Imaggeo On Monday: Under the sea, in the deep, where fire meets water and life emerges III

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]

Imaggeo On Monday: Geoscientific selfie at the Dead Sea

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]

Celebrating the 100th birth anniversary of Marie Tharp: Seafloor mapping and ocean plate tectonics

Celebrating the 100th birth anniversary of Marie Tharp: Seafloor mapping and ocean plate tectonics

The seafloor mapping pioneered by Marie Tharp, an American geologist and cartographer, though originally underappreciated, ended up playing a key role in the acceptance of the theory of plate tectonics. This week the EGU is highlighting Tharp’s groundbreaking contributions by hosting both a press conference and a session in her honour at the Union’s virtual annual meeting, Sharing Geoscience Onlin ...[Read More]

Winners of the EGU Best Blog Posts of 2019 Competition

2019 was a brilliant year for our blogging network here at EGU. Across the EGU’s official blog, GeoLog, as well as the network and division blogs there were so many interesting, educational and just downright entertaining posts this year it was hard to get the blog editors to choose their favourites! Nevertheless in December, to celebrate the excellent display of science writing across the network ...[Read More]
