Title	Nitrogen biogeochemical cycling in estuarine and coastal ecosystems
Convener	Lijun Hou, East China Normal University, China Yanling Zheng, East China Normal University, China Nengwang Chen, Xiamen University, China Xiaofei Li, East China Normal University, China
Description	Nitrogen (N) is entering Earth's land surface at more than twice its natural rate due mainly to the production and widespread application of N fertilizer and combustion of fossil fuels. Much of the anthropogenic N is delivered to estuarine and its adjacent coastal ecosystems, which results in substantial reactive N enrichment. This N pollution continues to threaten the ecology health of estuaries and coasts and cause serious environmental problems ranging from eutrophication to hypoxia and aquatic acidification. Therefore, it is important to improve the understanding of N transformation processes in estuarine and coastal environments, which may provide important scientific basis for the environmental management, ecological protection and restoration of these important ecosystems. This session provides a platform to discuss new research and significant advances related to the N cycling processes in the complex estuarine and coastal ecosystems. The themes of the session could include (but not be limited to): Nitrogen cycling processes and associated effects in complex estuarine and coastal wetlands. Controlling factors of nitrogen cycling across the estuarine-coastal continuums. Community dynamics of nitrogen cycling microbes. Ecological role of nitrogen cycling microbes. Response of nitrogen cycling to climate change and human activities. N2O emission dynamics. Coupling of nitrogen cycling with other elements.

Title	Social-oceanographical modeling to promote decision-making of coastal resilience in the Sustainable Development Goals（SDG）
Convener	Mingbao Chen, Macao University of science and technology/Sun Yat-sen University/Southern Ocean Science and Engineering Guangdong Laboratory（Zhuhai） Jiaxue Wu, Sun Yat-sen University/Southern Ocean Science and Engineering Guangdong Laboratory（Zhuhai） Limin Han, Ocean University of China
Description	The Sustainable Development Goals (SDGs) of the United Nations Agenda 2030, which thoroughly address inequalities and sustainable development in the social, economic and environmental dimensions in an integrated manner, represent an ambitious blueprint for achieving a sustainable future for all humankind. Achieving the SDG will require an integrated approach to the governance of ocean and coastal resources that involves all stakeholders, and considers how ocean and coastal resources link different sectors of society in order to improve the effectiveness of decision-making. To date, however, limited consideration of interactive feedback between the natural, technological and social dimensions of the human-ocean system, overly fragmented natural and social science research, and insufficient stakeholder engagement have led to ineffective governance of coastal resilience. Oceans and coastal, are widely recommended by academics to adopt socio-ecological systems approach to research to contribute to realizing of SDGs. Social oceanography, as an emerging discipline, provides a mechanistic explanation of the possible feedback mechanisms that may arise from the nonlinear interactions between different spatiotemporal scales of socio-oceanographical systems, and transforms the adaptive heterogeneity, power relations, trust, cultural beliefs, and cognitive biases of human society into endogenous elements of the system, Thus transforming the traditional decision-making process of separating humans from the ocean into a decision-making process that emphasizes mutual feedback. To this end, new methods and models need to be developed to reveal and measure the two-way feedback loop mechanisms and interactions between socio-ocean systems in the process of coastal resilience governance, and to promote the science of decision-making. This session welcomes top-down, bottom-up and comprehensive modelling studies of two-way feedback loop and interactions of socio-ocean systems involved in coastal resilience, transdisciplinary studies of integrating natural and social sciences in socio oceanography, as well as case studies of decision-making and governance processes that consider socio oceanography.

Title	Response and resilience against natural hazards: science, policy and community engagement
Convener	Sourav Paul, Estuarine and Coastal Studies Foundation, India
Description	Natural hazards such as flush floods, tropical cyclones, hurricanes, typhoons and tsunamis are disrupting the estuary and coasts. Climate change has further aggravated their impacts. Ecological systems such as from molecules to ecosystems aren't able escape the wrath of such temporary to prolong disruptions. The humans which depend on ecology for their daily lives and livelihoods are therefore impacted and are trying to find solutions through science based management of those stochastic disturbances. Most countries across the world neither have definitive ecological monitoring and/or resilience protocols to put forward a global strategy (with some degree of local specific modifications) against natural hazards affecting estuaries and coasts. So, the questions are 1. development of ecological indicators of natural hazard management of estuaries and coasts 2. establishment of regional monitoring systems targeted to specific natural hazards 3. involvement of coastal communities, academia, and policy makers for adopting ecological solutions. The above theme shall encourage all the papers that are Developing ecological monitoring protocols including those with ecological economic aspects Describe and delineate changes of the local to regional perspectives of different natural hazards affecting the estuaries and coasts Development of ecological indicators for natural hazard management Use of bio-engineering to protect (or at least lessen the impacts) estuaries and coasts from natural hazards Ecological science based policy framing against any specific natural hazard to estuaries and coasts Ecological monitoring, resilience build by involving local community to combat against natural hazards

Title	“Source-to-Sink” processes across the river-estuary-coast shelf continuum under changing climate and human activities
Convener	Aijun Wang, Third Institute of Oceanography, Ministry of Natural Resources, China Chui Wei Bong, University of Malaya, Malaysia Pei Sun Loh, Zhejiang University, China
Description	Better understanding of the transport process and fate of terrigenous materials in the river-estuary-coastal shelf continuum, as well as the impact of climate change and human activities on these processes and their ecological and environmental effects, is of great significance for us to take appropriate measures for land-sea integration management, especially in the current context of "carbon neutrality", appropriate land-sea integration management strategies can improve the carbon sink potential of the river-estuary-coastal shelf continuum. For this special session, we are interested in the processes of materials transport, transformation and burial across the river-estuary-coastal shelf continuum, how climate change and human activities in the river basin interfere with these processes, and what impact these disturbances will have on the sedimentary environment and ecosystem evolution of the estuary and coastal shelf. In addition, we are also interested in how to take land-sea integration management measures to deal with the environmental changes of the river-estuary-coastal shelf continuum. We invite submissions that include sediment transport and sedimentation, geomorphological evolution, biogeochemical cycles, carbon ‘Source-to-sink’ transform processes across river-estuary-coastal shelf continuum, especially the transformation of above processes under the influence of climate change and human intervention. Submissions may be theoretical, case study specific, or involve comparative analysis. We are interested in studies are considering the river-estuary-coastal shelf continuum as a whole system, from the theoretical research of material transport process to ecosystem response, and then to management countermeasures.

Title	Biogeochemistry and hydrology across the land-ocean continuum in the coastal transition zone
Convener	Bradley Weymer, Shanghai Jiao Tong University, China Ruifang Xie, Shan ghai Jiao Tong University, China Mark Hopwood, Southern University of Science and Technology, China Yan Zheng, Southern University of Science and Technology, China
Description	The transfers of carbon, nutrients and pollutants in water and sediments across the land-ocean continuum are important drivers of ecosystem dynamics and biogeochemical budgets. Strong gradients in turbidity, redox dynamics and carbonate chemistry combined with physical mixing processes make the coastal transition zone a hotspot for biogeochemical transformations affecting the fluxes, lability and bioaccessibility of chemical species. Understanding these transformations across diverse coastal zones is critical for assessing the viability of ocean management strategies including blue carbon storage, ocean alkalinity enhancement and the mitigation of anthropogenic pollution. Yet the coastal transition zone is challenging to study requiring research that bridges terrestrial/inshore and offshore surveys. We welcome submissions of studies that are multidisciplinary, combining different methodological approaches and/or contrasting different coastal regions in order to understand coastal transition zone dynamics.

Title	Dynamics of organic carbon cycling at the land-ocean interface
Convener	Peng Yao, Ocean University of China, China Zhuoyi Zhu, Shanghai Jiao Tong University, China Hongliang Li, Second Institute of Oceanography, Ministry of Natural Resources, China Bin Zhao, First Institute of Oceanography, Ministry of Natural Resources, China
Description	Estuaries and coastal areas are important ecosystems that connect land and ocean. They play a crucial role in the transfer and transformation of organic carbon (OC) and other biogenic elements from both marine and terrestrial sources. The carbon cycle in these regions is an important component of the global carbon cycle budget. However, human activities and climate change can impact the carbon cycle in estuaries and coasts at different time scales (e.g., seasonal, decadal, century, and millennial) through various environmental changes, such as changes in terrigenous inputs, organic matter production, hydro- and sediment dynamics, due to increased population growth, damming, land use, temperature and precipitation changes, etc. Understanding how the differences of OC cycling in different regions of estuaries and coasts are integrated and/or isolated from the large-scale signals of ocean carbon cycle, requires better constraints on temporal and spatial variability of key drivers in these dynamic systems. This session aims to bring together researchers studying the sources, exchanges, and fates of OC in water, particles, and sediments and their complex interactions within estuarine and coastal regions and how anthropogenic activities and climate change have altered the carbon cycle. We encourage submissions that use diverse methodologies and consider different time scales to improve our understanding of the dynamics of OC cycling at the land-ocean interface.

Title	Knowledge Co-Production in the Implementation of Closed Season in Africa
Convener	Victor Owusu, University of Education, Winneba, Ghana. Moses Aadjei, School of science and the environment, Memorial University, Canada
Description	This panel presents narratives on marine conservation initiatives in Africa , focusing on knowledge co-production towards the implementation of fishing bans and how conservation initiatives would help improve coastal livelihoods and marine sustainability. Small-scale fisheries (SSF) constitute the larger source of fish production in the marine sector, providing direct and indirect jobs to an estimated 260 million people around the globe . This includes a significant number of women both in the fishing and fish processing sector who can account for 50% of fishing employment in some regions. As part of wider fisheries governance initiatives, conservation has been deployed as an important management strategy in the rebuilding of depleted marine fish stock. Globally, closed seasons are considered as one of the key fisheries management procedures to help protect fish stocks and also increase their population. Closed seasons are observed as a way of reducing fishing pressure on stocks when they are most productive in terms of allowing the fish a chance to lay their eggs to replace the lost population due to fishing and other natural causes. Several countries in Africa including Ghana, Cote Dvoire, Benin amongst others are implementing seasonal closures to restore depleted marine fish stock, improve livelihoods and conserve marine resources. A major challenge with marine conservation initiatives in Africa concerns the non-involvement of fishers in decision making, inadequate sensitization or awareness creation, non-compliance by fishers, lack of alternative sources of livelihood, timing of closed season and lack of enforcement. This section scrutinizes marine conservation challenges in coastal Africa and explores various options in relation to the integrating of local opinions, traditional knowledge systems into fisheries management tools such as closed season. This panel invites papers that investigate marine conservation initiatives in Africa with a focus on closed seasons and marine protected areas.

Title	Estuarine & Coastal Sciences in Ice Cover Seas
Convener	Jiechen Zhao, Harbin Engineering University Bin Cheng, Finnish Meteorological Institute Fengming Hui, Sun Yat-Sen University
Description	Ice covered Estuarine & Coastal seas, in Arctic, Antarctic and high latitude oceans, are a substantial part of the world's Estuarine & Coastal ocean. For example, the Arctic shelf area alone comprises approximately 25% of the total shelf area of the world oceans. The introduction of a seasonal ice cover adds another dimension to the already complex processes which define the circulation in shallow coastal seas. The ice cover serves to alter both the exchanges of heat fluxes and surfaces stresses between the atmosphere and ocean, In addition, the growth and decay of sea ice causes a seasonal adjustment to the stratification of the ocean by salinating the surface layer in winter when ice grows and freshening the surface layer in summer when ice melts. Adding the complexity of a sea ice cover to coastal processes makes it a more challenging region over which to understand the interactions of ocean Estuarine & Coastal processes.

Title	Environmental change affecting COastal ecosystems of tropical China during the Anthropocene: Landward vs. OCeanic influence (ECOLOC)
Convener	Hongwei Zhao, Hainan University, Haikou, China Xiaoping Diao, Hainan University, Haikou, China Shiquan Chen, Hainan Academy of Ocean and Fisheries Sciences, Haikou, China Tim Jennerjahn, Leibniz Centre for Tropical Marine Research (ZMT), Bremen, Germany and Faculty of Geoscience, University of Bremen, Bremen, Germany
Description	The aim of the ECOLOC session is to provide a platform for discussion and exchange on the natural and anthropogenic factors controlling the physicochemical and biogeochemical environment of tropical coastal ecosystems in China and the response of these coastal habitats and their organisms (benthos, corals, seagrasses) to the input of land-derived anthropogenic substances along the coast. The session builds on the results of a Sino-German project on the tropical island of Hainan, but also invites contributions from other areas in China and around the globe which are facing similar issues. We are expecting contributions which address one or more of the below-listed research questions in the global coastal zone. Major research questions: What are the major inputs (nutrients, organic matter, organic contaminants, pathogens, trace metals) resulting from human activities and what are their pathways in the environment? How does eutrophication affect water quality in terms of dissolved oxygen concentration and pH as well as the emission of greenhouse gases (CO2, CH4, N2O)? How do coastal organisms (benthos, corals, seagrasses) respond to the increasing input of anthropogenic substances and associated impacts on water quality? As mangroves are lost to aquaculture: do seagrass beds serve as a nutrient, pathogens and organic matter buffer for coral reefs? What is the role of upwelling for circulation and nutrient input into the coastal zone (of Hainan), does it promote productivity and other biological activities there? What are the trends of coral reefs, seagrasses, and mangroves in China during the past decades?

Title	Blue Carbon ecosystem assessment, restoration and accounting
Convener	Xiaoxuan Gu, Xiamen University, China Xuedu Lu, Tencent Co., China Xi Liang, University College London, UK Michael Lochinvar Abundo, OceanPixel, Singapore
Description	Blue carbon sequestration assumes a pivotal role in our collective response to global climate change. Under the sweeping goals to achieve carbon neutrality affirmed by both China and the world at large, the importance and functional capabilities of blue carbon magnify, transforming it into an indispensable linchpin for global climate administration. In this session, our endeavor concentrates on invigorating and enhancing pioneering and foundational research in carbon sequestration within the domain of coastal blue carbon ecosystems. Our aspiration encompasses exploring a multitude of methodologies to unlock the potential of blue carbon, delving deeper into its latent capabilities, and formulating universally applicable standards for blue carbon sequestration and its associated frameworks, thereby amplifying the inherent advantages that blue carbon presents in the battle against climate change. Our discourse will pivot around and invite submissions to three cardinal domains: 1.We actively seek the quintessence of knowledge and experience drawn from scientific explorations on the carbon cycles within blue carbon ecosystems. This quest embraces a wide spectrum of researches, such as practical observation databases, monitoring techniques, and etc. 2.We harbor an ardent interest in exploring progressive initiatives directed toward the evolution of blue carbon in combination with other ecosystem services. Especially pertinent is the pursuit of strategies that connect the scientific monitoring of blue carbon with commerce, fortified by empirical evidence that substantiates the transition from academic research to pragmatic solutions. 3.Our discourse values insights into the coexistence of socio-economic development and environmental preservation, with a particular focus on a balance between blue carbon ecosystem restoration and sustainable community development. Our session builds on results of the Chinese BLUE-CARE (Blue Carbon Ecosystem Assessment, Restoration and Accounting) project, but we also invite contributions from other areas in China and around the globe which are dealing with similar issues.

Title	Compound weather, climate and biogeochemical extreme events
Convener	Feng Zhou, State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources, China Wenyan Zhang, Helmholtz Center Hereon, Germany Liang Xue, First Institute of Oceanography, Ministry of Natural Resources, China Delei Li, Institute of Oceanology Chinese Academy of Sciences, China
Description	Compound extremes are a combination of multiple drivers and/or hazard factors that can cause more severe societal or environmental risks compared to individual hazards. Considering the increasing frequency and intensity of these events due to global warming, it is crucial for us to collectively examine the broader picture. This involves understanding not only the changes and underlying mechanisms of compound extremes, but also their far-reaching and multifaceted impacts on marine ecosystems. The focus of this session is to understand how events like heavy precipitation, cyclones, marine heatwaves, harmful algal blooms, ocean acidification and marine oxygen depletion intertwine to create compound hazards. Also, we will explore the multi-scale spatial-temporal variability and their combined effects on marine life and carbon cycling. By integrating cutting-edge analytical methods, including artificial intelligence and numerical modeling, we aspire to advance our understanding of these complex dynamics. The goal is to enhance our ability to predict and manage the ecological consequences of compound natural hazards, contributing to the resilience and sustainability of marine ecosystems. We seek to foster a multidisciplinary dialogue, bringing together experts from various fields to discuss innovative research findings, share knowledge, and develop collaborative strategies. This session will address the urgent need for a holistic approach to studying and mitigating the impacts of natural hazards on marine environments. Join us in this crucial conversation at ECSA 60, as we collectively strive to deepen our comprehension of these dynamic environmental challenges. Together, we can pave the way for more effective management and preservation of our precious coastal ecosystems in the face of complex natural threats.

Title	Deepening knowledge on the resilience and responses of estuarine ecosystems under climate change
Convener	Hui Liu, Texas A&M University at Galveston, USA Hongsheng Bi, The University of Maryland, USA
Description	Estuaries experience vulnerabilitiesfrom natural and anthropogenic stressors across diverse scales. Particularly,hurricanes and typhoons, as climate-related cyclonic events, deliver acute disturbances with long-lasting effects on estuarine ecosystemsglobally.Existing studies indicate a rise in the intensity and frequency of the cyclonic activities under extreme climate scenarios, which provide an opportunity to explore ecosystem responses and resilience, contributing to strategic conservation and management.However, investigations often isolate ecosystem components without considering chronic impacts or ecological predictability in areas of recurrent disturbances, leaving a gap in comprehensive understanding of responses and resilience of estuaries regarding climate change. This session aims to address these challenges by inviting contributionsonwater quality, benthos, phytoplankton, zooplankton, and fisheriesat molecular to ecosystem levels using experimental, observational, and modeling approaches. It seeks to enhance our understanding of stress responses and resilience in these critical environments, and the subsequent impacts on ecosystem functions and ecosystem services. Additionally, this session will highlight the role of advanced technologies in observation and monitoring, enriching our insights and fostering international collaboration in estuarine research amid climate change, thereby identifying key research gaps and stimulate further discussions.

Title	Coastal wetlands: processes, interactions and evolutions
Convener	Zhan Hu, Sun Yat-sen University Zeng Zhou, Hohai University Yaping Wang, Nanjing University Mark Schuerch, University of Lincoln
Description	Coastal wetlands are dynamic and diverse ecosystems that serve as essential buffers between land and sea, providing valuable services such as coastal protection, carbon storage, habitat support for wildlife, and fisheries enhancement. Over the past decades, researchers have increasingly recognized the crucial role of coastal wetlands in various morphological processes and their interactions with surrounding environments. The processes, interactions, and evolutions of coastal wetlands have become a significant focus of research due to their vulnerability to environmental changes, including sea level rise, climate change, and human activities. Understanding the intricate connections and feedback mechanisms within these ecosystems is vital for effective conservation and sustainable management. In recent years, there has been a growing scientific interest in the processes, interactions and evolutions of coastal wetlands, both from a fundamental perspective (e.g., sedimentation and geomorphology) and a practical perspective (e.g., in the management of coastal wetlands). With the growing interesting on Coastal wetlands in various research contexts, we propose to create a session with the theme of "Coastal wetlands: processes, interactions, and evolutions" to gather a coherent set of high-quality research papers dedicated to this rising topic.

Title	Estuarine and deltaic coastal resilience with nature-based solutions
Convener	Wei Chen, Helmholtz-Zentrum Hereon, Germany Agustín S. Arcilla, Universitat Politècnica de Catalunya, Spain Fei Chai, Xiamen University, China Xiuzhen Li, East China Normal University, China
Description	Estuaries and deltas are vulnerable geomorphic features of coastal zones, providing vital habitats and shelter for living species while hosting significant economic values. However, these regions are facing increasingly challenges from the cumulative impacts of intense human activities, such as land reclamation, shipping and constructions. Additionally, climate change, including sea-level rise will enhance these impacts across different temporal-spatial scales. Nature-based solutions (NBSs) are used as an adaptation measure to provide a low carbon footprint solution for disaster risk reduction, while contributing to building sustainability, resistance, and resilience in these threatened coastal systems. The proposed session aims to share and discuss the most recent advances in NBSs, addressing the various disciplines converging on coastal restoration, with a particular emphasis on vulnerable estuarine and deltaic systems that require upscaled restoration at the ecosystem services to safeguard coastal functions. Such restorations will demonstrate the benefits of ecosystem services when compared to traditional engineering, in alignment with several initiatives (e.g. Coast Predict-Ocean Decade, REST-COAST EU Green Deal project, EDITO Model Lab and the Chinese MECR project). We invite submissions addressing innovative solutions to enhance the resilience of estuaries, deltas and other vulnerable coastal regions such as urbanized coasts. Contributions are encouraged from scientific analyses, monitoring studies, modeling efforts, and sustainable coastal management practices that utilize NbS techniques. The scope of topics includes, but is not limited to, challenges related to coastal erosion, combined marine-riverine flooding, water quality, and biological/geomorphological changes from short-term (extreme events) to long-term (decadal climatic trends) time scales and multi-risk cascading effects. Additionally, contributions on the uncertainties in ecosystem service delivery or climate-compatible solutions are welcome.

Title	Lateral exchanges of carbon and nutrient in coastal blue carbon ecosystems
Convener	Fang Cao, East China Normal University, China Christian Sanders, Southern Cross University, Australia Fenfang Wang, Jimei University, China
Description	Coastal blue carbon ecosystems (mangroves, saltmarshes, seagrass) have been shown to be important in cycling carbon and nutrients along the estuarine continuum. By laterally exporting materials rich originating from these systems via tidal and porewater exchanges, blue carbon ecosystems have been shown to strongly influence the coastal biogeochemistry across the globe. Yet, we currently lack an accurate quantification of the flux and fate of the materials associated with the lateral exchanges, partly due to the complicated biogeochemical cycles within the blue carbon system and across the ecosystem-estuary interface. This is mainly due to the complexities involved in differing methodologies related to field monitoring. To better understand the function of coastal blue carbon ecosystems, it is imperative to better constrain the flux and understand the fate of the laterally exported nutrients and carbon. The purpose of this session will be to include scientific progress, novel methodologies, and datasets to better understand lateral carbon and nutrient export from various coastal ecosystems, including blue carbon habitats.

Title	Mainstreaming Nature-Based Solutions for transformative climate adaptation in marine coastal areas
Convener	Elisa Furlan, Centro Euro-Mediterraneosui Cambiamenti Climatici and Università Ca’ Foscari Venezia, CMCC@Ca'Foscari – Edificio Porta dell'Innovazione, 2nd floor – Via della Libertà, 12 – 30175 Venice, Italy Andrea Critto, Department of Environmental Sciences, Informatics and Statistic, University Ca’ Foscari Venice, I-30170 Venice, Italy Pierre Failler, Centre for Blue Governance, Portsmouth Business School, Richmond Building, Portland Street, University of Portsmouth, Portsmouth, PO1 3DE, United Kingdom Mindert de Vries, Stichting Deltares (Deltares), Netherlands
Description	Coastal marine and transitional ecosystems are among the most important regarding ecosystem service provisioning. However, these ecosystems are under increasing anthropogenic (e.g., eutrophication, dredging and dumping, sand mining, pollution, boating, coastal development) and climatic (e.g., sea level rise, increasing temperature, storm surges, hurricanes) pressures. Climate change is projected to affect these ecosystems increasingly adversely, while new risks are expected to emerge, resulting in a decrease in ecosystem services and resilience. Addressing current and future coastal risk requires urgent actions to mitigate the impacts from multiple hazards, and boost ecosystems’ resilience using flexible and adaptable solutions before they reach a tipping point where the resilience deficit makes it hard to restore the system in place. Implementing Nature Based Solutions (NBS) at scale require adequate monitoring and adaptive management schemes while delivering opportunities for low carbon footprint, circular use of resources, low tech maintenance, with the potential for significant and cascading ecological and societal benefits. Unlike traditional adaptation measures, focusing primarily on immediate responses, transformative approaches, like NBS, aim to reshape the fundamental structures and patterns that contribute to climate vulnerability, while supporting cumulative delivery of ecosystem services under current and future climate change scenarios. To be effective, NBS based adaptation strategies should meet certain enabling conditions which include: facilitated access to knowledge and data and digital services that are critical for a better system understanding and management of climate hazards; effective governance structures that involve local communities and stakeholders in decision-making processes and collaboration among various levels of government and sectors; adequate financial resources to support transformation initiatives.This session invites presentations on innovative approaches and applications unlocking the potential offered by cutting edge digital tools to evaluate and predict the across scale role and multi-hazard effectiveness of NBS for transformative climate adaptation in coastal marine and transitional ecosystems.
