Integrated Development Toolbox for Aquatic Chemical Model Generation R package AquaEnv version 1.0-5 CRAN Task View: ChemPhys (https://CRAN.R-project.org/view=ChemPhys) 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.
