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 (pHn-shells) a CO2 vent site at Ischia, Italy. Four pH(low)-shells and four pHn-shells were sectioned transversally and scanned for polymorph distribution by means of confocal Raman microscop...
