This PDF file includes:

  • Fig. S1. Simultaneous measurement of pH and carbonate by two LIX microsensors in the same location (distance between sensor tips, <10 μm) of the ECM within the growing edge of a S. pistillata microcolony.
  • Fig. S2. pH profiles measured in the polyps of different microcolonies of S. pistillata by entering a pH LIX microsensor through the polyp mouth (≈0 μm).
  • Fig. S3. Carbonate depth profile measured by entering a CO32− LIX microsensor through the polyp mouth (at ~200 μm) of a S. pistillata microcolony.
  • Fig. S4. Retraction of the coral polyp upon microsensor insertion.
  • Note S1. Derivation of Eq. 1 to calculate DIC.
  • Note S2. Calculation of the compound SD for DIC and Ωarag.
