Solves seawater carbonate chemistry with PyCO2SYS for chemical oceanography, ocean acidification, and marine carbon-cycle research. Use for paired total alkalinity, dissolved inorganic carbon, pH, or seawater pCO2/fCO2 measurements; carbonate speciation; aragonite and calcite saturation; Revelle factors; lab-to-in-situ temperature and pressure corrections; and measurement uncertainty propagation. Applies to carbonate-system calculations, not general aqueous speciation or air-sea gas-flux…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Marine Carbonate Chemistry Turn two independent seawater carbonate measurements into a reproducible speciation table, mineral saturation estimates, and a record of the calculation assumptions. Targets **PyCO2SYS 1.8.3.4**, tested with Python 3.13 and NumPy 2.5.3. As reviewed on 2026-10-01, this remains the stable PyPI release. The [v2 documentation](https://mvdh.xyz/PyCO2SYS/) is for a beta with breaking changes; use the v1 documentation for this pin. ## When to use - Analyze bottle samples, shipboard carbonate measurements, or acidification experiments. - Calculate total-scale pH, seawater pCO2/fCO2, carbonate ion, aragonite/calcite saturation state, or the Revelle factor from a valid measured pair. - Convert a system determined at laboratory conditions to specified ocean conditions. - Quantify how stated measurement uncertainties affect the calculated results. This workflow concerns seawater carbonate equilibria. Freshwater, porewaters with substantial uncharacterized alkalinity, brines outside the selected calibration range, and reaction/transport models require additional chemistry and validation. Do not …

How to install
mdr add k-dense-ai/scientific-agent-skills/marine-carbonate-chemistry@sha256:03e58c7f9d7df75aThe line at the top of this page pins the label v1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
