Oceanography is a discipline that works with a large variety of data sets, but good software to visualise or analyse such data is often rather expensive or has a restricted scope.

Karline Soetaert wrote a number of R-packages that are a valuable alternative to the existing oceanographic data visualisation tools.
Examples of their use to visualise complex oceanographic data or the output of 3-D hydrodynamical models can be found in the gallery below.
