  • Roundup: Lakes Grow, Fish Feed, Pruitt Seethes

    Marine-Terminating Glaciers a Boon for Fish From Global Change Biology: “Accelerated mass loss from the Greenland ice sheet leads to glacier retreat and an increasing input of glacial meltwater to the fjords and coastal waters around Greenland. These high latitude ecosystems are highly productive and sustain important fisheries, yet it remains uncertain how they will…

  • Photo Friday: Island Glaciers of the Canadian Arctic

    Outside of Greenland, a quarter of the Arctic’s ice lies in Canada, much of it covering the Queen Elizabeth Islands. A recent paper in Environmental Research Letters found that, during the decade between 2005 and 2015, surface melt from the ice caps and glaciers of the Queen Elizabeth Islands increased by a staggering 900 percent,…

  • Lessons in Collaboration from the Tanana Watershed

    This story is Part I of a two-part series on the Tanana River Watershed. What do a St. Patty’s Day party and a sub-Arctic river have in common? An abundance of green dye, which acts as a festive element for the first and a scientific tool for the second. A group of Alaskan scientists used…

  • Narwhals in Scoresby Sound

    A version of this post originally appeared on narwhals2017.com. It has been lightly edited and republished with permission by the researchers of the Greenland Institute of Natural Resources (Pinngortitaleriffik). In 2010, Mads Peter Heide-Jørgensen and his colleague Hans Christian Schmidt discovered that Hjørnedal in Scoresby Sound in the Greenland Sea was an ideal place for the live capturing of…

  • Life, Death and Predation on the Greenland Ice Sheet

    Mention the Greenland Ice Sheet, and chances are that you conjure up the image of a barren, white wilderness, dominated by ice and devoid of life. In fact, the ice sheet and its coastal outlet glaciers support thousands of small pools that teem with bacteria and animals. “A world of microbes exists in these tiny,…

  • Roundup: Dust, Collapse, and Fire

    Dust Distribution in East Asia From Journal of Meteorological Research: “East Asian dust (EAD) exerts considerable impacts on the energy balance and climate/climate change of the earth system through its influence on solar and terrestrial radiation, cloud properties, and precipitation efficiency. Providing an accurate description of the life cycle and climate effects of EAD is…

  • Future Unwritten: Antarctic Sea Pens’ Secrets to Success

    On the seafloor, beneath the cold, dark waters surrounding Antarctica, life blooms. Sea stars make their glacially-slow journeys along rocks, sponges rhythmically pulse water through their internal cavities, and one particular coral, the delicate sea pen Malacobelemnon daytoni, flourishes. Sea pens are colonial, meaning that many individuals work together as a whole, each conducting a…

  • Wildfires in Peru Could Increase Glacial Melt

    A recent study by John All et al., “Fire Response to Local Climate Variability,” investigates whether or not human interference in the fire regime of Huascarán National Park in Peru was the primary cause of an increase in fire activity in the park. The fire activity, whether caused by humans or climate variability, was poorly…

  • 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…
