After a train, the London Underground, another train, a flight, three more trains and a taxi (shared with people I had met on my way); I had arrived in a small Alpine village in the very north of Italy. The reason for this rather convoluted journey? To attend the Karthaus Summer School on ice sheets …[Read More]
When a PhD student publishes a new paper, of course he/she would like that other scientists will read the work. However, in a busy academic world with many institutional obligations, it might be hard to promote the work and the research you are performing. Social media and blogs, however, can play an important role in research visibility and …[Read More]
Trying to understand the reasons behind the global warming of our climate is a never ending quest for scientists across the geosciences. Scientists often rely on deciphering past change to help us understand, and perhaps predict, what might happen in the future. Many will be familiar with the common saying ‘the past is the key …[Read More]
As part of my PhD research, I spent quite a lot of time at the Fort Hoofddijk (informally known as The Fort) – the palaeomagnetic laboratory of the University of Utrecht (in the Netherlands). For a little insight into what carrying research out in a 19th Century bunker, housed within the grounds of the botanical …[Read More]
Deglaciation and formation of an ice rise with the ice-sheet model BISICLES. The simulation starts with an ice sheet in steady state that overrides a topographic high in the bed, close to the calving front. The sea level is then forced to rise steadily with 1 cm per year during 15 thousand years, and the …[Read More]
New research on crocodiles shows that a combination of changing sea levels and temperatures were responsible for driving their biodiversity over millions of years. Living crocodiles are threatened by climate change, with 10 out of 23 species at a high risk of extinction. As ectotherms, animals which require external sources of heat to function, they …[Read More]

This week’s photo is another mineralogy themed one. This photo shows beautiful, yet also flattened crystals of the mineral natrolite that has grown in an acicular habit from a central point making them look sort of like little snowflakes. Natrolite is a relatively common hydrated sodium, aluminum silicate mineral (Na2Al2Si3O10 · 2H2O) that often forms within the …[Read More]
The picture shows the Elbe Rivervalley, one of the major rivers of Central Europe. It was taken from the Bastei Bridge close to Rathen, which towers 194 meters above the Elbe River in the state of Saxony in the south-eastern Germany. This region belongs to the national park known as Saxon Switzerland. Together with the …[Read More]
Creating 1 Hz-seismograms in a 3-D Earth model, and comparing them to observed body waves, is a dream that’s today still too expensive for routine use. But even tackling the problem for a spherically symmetric Earth poses certain challenges. Recently, a new tool entered the stage (you might have followed the Solid Earth discussion): Instaseis …[Read More]
