Fig. 5: Calcium carbonate saturation state during both research cruises.

Vertical cross-shelf sections of (a, b) aragonite saturation state (Ωarag) and (c, d) calcite saturation state (Ωcal) during research cruises in 2015 and 2018. The dotted red line for Ω values represents the isopleths of 1; below such value is considered CaCO3 undersaturation. The black dots represent sample locations. Gray box represents an area with non-collected data.
