The state of science on climate change

Reading about climate change can be overwhelming. There are many questions asked and many implications for humans. The typhoon on the Philippines shows once again that Earth is changing. But the data alone isn’t very telling. No one I know has actually read those reports or has understood them very well. What does it mean […]

Fourier and Space – The FX Domain

Geophysics can get a little fancy. You have probably heard the geophysicists tend to hang around some mathematicians. When it comes to the topic of math most of my friends like to state: “I was good at math until they started mixing in the alphabet!” I hear ya. Complex numbers and pi and variables are […]

Mama Etna is back!

One big reason to go into geophysics is pretty obvious: Volcanoes! I got to know Boris Behncke during my high school years. He’s a geophysicist situated in Sicily, Italy. And to our fortune he’s quite keen on photography and shares these gems on various platforms. The latest paroxysm produced a very special event: That moment, […]

Under Pressure – Multi-component seismic acquisition

Imaging the subsurface has become more and more complex. If we want to get a state-of-the-art image we might consider a slanted multi-component streamer acquisition and process it with a full waveform inversion to finish it off with a nice pre-stack Gaussian beam migration. Yeah… Even as a geophysics master student this is some tough […]

Is working in Oil & Gas immoral?

We often look at the Oil & Gas industry and wonder how anyone would be willing to work there. All the environmental catastrophes, the carbon footprint of cars powered by oil and lately the fracking business, they’re all deemed to be the devil institutionalized. So on Reddit, the question was asked: Is working in Oil […]

How to see the earth rumbling.

The Earth starts to shake. All the tension that was built up at the fault was released. An earthquake just happened somehow the ground starts moving. If you think about it, it’s fascinating how this energy can affect us several miles away from the actual earthquake. But how exactly does this work? At the fault […]

Like a Moss

They’re pretty much everywhere. In the harshest environments, even on highways some extremophile mosses, lichens and algae can survive. Most of them aren’t very welcome on the walls of our cities. Since they’re easier to remove than graffiti many house owners remove them first. But did you know these, so called, cryptogamic covers are huge […]

In Rough Seas

Heligoland is an island off the coast of Nothern Germany. This island has already had a turbulent history before man set foot on this island of red sandstone. But its position in the North Sea, between Germany and the UK, also has made this island subject to territorial quarrels and military interest. This interest has […]

Recording a seismic wave – What’s new?

Streamers are an essential part in the marine seismic experiment. When I first came into geophysics, I learned that streamers are fluid-filled hoses with pressure probes. This might be right in the case of our streamer at the university which isn’t quite up to par with the newest developments out in the industry. Oil-filled seismic […]
