EGU journals now display the most recent Impact Factors

EGU journals now display the most recent Thomson Reuters Impact Factors (IFs), which were published on 29 July in Journal Citation Reports. Earth System Dynamics received its first impact factor (IF 2.771), while publications such as Geoscientific Model Development (IF 6.086), The Cryosphere (IF 4.374) and Solid Earth (IF 2.155), significantly improved its impact in the past year. Copernicus has a ...[Read More]

GfGD in Tanzania (2) – Monitoring Water Projects

In our post yesterday I discussed the upcoming YES Congress and 25th Colloquium of African Geology in Dar es Salaam (1 – on the map), and introduced the way in which GfGD will be contributing. Following these conferences I will be travelling the 1000+ km distance to Mwanza – a key Tanzanian town on the edge of Lake Victoria, and then proceeding (by boat and car) to Chato (2 – on ...[Read More]

GfGD in Tanzania (1) – Earth Sciences for Improving Livelihoods

The East African country of Tanzania is a remarkable place, home to Kilimanjaro, the Serengeti, the Ngorongoro Crater and (for the volcanologists reading this) Ol Doinyo Lengai. It was also visits to communities in the Kagera region of Tanzania in 2009 and 2010 that resulted in GfGD getting off the ground soon afterwards. Since then, Tanzania has been a place closely linked with our progress. In 2 ...[Read More]

Imaggeo on Mondays: Spectacular splatter – the marvels of a mud volcano

Mud volcanoes, unlike many others, do not extrude lava. Instead, they release glutinous bubbling brown slurry of mineral-rich water and sediment. They range in size from several kilometres across, to less than a metre – the little ones are known as mud pots, reflecting their diminutive nature. The world’s largest, though, is Lusi: a mud volcano in East Java that released an astonishing 180,000 cub ...[Read More]

1200 words to make sense of chaos: The Selker Scheme

1200 words to make sense of chaos: The Selker Scheme

This is an inspiring article by John Selker (Oregon State University) that was first published in the latest AGU Hydrology Section Newsletter (July 2014). John graciously offered to re-post it here… make sure you make it to his rules and a secret at the bottom. Being elected a fellow of the AGU was an amazing honor, and I thank  those who so kindly nominated me, somehow crafting a silk purse ...[Read More]

Geosciences Column: The Toba eruption probably did have a global effect after all

Almost everyone has heard of the Toba super-eruption, which took place on the island of Sumatra roughly 74,000 years ago, but the only evidence of tephra or tuff (volcanic fragments) from the eruption is in Asia, with nothing definite further afield. It has sometimes been thought that this huge eruption may have led to a volcanic winter, a period of at least several years of low temperatures follo ...[Read More]

Open geoscience

Not so long ago I was in a meeting with EGU’s young scientist representatives, who had gathered online to discuss the issues facing those early in their academic careers. One member of this dedicated team put forward a compelling notion: that the future of open access is in the hands of today’s early-career researchers. This post aims to answer the question that followed: “how could EGU’s te ...[Read More]

Imaggeo on Mondays: Entering a frozen world

Dmitry Vlasov, a PhD Student and junior scientist from Lomonosov Moscow State University, brings us this week’s Imaggeo on Mondays. He shares his experience of taking part in a student scientific society expedition to Lake Baikal. This picture shows icy shores of Lake Baikal – a UNESCO World Heritage Site and the world’s largest natural freshwater reservoir (containing about one fifth of Ear ...[Read More]

Geosciences Column: From the desolate to the diverse, a story of volcanic succession

When a volcano erupts and spews lava onto the surrounding terrain, it is merciless in its destruction. All that is green on the land is engulfed in flame, or buried by an insurmountable mass of molten rock. Whatever charred remains of what lies beneath it will not see the light of day once the lava cools, turning the landscape into a barren black mass of solid basalt. But volcanoes around the worl ...[Read More]
