Geology has shaped the rugged landscape of the Isle of Skye – the largest island of Scotland’s Inner Hebrides archipelago. From the very old Precambrian rocks (approximately 2.8 billion years old) in the south of the island, through to the mighty glaciers which covered much of Scotland as recently as 14,700 years ago, the modestly-sized island provides a snap-shot through Earth’s dynamic his ...[Read More]

GeoPolicy: COP23 – key updates and outcomes
What is COP23? Anthropogenic climate change is threatening life on this planet as we know it. It’s a global issue… and not one that is easily solved. The Conference of the Parties (COP) provides world leaders, policy workers, scientists and industry leaders with the space to share ideas and decide on how to tackle climate change and generate global transformative change. COP23 will predominantly f ...[Read More]
Imaggeo on Mondays: Bird’s eye view of Trebecchi Lakes
Among many other environmental impacts, human activities have introduced a range of animal and plant species to areas where they do not naturally belong. The introduction of alien species, as these translocated taxa are known, has wide ranging implications for native biota, ecosystem functioning, human health and the economy. Research published earlier this year found that during the last 200 year ...[Read More]
GeoSciences Column: The dirty business of shipping goods by sea
Shipping goods across the oceans is cost-effective and super-efficient; that’s why over 80% of world trade is carried by sea (according to the International Maritime Organisation). But the shipping industry also contributes significant amounts of air pollutants to marine and coastal environments. A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]
Imaggeo on Mondays: Of ancient winds and sands
Snippets of our planet’s ancient past are frozen in rocks around the world. By studying the information locked in formations across the globe, geoscientist unpick the history of Earth. Though the layers in today’s featured image may seem abstract to the untrained eye, Elizaveta Kovaleva (a researcher at the University of the Free State in South Africa) describes how they reveal the secrets of anci ...[Read More]

Imaggeo on Mondays: Magnetic interaction
Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]
GeoPolicy: The importance of scientific foresight
Many of the issues that society currently faces are complex and research on just one angle or area does not provide sufficient information to address the problem. These challenges are compounded when more than one region (or even the entire planet) is impacted. Many of the decisions and legislations passed by governments today will go on to impact how these issues either develop or are resolved ye ...[Read More]
GeoSciences Column: Forests in flux – log-jams in the Amazon
Collapsing dams are a staple of disaster films, but the form that these take in natural systems is also surprisingly varied. Streams and rivers can be blocked by a range of rapid and gradual inputs. One of the lesser-known causes of stream blockage is through the accumulation of large woody debris – tree trunks and large branches – to form a log jam. The impact of these jams on river geomorphology ...[Read More]
Imaggeo on Mondays: Ice forming on Chesapeake Bay
Sandwiched between the U.S states of Mayland, Delaware, Pennsylvania, New York State, the District of Columbia and Virginia, lies Chesapeake Bay, the largest estuary in North America. It is of huge ecological importance: “the bay, its rivers, wetlands and forests provide homes, food and protection for countless animals and plants”, says the Chesapeake Bay Program. Up to 150 major rivers and stream ...[Read More]
