Imaggeo On Monday: Studying shell morphodynamics to improve climate models

Profile of a specimen of Arctica islandica, one of the longest lived marine bivalves known, undergoing a 3D scan. Their longevity is exploited for reconstruction of climate patterns in the North Atlantic. However, mathematical models of their morphodynamics are necessary to account for bias induced by their asymmetric growth (“morphodynamics” is the study of how an organisms’ gro ...[Read More]

Imaggeo On Monday: Catch the wave hitting on the rocks

A wave is caught on camera when it hits the rocks on Tung Ping Chau, an offshore island in the northeastern corner of Hong Kong. Tung Ping Chau is unique island in Hong Kong that is mainly made up of sedimentary rock. Weathering and erosion have great impacts on forming the current landscape and geologic features such as wave-cut platforms and sea cliffs on Tung Ping Chau.   Description by An ...[Read More]

Imaggeo On Monday: Water Force

A force is a push or pull upon an object resulting from the object’s interaction with another object. This image shows the most magnificent force in nature; water, interacting with an inclined rock formation, with a backdrop of the magnificent landscapes of Canada.   Description by Daniela Lobianco, after the description on imaggeo.egu.eu.   Imaggeo is the EGU’s online open access ...[Read More]

Imaggeo On Monday: Yardangs in the Gobi desert

Seeing the Yardang rock formations during sunset was a surreal experience. While they seem to have be standing in a sea of water that formed them, the fluid dynamics that actually lead to their existence is the result of wind abrasion by dust and sand and the removal of loose material by wind turbulence. The air flow and resulting pattern of erosion and the distribution of rocks determines their s ...[Read More]
