Limpets counteract ocean acidification induced shell corrosion by thickening of aragonitic shell layers
Specimens of the patellogastropod limpet Patella caerulea were collected within (pH low -shells) and outside (pH n -shells) a CO 2 vent site at Ischia, Italy. Four pH low -shells and four pH n -shells were sectioned transversally and scanned for polymorph distribution by means of confocal Raman micr...
