   5. Compensation for Alkalinity source changes

We acknowledge and respect the lək̓ʷəŋən peoples on whose traditional territory the university stands and the Songhees, Esquimalt and W̱SÁNEĆ peoples whose historical relationships with the land continue to this day.

Note: 1 dbar is approximately the hydrostratic pressure for 1 meter of water depth

Recall that [CO$_3^{2-}$] $\approx$ ALK-DIC
