Imaggeo on Mondays: Travertine takeover

This week’s Imaggeo on Mondays is brought to you by Olivier Galland, who took this photo during an incredible outreach adventure in the Andes…  The image displays the spectacular Puente del Inca (The Inca Bridge) hot springs, in the Argentinian Andes of the Mendoza province, along the Vacas River, close to the foot of Cerro Aconcagua. When the mineral-rich, sulphurous waters reach the surface, the ...[Read More]

Imaggeo on Mondays: Eddy covariance

This week’s Imaggeo on Mondays is brought to you by Jean-Daniel Paris, a meteorologist from the Climate and Environmental Sciences Laboratory (LSCE), France. He describes how new techniques like eddy covariance tell us about the flux of greenhouse gas emissions to the atmosphere…  This picture was taken during a visit to the Hyytiälä research station in Finland in June 2010. This station runs flux ...[Read More]

Imaggeo on Mondays: Great faults and faultless geotourism

Road cuttings provide a great window into the wonders of what’s beneath the Earth’s surface. In this week’s Imaggeo on Mondays Bahram Sadry takes us through a beautiful fault between Tabriz and Tehran, Iran… These incredible rock outcroppings along Zanjan-Tabriz highway (the northwest of Iran), are unlike any other outcrop in the world. They are a group of faults and fractures, brecciation and gra ...[Read More]

Imaggeo on Mondays: Surface spirals

This week’s Imaggeo on Mondays is no ordinary image; it’s a snapshot of surface ocean speeds and the extent of ice cover in the North Atlantic. It was produced using a high resolution model of ocean eddies – high resolution here means that details are simplified into grids 3 km across, or one 20th of a degree. Three kilometres may sound like a pretty large area, but in oceanographic modelling, thi ...[Read More]
