Did you know that the shape of coastlines is determined by the angle at which waves crash against the shoreline. It has long been thought that fluctuations in the wave incidence angle are rapidly felt by coastlines, which change the shapes of their shores quickly in response to shifting wave patterns. Or do they? Researchers at the British Geological Survey, Duke University (USA) and Woods Hole Oc ...[Read More]

This week’s Imaggeo on Monday’s post, captured by Maksim Cherviakov, shows students from Saratov National Research University practicing a method to measure lake ice thickness. The students are using an ice auger to manually burrow through the ice. Afterwards, the ice depth is recorded using a tape measure. “We measure ice thickness every year on the lakes located in the floodplain of the Vo ...[Read More]
