China's offshore wind power industry is advancing toward a digital transformation, and its development is considered a crucial strategic pillar of China's energy structure transformation. Facing challenges such as high costs, technical difficulties, lack of industry standards, insufficient industrial economies of scale, and even ecological threats, China's offshore wind power industry in the new period urgently requires innovative paths for further development. Driven by policy guidance and market demand, many enterprises have embarked on digital upgrading by introducing digital technology into their business processes, thus achieving a more efficient and intelligent production management mode to enhance industry competitiveness. However, due to the inherent peculiarities of the offshore wind power industry, its implementation of digital technology faces certain technical difficulties and systemic risks. This study presents a case study of Mingyang Smart Energy and related organizations conducted using in-depth interviews, and focuses on the practical circumstances of China's offshore wind power industry undergoing digital transformation. This study also applies the grounded theory to analyze the driving factors and mechanisms of digital transformation and provides an in-depth discussion of the characteristics of different stages of the transformation, including digital technology function leap, management and platform construction, as well as digital operation and value creation. The study results can enrich the theoretical study of digital transformation and provide practical guidance for the offshore wind power industry to achieve intelligent, efficient, and sustainable development.

Large-scale estimations of wave periods are desired for wave energy assessment, ocean engineering, and wave climate research. Long-term global wave data from satellite altimeters are routinely applied to the estimations. However, this is challenged by uncertainties in wave-period models (WPMs), inaccuracies in data, and simplifications in modeling. Additionally, there exists a gap in the comprehensive examination of the variational mechanisms governing wave periods or model performances. As an effort to address them, we innovate a macroscale regionalized ensemble wave-period modeling (MREWPM) method by optimizing four wave-period models, driven by enhanced altimeter-based REWS (regionalized ensemble wave simulation) estimates of wave heights and wind speeds, within a regionalization framework in macroscale water environments. Results show that MREWPM driven by REWS dataset outperforms existing methods and performs better at larger scales (e.g., in eliminating local-scale overestimation). WPMs are more accurate over remote, deep, and windy regions in cool seasons under metrics-, scale- and data-dependent variations of performances with driving factors (mainly geographical features). This study serves as a foundational contribution towards the enhancement of wave-period simulations, the advancement of understanding wave-period dynamics, and the scientific evaluation of wave energy at macroscales.

波浪能评估、海洋工程和波浪气候研究需要大规模的波浪周期估算。卫星测高仪提供的长期全球波浪数据通常用于估算。然而，波浪周期模型（WPMs）的不确定性、数据的不准确性以及建模的简化都对这一工作提出了挑战。此外，对波浪周期或模型性能的变异机制的全面研究也存在空白。为了解决这些问题，我们创新了一种宏观区域化集合波浪周期建模（MREWPM）方法，在宏观水域环境的区域化框架内，以基于高度计的增强型 REWS（区域化集合波浪模拟）波高和风速估算为驱动，优化了四个波浪周期模型。结果表明，由 REWS 数据集驱动的 MREWPM 优于现有方法，在更大尺度上表现更好（例如，在消除局部尺度高估方面）。在度量、尺度和数据随驱动因素（主要是地理特征）而变化的情况下，WPM 在冷季的偏远、纵深和多风地区更为准确。这项研究为加强波浪周期模拟、促进对波浪周期动力学的理解以及在宏观尺度上对波浪能进行科学评估做出了基础性贡献。

Globally, the demand for shipping and construction-grade sand is increasing at a very high rate; many large estuaries are affected by large-scale dredging, which dramatically impacts estuarine hydrodynamics and geomorphology. Lingdingyang Estuary (LE) has been subjected to large-scale sand mining in recent decades with scattered deep mined pits in the middle shoal. Based on a state-of-the-art modeling tool (TELEMAC), the long-term morphologic evolution of the LE in 1998–2015 and 2016–2021 was reproduced to explain dredging-induced bathymetric changes. Then, the influences of massive dredging on geomorphic evolution were mechanistically analyzed. Finally, geomorphic restoration of the sand dredged pits in the Middle Shoal was evaluated using the long-term morphologic model. Large-scale sand mining changed the sedimentation condition of the Middle Shoal from a slight net deposition pattern to a net erosion pattern in 2012–2015. Overall, both channel dredging and sand mining significantly increased erosion in the inner LE (ILE) from 1998 to 2015; sand mining in 2012–2015 contributed 64% for these erosion, whereas channel dredging accounted for 28% in 1998–2012. In contrast, both channel dredging and sand mining increased deposition in the outer LE (OLE) from 1998 to 2015; sand mining in 2012–2015 contributed 44% for these deposition, whereas channel dredging accounted for 55% in 1998–2012. Strengthened tidal forcing, induced by massive dredging in the ILE from 1998 to 2015, was the dominant factor driving sediment entrapment in the ILE (around huge sand pits in the Middle Shoal) during this period. Additionally, channel dredging induced an increase in flow diversion rate in the Western Channel, which led to sediment transport and deposition in the OLE; it also supported sedimentation in the transition zone between the Middle Shoal and Western Channel. Finally, massive sand mining induced variations in geomorphology in the Middle Shoal from 2016 to 2021 that will require ≥50 years to recover under natural conditions; by 2100, the morphologies of these sand dredged pits in the Middle Shoal are not expected to be restored into their morphologies in 2012. The results of this study comprehensively elucidate the responses of long-term estuarine hydrodynamics and morphology to dredging and provide scientific basis for estuarine management.

在全球范围内，航运和建筑用砂的需求量正以极高的速度增长；许多大型河口都受到了大规模挖沙活动的影响，这对河口的水动力和地貌造成了极大的冲击。伶仃洋河口（LE）近几十年来一直受到大规模采砂的影响，中间滩涂有零星的深采坑。基于最先进的建模工具（TELEMAC），再现了伶仃洋河口 1998-2015 年和 2016-2021 年的长期形态演变，以解释疏浚引起的水深变化。然后，从机理上分析了大规模疏浚对地貌演变的影响。最后，利用长期形态模型评估了中浅滩挖沙坑的地貌恢复情况。在 2012-2015 年期间，大规模采砂改变了中浅滩的沉积状况，从轻微的净沉积模式变为净侵蚀模式。总体而言，从 1998 年到 2015 年，航道疏浚和采砂都显著增加了内 LE（ILE）的侵蚀；2012-2015 年采砂造成了 64% 的侵蚀，而 1998-2012 年航道疏浚造成了 28% 的侵蚀。与此相反，1998 年至 2015 年期间，航道疏浚和采砂都增加了外侧河谷（OLE）的沉积；2012 年至 2015 年期间的采砂占这些沉积的 44%，而 1998 年至 2012 年期间的航道疏浚占 55%。1998 年至 2015 年期间在 ILE 进行的大规模疏浚导致潮汐作用加强，是这一时期造成 ILE（中浅滩巨大沙坑周围）沉积物夹带的主要因素。此外，航道疏浚导致西航道的水流分流率增加，从而导致沉积物在 OLE 中迁移和沉积；它还支持了中浅滩和西航道之间过渡带的沉积作用。最后，从 2016 年到 2021 年，大规模采砂引起了中浅滩地貌的变化，需要≥50 年的时间才能在自然条件下恢复；到 2100 年，中浅滩这些挖沙坑的形态预计无法恢复到 2012 年的形态。该研究结果全面阐明了河口水动力和形态对疏浚的长期响应，为河口管理提供了科学依据。

In the current context of climate and anthropogenic change, assessing the adaptive capacity of coastal communities, i.e., their ability to adapt, navigate and/or recover from the impacts of change is key in coastal management and decision-making processes. Framing in adaptive capacity assessments (i.e., what is highlighted) influences how coastal communities’ adaptive capacity is perceived and understood, carrying profound ethical and political implications for governance. The significance of framing within assessments of adaptive capacity has been acknowledged, yet limited research delves into the dynamics of this process, particularly within coastal-social ecological settings. Through a systematic literature review, we address this knowledge gap by exploring how scholarly assessments frame adaptive capacity in social-ecological systems and analyzing their potential implications in coastal adaptation governance. We focus on adaptive capacity assessments using indicators, given their prominence as a frequently employed methodology by policy makers. Our results reveal that assessments are predominately framed under vulnerability frameworks, focusing on how adaptive capacity moderates the impact of climate-related variability using single-level data from individuals or households. Typically, these assessments rely on attributes related to socio-economic factors, access to assets and livelihood diversity to assess present adaptive capacity, with researchers and their paradigms playing a significant role in framing these assessments. We propose that this prevailing perspective may not support coastal communities in meeting the complex challenges they are facing. By providing this comprehensive review on the scientific framing of adaptive capacity assessments in coastal social-ecological systems, we contribute towards advancing frame-reflective adaptive capacity research.

在当前气候和人为变化的背景下，评估沿海社区的适应能力，即其适应、驾驭和/ 或从变化的影响中恢复的能力，是沿海管理和决策过程的关键。适应能力评估的框架（即强调什么）会影响人们对沿岸社区适应能力的看法和理解，对治理工作产生深远的伦理和政治影响。框架在适应能力评估中的重要性已得到公认，但对这一过程的动态研究却很有限，尤其是在沿海社会生态环境中。通过系统的文献综述，我们探讨了学术评估如何构建社会生态系统的适应能力框架，并分析了其对沿岸适应治理的潜在影响，从而填补了这一知识空白。鉴于指标是决策者经常使用的方法，我们重点关注使用指标进行的适应能力评估。我们的研究结果表明，评估主要是在脆弱性框架下进行的，重点关注适应能力如何利用来自个人或家庭的单层次数据来缓和气候相关变异性的影响。通常情况下，这些评估依赖于与社会经济因素、资产获取途径和生计多样性相关的属性来评估当前的适应能力，研究人员及其范式在这些评估的框架中发挥着重要作用。我们认为，这种主流观点可能无法帮助沿海社区应对他们所面临的复杂挑战。通过对沿海社会生态系统适应能力评估的科学框架进行全面审查，我们为推动框架反思型适应能力研究做出了贡献。

Although nature-based and hybrid (i.e., a combination of hard and nature-based) solutions provide well-documented benefits to both the environment and people living nearby, they cannot be implemented in all coastal zones. Thus, the selection process of coastal protection structures (CPSs) requires an in-depth and comprehensible assessment with an effective and robust decision-support framework. Existing frameworks in the literature, however, do not focus on the selection of nature-based solutions and environmental and social factors were not considered thoroughly in these frameworks. In this respect, this research aims to develop a decision-support model that guides decision-makers in selecting the most appropriate and sustainable CPSs. The framework was designed in a way that includes a variety of environmental and social factors along with economic and technical aspects. Then, fuzzy AHP and TOPSIS analyses were conducted to determine the relative importance of the selection factors and to select the most appropriate CPS. Factors such as sediment dynamics, geotechnical issues, construction cost, transportation and navigation effects, and technological know-how were among the top-rated factors. TOPSIS analysis results revealed that mangrove forests and artificial reefs were the top two most sustainable CPSs. The proposed framework can minimize the social and environmental impacts of CPSs and expedite the green transition in the coastal environment.

虽然以自然为基础的解决方案和混合解决方案（即硬性和自然相结合的解决方案）为环境和附近居民带来了有据可查的好处，但它们不可能在所有沿岸地区实施。因此，在选择海岸保护结构（CPS）的过程中，需要通过有效和强大的决策支持框架进行深入和全面的评估。然而，文献中的现有框架并不关注基于自然的解决方案的选择，而且这些框架也没有全面考虑环境和社会因素。为此，本研究旨在开发一个决策支持模型，指导决策者选择最合适、最可持续的 CPS。该框架的设计方式包括各种环境和社会因素以及经济和技术方面。然后，进行模糊 AHP 和 TOPSIS 分析，以确定选择因素的相对重要性，并选择最合适的 CPS。沉积物动力学、岩土工程问题、建筑成本、运输和航行影响以及技术诀窍等因素被列为最重要的因素。TOPSIS 分析结果显示，红树林和人工鱼礁是最具可持续发展性的 CPS 的前两名。建议的框架可以最大限度地减少 CPS 对社会和环境的影响，加快沿海环境的绿色转型。

Network analysis concepts and tools are being increasingly applied to Social-ecological systems (SES) in human-environment and sustainability sciences. In this study, we used the Gao metric (βeff) to measure the resilience of networks in small-scale fisheries (SSF) in the Paranaguá Estuarine Complex (PEC). The purpose was to evaluate the variations and trends in network resilience across eight hydrological sectors of the PEC during different seasons. Our analysis revealed that the βeff metric varied significantly across the eight SES sectors, suggesting that resilience is not uniformly distributed. Notably, the sectors located internally the estuary exhibited lower resilience values than the others. The average trophic level of the fishery catches was the higher hierarchical position variable that most affected the network topological metrics, followed by variables magnitude of conflicts, water and sediment quality, and rainfall. Our hydrodynamic sectorization, reflecting ecological and social interactions, enabled us to identify distinct interaction networks within the PEC. This shows the complexity of managing these SES to ensure the sustainability and resilience of the system. While other variables and spatial and temporal scales could lead to different estimates and relationships, our findings shed light on the importance of resilience quantification and the interaction networks within SES to manage them effectively.

网络分析概念和工具正越来越多地应用于人类-环境和可持续性科学中的社会-生态系统（SES）。在本研究中，我们使用 Gao 指标（βeff）来衡量巴拉那瓜河口综合体（PEC）小型渔业（SSF）网络的复原力。目的是评估巴拉那瓜河口综合体八个水文区域在不同季节网络复原力的变化和趋势。我们的分析表明，βeff 指标在八个 SES 区域之间存在显著差异，表明恢复力并非均匀分布。值得注意的是，位于河口内部的扇形区的恢复力值低于其他扇形区。渔业渔获量的平均营养级是对网络拓扑指标影响最大的高分层位置变量，其次是冲突程度、水质和沉积物质量以及降雨量等变量。我们的水动力分区反映了生态和社会互动，使我们能够识别 PEC 内不同的互动网络。这显示了管理这些生态系统和环境以确保系统可持续性和恢复力的复杂性。虽然其他变量和时空尺度可能导致不同的估计值和关系，但我们的研究结果阐明了复原力量化和生态系统服务内部互动网络对有效管理这些系统的重要性。

This study assesses the vulnerability of the Spanish coastline—a major global tourism destination—to ground movements, providing for the first time initial estimates of the potential socio-economic impact of this phenomenon in this highly strategic territory. Using Interferometric Synthetic Aperture Radar (InSAR) data from the European Ground Motion Service (EGMS), an InSAR-based service developed under the Copernicus initiative, we evaluated the coastline's exposure to natural and human-induced ground movements, and their potential impacts on the road network, buildings, and population. Utilizing a suite of post-processing tools including ADAfinder, we identified a series of Active Deformation Areas (ADAs) and classified them based on their prevailing movement (vertical or horizontal) and displacement rate. As a result, a dataset consisting of 9010 ADAs spread across Spain's 805 coastal municipalities was generated, with 1916 ADAs affecting roadways and 2596 affecting buildings. Most ADAs exhibited predominant vertical movement, primarily associated with land subsidence, although ADAs exhibiting horizontal movement, mainly linked to landslides, were also significant. The majority of ADAs showed moderate to low displacement rates (<25 mm/yr). We calculated a potential economic impact (in 2021€ values) of €19,428.4 million, with €1716.4 million attributed to the road network and €17,712.0 million to buildings. Additionally, we identified a total of 134,236 people potentially vulnerable to these processes. Results highlight both a higher exposure of Spain's Mediterranean coast compared to the Atlantic coast and a higher exposure of the Canary archipelago compared to the Balearic Islands—with the most vulnerable regions being Andalusia and Region of Murcia. This research underscores the potential of the EGMS for conducting both preliminary population exposure analyses and preventive risk assessments to mitigate road and building damage.

本研究评估了西班牙海岸线--全球主要旅游目的地--易受地动影响的程度，首次对这一现象在这一具有高度战略意义的地区可能造成的社会经济影响进行了初步估算。欧洲地动服务（EGMS）是哥白尼计划下开发的一项基于 InSAR 的服务，我们利用欧洲地动服务的干涉合成孔径雷达（InSAR）数据，评估了海岸线受自然和人为地动影响的程度，及其对道路网、建筑物和人口的潜在影响。利用包括 ADAfinder 在内的一套后处理工具，我们确定了一系列活动形变区 (ADA)，并根据其主要运动（垂直或水平）和位移率对其进行了分类。因此，我们生成了一个数据集，其中包括分布在西班牙 805 个沿海城市的 9010 个活动变形区，其中影响道路的活动变形区有 1916 个，影响建筑物的活动变形区有 2596 个。大多数 ADA 主要表现为垂直移动，主要与地面沉降有关，但也有一些 ADA 表现为水平移动，主要与山体滑坡有关。大多数自动退化评估显示出中等至较低的位移率（25 毫米/年）。我们计算出的潜在经济影响（按 2021 欧元价值计算）为 194.284 亿欧元，其中 1.7164 亿欧元用于道路网络，177.12 亿欧元用于建筑物。此外，我们还确定了 134 236 人可能会受到这些过程的影响。研究结果表明，与大西洋沿岸相比，西班牙地中海沿岸的受影响程度更高；与巴利阿里群岛相比，加那利群岛的受影响程度更高，其中最易受影响的地区是安达卢西亚和穆尔西亚地区。这项研究强调了 EGMS 在进行初步人口暴露分析和预防性风险评估以减少道路和建筑物损坏方面的潜力。

Regulatory frameworks and management systems are key determining the resilience of small-scale fishing communities to climate change, as they can either enhance or hinder the ability of fishers to sustain their livelihoods and well-being. In Chile, the fishing sector holds significant economic and social importance. The management of specific resources has evolved with the introduction of territorial user rights, which have overlapped with existing traditional and customary fishing communities. Caleta San Pedro (CSP) is one of those traditional communities with a rich legacy dating back to the mid-1800s that since 1997, has operated under a spatial property rights system (AMERB) granted to a neighboring community who hold the official property rights. In this study, we focused on understanding the extent to which property rights, operating alongside customary rules at CSP, can confer social climate resilience. Through the application of face-to face semi-structured questionnaires to 48 fishers, we investigated a range of social factors that are theoretically linked to foster climate resilience in fishing communities (i.e., fisher mobility, resource stewardship). Fishers’ responses were categorized in 23 indicators that relate to the different resilience factors, both at the individual (fisher) and the collective (CSP guild) levels. Our study reveals some mismatches in resilience indicators between the individual and collective scales partly due to differing capacities within the embedded regulatory system (e.g. long-term stewardship is high for the individual fishers however lower at the collective scale). However, our findings also illustrate the potential of the system to promote resilience by involving fishers more extensively in decision-making processes, addressing existing inequalities, and implementing adaptive management strategies. Results can shed some light on how resilience may be fostered in similar customary fishing communities embedded in property rights systems elsewhere.

监管框架和管理系统是决定小型渔业社区抵御气候变化能力的关键，因为它们可以增强或阻碍渔民维持生计和福祉的能力。在智利，渔业具有重要的经济和社会意义。随着领土使用权的引入，特定资源的管理发生了变化，与现有的传统和习惯捕鱼社区重叠。卡莱塔圣佩德罗（Caleta San Pedro，CSP）就是这样一个传统社区，其丰富的历史可追溯到 1800 年代中期，自 1997 年以来，该社区一直在空间产权制度（AMERB）下运作，该制度授予了拥有官方产权的邻近社区。在这项研究中，我们重点了解产权与 CSP 的习惯规则一起运作时，能在多大程度上赋予社会气候复原力。通过对 48 名渔民进行面对面的半结构式问卷调查，我们调查了一系列理论上与促进渔业社区气候复原力相关的社会因素（即渔民流动性、资源管理）。渔民的回答被归类为 23 项指标，这些指标涉及个人（渔民）和集体（CSP 行会）层面的不同复原力因素。我们的研究揭示了个体和集体尺度之间复原力指标的一些不匹配，部分原因是嵌入式监管系统内的能力不同（例如，个体渔民的长期管理能力较高，但集体尺度较低）。不过，我们的研究结果也说明，通过让渔民更广泛地参与决策过程、解决现有的不平等问题以及实施适应性管理战略，该系统具有促进复原力的潜力。这些结果可以为其他地方嵌入产权制度的类似传统渔业社区如何提高复原力提供一些启示。

Harmful algal blooms (HABs) are a global phenomenon occurring in a range of aquatic environments, with the potential to have diverse environmental, social and economic impacts. There is growing interest in the human dimensions of HABs particularly as a result of the increased occurrence of HABs linked to anthropogenic activities. However, to date this has focused more on the economic and health implications of HABs events rather than broader human dimensions. This paper presents a series of research priorities that could strengthen social science research on HABs, highlighting topics related to public awareness and attitudes, community science, governance and co-development of solutions, links to the blue economy agenda, impacts on marine culture and heritage, and impacts on health and wellbeing. Finally, the paper presents a series of recommendations developing a transdisciplinary research agenda in order for the ongoing challenges of HABs to be addressed.

有害藻华（HABs）是一种全球性现象，发生在各种水生环境中，可能对环境、社会和经济产生不同的影响。人们对有害藻华的人为因素越来越感兴趣，特别是因为与人为活动有关的有害藻华发生率越来越高。然而，迄今为止，人们更多关注的是有害藻华对经济和健康的影响，而不是更广泛的人文因素。本文提出了一系列可以加强有害藻华社会科学研究的优先研究事项，强调了与公众意识和态度、社区科学、治理和共同制定解决方案、与蓝色经济议程的联系、对海洋文化和遗产的影响以及对健康和福祉的影响有关的主题。最后，本文提出了一系列制定跨学科研究议程的建议，以应对有害藻类繁殖的持续挑战。

Integrated Mangrove Aquaculture (IMA) has the potential to simultaneously address the challenges of environmental degradation arising from conventional shrimp production, the expected impacts of climate change, and the growing global demand for shrimp. These challenges affect coastal livelihoods in Satkhira and Khulna districts of Bangladesh. However, IMA adoption in coastal Bangladesh so far remains low. This study explores the factors that influence IMA adoption by extensive smallholder shrimp farmers in Bangladesh using a questionnaire-based survey of 128 farmers. We identified potential drivers of adoption by combining exploratory data analysis and a logit regression analysis. Key findings were that lack of adoption appeared to be mainly attributed to a lack of awareness of IMA (65% of non-adopters were not aware of the existence of IMA), as well as a lack of trust in own required management skills and technical know-how. On the other hand, positive evaluation of IMA benefits and its main use as a risk mitigating strategy were the main enablers. The logit regression analysis indicated that perceived suitability of the pond to integrate IMA and availability of technical assistance were the factors most important to adoption, explaining respectively 30% and 26% of adoption. To enhance adoption of IMA and reduce the need for new pond excavation in mangrove stands, tailored technical training and social learning opportunities are required to increase awareness of IMA and its potential benefits, as well as for effective IMA management. Additionally, the development of new market opportunities for novel mangrove products is vital to foster incentives for adoption. Further work is needed on how to maximize the potential of IMA by thorough study of its various implementation options.

红树林综合水产养殖（IMA）具有同时应对传统对虾生产造成的环境退化、气候变化的预期影响以及全球对虾需求增长等挑战的潜力。这些挑战影响着孟加拉国萨特赫拉和库尔纳地区的沿海生计。然而，迄今为止，IMA 在孟加拉国沿海地区的采用率仍然很低。本研究通过对 128 位养殖户进行问卷调查，探讨了影响孟加拉国小农广泛采用 IMA 的因素。我们结合探索性数据分析和对数回归分析，确定了采用的潜在驱动因素。主要发现是，未采用的主要原因似乎是对 IMA 缺乏认识（65% 的未采用者不知道 IMA 的存在），以及对自身所需的管理技能和技术诀窍缺乏信任。另一方面，积极评价 IMA 的益处及其作为风险缓解战略的主要用途是主要的促进因素。对数回归分析表明，认为池塘适合采用综合管理和技术援助是采用综合管理和技术援助的最重要因素，分别占采用率的 30% 和 26%。为提高 IMA 的采用率并减少在红树林中挖掘新池塘的需求，需要提供有针对性的技术培训和社会学习机会，以提高对 IMA 及其潜在效益的认识，并进行有效的 IMA 管理。此外，为红树林新产品开发新的市场机会对于鼓励采用至关重要。还需要进一步开展工作，通过深入研究各种实施方案，最大限度地发挥 IMA 的潜力。
