Decrease in aragonite saturation state through time.

The (a) surface saturation state for aragonite in 2100, with depth profiles for (b) the Atlantic and (c) the Pacific. White lines indicate previous saturation horizons (dashed, 1765; solid, 1994). Black lines indicate future saturation horizons (solid and dashed representing different emissions scenarios in 2100). Warm colors indicate oversaturation, so aragonite will remain intact, and cool colors indicate undersaturation, and aragonite will dissolve. (Orr, 2005)
