Short summary

The ocean helps to mitigate our impact on Earth's climate by absorbing about a quarter of the carbon dioxide (CO₂) released by human activities each year. However, once absorbed, chemical reactions between CO₂ and water reduce seawater pH (ocean acidification), which may have adverse effects on marine ecosystems. Our Python package, PyCO2SYS, models the chemical reactions of CO₂ in seawater, allowing us to quantify the corresponding changes in pH and related chemical properties.
