Abstract. A substantial body of research now exists demonstrating sensitivities of marine organisms to ocean acidification (OA) in laboratory settings. However, corresponding in situ observations of marine species or ecosystem changes that can be unequivocally attributed to anthropogenic OA are limited. Challenges remain in detecting and attributing OA effects in nature, in part because multiple environmental changes are co-occurring with OA, all of which have the potential to influence marine ecosystem responses. Furthermore, the change in ocean pH since the industrial revolution is small relative to the natural variability within many systems, making it difficult to detect, and in some cases, has yet to cross physiological thresholds.

Global stressors, such as ocean acidification, constitute a rapidly emerging and significant problem for marine organisms, ecosystem functioning and services. The coastal ecosystems of the Humboldt Current System (HCS) off Chile harbour a broad physical–chemical latitudinal and temporal gradient with considerable patchiness in local oceanographic conditions.

Global warming is expected to lead to shifts in species' geographic ranges to track preferred temperatures.

Appel à communication : Plus de trois milliards d’êtres humains dépendent directement ou indirectement des océans pour subvenir à leurs besoins. L’océan mondial est pourtant soumis à des perturbations anthropiques croissantes : pollution, dégradation et/ou perte d’habitats, eutrophisation, invasions biologiques, changement climatique ou encore exploitation des ressources. Autant de pressions qui affectent le fonctionnement des écosystèmes, les biens et services qu’ils fournissent et le bien-être des populations qui en dépendent. « Conserver et exploiter de manière durable les océans, les mers et les ressources marines aux fins du développement durable » définit le 14ème des 17 objectifs de développement durable (ODD 14) du Programme 2030.
