New on StackExchange: Temporal Resolution of Seismic data

Radius of the Fresnel zone is given by where v: velocity of layer : two way travel time :dominant frequency in the spectrum This shows that high frequencies give better resolution than lower frequencies and resolution deteriorates with depth and increasing velocities. However I found some text in “Seismic Data Analysis- Yilmaz” which is contradictory. […]

Do we even need math? – Calculus in geophysics and geology

The amount of calculus in geophysics and geology degrees varies throughout every university and even in uni itself, there seldomly is a consensus on how much math is actually needed. Jascha Polet from Cal Poly Pomona asked a very interesting question on Twitter: Should every student who graduates from a Geology (not Env Sciences) MSc […]

To what accuracy and precision do we know the volume of the Earth?

Satellites such as GOCE and GRACE measure the geoid with unprecedented accuracy. Altimeters can determine local surface elevation with millimetre-precision. This makes me wonder: to what precision and accuracy can we measure (or calculate) the volume of the Earth? I’m a lay when it comes to solid Earth, and I find it surprisingly hard to […]

Lifesavers – Two tools in my daily worklife

Today I’d like to share two tools that I have found indespensible in the course of my studies. Ironically, these have nothing to do with geophysics or seismic at all. But they’re out to save you. Git Git is a very low-key version control tool. At certain points in the process of creating you can […]

Sometimes I wish this worked.

via George Takei Working with seismic data packages can be quite a hassle. The User Interface is stuck somewhere beyond the 80s’ and you wonder where you’re supposed to supply the punchcard. Has anyone tried this novel approach yet?

Lying with statistics

Lying with statistics.

You can see it quite often today, that an essential part of an axis is missing. I usually think highly critical of not showing your entire plot. Finally someone has made the appropriate visualization about lying with statistics. Baseline matters via Flowing Data from Reddit  

Disney Princesses (as) rock!

You know the Disney princesses. You have seen them reimagined as guys, as pregnant, across different ethnicities and bearded. Now finally geologists get their fair share of Disney reimagination as well. (Yes even more than the bearded ones.) I present to you the work of Kevin Bolk: Disney princesses reimagined as pile of rocks. Cherterella […]

Promax 2D Multiple Reduction

I am at a point, I could use some help with the program Promax 2D from Landmark Corp. I have posted in a LinkedIn group and this way I hope I may get some signal boost for my question. Do you have some experience with the following? Help a fellow Masters student out? I am […]

Dante’s Peak investigated

Dante’s Peak, one of those disaster movies that you either love or hate. Pierce Brosnan saves a dog from Old Smokey tantrum. In the role of a volcanologist we get quite a bit of action such as this scene: Now Rebecca Williams from the University of Hull has taken a closer look at the movie. […]
