Seawater carbonate chemistry and carbonate chemistry in the microenvironment within cyanobacterial aggregates ...
Photosynthesis and respiration cause distinct chemical microenvironments within cyanobacterial aggregates. Here, we used microsensors and a diffusion–reaction model to characterize gradients in carbonate chemistry and investigate how these are affected by ocean acidification in Baltic vs. Pacific ag...
