Imaggeo on Mondays: A voyage through scales – The Badlands National Park, South Dakota.

Laura Roberts-Artal June 22, 2015

Layer upon layer of sand, clay and silt, cemented together over time to form the sedimentary units of the Badlands National Park in South Dakota, USA. The sediments, delivered by rivers and streams that criss-crossed the landscape, accumulated over a period of millions of years, ranging from the late Cretaceous Period (67 to 75 million years ago) throughout to the Oligocene Epoch (26 to 34 million ...[Read More]

The planet is set to encounter a record-level amount of floods and droughts by 2050 – researchers recently announced at the European Geosciences Union’s General Assembly in Vienna. Nikita Marwaha shares their predictions on the impact that climate change will have on these extreme weather conditions. In a study by the Joint Research Centre (JRS) – the European Commission’s in-house science service ...[Read More]

Imaggeo on Mondays: Finger Rock

Laura Roberts-Artal April 27, 2015

Standing proud amongst the calm waters of Golovnina Bay is ‘The Devil’s Finger’, a sea stack composed of volcanic sediments. Located on the Pacific coast of Kunashir Island -which is controlled by Russia but claimed by Japan – the stack is testament to the volcanic nature of the region. The island itself is formed of four active volcanoes which are joined together by low-lying geothermally active ...[Read More]

Imaggeo on Mondays: Earthquake Lake

Laura Roberts-Artal April 20, 2015

Despite its alluring turquoise waters and rugged mountain backdrop the story behind this beautiful lake is rather more troubling. In today’s Imaggeo on Mondays, the first post since our short break from the traditional format during the General Assembly, Alexander Osadchiev writes about the shaky origins of Sarez Lake. Lake Sarez is situated in Tajikistan, deep in the Pamir Mountains. In 1911 a lo ...[Read More]

Imaggeo on Mondays: Drumlins Clew Bay

Laura Roberts-Artal March 30, 2015

During ice ages landscapes are sculpted by the power of advancing glaciers. From rock scratches, to changing mountains and the formation of corries, cirques and aretes, through to the formation of valleys and fjords, the effects of past glaciations are evident across the northern hemisphere landscape. Perhaps not so familiar, drumlin fields are also vestiges of the erosive power of ancient ice she ...[Read More]
