  • Ice-core Evidence of Copper Smelting 2700 Years Ago

    The mysterious Moche civilization originated on the northern coast of Peru in 200-800 AD. It was known for its metal work, considered by some to be the most accomplished of any Andean civilization. But were the Moche the first Andean culture to originate copper smelting in South America? While the Moche left comprehensive archaeological evidence of an early…

  • 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.…

  • Photo Friday: Sperry Glacier

    Sperry Glacier is located 25 miles south of the border between the United States and Canada, in Montana’s Glacier National Park. It is a winter-accumulation glacier, as more snow falls during the winter than is lost during the summer. The moderate-sized glacier can be reached by foot or on horseback, rising to an elevation of around…

  • New Report Documents Pakistan’s Water Insecurity

    Water security is a pervasive issue in Pakistan, a largely arid country. The majority of the country receives less than 300mm of rain per year, while a small region in the north receives upwards of 1000 mm per year. The Indus River provides much of the water to the area, but its flow is irregular due…

  • Rock Glaciers Help Protect Species in a Warmer Climate

    In a recent study by Duccio Tampucci et al., rock glaciers in the Italian Alps have been shown to host a wide variety of flora and fauna, supporting plant and arthropod species during temporary decadal periods of climatic warming. Certain species that thrive in cold conditions have been prone to high environmental stress during warm…

  • Research Shows How Climate Change Drives Glacier Retreat

    Shrinking glaciers are oft-cited examples of the effects of anthropogenic climate change, providing dramatic imagery in different parts of the world. However, this has mostly been based on global aggregates of glacier extent. Differing opinions also exist about the best way to measure glacial change all over the world.  A recent study by Roe et…

  • Roundup: Snow Bacteria, Sting, and Glacier Awareness

    Roundup: Bacteria, Sting, and Glacier Awareness   Snow Bacteria in the Tibetan Plateau From INFONA: “Snow bacterial abundance and diversity at the Guoqu Glacier and the East Rongbuk Glacier located in the central and southern Tibetan Plateau were investigated using a 16S rRNA gene clone library and flow cytometry approach. Bacterial abundance was observed to…

  • Photo Friday: Mt. Baker Glaciers

    Washington is the second most-glaciated state in the United States, after Alaska. Mount Baker, located in the North Cascade Range, is an active stratovolcano that contains about 49 square kilometers of glaciers. The region is a popular skiing destination and the surrounding Skagit Valley provides a beautiful location from which to photograph glaciers. Chris Pribbernow…

  • Brittle Stars, Sea Urchins, and Starfish

    The increase of heat-trapping greenhouse gases in Earth’s atmosphere is warming the Antarctic Peninsula at a unprecedented rate. A recent study from Angulo-Preckler et al. in Continental Shelf Research explores whether significant decreases in sea ice and melting glaciers in the waters west of the Antarctic Peninsula favor some species of marine life and harm…

  • When Lava Hits Ice in Russia’s Far East

    The Kamchatka Peninsula in Far East Russia is an isolated region known for its glacier-volcano interactions that can lead to powerful natural disasters— and also, visually stunning images when lava impacts ice. One of these volcanoes, Sheveluch, has been erupting in recent weeks, creating local hazards. The volcano’s ash cloud, for one, threatens to disrupt air…
