Imaggeo On Monday: Comb through the mysteries of Comb Ridge, Utah

Scientists have combed through the mysteries offered by this ridge for a long time. This is an aerial image of the linear north-south ridge in South-Eastern Utah. First mapped by modern geoscientists in the late 19th century, the ridge is home to numerous Puebloan cliff dwellings and petroglyphs. It is a National Natural landmark and home to the only fossils of a mammal-sized cynodonts (tritylodon ...[Read More]

Imaggeo On Monday: Scary sea ice drilling in the antarctic darkness!

Imaggeo On Monday: Scary sea ice drilling in the antarctic darkness!

This picture was taken from the N.B. Palmer ice breaker during the PIPERS expedition in the austral winter of 2017. Two researchers and a marine technician were drilling cores in the sea ice of the Ross Sea. The ice was too thin and started to crack (see the fault in the background), so the team had to drill from the basket.

Imaggeo On Monday: Drought – a prerequisite for hazardous flash floods

Imaggeo On Monday: Drought – a prerequisite for hazardous flash floods

The drying out of the soil leads to the hazard of flash floods in the wadis of the Dead Sea Valley during sparse but strong rain events. During longer precipitation-free periods and extreme low relative humidity, driven by mesoscale wind, the soil crust ultimately tends to break into piece.

Imaggeo On Monday: Plume of steam rising from the crater of Mount Erebus, Antarctica

Plume rising from Mount Erebus on a rare calm day. This 3794 m high volcano is the most active in Antarctica and close to the American base at McMurdo.
