seacarb is an R package that calculates parameters of the seawater carbonate system and includes functions useful for ocean acidification research. Version 2.4 has just been released. It provides three new functions and associated data sets. We are grateful to Andreas Andersson and Steeve Comeau who provided some of the code. Note that it may take a few days before the update is available for all operating systems and CRAN servers.
The new functions are:
- at (and dataset “alkalinity“): calculates total alkalinity from potentiometric titration data
- Pcorrect (and dataset “Pcoeff“): computes the pressure correction of equilibrium constants
- oMgCa: calculates the calcium carbonate saturation state for magnesian calcite
As always, bug reports (hopefully none!) and suggestions are welcome (gattuso(at)obs-vlfr.fr) and Héloïse Lavigne (heloise.lavigne(at)gmail.com).
