Figuring out what the climate was like, and how it changed, throughout Earth’s history is like trying to complete a 1000 piece puzzle. Except that scientists usually don’t have all the nuggets and building a comprehensive picture relies on a multidisciplinary approach in order to fill in the blanks. This is particularly true during the …[Read More]

Imaggeo on Mondays: A sunrise over Kelimutu’s three-colour lakes
Volcanoes are undeniably home to some of the most beautiful landscapes on Earth. It doesn’t take much imagination to picture slopes of exceedingly fertile mineral rich soils, covered in lush vegetation; high peaks punching through cloud cover offering stunning vistas and bubbling pools of geothermally warmed waters were one can soak ones worries away. What …[Read More]
Imaggeo on Mondays: Storm on the Rock
This is a photograph of Uluru, in the Northern Territory of Australia, on a hot and humid summer afternoon. As lightning flashed about, torrential rains swept across the landscape and silver rivulets of water began to rush down the sides of the mountain. Uluru is made of red-coloured Proterozoic arkosic sandstones, a coarse grained lithology …[Read More]
Imaggeo on Mondays: Moving images – Photo Contest 2016
Since 2010, the European Geosciences Union (EGU) has been holding an annual photo competition and exhibit in association with its General Assembly and with Imaggeo – the EGU’s open access image repository. In addition to the still photographs, imaggeo also accepts moving images – short videos – which are also a part of the annual …[Read More]
Imaggeo on Mondays: Half dome at sunset
Yosemite’s Half Dome stands, majestic, over a granite dominated terrain in the Yosemite Valley area; one of the most beautiful landscapes in northern America, and arguably, the world – it is also an Earth scientist’ playground. Stamped into the west slope of the Sierra Nevada range, the Yosemite Valley is a collection of lush forests, …[Read More]
Imaggeo on Mondays: Earth Wave
Take a stroll along the norther beaches of the French Channel Coast, some kilometers east from the entrance of the Channel Tunnel, and you’ll encounter an imposing cliff of soft, sandy composition which dominates the landscape. On close inspection, the sediments which make up the Quaternary aged deposits of the Sangatte Cliff, are beautiful, revealing …[Read More]
When mountains collapse…
Jane Qiu, a grantee of the Pulitzer Center on Crisis Reporting, took to quake-stricken Nepal last month — venturing into landslide-riddled terrains and shadowing scientists studying what makes slopes more susceptible to failure after an earthquake. The journey proved to be more perilous than she had expected. What would it be like to lose all …[Read More]
Imaggeo on Mondays: recreating geological processes in the lab
Many of the processes which take place on Earth happen over very long time scales, certainly when compared to the life span of a person. The same is true for geographical scale. Many of the processes which dominate how our planet behaves are difficult to visualise given the vast distances (and depths) over which they …[Read More]
Imaggeo on Mondays: Through the hole
The Gunung Mulu National Park is an area so geologically remarkable and home to such incredibly diverse fauna and flora it has been declared a World Heritage Area. Located on the island of Borneo, the park is famous for its over 100 different palm species and 3500 other plant types. Geologically speaking, a trip though …[Read More]
Imaggeo on Mondays: Dune ridge perspective
Imagine taking a hike over soft, ever shifting sands. This is exactly what Martina Klose, a researcher at USDA, did when she captured this beautiful photograph. While most of us will likely think of deserts as inhospitable and static landscapes, they can tell us much about dune forming processes, as Martina explains in today’s blog …[Read More]
