Alexandra Delbot reçoit Laurent Chauvaud et Frédéric Olivier pour explorer les coquilles de bivalves comme archives des milieux marins. La discussion explique comment les stries de croissance et leur composition chimique renseignent sur l’âge, la température, la salinité et les climats passés. Elle aborde aussi les pollutions, les perturbations acoustiques et les réponses biologiques des mollusques, envisagés comme indicateurs des changements de leur habitat.
