  • Photo Friday: Inside Glacier Caves

    Caves can form within glaciers as a result of water running through or under a glacier. They are often called ice caves, but the term more accurately describes caves in bedrock that contain ice throughout the year. Water usually forms on the glacier’s surface through melting, before flowing down a moulin (vertical to nearly vertical shafts…

  • Roundup: Kyrgyz-Style Wakeboarding and Antarctica

    Roundup: Kyrgyz Wakeboarding and Antarctica Extreme Sports, Kyrgyz-Style From RadioFreeEurope: “Almaz Smailkulov, a Kyrgyz athlete, has taken wakeboarding to a new level, creating his own version of the sport.” You can view the video here.   East Antarctica’s Totten Ice Shelf is Warming From Nature: “On a glorious January morning in 2015, the Australian icebreaker…

  • Roundup: Putin’s Arctic Visit, Glacier Tours, and Pollutants

    Roundup: Putin, Glacier Tours and Pollutants Vladimir Putin Visits Arctic Glacier From The Telegraph: “President Vladimir Putin on Wednesday visited an Arctic archipelago, part of Russia’s efforts to reaffirm its foothold in the oil-rich region. On a tour of the Franz Josef Land archipelago, a sprawling collection of islands where the Russian military has recently built a new runway…

  • Glacier Retreat Exposes New Breeding Ground for Kelp Gulls in Antarctica

    Glacier retreat caused by anthropogenic climate change is often in the news because of its impacts on sea level rise and shrinking habitats. However, a recent study published by Lee et al. in the Journal of Ethology has found that glacier retreat on King George Island could have a positive impact on kelp gulls, exposing…

  • 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…
