Am 26. September 2025 ist wieder Kinder-Universität an der Universität Potsdam. Ich bin wieder mit zwei Vorlesungen dabei, "Knochenjob in Ostafrika–Unterwegs auf den Spuren der ersten Menschen" und "Was war los im nördlichen Afrika, bevor es Pyramiden gab?".

Today marks the start of the 60th compact course based on my textbooks #MATLAB Recipes for Earth Sciences, 6th Edition (Springer 2025) and #Python Recipes for Earth Sciences, 2nd Edition (Springer 2024). I am looking forward to this new round of teaching online!

Artificial neural networks (ANNs) have been used for quite some time to identify, for example, flowers in easy-to-use apps on smartphones. Here's an #ANN with backpropagation in 6 steps, now with both #MATLAB and #Python code:

Multispectal imaging captures images across multiple spectral bands. Here is a #MATLAB example using #MAPIR cameras where eight different spectral bands in visible light and near infrared show differences in a rock sample that are invisible to the human eye.

Multispectral imaging of a Permian druse showing eight different wavelengths in the range of 450 nm and 850 nm in pseudocolor plots.

Agate druse, basalt, "melaphyr", 290 million years, Permian, Waldhambach, Germany, shot with a Nikon Z fc with a Nikkor Z MC 50 mm 1:2.8, auto focus. Width of the druse is about 10 cm.

Thanks to the ongoing support of MathWorks Inc. through their Curriculum Development Program, I was able to purchase two more spectral cameras. Here is an example of how to import and process the images of an agate druse sampled from a Permian basalt in #MATLAB:

More than 30 years ago, I began teaching courses on data analysis in the earth sciences. 20 years ago, I started thinking about writing textbooks. Now there are six textbooks and many different course formats for you. Here are the options for you:

As part of upcoming ICDP KIND workshop this weekend on Lake Kinneret Drilling, I will give a presentation on climate time series analysis, methods, and applications. I have compiled a list of courses, books, and papers by us during the last decade:

Yesterday, I had a visit from an 11th grade class from a high school. I gave a talk on the climate tipping point 5,000 years ago and ancient Egypt, and had the students solve some problems using AI. It was alarming to hear that AI is not a topic covered in class. #geoscience

Potassium is a proxy for aridity in Chew Bahir, Ethiopia, due to the increasing illitization of smectites in a gradually drying lake. V Förster and colleagues have investigated this in detail—and last year we showed that this was even the case 379 kyr ago, as found at a core at 200 m. #geoscience

Very interesting open access article about the "Long-term impact and biological recovery in a deep-sea mining track" by D.O.B. Jones and colleagues. Their photos of the ocean floor after mining, before and after, are simply shocking. #geoscience

Interesting, a complicated signal, thanks for explaining 😉

Martin H. Trauth @martinhtrauth.bsky.social · Jun 10

Really? Which interpolation method are you using then?

Actually, I would have expected you to simply bandstop out the 12.4-hour period or to FFT the data, remove the 12.4 spectral peak, and then iFFT it? I did this with periodic noise in microscopic images:

In #geosciences, time series are usually not evenly spaced – but most methods for analyzing these time series require this property. Here is an introduction to the art of #interpolation, including potential pitfalls and how to overcome them with MATLAB + Python:
