Calkulate: seawater total alkalinity from titration data

Calkulate

Calkulate is a Python package for finding total alkalinity from titration data using PyCO2SYS.

Installation

pip install calkulate
conda install conda-forge :: calkulate

Use

If the data for each individual titration is in its own text file and you have a spreadsheet containing the metadata for each titration on separate rows — all formatted as expected — then all you need to do with Calkulate is:

import calkulate as calk
data = calk.read_csv("path/to/metadata_file.csv").calkulate()
data.alkalinity  # <== here are your alkalinity results

For more detail, see the online documentation.

About

Calkulate is being developed primarily by Dr Matthew P. Humphreys at the Royal Netherlands Institute for Sea Research (NIOZ, Texel).
