Geosciences Column: Do coastlines have memories?

do coastlines have memories

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]

Imaggeo on Mondays: Tones of sand

Tones of Sand

With rocks dating as far back as the Precambrian, mountain building events, violent volcanic eruptions and being covered, on and off, by shallow seas, Death Valley’s geological history is long and complex. Back in the Cenozoic (65 to 30 million years ago), following a turbulent period which saw the eruption of volcanoes (which in time would form the Sierra Nevada of California) and regional uplift ...[Read More]

Shaking on Christmas Day: what we know about the 7.6 M Chile earthquake

Chile, Chiloe earthquake

While the majority of us were midway through our Christmas Day celebrations, a powerful 7.6 M earthquake struck off the western coast of the Chile. Natural hazards are not bound by time, location or festivities; an earthquake can happen at any time in any place, regardless of the significance of the day. As a result, in this earthquake prone region, raising awareness of the risk posed by natural h ...[Read More]

Limits to global groundwater use

Limits to global groundwater use

Post by WaterUnderground contributor Inge de Graaf. Inge is a postdoc fellow at Colorado School of Mines, in the USA. Groundwater is the world’s most important source of freshwater. It supplies 2 billion people with drinking water and is used for irrigation of the largest share of the world’s food supply. However, in many regions around the world, groundwater reserves are depleting as the re ...[Read More]

A water ocean inside Saturn’s moon Dione

A water ocean inside Saturn’s moon Dione

Deep inside Saturn’s moon Dione lies a global ocean of liquid water, according to scientists of the Royal Observatory of Belgium. Such discovery places Dione as the third Saturn’s moon, beside Enceladus and Titan, to have a subsurface ocean. Previous models of planet interior, based on gravity and shape data of Cassini, predicted no ocean at all for Dione and a very thick ice crust for ...[Read More]

Imaggeo on Mondays: Ice drilling

Ice drilling in Saratov

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]
