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.

高纬度海洋气候变化的快速步伐正在促进沿海地区和公海出现新的生态系统。SEA-Quester根据工作计划（HORIZON-CL 6 -2023-CLIMATE-01-3），将进行实地调查，过程研究和模型分析，以提高我们对这些新兴极地生态系统的原因和后果的理解;它们的蓝色碳封存潜力，对海洋生物多样性的影响，以及它们在全球生态生物地球化学气候系统中的作用。SEA-Quester将通过对蓝碳储量及其动态的严格分析来实现这一目标，为蓝碳核算奠定基础，其资产负债表不仅包括碳封存，还包括其他受影响的海洋生态系统服务，如渔业生产。SEA-Quester考虑了沿海，远洋和底栖新型海洋生态系统中所有形式的蓝碳，活的和死的，在水柱和沉积物中，并使用机械方法来减少模型预测的不确定性。SEA-Quester的一个关键成果将是开发一种彻底的手段，量化收获海洋生物量及其对碳固存的净贡献之间的权衡：生物量固存放大系数。SEA-Quester将确保项目结果在蓝碳潜力的国际科学评估中得到有效利用，并由政策制定者加以利用。（特别是针对国家自主贡献估计数），以确保与国家和欧洲政府机构、欧洲公民和非政府组织的对话、沟通和传播，并为优化新兴极地环境中生物多样性和生态系统服务的监测提供建议。
