The increasing interest in human-environment interactions in the last decades has resulted in development of more accurate methods and techniques for palaeoenvironmental reconstruction. Thus, molluscs recovered from archaeological sites can provide information on past climatic and environmental conditions. Seawater temperatures (ST) can be reconstructed using geochemical techniques such as the analysis of stable oxygen isotope ratios on marine mollusc shells. In this paper we aim to reconstruct the evolution of ST in northern Iberia (Spain) from ~30 to 7 ka cal BP using oxygen isotope values obtained from the limpet Patella vulgata Linnaeus, 1758. Results show a correlation between reconstructed ST and data from the Greenland ice cores and from deep-sea sediment cores, but also the existence of some local variations.
