Description du projet
Le rôle des nouveaux écosystèmes polaires dans le climat mondial
La rapidité du changement climatique dans les océans des hautes latitudes entraîne l’émergence de nouveaux écosystèmes dans les régions côtières et en haute mer. Partant de ce constat, le projet SEA-Quester, financé par l’UE, explorera ces écosystèmes polaires émergents, en évaluant leur potentiel de séquestration du carbone bleu, leur impact sur la biodiversité marine et leur rôle dans le système climatique mondial. Il examinera toutes les formes de carbone bleu présentes dans les écosystèmes marins côtiers, pélagiques et benthiques, et développera un système de comptabilisation de celui-ci. SEA-Quester établira une méthode pour quantifier le compromis entre la récolte de la biomasse marine et sa contribution nette à la séquestration du carbone par le biais du facteur d’amplification biomasse-séquestration. Il fournira également des recommandations.
Objectif
The rapid pace of climate change in high latitude seas is promoting the emergence of novel ecosystems in coastal regions as well as in the open ocean. SEA-Quester, in accordance with the work program (HORIZON-CL6-2023-CLIMATE-01-3), will conduct field surveys, process studies and model analyses to improve our understanding of the causes and consequences of these emerging polar ecosystems; their potential for blue carbon sequestration, their implications for marine biodiversity, and their role in the global eco-bio-geo-chemical climate system. SEA-Quester will do so with a rigorous analysis of blue carbon stocks and their dynamics, laying the foundations for a fit-for-purpose blue carbon accounting with balance sheets for not just carbon sequestration, but other impacted marine ecosystem services such as fisheries production. SEA-Quester considers all forms of blue carbon in coastal, pelagic, and benthic novel marine ecosystems, living and dead, in the water column and in the sediments, and uses a mechanistic approach to reduce uncertainties in model predictions. A key outcome of SEA-Quester will be to develop a thorough means of quantifying the trade-off between harvesting marine biomass and its net contribution to carbon sequestration: the Biomass-Sequestration amplification factor. SEA-Quester will ensure effective exploitation of the project results in international scientific assessments of Blue Carbon potential and by policy-makers (specifically targeting Nationally Determined Contribution estimates), to ensure dialogue, communication and dissemination to National and European governmental bodies, European citizens and NGO’s, and to provide recommendations for optimizing the monitoring of biodiversity and ecosystem services in emerging polar environments.
