The Earth’s magnetic field extends from the core of the planet, right out to space. It is an invisible, butterfly-like, shield which protects us against the harmful particles ejected by solar flares. In addition, it guards us from atmospheric erosion and water loss caused by solar wind. But how do scientists study the Earth’s magnetic field when it can’t be see? Much of what is known results from ...[Read More]

The Gulf of Corinth, in southern Greece, separates the Peloponnese peninsula from the continental mainland. The structural geology of the region is complex, largely defined by the subduction of the African Plate below the Eurasian Plate (a little to the south). The Gulf itself is an active extensional marine basin, i.e., one that is pulling open and where sediments accumulate. Sedimentary basins r ...[Read More]

Beautiful, eyrie, the land where fire meets ice: Iceland. An Earth scientist’ dream, complete with lava, volcanoes, earthquakes, impossible landscapes, ice, snow, the ocean…Iceland ...[Read More]
