分会背景介绍（Background）

Union Session 013：

海洋十年是联合国支持的一项重要的海洋科学运动，旨在解决全球海洋可持续发展面临的最关键问题。在本届会议上，我们邀请全球研究界就以下倡议进行合作：

1）建立仪器化海洋野外站和研究设施的国际网络；

2）共同设计和执行跨学科合作研究项目；

3）制定评估缓解和适应战略的评估框架；

4）协调能力建设倡议，促进公平的政策和社会意识。

具体而言，我们邀请大家关注以下方面：

1）通过陆海统筹实现海洋负排放；

2）通过整合增强碱度等各种方法，最大限度地提高海洋储碳能力；

3）保护生态系统生物多样性。

此外，我们倡导加强与地方、区域及全球的从业者、决策者及立法者的紧密联系与合作，在适应与减缓气候变化战略中实施公正的海洋治理。

Ocean Sciences 036：

滨海湿地是地球上最丰富的碳汇之一，其土壤和植被中储存了大量的碳。然而，气候变化和人类活动改变了生态系统的物理、化学和生物过程，给滨海湿地固碳潜力带来了许多不确定性。为了解决这些问题，本次会议汇集了不同群体的科学家来探讨生物、生态、地球化学、地质和影响这些地区碳封存的理论因素。通过合作讨论，我们将确定最紧迫的挑战，并提出提高滨海湿地碳汇能力的策略。本次会议构建了一个交流平台，旨在深入分享气候变化与人类活动对海洋负排放（ONCE）影响的独到见解。会议将致力于形成全面而切实的评估与建议，为包括气候变化专门委员会（IPCC）在内的决策者提供科学支撑。

The 2024 AGU (American Geophysical Union) Annual Meeting will be held from December 9 to 13 in Washington, D.C. The "Union Session 013 - Ocean Negative Carbon Emission Approaches for Mitigating Climate Change: Mechanisms, Practices, and Governance" organized by Professor Chuanlun Zhang from Southern University of Science and Technology, Professor Nianzhi Jiao from Xiamen University, Professor Kanchan Maiti from Louisiana State University, and Professor Adina Paytan from the University of California, Santa Cruz, and the "Ocean Sciences 036- The Impact of Climate Change and Human Activities on Carbon Sequestration in Coastal Wetlands and Strategies for Carbon Sink Enhancement" organized by Professor Siyuan Ye from Qingdao Institute of Marine Geology, China Geological Survey, Professor Ken Krauss from Wetland and Aquatic Research Center, U.S. Geological Survey, Professor Nuno Caiola from Climate Change, Technology Center of Catalonia - Eurecat, and Professor Nianzhi Jiao from Xiamen University, are now open for abstract submissions. Both oral presentations and poster displays are available. We warmly invite you to contribute to this session.

PS. We also have a Town Hall session sponsored by the UN Ocean Decade Progam “Ocean Negative Carbon Emissions (ONCE), theming “Eco-engineering approaches for marine carbon dioxide removal (mCDR): Strategies and challenges”, which will provide a platform for dialogues between panel members and the audience. We also have a booth in the exhibition hall to introduce the ONCE program. We welcome everyone to come and communicate with us on site.

Background

Union Session 013：

The United Nations Decade of Ocean Science for Sustainable Development (Ocean Decade for short) represents a significant ocean science movement, aiming to addressing the most critical issues of global oceans. In this session, we invite all research communities to consider, evaluate and advise on negative carbon emission approaches centering around the following initiatives:

1) establishing an international network of instrumented marine field stations and research facilities;

2) co-designing and executing interdisciplinary collaborative research projects;

3) developing an assessment framework for evaluating mitigation and adaptation strategies;

4) coordinating capacity-building initiatives and fostering equitable policy and societal awareness.

Specifically, we invite contributions focusing on:

1) exploring ocean negative carbon emission through land-ocean integration;

2) maximizing carbon sequestration in the ocean by integrating various approaches such as alkalinity enhancement; and

3) protecting ecosystem biodiversity. Furthermore, we advocate for equitable ocean governance of adaptation and mitigation strategies.

This involves fostering closer engagement with local, regional, and global industries, decision-makers, and legislators.

Ocean Sciences 036：

Coastal wetlands represent some of the Earth's richest carbon sinks, storing vast amounts of carbon within their soils and vegetation. However, climate change and human activities have altered the processes of physics, chemistry and biology that created many uncertainties in the carbon sequestration potential of these ecosystems. To address these complex issues, this session brings together a diverse group of scientists to explore a wide range of topics, including biological, ecological, geochemical, geological, and theoretical factors that influence carbon sequestration in these regions. Through collaborative discussions, participants will identify the most pressing challenges and propose strategies to enhance the carbon sink capacity of coastal wetlands. This session offers a unique opportunity to share insights into the impact of climate change and human activities on Ocean Negative Carbon Emissions (ONCE), will develop comprehensive assessments and actionable recommendations to guide policymakers and governmental agencies like the Intergovernmental Panel on Climate Change (IPCC).

Global ONCE

海洋是地球上最大的活跃碳库。实现碳中和，既要减排，更要增汇。海洋负排放，即主动增加海洋碳汇，既缓解减排压力又保障经济发展，是支撑碳中和的两全其美之策。厦门大学焦念志院士于2017年率先在国际上提出了海洋负排放国际大科学计划的构想与倡议，得到国内外科技界的积极响应，合作团队覆盖全球33个国家与地区的79家科研院所，形成“总部+基地+全球分中心”的国际合作新模式。2022年6月，海洋负排放国际大科学计划正式纳入“联合国海洋科学促进可持续发展十年”行动计划，成为联合国十年倡议计划框架下的大科学计划。
