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.

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!

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 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.

Shortly after this blog went online, I wrote down a short history of the MATLAB Recipes for Earth Sciences (MRES) book. Here is an update, just before the 6th edition is published. Continue reading “The Story of the MRES Book, Editions 1–6”

I just published a the 2nd edition of my textbook “Python Recipes for Earth Sciences” with Springer. This is the Python version of the MATLAB textbook “MATLAB Recipes for Earth Sciences” that will appear in its 6th edition later this year.

Since the Apple iPhone Pro has an infrared LiDAR built in, geoscientists have presented a variety of possible applications. One of the most attractive applications is the scanning of outcrops.

The popular online course on data analysis in the geosciences will be taught bilingual using the two leading programming languages and development environments MATLAB and Python in parallel on 16–20 September 2024. The course is based on my books MATLAB Recipes for Earth Science (Springer 2021) and Python Recipes for Earth Sciences (Springer 2022), of which new editions will be published in summer 2024.
