The Arctic has undergone some of the most rapid transformations over the past 50 years, with global implications for the Earth’s climate. A dramatic indicator of Arctic climate change is the shrinking summer sea ice cover. Recently Arctic sea ice loss has accelerated with the ten lowest minima sea ice extents (SIE) all occurring in the last ten years, and the Arctic is now expected to become ice-free during summer at some point this century.

The Campi Flegrei volcanic complex, in southern Italy, is showing its first signs of unrest for more than 400 years. The Deep Drilling Project promises exciting new information about the state of the volcano. A team from the UCL Hazard Centre is working with colleagues at the Vesuvius Observatory to discover where and when another eruption can be expected. As team leader Dr Christopher Kilburn explains: “We are studying Campi Flegrei, not only to advance science, but also to protect the 300,000 people living across the volcano.” More...
The Ainsa Deepwater Channel Project, Spanish Pyrenees
An Integrated Outcrop Study: Project Manager: Professor Kevin T. Pickering
Introduction to the Ainsa Channel System
The Ainsa Channel System, south-central Pyrenees, occurs in the oldest part of the Campodarbe Group, and it is of Upper Eocene age. The Ainsa Channel Complex is per- haps the most famous of the submarine channel outcrops within Western Europe. The Ainsa channels consist of two principal channel complexes (Ainsa I and Ainsa II) which are separated by thin- and very thin-bedded sandy turbidites and marls. The Ainsa I Channel Complex is an example of an erosional-depositional system. The Ainsa II Chan- nel Complex contains significant erosional cut-downs, with infill of essentially non- erosive sandy facies. The channel dimensions are at a seismic scale.
