GeoEd: Working together

When a geoscientist steps into a classroom, set to share their wonders of the Earth with a host of eager young minds, they are heading straight into unknown waters. Which students will rock the boat? What works well for this class and what should you steer well clear of? Not knowing the answers can turn a terrific outreach activity into a sinking ship. Fortunately, there’s a navigator on board.

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]

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]
