Ice is a hazardous beauty, ephemeral in nature and, under the right conditions, capable of dominating landscapes. Earlier this year, while North America enjoyed an unusually mild winter, central and eastern Europe experienced brutal cold spells. The continent witnessed widespread freezing as cold air swept south from Siberia, claiming hundreds of lives, knocking out power supplies, and disrupting ...[Read More]

Imaggeo on Mondays: Burst
This photo won 2nd Prize at the 2012 General Assembly photo competition and, according to the photographer, Melissa S. Bukovsky, epitomises the idea that an expensive camera is not a necessity for taking great photos. “You just need to know how to use what you have. I travel with a point and shoot that fits in my back pocket,” she explains. Currently a Project Scientist at the National ...[Read More]

Imaggeo on Mondays: Traveling resource
An iceberg is formed when large pieces of ice break from snow-formed glaciers or ice shelves and float through the open oceans carried by wind and currents. They range in size and can be as large as over 75 m high and over 200 m wide, an important threat to unknowing ships. To that end, last month marked a century since the Titanic sank after colliding with an iceberg, killing over 1,500 passenger ...[Read More]

Imaggeo on Mondays: Hurricane season, from above
From space, planet Earth resembles a glassy blue marble, a term that was first used to describe a photograph of the Earth taken by the Apollo 17 crew on their way to the moon in 1972. Aside from providing stunning views of our planet, images of the Earth taken from above can also be used for meteorological observations. This beautiful photograph, taken by the Meteosat Second Generation (MSG) satel ...[Read More]

Imaggeo on Mondays: A rock and a hard place
Rocks within the Earth are constantly being subjected to forces that bend, twist, and fracture them, causing them to change shape and size. This process is known as deformation. Polyphase deformation occurs over time when rocks are affected, or stressed, by more than one phase of deformation. Geomorphologist Amirhossein Mojtahedzadeh captured this stunning scene whilst on field work. “This p ...[Read More]

Imaggeo on Mondays: On the edge of an ice crevasse
Glaciers are persistent bodies of ice at least 100,000 square metres in area and 50 metres thick. They are mostly found in the polar regions but also in mountain ranges, and represent the largest reservoir of freshwater on Earth. This photo was taken by Zervas Efthimios in August 2009, on the climb towards Lenin Peak in the Pamir mountains, Central Asia. “This crevasse appeared just before ...[Read More]

Imaggeo on Mondays: A mineral under the microscope
Epidote, an abundant rock-forming mineral found in metamorphic rocks, nearly always appears in green, although it may vary in shade and tone. Under a microscope of polarized light, however, it exhibits strong pleochroism, that is, it shows different colors when observed at different angles. The thin section (a laboratory preparation of a mineral or rock sample for use with a polarizing microscope) ...[Read More]

Imaggeo on Mondays: Green river
Thermokarsts occur when solid permafrost melts and soil gives way forming pitted, irregular lands surfaces. They are common in the Arctic, as well as the Himalayas and Swiss Alps. To study them, scientists trace the water using fluorescence dyes, temporarily creating water flows of exotic colours, like the bright green one in this Imaggeo photo. This photo was taken by Simon Gascoin, a researcher ...[Read More]

Imaggeo on Mondays: Quito and Cotopaxi
The sky is painted purple in this stunning evening photo taken near Quito, Ecuador. The country’s second most populous city is illuminated by artificial light, and Cotopaxi, an active volcano forming part of the Pacific Ring of Fire, looks out in the background. Located about 28 km south of Quito, Cotopaxi is the second highest summit in Ecuador (5,897 m) and features one of the few equatori ...[Read More]

Imaggeo on Mondays: Praia das Rodas, Spain
Often listed as one of the most beautiful beaches in the world, Praia das Rodas is located on the Isla do Faro, part of the three-island Cíes archipelago within the Atlantic Islands of Galicia National Park. The beach faces eastwards, towards Vigo and the Galician coast of northwestern Spain, its accumulation of sand forming a land-bridge between two islands during low tide. All three islands are ...[Read More]
