FEC成员的最新研究聚焦于中国一座沿海城市可持续性发展的跨学科、协同设计与适应性管理。这项突破性研究由中国科学院烟台海岸带研究所的科学家带领，其研究团队与荣成市地方政府、蓝色经济公司共同定义了气候变化背景下沿海可持续性面临的主要挑战。该研究多步骤的研究方法初步揭示了目前尚未解决的问题，并将之与其它问题共同考虑，并进一步确定了应该参与的利益相关方。研究参与者共同设计了一项适应性管理计划，当地政府与地区监管部门随后采用了其中的许多措施。研究的进一步主要成果是增进了利益相关方之间的知识交流，为其开展管理、制定政策与决策提供了信息，并提高了其对自然灾害与气候变化脆弱性的认识。这项案例研究的成功将为其他沿海城市的适应性管理以及气候变化下的可持续发展提供参考。
A new publication by FEC members focuses on transdisciplinary, co-designed and adaptive management for the sustainable development of a coastal city in China. In this breakthrough study, scientists from Yantai Institute of Coastal Research, Chinese Academy of Sciences led a team of researchers to work with local authorities of Rongcheng city and blue-economy companies to co-define the principal challenges for coastal sustainability, in the context of climate change. The multi-step methodology revealed previously unaddressed issues and allowed these to be considered alongside others. It also identified further stakeholders that should be engaged. The participants co-designed an adaptive management plan of measures, many of which were subsequently adopted by the local and regional regulators. Further major outcomes were the increased knowledge exchange between stakeholders to inform management, policy, and decision making, as well as raised awareness of vulnerability to natural hazards and climate change. The success of this case study provides a reference for the adaptive management of other coastal cities and their sustainable development in a changing climate.

本研究于2011年夏季在台湾南部高屏溪海底峡谷河口附近进行了现场实验，以获得详细的过程-响应数据，以了解高屏河口悬浮泥沙的动态。研究使用仪器记录温度、盐度、电流和波场、悬浮物的体积浓度(VC)和质量浓度(SSC)。潮汐周期的温度和盐度信号区分了来自河流羽流和峡谷的水团，它们交替主导研究区悬浮物的表面动力学。 陆源悬浮物聚集成更大的絮凝物，体积浓度、质量浓度较高，有效密度较低。相反，海源悬浮物的粒径一般较小，体积浓度、质量浓度较低，有效密度较高。在地表水中，悬浮泥沙的有效密度随粒径大小呈指数级下降。在底层水体中，体积浓度、质量浓度在高能波条件下较高，在非高能波条件下较低，悬浮泥沙的平均粒径呈相反趋势。水动力学对沉积物-水界面的影响体现在表层沉积物的粒度组成上。高能波浪条件下海床上的粉砂和粘土含量较低，而非高能波浪条件下海床上的粉砂和粘土含量较高。从过程-响应特征来看，底层水体悬浮泥沙存在两种状态：高能波条件下形成的悬浮泥沙平均粒径较小，有效密度较低；非高能波条件下形成的悬浮泥沙平均粒径较大，有效密度较高。在前一种状态下，波浪扰动控制着悬浮泥沙的动力学，将海底沉积物引入底水中并聚集成微絮凝物(<~125 μm)和大絮凝物(> ~125 μm)。悬浮泥沙粒径分布呈双峰型，较大的峰位于Kolmogorov微尺度(约250 μm)附近。这表明，强烈的湍流与显著的沉积物悬浮和絮凝作用也导致了大絮凝物的解体。随着波浪能量的消散，大部分悬浮泥沙(包括所有细颗粒沉积物)通过絮凝和沉积从底层水中去除。在非高能波浪条件下，底部水中的悬浮泥沙来自峡谷上游的水和河流羽流，受半日潮汐流的控制。非高能条件下悬浮泥沙粒径分布多为单峰型，峰值在100 ~ 300 μm左右，小于湍流Kolmogorov微尺度(350 μm)。因此，湍流强度对底层水中悬浮泥沙的絮凝起着关键作用。
A field experiment was conducted in the summer of 2011 to obtain detailed process–response data to understand the dynamics of suspended sediment off the Gaoping River mouth near the head of the Gaoping Submarine Canyon in Southern Taiwan. The temperature, salinity, current and wave fields, the volume concentration (VC) and mass concentration (SSC) of suspended sediments were recorded. Temperature and salinity signals over a tidal cycle distinguished water masses originating from the river plume and the canyon, which alternately dominated the surface dynamics of suspended sediment at the study area. Terrestrial–sourced suspended sediments aggregated into larger flocs, characterized by high VC, SSC, and low effective density values. Conversely, marine–sourced suspended sediments generally had smaller grain sizes, characterized by lower VC, SSC, and high effective densities. In the surface water, the effective density of suspended sediments decreased exponentially with size. In the bottom water, values of VC and SSC were higher under energetic wave conditions and lower under nonenergetic wave conditions, whereas mean size of suspended sediments showed an opposite trend. The hydrodynamics also affected the sediment–water interface, which was reflected in the grain size composition of surficial sediments. The silt and clay content on the seabed was lower under energetic wave conditions and higher under nonenergetic conditions. According to process–responses characteristics, suspended sediments in the bottom water were associated with two regimes: smaller mean size with lower effective densities formed under energetic wave conditions and larger mean size with higher effective densities formed under nonenergetic wave conditions. In the former regime, waves–induced turbulence dominated suspended sediment dynamics by entraining seafloor sediments into the bottom water and aggregating them into microflocs (<~125 μm) and macroflocs (> ~ 125 μm). However, the size distribution of suspended sediment showed a bimodal distribution, and the larger peak is close to the Kolmogorov microscale (around 250 μm). It suggests that strong turbulence associated with significant sediment suspension and flocculation also resulted in disaggregation of macroflocs. As the wave energy dissipated, most of suspended sediments including all fine ones were removed from the bottom water, via flocculation and deposition. Under nonenergetic wave conditions, suspended sediments in the bottom water were contributed from upcanyon water and river plumes, controlled by semidiurnal tidal currents. The size distributions of suspended sediment under nonenergetic conditions were mostly unimodal, with peaks around 100–300 μm, less than the Kolmogorov microscales of turbulence flow (350 μm). Therefore, it could be concluded that turbulence strength plays a key role in flocculation of suspended sediment in the bottom water.

河口悬浮泥沙在调节冲积作用和塑造地貌格局方面发挥着重要作用。然而，它可能会受到人类活动的强烈影响。长江口流域河口工程建设，包括长江上游三峡大坝（TGD）和河口深水航道工程（DWP）的建设，极大地改变了河口悬浮泥沙浓度（SSC）。在这项研究中，我们从总共 149 幅 Landsat-TM/ETM+/OLI 图像（从 1984 年到 2020 年）和 515 幅 GOCI 图像（从 2011 年到 2020 年）中检索了长江口的地表水悬浮泥沙浓度，以获得其长期动态。结果表明，SSC 预估模型表现良好，平均绝对百分比误差为 12.83%，均方根误差为 0.027 g/L。整个长江口不同分区的悬浮泥沙浓度对三峡大坝蓄水造成的排沙量减少的反应不同。三峡大坝蓄水后，内河口悬浮泥沙浓度迅速下降40.3%，而在河口最大浑浊带（TMZ）发现悬浮泥沙浓度变化滞后，近 5 年下降了20.0–30.0%。地方河口工程建设，如深水航道工程，也通过阻断浅滩和河道之间悬浮泥沙的横向输送，对河口悬浮泥沙浓度动态起到重要控制作用。我们的研究结果突出了工程建设对世界受河流影响的大河口悬浮泥沙浓度动态的强烈影响。
Suspended sediments in the estuary play an important role in regulating the erosion-accretion and shaping the geomorphological patterns. Yet, it can be strongly impacted by the human activities. Constructions of basin and estuarine engineering in the Yangtze River Estuary (YRE), including constructions of Three Gorges Dam (TGD) further upstream of the Yangtze River and Deep Waterway Project (DWP) in the estuary, have greatly modified the distribution of estuarine suspended sediment concentration (SSC). In this study, we retrieved the surface water SSC in the YRE from a total of 149 Landsat-TM/ETM+/OLI images (from 1984 to 2020) and 515 GOCI images (from 2011 to 2020) to obtain its long-term dynamics. The results indicate that the SSC estimation model performed well with a mean absolute percentage error of 12.83% and a root mean square error of 0.027 g/L. The SSC in the YRE demonstrated an overall declining pattern over the past 37 years, particularly during the flood season, which was related to the decrease in the sediment discharge of Yangtze River. The SSC in different sub-regions across the entire YRE responded differently to the reduced sediment discharge caused by the impoundment of the TGD. The SSC in the inner estuary responded promptly with a 40.3% decline noted immediately after the impoundment of the TGD, whereas hysteresis of SSC changes was found in the estuarine turbidity maximum zone (TMZ) and have begun to decline by 20.0–30.0% in the recent 5 years. Constructions of local estuarine engineering, such as the DWP also exert important controls on the estuarine SSC dynamics by blocking the lateral transport of suspended sediments between the shoal and the river channel. Our results highlight the strong influence of engineering constructions on the SSC dynamics in the world large river-influenced estuaries.

世界各地广泛存在低海拔海岸带(LECZ)。LECZ群落受到海平面上升、风暴潮、湿地退化、地面沉降和洪水的威胁。为了预测长期和短期的洪水事件，科学家需要预测横跨生态、物理、社会和健康科学的过程，以提出适应气候变化需要的新的战略与工程解决方案。本期专刊计划征集具有创新性的跨学科论文，以解决以下问题：（1）人类和社会经济脆弱性之间的联系；（2）公共卫生和安全；（3）经济问题；（4）土地损失；（5）湿地面临的威胁；（6）海岸淹没；（7）管理和政策问题；（8）改善科学家、利益相关者、决策者和沿海居民之间沟通的策略和方法。本专题的主要目标是征集有助于理解风暴潮、水文、城市基础设施、生态系统动力学和人类之间的非线性耦合，并为不同地区提供量身定制的管理和工程解决方案的前沿跨学科论文。我们欢迎能向利益攸关方提供非技术推广途径的原创论文，也欢迎对科学家、建模师、工程师、教育工作者和学术界、地方政府、非政府组织、本地居民和私营部门的利益攸关方建立一个网络。我们希望通过提高认知与技术水平，更好地预测并减轻人类健康、安全和福祉面临的危害，并减少对沿海地区的居民生活、工业发展的有害影响，以提高未来LECZ群落的恢复能力。
我们征集跨学科的创新研究成果，包括通过复杂系统建模的结果来预测未来的沿海威胁、复合洪水及其影响等。风暴潮、暴雨或河流泛滥造成的复合洪水是日益严重的威胁，沿海地区受其影响可能达到一个带来不稳定的临界点。因此我们也需要更多物理的、生态的或是社会经济视角的关于临界点的严谨论文。
我们欢迎区域案例研究、全球预测的投稿，以及基于观测或数值模拟结果，将气候变化对海岸和沿海地区的自然、建筑环境和社会经济影响联系起来的研究。
Low elevation coastal zones (LECZ) are extensive throughout the world. LECZ communities are threatened by inundation from sea level rise, storm surge, wetland degradation, land subsidence and hydrological flooding. To anticipate long and short-term inundation events, scientists must predict processes spanning the ecological, physical, social, and health sciences. Adaptation requires a host of new strategies and engineering solutions. For this special issue, we intend to solicit innovative and interdisciplinary papers to address linkages of (1) human and socioeconomic vulnerabilities; (2) public health and safety; (3) economic concerns; (4) land loss; (5) wetland threats; (6) coastal inundation, (7) management and policy issues and (8) strategies and tools for improving communication among scientists, stakeholders, policy makers and coastal residents. The overarching goal of the proposed issue is to assemble a collection of cutting-edge, interdisciplinary papers that contribute to better understanding of the non-linear couplings among storm surge, hydrology, urban infrastructure, ecosystem dynamics and humanity and offer management and engineering solutions tailored for different regions. Offering approaches for non-technical outreach to stakeholders are welcome. We also welcome ideas for a cyber-network of scientists, modelers, engineers, educators and stakeholders from academia, federal state and local agencies, non-governmental organizations, residents, and the private sector. Our vision is to enhance future resilience of LECZ communities by advancing understandings and approaches to better anticipate and mitigate hazards to human health, safety and welfare and reduce deleterious impacts to coastal residents and industries.
We solicit interdisciplinary and innovative contributions. Complex systems modelling results are urgently needed to anticipate future coastal threats. Papers dealing with compound floods and their impacts, are invited. A major and increasing threat is related to compound flooding by storm surge and torrential rain and/or flooding rivers. Coastal areas may reach a tipping point which may results in destabilization. More rigorous papers on tipping points, which can be physical, ecological, or socioeconomic are needed.
We invite regional case studies and global projections, as well as contributions based on observational or numerically modelled research results linking natural and built environmental and socioeconomic impacts of climate change on coasts and coastal communities.

我们怀着沉痛的心情为 Wim 写下讣告。Wim Salomons 于2022年2月去世，享年77岁。Wim Salomons 出生于1945年5月，1973年在荷兰格罗宁根大学获得博士学位，曾就职于代尔夫特水力研究所、DLO研究组织、农业生物和土壤肥力研究所、阿姆斯特丹自由大学等研究机构。
Wim 是一位杰出的科学家，他极大地影响了人们对不同环境下的沉积物，尤其是污染沉积物的认识。他是一名真正的知识分子，能够以不同的方式看待事物，将不同学科观点融合。作为欧洲沉积物研究网络（SedNet）的推动者之一，他参与编辑了该组织的主要出版物之一（Salomons and Brils, 2004年）。在此，我们向 Wim 对泥沙污染科学和管理做出的贡献致敬。
It is with deep sadness that we write this obituary to Wim Salomons, who passed away in February 2022. Born in May 1945, Wim obtained his PhD in 1973 from the University of Groningen in the Netherlands and he was employed at numerous institutions including Delft Hydraulics, DLO Research Organization, Institute for Agro-Biology and Soil Fertility Research, and the Free University in Amsterdam.
Wim was an outstanding scientist who greatly influenced our understanding of sediment, especially contaminated sediment, in a range of environments. He was a true intellectual, who was able to see things in a different way, and had an ability to integrate ideas from different disciplines. He was also one of the driving forces behind the European Sediment Research Network, SedNet, and co-edited one of the main publications to stem from that organization (Salomons and Brils 2004). Between 2006 and 2010, he was a co-Editor-in-Chief of JSS with Ulrich and Zhihong and contributed positively. Here, we honour Wim’s contribution to sediment–contaminant science and management.

FEC 研究员 Leslie Mabon 最近在英国驻东京大使馆组织的“日本能源的未来挑战”活动上发表了讲话 |
FEC Fellow Leslie Mabon recently spoke at the event 'Future Challenges in Japan on Energy' organised by the British Embassy in Tokyo |
FEC Fellow Leslie Mabon recently spoke at the event 'Future Challenges in Japan on Energy' organised by the British Embassy in Tokyo. Leslie shared some of the initial findings from a British Academy-funded project into just transitions in Japan, on which he is principal investigator. Leslie talked in particular about the need for new coastal net-zero infrastructure in Japan - such as offshore wind and carbon dioxide storage - to be developed in a way that respects social and cultural practices in coastal communities. The project's results also suggest, however, that the energy transition offers an opportunity to build sustainable jobs and economies on Japan's coasts through wind turbine manufacturing, shipbuilding and the hydrogen economy.

From Liana Talaue McManus：
I wish to share two technical reports I co-authored in support of the work of the Caribbean Environment Programme of the UN Environment Programme.
The first is the pioneering State of the Cartagena Convention Area, endorsed by the Conference of Parties in 2019, hence the publication (endorsement) year. It took 2 years to publish it, and it is finally publicly accessible at https://wedocs.unep.org/handle/20.500.11822/36346
The second is the Regional Nutrient Pollution Reduction Strategy and Action Plan for the Wider Caribbean Region. The spatial coverage includes the Cartagena Convention Area and the North Brazil Shel Large Marine Ecosystem. The report has been endorsed by the Conference of Parties in 2021, and the report, in approved format, is available at http://gefcrew.org/carrcu/19IGM/LBSCOP5/Info-Docs/WG.41INF.10Rev.1-en.pdf
I am currently doing a similar Nutrient Pollution Assessment and Reduction Strategy and Action Plan for the East Asian Seas.
