650 metres below the chilly waves of the North Atlantic Arctic Ocean, equidistant between Norway, Iceland and Greenland, are the Jan Mayen Vent Fields. Home to a series of hydrothermal vents strung along a set of normal faults and fissures that run parallel to the seafloor ridge, this is a strange and fascinating place. Hydrothermal vents are places where tectonic activity provides a way for the h ...[Read More]

This is an aerial image taken from a balloon at around 150m height, at the eastern shoreline of the Dead Sea. Such “selfies” are scientifically valuable, providing important data that help researchers to analyze the morphology of the retreating lake and investigate associated hazards like sinkholes, subsidence and landslides. The older shorelines, visible as lines on the shore stand fo ...[Read More]

The badlands at the Zabriskie Point (Death Valley, California, USA) rest upon a mudstone foundation. In the prehistoric lakes of Death Valley, fine grained sediments were deposited to form soft rocks. The clay minerals in the mudstone are shaped like tiny plates, which helps create the layers. The combination of the almost impermeable mudstone and Death Valley’s low rainfall makes plant grow ...[Read More]
