Imaggeo On Monday: Iceberg A-81, Brunt Ice Shelf, Antarctica

Imaggeo On Monday: Iceberg A-81, Brunt Ice Shelf, Antarctica

Information from a British Antarctic Survey Press Release. A huge iceberg (1550 km²), almost the size of Greater London, has broken off the 150m thick Brunt Ice Shelf. It calved after cracks that have been developing naturally over the last few years extended across the entire ice shelf, causing the new iceberg to break free. This occurred on Sunday 22 January between 19.00 and 20.00 UTC during a ...[Read More]

Imaggeo On Monday: Eyjafjallajökull – hot and cold

Active volcano Eyjafjallajökull is covered by 80 square kilometres of glaciers. Quite often one can feel the warmth from the red igneous rocks that protrude from the ice cap. The volcano is known for the eruption in April 2010, which released ash clouds so large that in some areas they turned daylight into darkness. Many flights in Europe were cancelled. A significant part of the glacier melted in ...[Read More]

Imaggeo On Monday: High amplitude ‘V-shaped’ kink fold with axial plane cleavage

The Himalayan-Tibetan orogeny has been considered the youngest collisional fold belt in the Earth and a classic example of intercontinental collision orogeny. It is comprised of different litho-tectonic units manifested by normal/thrust faults and suture zones (Valdiya, K.S., 1977). The Himalayan region has experienced multifaced deformation, spectacular rock assemblages with high-pressure-tempera ...[Read More]

Imaggeo On Monday: Different structures for coastal management

  Different structures for coastal management at Spiekeroog, Germany. The structures include a groyne and a revetment. Groynes are cross-shore structures, linearly ordered from the shoreline and into the sea. Typically made of rock or wood, groynes are built to limit the longshore transport and loss of shore material like sand or shingle. The build-up shore material captured by the groynes re ...[Read More]

Imaggeo On Monday: The movement of the tides

Tides are very long-period waves characterized by the rise and fall of sea levels. This phenomenon occurs in response to forces exerted jointly by the moon and sun, generated in the ocean, and propagating toward the coast. Tides can be divided into two main types: low tide and high tide. High tide occurs when sea water rises above the mean level while low tide occurs when sea water falls below the ...[Read More]
