ocean (version 0.2-4)

Biophysical Oceanography Tools

Description

This package contains a set of functions for manipulating and visualizing output from numerical ocean models. Many of the routines are targeted towards Lagrangian particle-tracking models with the data stored in NetCDF files. This package may be useful to spatial marine ecologists and biological or physical oceanographers.
