Version history

Version 3: Pythonic

Calkulate v3 switches to an object-oriented approach. This makes working with individual titrations and handling large collections of them much less cumbersome.

PyCO2SYS is now used to determine equilibrium constants and estimate total salt concentrations from salinity, instead of replicating those functions in Calkulate.

Version 2: Python

Calkulate v2 transitioned from MATLAB to Python and added several additional alkalinity solvers. Despite being implemented in Python, the style was still rather MATLAB-esque.

Version 1: MATLAB

The original Calkulate v1 was a MATLAB implementation of the "half-Gran" alkalinity solver described by H15. The final version (v1.0.2) remains freely available.
