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]

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]

GeoSciences Column: When could humans last walk, on land, between Asia & America?

Though now submerged under 53 m of ocean waters, there once was a land bridge which connected North America with Asia, allowing the passage of species, including early humans, between the two continents. A new study, published in the EGU’s open access journal Climate of the Past, explores when the land bridge was last inundated, cutting off the link between the two landmasses. The Bering Strait, a ...[Read More]
