Imaggeo on Mondays: Sundogs in Alaska
The northern part of the US state of Alaska is tundra, an area where freezing-cold temperatures hinder tree growth. The result is an unobstructed view of the rising or setting sun that allows photographers to beautifully capture our star. It was in this treeless area that Yongwon Kim, a researcher from the University of Alaska Fairbanks, took this stunning photo of an eerie sun in 2010.Sundogs, at ...[Read More]

Imaggeo on Mondays: Frozen river meets the sea
This image shows part of the frozen delta of the Siberian River Lena. Thomas Ernsdorf, a researcher at the Department of Environmental Meteorology, University of Trier in Germany, took this photo during a Russian-German expedition to the Laptev Sea, the largest ice factory of the Arctic Ocean, in April 2008. “The main goal of the expedition was to investigate the polynia (large open water and thin ...[Read More]

Geosciences Column: Why are jet streams not good wind energy sources?
Commercial airlines know jet streams well. Planes often hitch a ride on these strong, high-altitude atmospheric winds, which blow from west to east, to fly faster, and they are the reason why long-haul easterly flights (such as those between the US and Europe) are quicker than the corresponding westerly journeys. Scientists are also familiar with these fierce and persistent winds, which occur at a ...[Read More]

Geosciences Column: Iceland spar, or how Vikings used sunstones to navigate
Nowadays, we can rely on GPS receivers or magnetic compasses to tell us how to reach our destination. Some 1000 years ago, Vikings had none of these advanced navigation tools. Yet, they successfully sailed from Scandinavia to America in near-polar regions where it can be hard to use the Sun and the stars as a compass. Clouds or fog and the long twilights characteristic of polar summers complicate ...[Read More]
