Feminine field work.

It doesn’t matter how you dress! Or does it? So I’m a white middle-class guy, which makes me pretty privileged as it is. Please feel free to check yourself on the Male Privilige Checklist. And I have had a lot of learning to do when it comes to sexism and feminism (and I still do). […]

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 […]

The Amplituhedron – Turning physics inside out.

I like the seismics. I just love the concept how recording a superposition of waves can transport information about the subsurface. We send out carefully engineered noise to record noise and apply statistics to these huge data sets and in the end get an image we can interpret in regard to its geologic formation. This […]

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 […]

Phantastic Physics!

Guns and physics mix pretty well. While I don’t want to advocate gun use! Nevertheless, they’re still a marvelous example when it comes to trajectories and the like. So two weeks ago the Veritasium Youtube Channel posted a puzzling video involving a gun and a wooden block, but see for yourself: So what do you […]

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 […]

EBCDIC punch card from 1964.

How punch cards helped me get to know my data – EBCDIC

Today I learned something interesting. Old habits die hard and seismics is a pretty old business. There are a couple of standards for storing seismic data in file formats. One of them is the so-called SEG-Y standard. It starts with information about the data set called header and then the actual seismic data is written. […]
