@ClarkGRichards, one of oce developers, pointed out two mistakes I made in the original Water Mass Mixing post. One was the fact that I did not use conservative temperature from TEOS-10 (or at least potential temperature from EOS-10) for the T$-$S plot. That resulted in an inversion at the ...

Again another late post! I am still getting settle here in beautiful Salvador. Unfortunately, the bus strike, the World Cup preparations, and the protests are not helping our apartment search.

windspharm uses pyspharm, a python wrapper around SPHEREPACK. SPHEREPACK ...

This post is part of the Introduction to Geophysical Fluid Dynamics, 2nd Edition post series on converting the MatlabTM examples to python. Chapter 8 is about Ekman Dynamics. This chapter contains two m_files ekmanh.m and spectralekman.m where the former is the exact solution and the latter the spectral ...

In the last two posts I show how to geo-reference a aerial images from various online services. I also commented that Google Earth Image was probably the best option from up-to-date image in small and/or dynamic areas. But what if you need bathymetry data? What if your image is ...

This is a quick post updating the last one. Some people inquired me on the possibility of downloading a georeferenced image from an online service.
