When he is not researching in the space sciences, Ioannis Daglis, the director of the Institute for Space Applications and Remote Sensing at the National Observatory of Athens in Greece, is often out with his camera. This picture of sea waves slamming cliff rocks in the Aegean Sea is a beautiful example of his artistic work, and one that shows some science too.

“I took this photo at Vitali Bay in the island of Andros in the Greek Cyclades during a summer vacation in August 2007. It shows a cliff made irregular by wave erosion, tectonic activity or both. It consists mainly of metamorphic rocks such as schists, phyllites and marbles. These are typical geologic formations that constitute 75% of the total coastline of the island since Andros is mainly covered by metamorphic formations,” Daglis explained.

The Cyclades is a geologically rich group of some 220 islands. The dormant volcano of Milos, the famous Santorini caldera, and the hot springs in Kythnos are examples of geological sites worth a visit.

Daglis’ geosciences-related photographs, taken in Greece and elsewhere, are featured on Imaggeo.

Imaggeo is the online open access geosciences image repository of the European Geosciences Union. Every geoscientist who is an amateur photographer (but also other people) can submit their images to this repository. Being open access, it can be used by scientists for their presentations or publications as well as by the press. If you submit your images to imaggeo, you retain full rights of use, since they are licenced and distributed by EGU under a Creative Commons licence.
