The IT of the University of Potsdam is back online after an external attack. We are taking the opportunity to update the MRES blog technically. Until then, the blog is available, all data & code repositories for my publications are available. As you can easily see, the pictures are missing! We apologize, they will be visible again soon.
MRES 6th and PRES 2nd Errata Files
These is the for Python Recipes for Earth Sciences, 2nd Edition (Springer 2024) and MATLAB Recipes for Earth Sciences, 6th Edition (Springer 2024). Continue reading “MRES 6th and PRES 2nd Errata Files”
Probabilistic Age Modeling for Complex Stratigraphic Sequences
In an article published in Quaternary Geochronology (Trauth, 2014), I introduced a new method for modeling complex stratigraphic sequences. I would like to explain at this point what the result of the modeling is, and what it is not.

Displaying Sediment Records with both Age and Depth Axis with MATLAB
Sediment data is typically display in diagrams with two axes, a core depth axis and an age axis. Here is a MATLAB script to convert depths into ages and display a sediment parameter in a diagram with both age and depth axis. Continue reading “Displaying Sediment Records with both Age and Depth Axis with MATLAB”
Follow MRES/PRES on Bluesky!
Following the latest political developments and the involvement of the operator of X (formerly known as Twitter), there is a veritable exodus from X to Bluesky. Please follow me there at @martinhtrauth.bsky.social and please also note the very, very well-put together Bluesky starter pack for Quaternary Scientists, put together by Christine Lane from the University of Cambridge. See you there!
Drawing Pollen Diagrams with MATLAB
Palynologists traditionally use the software Tilia by late Eric Grimm to plot their data, which is also used by micropaleontologists. Here is a MATLAB script to create a diagram that is similar to the typical Tilia graphics.

Cluster Analysis with MATLAB
Cluster analysis creates groups of objects that are very similar to one another compared with other individual objects or groups of objects. The aim of the method is to gain insights into the structure of a data set without predefining categories and therefore cluster analysis is a method of unsupervised learning.

Online Courses in Modern Data Analysis Methods in Earth Sciences with Python and MATLAB
More than 30 years ago, I began teaching compact 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 is an overview of the current options!
