Patagonia, the region in southernmost tip of South America, is as diverse as it is vast. Divided by the Andes, the arid steppes, grasslands and deserts of Argentina give way to the temperate rainforests, fjords and glaciers of Chile. Also on the Chilean side are rolling hills and valleys of marshy topography: Patagonia’s bogs. Today, Klaus-Holger Knorr, a researcher at the University of Münster’s ...[Read More]

Imaggeo on Mondays: Measuring the wind direction
Remote, rugged, raw and beautiful beyond measure, the island of South Georgia rises from the wild waters of the South Atlantic, 1300 km south east of the Falkland Islands. The Allardyce Range rises imposingly, south of Cumberland Bay, dominating the central part of the island. At its highest, it towers 2935 m (Mount Paget) above the surrounding landscape. In the region of 150 glaciers carve their ...[Read More]

Record-setting forest fires in 2017 – what is to blame?
Forest fires have once again seized the public consciousness in both Europe and North America. Extreme drought and temperatures contributed to a tinderbox in many forests, and have led to deadly fires across Europe and record-breaking, highly disruptive fires in the USA and Canada, from where I’m currently writing. A simple way to understand fire is by thinking about the fire triangle – the three ...[Read More]
GeoPolicy: IPCC decides on fresh approach for next major report
This month’s GeoPolicy post is a guest post from Sarah Connors, a Science Officer in the Intergovernmental Panel on Climate Change (IPCC) Working Group 1 Technical Support Unit (and former EGU Science Policy Officer). The IPCC is starting its sixth cycle, in which hundreds of scientists take stock of the world’s climate change knowledge by assessing the current scientific literature and then summa ...[Read More]
Imaggeo on Mondays: Isolated atoll
Covering a total area of 298 km², the idylic natural atolls and reefs of the Maldives stretch across the Indian Ocean. The tropical nation is famous for it’s crystal clear waters and picture perfect white sand beaches, but how did the 26 ring-shaped atolls and over 1000 coral islands form? Coral reefs commonly form immediately around an island, creating a fringe which projects seawards from the sh ...[Read More]
GeoSciences Column: Catch of the day – what seabirds can tell us about the marine environment
Off the coast of Germany, a male northern gannet (for ease, we’ll call him Pete) soars above the cold waters of the North Sea. He’s on the hunt for a shoal of fish. Some 40km due south east, Pete’s mate and chick await, patiently, for him to return to the nest with a belly full of food. Glints of silver just below the waves; the fish have arrived. Pete readies himself. Body rigid, wings tucked in ...[Read More]
Imaggeo on Mondays: A prehistoric forest
This stunning vista encompasses the south-western wilderness of Tasmania as seen from the Tahune air walk 60 m above the Huon river valley. In front lies the beginning of a huge UNESCO World Heritage Site, covering almost a fourth of the area of Tasmania. The site mostly consists of a pristine, temperate rainforest of Gondwanan origin that is home to the tallest flowering trees in the world; Eucal ...[Read More]
Is it an earthquake, a nuclear test or a hurricane? How seismometers help us understand the world we live in
Although traditionally used to study earthquakes, like today’s M 8.1 in Mexico, seismometers have now become so sophisticated they are able to detect the slightest ground movements; whether they come from deep within the bowels of the planet or are triggered by events at the surface. But how, exactly, do earthquake scientists decipher the signals picked up by seismometers across the world? And mo ...[Read More]
Imaggeo on Mondays: Viñales Valley
From last week’s unusual desert landscape to this week’s lush valley in Cuba… The picture shows the Vinales Valley, a karstic depression with mogotes in western Cuba. Karst is the general term for landscapes formed when limestone is disolved by carbonic acid, in rain water. This leads, in particular, to the formation of an underground network of caves and rivers. In the tropics, ...[Read More]
