The ClimOcean project aims to the development of a methodology based on radiotracers to monitor the adaptation of marine species to Climate Change.
The goal is the study of the influence of the acidification of the seas and oceans on the growth of various species of coral, bivalves and echinoderms, as they are organisms that build their skeleton or their shell through the production of calcium carbonate.
The uptake of isotopes of Ca (41Ca, 45Ca) into the exoskeleton is used to determine the growth of those species, exposed to present and time projected (50-100 years) climatic conditions. Isotopic composition is determined by direct determination of the emitted radiation (45Ca) or with accelerator mass spectrometry (41Ca).
