Toolbox for the experimental aquatic chemist, focused on
acidification and CO2 air-water exchange. It contains all elements to
model the pH, the related CO2 air-water exchange, and
aquatic acid-base chemistry for an arbitrary marine,
estuarine or freshwater system. It contains a suite of tools for
sensitivity analysis, visualisation, modelling of chemical batches,
and can be used to build dynamic models of aquatic systems.
As from version 1.0-4, it also contains functions to calculate
the buffer factors.
