Surfing the Maelstrom of Saltstraumen

Maelstrom of Saltstraumen

The strongest tidal current in the world transports 400 million cubic meters of water in six hours. The waters reach speeds up to 20 knots or 25 mph. This causes some serious turbulence in the waters, generating these maelstroms. You can even visit them by boat. Remember the Caledonian folding at Saltstraumen from last week? […]

Caledonian Folding in Norway

Caledonian folding in Saltstraumen, Bodø, Norway

There are some rock faces that are simply spectacular, including this rock face in Saltstraumen, near Bodø in northern Norway. These fascinating folds have formed under distinct circumstances. About 490 – 390 million years ago the Caledonian Orogeny happened due to the continents of Laurentica, Avalonia and Baltica colliding. In Scandinavia, the collision involved Laurentica and Baltica only. The […]

Rethinking the Common Reflection Surface Processing Tool

I worked with the seismic processing algorithm Common Reflection Surface for the past years. During this time I have come to the following conclusion: CRS has a marketing problem. I have worked with CRS in university, at Fugro Seismic Imaging and Wester Geco, respectively Schlumberger. Its development is closely tied to advanced concepts like the […]

Challenger Deep

Exploring Challenger Deep

The Challenger Deep at the Marianna trench is the deepest point on earth measuring 10.91km. People used to think our oceans were pretty flat underneath the water and did measurements with a plumb. So when surveyors came to this particular point at this subduction zone the line proved to be too short. When tectonic plates […]

Ash plume over Europe

Progressing ash plume of Eyjafjallajökull

In May 2010 air transportation in Europe came to a halt, when Eyjafjallajökull on Iceland erupted. Now, two years after that eruption scientist have gathered and evaluated all kinds of data how the ash plume moved through Europe. This data taken from satellites, plane and the earth can help evaluate particle dispersion better and limit […]

Aran Islands, Ireland

Aran Islands, Ireland

The Aran Islands just off the coast of Ireland left geologists puzzled for a while now. On top of this cliff huge boulders are found. Up to now the only explanation for waves energetic enough to transport these rocks would be a tsunami. Unfortunately, at least for the explanation, no tsunami happened there since 1755. Now […]
