Marine life and Carbon cycling in a changing ocean: Integrating observations, AI, and models

Session ID#: 259523

Session Description:
Marine organisms and their ecological interactions play a pivotal role in ocean carbon cycling and storage, yet major knowledge gaps persist in how biodiversity and ecosystem processes shape these dynamics and how they will respond to climate change. Current Earth system models capture only limited aspects of the biological pump, and the complexities of microbial and planktonic communities, particle dynamics, and trophic interactions remain difficult to capture. Recent advances in imaging, omics, autonomous observations, trait-based models, and AI are opening new frontiers to investigate how biological structure and activity influence carbon pathways. We welcome contributions that integrate observational, experimental, and modelling approaches to better resolve how structure and function of marine ecosystems mediate carbon fluxes from surface production to deep-ocean export, and to identify feedbacks between biological processes and carbon cycling that may modulate the ocean’s role in climate regulation. The session seeks to foster interdisciplinary dialogue and support the next generation of models capable of capturing dynamic feedbacks between marine biodiversity, ecosystem function, and carbon cycling and storage in a rapidly changing ocean.
