From: Perspective on the response of marine calcifiers to global warming and ocean acidification—Behavior of corals and foraminifera in a high CO2 world “hot house”

Fig. 11

Planar variability in pH around the calcifying specimen of Ammonia sp. in seawater with the pH indicator, pyranine. The gradient in pH, which decreases toward the specimen, is mainly caused by proton diffusion away from the precipitation site. An image of foraminifera is superimposed on the pseudocolor pH image. Scale bars indicate 100 μm
