  • Roundup: Icebergs, Mobile Toxins, Festive Algae

    Iceberg Ahead! A New Study Finds Way to Avert Disaster “When performing offshore operations in the Arctic, there are several challenges. One of those challenges is the threat of icebergs on offshore structures and vessels. Icebergs can exert extremely high loads on vessels, offshore platforms, and seabed installations.” Find out how the team is proposing…

  • Roundup: Gloomy Glaciologist, Icy Blasts, and New Models

    Glaciologist Causes Chills with Not So Icy Predictions “How does being the one to look at the grim facts of climate change most intimately, day in and day out, affect a person? Is Box representative of all of the scientists most directly involved in this defining issue of the new century? How are they being…

    The Question of Black Carbon

    Black carbon has only recently emerged as a known major contributor to climate change, especially for the Arctic. Formed by the incomplete combustion of fossil fuels, biofuels, and biomass, black carbon absorbs light more strongly than any other particulate matter, especially when deposited onto glaciers and snow cover. Here, it lowers their reflectivity, thereby absorbing…

  • Glacier Past Unveiled Through Sediments

    Researchers have long used preserved sediment layers in glaciers as time records to understand the climate of the past. But now, researchers, publishing in Quaternary Science Reviews, have used lake sediments in glacier-fed Lake Hajeren in Svalbard to recreate glacier variability during the Holocene period. The sediments, which were deposited over millennia, have been undisturbed, allowing researchers to…

  • Photo Friday: A Snapshot of Svalbard

    Svalbard is a Norwegian archipelago tucked in between Norway and the North Pole. Especially known for its views of the Northern Lights and its summer “midnight sun,” in which sunlight graces the archipelago 24 hours a day, Svalbard is also known for its glaciers, which cover around 60 percent of Svalbard’s land area. Project Pressure,…

  • The Microscopic Life of Glaciers

    Though it can be hard to imagine that cold, barren-looking glaciers are conducive to life, glaciers are actually teeming with organisms. Glacier surfaces are filled with cylindrical holes called cyroconite holes, in which melt water accumulates and micro-algae and cyanobacteria  thrive. Now, a new study published in Biogeosciences has taken a closer look at these complex ecosystems…
