In the shadow of the Santos oil and gas processing plant and export terminal lies the only place in the world where cuttlefish come together by the tens of thousands to mate every winter. The unique geology of the area, with a seafloor composed of bedrock and tabular quartzite blocks, makes for an ideal egg-laying habitat, and thus is an attractive breeding ground for the Australian Giant Cuttlefi ...[Read More]

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]

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]
