Here you will find the original data, tables and figures of the paper “Bioturbational mixing depth and carbon flux at the seafloor” by Trauth, Sarnthein, and Arnold, published in Paleoceonography in 1997.

A new paper by Nadine Berner, myself, and Matthias Holschneider shows a two-step transition in African climate at (2.35-2.10) Ma and (1.70-1.50) Ma associated with the reorganization of the Walker Circulation. Continue reading “New Paper About Plio-Pleistocene Climate Transitions in Africa published in Quaternary Science Reviews”
Did you get a compact disc for Christmas this year, or you just stream your music? Or, possibly you got an vinyl record and wonder why vinyl is gaining popularity again? Here’s why … Continue reading “Vinyls, Compact Discs and the Nyquist Frequency”
If you want to write code for geoscientific data analysis independent of the programming language, a comparison of the syntax helps. And there are many similarities, not least because the languages inspire each other, even in the names of functions, which makes trilingual coding easy. Here is an example. Continue reading “Similarities and Differences in MATLAB, Python and Julia Syntax”
It’s been almost 30 years since I started with MATLAB, coming from FORTRAN77, and at a time when Python was still in its infancy and 20 years before Julia was developed. In the meantime, Python seems to be more popular than MATLAB in the geosciences, but may soon be replaced by Julia – time for change, also for me!
Since 1 April 2016 all ASTER data products are free to all users. Here is an updated MATLAB script to import, enhance and georeference an ASTER image with MATLAB, different from that published in the 5th edition of MRES and the published earlier on this blog. Continue reading “Importing and Georeferencing TERRA ASTER Images with MATLAB, Part 2”
My blog post “Create Publishable Graphics with MATLAB, Part 1” goes viral! Matt Hank, subsurface data scientist and founder of Subsurface Underground, and Maurizio Petrelli, professor at U Perugia and author of the Introduction to Python in Earth Science Data Analysis book (Springer 2021), took up the challenge and converted my MATLAB code to Python! The result doesn’t look too bad I have admit! Continue reading “Create Publishable Graphics with MATLAB … or Python?”
The new textbook “Signal and Noise in Geosciences” (Springer 2021) introduces methods of data acquisition in geosciences using MATLAB together with inexpensive data acquisition systems, such as the sensors on board of smartphones, sensors that come with the LEGO MINDSTORMS set, webcams with stereo microphones, affordable spectral and thermal cameras.
