  • Photo Friday: The Glacial Alaska Range

    The Alaska Range is a narrow, 700-kilometer mountain range defined by rugged peaks and large U-shaped glacial valleys. The range lies in the southeast corridor of Alaska and is home to Denali, the tallest peak in North America. The Alaska range is part of the American Cordillera and possesses peaks only trumped by those in…

  • A New Technique to Study Seals Habitats in Alaska

    There are numerous harbor seals (Phoca vitulina) living in tidewater glacier fjords in Alaska. Harbor seals are covered with short, stiff, bristle-like hair. They reach five to six feet (1.7-1.9 m) in length and weigh up to 300 pounds (140 kg). Tidewater glaciers calve icebergs into the marine environment, which then serve as pupping and molting habitat for harbor seals…

  • Photo Friday: Benchmark Glaciers in the USA

    Glaciers contain about three quarters of the world’s fresh water and cover about 75,000 square kilometers of the U.S. The United States Geological Service (USGS) has been running the Benchmark Glacier program since the late 1950s to track glacier mass balance. Repeat measurements at four selected sites are used in conjunction with local meteorological and…

  • How Mendenhall Glacier Teaches About Climate Change

    Mendenhall Glacier (Source: Cameron Cowles). Visiting Mendenhall Glacier near Juneau, Alaska is a memorable experience for about 575,000 visitors each year. A top attraction, the glacier stretches 13 miles across the Juneau Ice Field, terminating on the far side of Mendenhall Lake. Surrounded by 38 other glacial remnants of the last ice age, it remains one…

  • Alaska Filmmaker Mike Loso Speaks about Glaciers

    The short firm “Glaciers – Why Should We Care?” is currently being shown as part of International Polar Week. This event, running from 19 to 25 September 2016, is designed to promote polar science and education around the world, and includes a five-day film festival. It is sponsored by the Association of Polar Early Career Scientists,…

  • Wildfires Melt Glaciers From a Distance

    Scientists have begun to trace a link between climate change, an increased number of wildfires and glacier melting.  Particles emitted by wildfires and then deposited on glaciers are thought to darken the ice’s surface, and may lead to more rapid melting. Natalie Kehrwald, a geologist from the United States Geological Survey (USGS), is currently studying…

  • Photo Friday: The Glaciers of Denali National Park

    Denali National Park spans a vast six million acres in central Alaska, and contains the tallest mountain on the continent that gives the park its namesake: Denali, formerly known as Mount McKinley. The summit reaches over 20,000 feet above sea level, and is one of the most isolated mountain peaks in the world—following only Mount…

    Roundup: Studying and Dancing to Melting Glaciers

    Dancing to the tune of a melting glacier: CoMotion tackles climate change From Missoulian:    “If someone suggested you watch artists perform an hour-long dance about climate change, you might shoot them your best ‘have-you-lost-your-mind’ look. But your curiosity level might be raised, too. When Karen Kaufmann’s phone rang in February 2015 and the caller asked her…

  • Survival is just the tip of the iceberg in Blair Braverman’s memoir on Arctic life
