonia psychrotolerans DSM 22824T at a level of 97.72 and 97.49 %, respectively.…

  • Photo Friday: Monitoring Chile’s Volcanoes

    Currently, three volcanoes in Chile are restless, according to the Servicio Nacional de Geología y Minería. A “class yellow” status for these glacier-covered peaks means elevated seismic activity and higher potential for eruption. The ice caps on these giants mean that an eruption could spur Jökulhlaups, glacial outburst floods that can be extremely dangerous, such as in…

  • Driving the Dalton: A Tour of North Slope Glacial History

    The only road in the United States that crosses the Arctic Circle is the Dalton Highway: a remote, potholed, perilous path that begins north of Fairbanks and terminates at the Arctic Ocean. For some, driving the Dalton is a bold, lonely adventure, and for others, it’s just a long commute to work. Molly Timm, field…

  • An Interview on Patagonian Imaginaries

    A recent paper in the Journal of Latin American Geography, “The Patagonian Imaginary: Natural Resources and Global Capitalism at the Far End of the World,” analyzes the construction of southern Andean Patagonia as an “ecoregion,” a label that has come to dominate the representation of the glaciated territory of Chile and Argentina. Through this representation, resource…

  • Roundup: Antarctic Coral, Laser Ultrasound, and Totten Glacier

    Ecology of Antarctic Coral From Science Direct: “Antarctic ecosystems present highly marked seasonal patterns in energy input, which in turn determines the biology and ecology of marine invertebrate species. The pennatulid Malacobelemnon daytoni, is one of the most abundant species in Potter Cove, Antarctica. Its biochemical compositions were studied over a year-round period. The profiles suggest…

  • Photo Friday: Lake Issyk Kul

    Located high in Central Asia’s Tian Shan Mountains, Issyk Kul is one of the world’s largest alpine lakes. Though Issyk Kul literally means “warm lake” in the Kyrgyz language, the crystalline waters vary in surface temperature from as high as 73 degrees Fahrenheit in July to as low as 36 degrees Fahrenheit in January. Still, warmth is relative, and…

  • Arctic Field Science: An Unruly Harmony

    It’s 9 p.m. on my 26th birthday, and I’m standing outside a trailer in the middle of the Alaskan tundra. The trailer is my workplace for the summer, and my labmates and I are waving signs— mine reads “You are Alaska”— and cheering for the runners sprinting past us, in the final meters of an…
