Roundup: A Glacier Bus, Andean Rivers, and Ice-Cored Moraines

The Glacier Bus Turning Heads

From Iceland Monitor: “Glacier bus Sleipnir, named after Odin’s eight-legged-horse in Norse mythology, is the largest such truck in the world. It features eight wheels and is currently being tested on Langjökull Glacier where it passes with flying colors. It features comfortable leather seats inside for passengers with views to both sides of the vehicle and through the roof. The vehicle cost around 70 million ISK to make and it can cross glacial crevasses measuring up to three meters.”

Determining Distribution of Insects in Andean Rivers

From Ecohydrology: “This research was conducted in the high-Andean basin of the Zhurucay River in southern Ecuador. In 4 river reaches, 19 sampling campaigns were conducted per reach spread over a period of 35 months. The biotic samples were selected in the periods with greatest flow stability… In conclusion, although macroinvertebrates are currently employed in water quality studies, riparian vegetation and hydromorphological factors are determinant for their communities in pristine Andean rivers. Such factors are therefore crucial in the study of environmental flows and the assessment of the ecological integrity.”

Interpreting Exposure Ages from Ice-Cored Moraines

From Journal of Quaternary Science: “Be dating of moraines has greatly improved our ability to constrain the timing of past glaciations and thus past cold events… Here we present 28 new Be ages from ice-cored Neoglacial moraines on Baffin Island, Arctic Canada, and explore the processes at play in moraine formation and evolution through field observations and a numerical debris-covered glacier model… Three Baffin Island moraines yield Be ages suggesting formation at 5.2, 4.6 and 3.5 ka, respectively, adding to a growing body of evidence for significant summer cooling millennia before the Little Ice Age.”
