The protection of estuarine intertidal zones is a global hotspot issue. Ocypodoidea crabs are key components of intertidal ecosystems. Understanding the driving mechanisms behind the distribution of Ocypodoidea crabs is of great significance for intertidal conservation. The study, which combined an intertidal zone survey with laboratory salinity selection experiments, investigated the distribution of Ocypodoidea and the environmental factors driving their distribution along the north shore of Hangzhou Bay. The results indicate that we collected a total of 6 Ocypodoidea species, among which Uca arcuata, Macrophthalmus abbreviatus, Macrophthalmus banzai, and Ilyoplax deschampsi were dominant. Under natural conditions, from the bay head to the bay mouth, the four Ocypodoidea crab species transition from freshwater-adapted species (I. deschampsi) to saltwater-adapted species (U. arcuata, M. abbreviatus, M. banzai) along the increasing salinity gradient. Laboratory experiments demonstrated that salinity had an indirect influence on the distribution of I. deschampsi possibly mediated by biological competition. These crabs prefer distinct substrate types (divided into vegetated salt marsh, bare muddy flats and bare sandy flats). Macrophthalmus banzai and M. abbreviatus inhabit bare muddy and sandy flats. Ilyoplax deschampsi adapts to both. Uca arcuata inhabits vegetated salt marsh together with those two flats. Differences in crab substrate preferences and the presence or absence of these substrate types across different sections further drive compositional differences in the Ocypodoidea community. Human activities have altered the distribution patterns of salinity and the aforementioned substrate types along the north shore of Hangzhou Bay, likely driving shifts in the spatial distribution of Ocypodoidea crabs.

河口潮间带的保护是一个全球性的热点问题。蟹科是潮间带生态系统的重要组成部分。了解蟹类分布背后的驱动机制对潮间带保护具有重要意义。采用潮间带调查与室内盐度选择实验相结合的方法，研究了杭州湾北岸鲤科（ocypodo总科）的分布及其环境因素。结果表明，共采集到棘足总科6种，其中以圆角大鼠、短巨眼鼠、斑巨眼鼠和德尚巨眼鼠为优势种。在自然条件下，从湾头到湾口，四种蟹类从淡水适应种（I. deschampsi）到咸水适应种（U. arcuata， M.缩写，M. banzai）沿盐度梯度逐渐增大。室内实验表明，盐度可能通过生物竞争间接影响了德尚水蚤的分布。这些螃蟹喜欢不同的基质类型（分为植被盐沼、裸露的泥地和裸露的沙地）。大眼鼠和短眼鼠栖息在裸露的泥泞和沙质平原上。德尚伊洛普斯适应了这两种情况。乌卡和那两个滩涂一起生活在盐沼里。蟹对基质的偏好差异以及这些基质类型在不同剖面上的存在或不存在，进一步推动了蟹纲群落的组成差异。人类活动改变了杭州湾北岸盐度和上述基质类型的分布格局，可能驱动了蟹类空间分布的变化。

Incorporating near-natural variation of marine environmental variables into experimental designs is becoming imperative to make ecologically relevant inferences about ecophysiological responses to climate global change. Dissolved Oxygen (DO) is among the most important environmental variable in marine ecosystems and fluctuates strongly in coastal habitats, due to physical and biological phenomena. However, many technical challenges are still imposing high-cost equipment to ensure a complete mimicry of DO fluctuations in manipulative experiments. Here, we propose a simple and cost-effective methodology to simulate the oxygen fluctuations in the laboratory through to marine primary producers as source of natural fluctuations. We tested the physiological status (Yield II and F_v/fm) as a proxy of oxygen evolution, and photoprotective responses (phenolic production), as metabolic stress indicator in five different biomasses (200–400–600-800-1000 g; that correspond to 6–12–18-24-30 g l⁻¹, respectively) of the macroalgae Lessonia spicata exposed to 7 days of artificial light (photoperiod of 12:12 h day: night) within replicated aquaria. We showed that each biomass exhibited a unique fully functional oxygen fluctuating profile with different average DO saturations, harmonic oscillations and rates of DO production/consumption. Biomasses <600 g showed no significant changes in the physiological status of macroalgae (Yield II and F_v/fm) and photoprotective responses (phenolic production) during the 7 days experiment, while effects of the environmental stress were found at greater biomasses (800 and 1000 g). We successfully tested a method that can produce daily cycles of DO fluctuations in seawater trough to marine primary producers under controlled environment conditions. Our quantitative method provides cost-effective control the DO fluctuations in experimental set-ups with the use of a primary producers that can be replicated at low cost in virtually any laboratory worldwide using other species of marine algae, representing a highly effective method to control experimental settings that involve testing of fluctuating and ecologically relevant levels of dissolved oxygen.

将海洋环境变量的近自然变化纳入实验设计中，对气候全球变化的生态生理反应做出与生态相关的推断变得势在必行。溶解氧（DO）是海洋生态系统中最重要的环境变量之一，由于物理和生物现象，在沿海生境中波动剧烈。然而，许多技术挑战仍然强加高成本的设备，以确保在操作实验中完全模仿DO波动。在这里，我们提出了一种简单而具有成本效益的方法来模拟实验室中的氧气波动，通过海洋初级生产者作为自然波动的来源。我们测试了5种不同生物量(200-400-600-800-1000 g；（分别对应于6-12-18-24-30 g l−1），即在复制水族箱内暴露于7天的人工光照（光周期为昼夜12:12 h）。我们发现，每种生物量都表现出独特的全功能氧波动曲线，具有不同的平均DO饱和度、谐波振荡和DO生产/消耗速率。在7天的试验中，600 g生物量对大型藻类的生理状态（产量II和Fv/fm）和光保护反应（酚生成）没有显著影响，而在更大生物量（800和1000 g）中发现了环境胁迫的影响。我们成功地测试了一种方法，该方法可以在受控环境条件下向海洋初级生产者产生海水槽中DO波动的每日循环。我们的定量方法提供了成本效益高的控制实验设置中溶解氧波动的方法，使用初级生产者，可以在世界上几乎任何实验室使用其他种类的海洋藻类以低成本复制，这是一种非常有效的方法，可以控制涉及测试波动和生态相关溶解氧水平的实验设置。

Global ocean heat content (GOHC) changes are crucial to understanding climate change, as oceans store about 91 % of the excess heat in the climate system. The thermal expansion of oceans significantly contributed to sea level rise in the twentieth century and will likely remain a major factor in the twenty-first century. This study analyzed decades of data from global ocean reanalysis and satellites, revealing that from 2014 to 2023, the annual rates of increase in GOHC and global mean sea level (GMSL) were 45.2 ± 1.78 MJ/m² and 4.7 ± 0.23 mm, respectively. These rates are 1.7 and 1.8 times higher than those of the previous four decades. Thermal expansion alone accounts for 56 % of the total GMSL rise. A 1 °C increase in global ocean temperature would result in a 0.89-m rise in GMSL due solely to thermal expansion. GOHC variations align with GMSL changes monthly, though a three-month delay is observed in regions such as Southwest China, the Indochinese Peninsula, and the coastal Middle East. Significant increases in both GOHC and GMSL are most evident in the 20°N–40°N and 20°S–40°S regions. Since the late 1980s, greenhouse gas emissions have overtaken solar radiation as the primary driver of ocean temperature increases. Since the 1990s, the Earth's energy imbalance (EEI) has remained positive, with an annual increase of 0.03 ± 0.016 W/m², indicating excess heat accumulation.

全球海洋热含量（GOHC）变化对了解气候变化至关重要，因为海洋储存了气候系统中约91%的多余热量。海洋的热膨胀是20世纪海平面上升的重要原因，在21世纪可能仍然是一个主要因素。本研究分析了全球海洋再分析和卫星数据，发现2014 - 2023年，GOHC和全球平均海平面（GMSL）的年增长率分别为45.2±1.78 MJ/m2和4.7±0.23 mm。这些比率是过去40年的1.7到1.8倍。仅热膨胀一项就占总GMSL上升的56%。全球海洋温度每升高1°C，仅由于热膨胀就会导致全球海平面高度升高0.89米。GOHC的变化与GMSL的月度变化一致，但在中国西南部、印度支那半岛和中东沿海地区观察到三个月的延迟。在20°N - 40°N和20°S - 40°S区域，GOHC和GMSL的显著增加最为明显。自20世纪80年代末以来，温室气体排放已超过太阳辐射，成为海洋温度升高的主要驱动因素。20世纪90年代以来，地球能量不平衡（EEI）持续为正，年增幅为0.03±0.016 W/m2，表明地球存在过剩热量积累。

With the continued growth of the global maritime economy and trade, the shipping industry faces a variety of safety and security challenges. Maritime safety management(MSM) and maritime emergency management(MEM) are complementary to each other, and together they form a comprehensive maritime safety system. The International Maritime Organization (IMO) has established a framework for MEM through a series of conventions. Existing review articles in the field of MSM focus more on the prevention and control of maritime accidents. However, there is a significant lack of systematization for MEM research focusing on the response and disposal of maritime emergencies. To achieve this, this paper first identified 1399 important papers on MEM research from the China National Knowledge Infrastructure (CNKI) and Web of Science (WoS) databases from 2000 to 2024 by screening using PRISMA flow diagram. Second, the knowledge map of MEM research was constructed by using the bibliometric analysis tools CiteSpace and VOSviewer. Then, through the multidimensional analysis of the knowledge map for MEM research, the lineages, themes, hotspots, and trends of MEM research were systematically clarified. Finally, suggestions for the future development of MEM are made from the three dimensions. The systematic review of MEM research in this paper could help researchers to clarify the hotspots and trends for current MEM research, and provide new perspectives and theoretical support for research in this field.

随着全球海洋经济和贸易的持续增长，航运业面临着各种安全与安保挑战。海上安全管理与海上应急管理是相辅相成的，共同构成了一个完整的海上安全体系。国际海事组织（IMO）通过一系列公约建立了MEM的框架。现有的男男性行为领域的综述文章更多地集中在预防和控制海上事故上。然而，对于以海上突发事件的响应和处置为重点的MEM研究，目前明显缺乏系统化。为此，本文首先利用PRISMA流图筛选了2000 - 2024年中国知网（CNKI）和Web of Science （WoS）数据库中关于MEM研究的1399篇重要论文。其次，利用文献计量分析工具CiteSpace和VOSviewer构建了MEM研究的知识图谱。然后，通过对memm研究知识图谱的多维度分析，系统梳理了memm研究的脉络、主题、热点和趋势。最后，从三个维度对MEM的未来发展提出了建议。本文对MEM研究进行系统回顾，有助于厘清当前MEM研究的热点和趋势，为该领域的研究提供新的视角和理论支持。

The purpose of this study is to empirically investigate how climate-related financial policies affect marine living resource performance in order to demonstrate how they contribute to a sustainable blue economy. We use five different indicators to evaluate blue economies' efficiency and sustainability in European regions. These indicators include the value added at the factor costs of small-scale capture fisheries; shellfish aquaculture; freshwater aquaculture; marine aquaculture; and large-scale capture fisheries. The findings of our assessment show how crucial climate-related measures are to increasing the sustainability of the blue economy in the European area between 2010 and 2019. The research findings reveal the varying impacts of climate-related financial policies on blue economy sustainability across different quantiles.

本研究的目的是实证研究与气候相关的金融政策如何影响海洋生物资源绩效，以证明它们如何促进可持续的蓝色经济。我们使用五种不同的指标来评估欧洲地区蓝色经济体的效率和可持续性。这些指标包括小规模捕捞渔业按要素成本计算的增加值；贝类养殖;淡水水产养殖;海洋水产养殖;以及大规模捕捞渔业。我们的评估结果表明，在2010年至2019年期间，与气候相关的措施对于提高欧洲地区蓝色经济的可持续性至关重要。研究结果显示，气候相关金融政策对蓝色经济可持续性的影响在不同分位数之间存在差异。

With rising sea level and increasing typhoon intensity under greenhouse warming, risk of typhoon-related hazards, including strong winds, storm surges and waves in coastal regions, is becoming increasingly severe. Hainan province of China, adjacent to the western North Pacific, is vulnerable to typhoon hazards. In this study, we constructed 65 typhoons using the Jelesnianski model to force the Advanced Circulation (ADCIRC)-Simulating Waves Nearshore (SWAN) coupled model and reproduced typhoon waves and surges, then assessed their extreme values around Hainan under 20-, 50-, and 100-year return periods. Taking Sanya station as an example, we further conducted joint risk analysis via considering bivariate and Trivariate hazard factors. The relative errors of modelled wind speed (V), significant wave height (SWH), and storm surge (S) are less than 10 % compared to in-situ observations. Using the Gumbel function, extreme values of V, SWH, and S under the 100-year return period around Hainan province can exceed 40 m s⁻¹, 15 m, and 2 m. After Kolmogorov test, the Gumbel-Hougaard Copula function was used to estimate bivariate and trivariate joint probability distributions at Sanya station and calculate the “OR” return periods of different joint events. The “OR” return period of three factors at the Sanya station under the 100-year extreme value is 48.79 years, indicating a high probability of simultaneous occurrence on account of their correlation. This study focused on the complex topography surrounding Hainan Island and utilized a coupled model to compensate for the limitation of synchronous observational data in typhoon joint risk analysis.

随着海平面上升和温室效应下台风强度的增加，沿海地区发生强风、风暴潮和海浪等台风相关灾害的风险日益严重。中国海南省毗邻北太平洋西部，容易受到台风灾害的影响。本研究利用Jelesnianski模式强迫高级环流(ADCIRC)-模拟近岸波浪（SWAN）耦合模式构建了65个台风，模拟了台风波浪和风暴潮，评估了它们在20年、50年和100年回归周期下在海南附近的极值。以三亚站为例，进一步结合双因素和三因素进行联合风险分析。模拟的风速(V)、有效波高（SWH）和风暴潮(S)与现场观测值的相对误差小于10%。利用Gumbel函数，海南周边100年回归期V、SWH和S的极值可以超过40 m S−1、15 m和2 m。经过Kolmogorov检验，利用Gumbel-Hougaard Copula函数估计三亚站的二元和三元联合概率分布，并计算不同联合事件的“OR”回归期。在100年极值下，三亚站3个因子的“OR”回归期为48.79年，由于它们之间的相关性，表明它们同时发生的可能性很大。本研究针对海南岛周边复杂地形，利用耦合模型弥补同步观测资料在台风联合风险分析中的局限性。

During October 2024, unprecedented oceanographic conditions were observed around the Oyashio and Coastal Oyashio in the North Pacific Ocean off the southeast coast of Hokkaido, Japan. A very strong anticyclonic mesoscale eddy, the “Kuroshio Warm Core Ring (KWCR)”, detached from the Kuroshio Extension, which had abnormally overshot, and approached the southeast coast of Hokkaido. Extremely large, positive anomalies of temperature and salinity with a maximum of 14.1 °C and 1.61, respectively, were detected on the slope where the Oyashio flows in normal years. Isopycnal surfaces with extremely large downward displacements from their mean positions reached a maximum of 413 dbar. The approach of the KWCR to the coast caused unusual oceanographic conditions on the shelf. Kuroshio Water with salinities ≥33.7 and temperatures ≥5 °C spread from the KWCR and was identified at a regular monitoring station on the shelf for the first time since 1987. The Coastal Oyashio, a nearly stable westward coastal boundary current, disappeared from the western part of the shelf and was replaced by eastward currents parallel to the anticyclonic flows of the KWCR. The intrusion of the Oyashio into the study region weakened in October 2024. However, because a similar tendency of weakening has been apparent since autumn 2019, the weakening of the Oyashio was not attributable solely to the stagnation of the KWCR.

2024年10月，在日本北海道东南海岸外的北太平洋亲潮和沿海亲潮周围观测到前所未有的海洋学条件。一个非常强的反气旋中尺度涡旋“黑潮暖核环”（KWCR）脱离异常过冲的黑潮延伸带，向北海道东南海岸靠近。在正常年份，在大潮流动的斜坡上，检测到温度和盐度的极大正异常，最大异常值分别为14.1°C和1.61°C。从其平均位置向下位移极大的等平面最大可达413 dbar。KWCR靠近海岸造成了大陆架上不寻常的海洋学状况。盐度≥33.7、温度≥5°C的黑潮水来自KWCR，自1987年以来首次在大陆架上的常规监测站被发现。一个几乎稳定的西向海岸边界流——海岸潮从陆架西部消失，取而代之的是平行于KWCR反气旋流的东向流。2024年10月，大潮对研究区的侵入减弱。然而，由于自2019年秋季以来类似的减弱趋势已经很明显，因此大潮的减弱并不仅仅是由于KWCR的停滞。

Jellyfish blooms affect human activities, causing negative socio-economic impacts. Many questions regarding the presence of these invertebrates remain unknown, including when and why they appear. The aim of this study was to unravel when and which environmental drivers drive the arrival of jellyfish to the urban beach of Las Canteras (Canary Islands), by taking advantage of a long-term temporal series on jellyfish stings and semi-qualitative abundances of three jellyfish species (Physalia physalis, Velella velella and Pelagia noctiluca), provided by the Red Cross rescue service. First, we described inter- and intra (seasonal) annual patterns. Then, daily patterns in stings and monthly jellyfish abundances, by means of a model selection strategy, were connected with daily and monthly environmental drivers (zooplankton biomass, Sea Surface Temperature, SST, wind intensity, as well as climatic indices related to El Niño and La Niña events). We detected a strong seasonal trend in the number of jellyfish stings, with larger values in spring and summer relative to autumn and winter. Physalia physalis and Velella velella appeared during winter, which was also revealed by the model selection approach on the effect of environmental predictors (SST, in particular) on their abundances. In contrast, Pelagia noctiluca -the most abundant species - was present all year round, with the summer months as those with the highest abundances. There was a significant correlation between the daily number of stings and the daily presence of Pelagia noctiluca over time. In brief, the occurrence of the three jellyfish species, in the study area, is seasonally partitioned, with SST over time as the most relevant environmental predictor of both the number of stings and the abundances of the three jellyfish species.

水母大量繁殖影响人类活动，造成负面的社会经济影响。关于这些无脊椎动物的存在，许多问题仍然未知，包括它们何时以及为什么出现。本研究的目的是通过利用红十字会救援服务提供的水母蜇伤的长期时间序列和三种水母（Physalia physalis， Velella Velella和Pelagia noctiluca）的半定性丰度，揭示水母何时以及哪些环境驱动因素促使水母到达Las Canteras（加那利群岛）的城市海滩。首先，我们描述了年间和年内（季节）的模式。然后，通过模型选择策略，将蜇伤的日模式和水母的月丰度与日和月环境驱动因素（浮游动物生物量、海面温度、海温、风强度以及与El Niño和La Niña事件相关的气候指数）联系起来。海蜇蜇伤数量有明显的季节变化趋势，春季和夏季的蜇伤数量大于秋季和冬季。Physalia physalis和Velella Velella在冬季出现，这也揭示了环境预测因子（尤其是海温）对其丰度影响的模式选择方法。相比之下，最丰富的物种夜光Pelagia noctiluca全年都有，夏季是丰度最高的月份。随着时间的推移，日蜇伤次数与夜蛾日存在量之间存在显著的相关性。简而言之，这三种水母在研究区域的发生是季节性的，海温随时间的变化是三种水母蜇伤数量和丰度的最相关环境预测因子。

The COVID-19 pandemic has highlighted the urgent need for policy-driven improvements in inspection protocols at international ports, particularly for refrigerated goods, which are vulnerable to virus transmission through external packaging. This study addresses the increased inspection demands during health emergencies, where inspection rates may rise from 10 % to 100 %, requiring a combination of advanced scanning technologies and meticulous manual checks. Such escalated inspection efforts inevitably lead to substantial logistical backlogs, exacerbating port congestion, prolonging dwell times, and increasing the risk of cargo spoilage due to temperature fluctuations. This study introduces a sophisticated scheduling model for container inspection operations, designed to align with current health policy frameworks. The model incorporates specific time windows and temperature controls to mitigate the risks associated with extended storage times. Furthermore, it examines the policy implications of varying the deployment of Automated Guided Vehicles (AGVs) and inspection platforms to optimize throughput and minimize operational delays during crises. Empirical results suggest that prioritizing the expansion of inspection infrastructure, coupled with strategic AGV adjustments, significantly enhances operational efficiency and ensures compliance with health policies during emergencies.

2019冠状病毒病大流行突出表明，迫切需要在政策驱动下改进国际港口的检查规程，特别是对冷藏货物的检查规程，因为冷藏货物很容易通过外部包装传播病毒。本研究解决了突发卫生事件中日益增加的检查需求，检查率可能从10%上升到100%，需要先进的扫描技术和细致的人工检查相结合。这种加强检查的努力不可避免地导致大量的物流积压，加剧港口拥堵，延长停留时间，并增加因温度波动而导致货物损坏的风险。本研究为集装箱检查操作引入了一个复杂的调度模型，旨在与当前的卫生政策框架保持一致。该模型结合了特定的时间窗口和温度控制，以减轻与延长储存时间相关的风险。此外，它还研究了自动引导车辆（agv）和检查平台的不同部署对政策的影响，以优化吞吐量并最大限度地减少危机期间的操作延迟。实证结果表明，优先扩大检查基础设施，加上战略性调整AGV，可显着提高操作效率，并确保在紧急情况下遵守卫生政策。

Reefs formed by the tube-building polychaete Sabellaria spinulosa are a well-known and widely recognized example of biogenic reef structures that used to occur in the subtidal zone of the Wadden Sea. We derived their optimal habitat requirements and identified a sublittoral rock revetment in the western Wadden Sea as a potential habitat. We mapped the seafloor properties and sampled hard substrate fauna to assess the suitability for Sabellaria. The sublittoral rock revetment lying at water depths of 3.5 m to 14 m below sea level shows a gully slope with a mixture of rocks and sand. The artificial reef has riprap up to 0.5 m in diameter, stretches over 6 km length and has a surface area of 42.5 ha. In total, 80 taxa of fauna were found in five scrape samples of 0.05 m² each of which 62 were hierarchically unique taxa. Median species richness was 33 and median Shannon-Wiener diversity was 1.70. One individual of the reef-building polychaete Sabellaria spinulosa was found in one of the samples. This is the third record in the Dutch Wadden Sea since 1955. These findings suggest that this sublittoral rock revetment in the western Wadden Sea has suitable habitat conditions for the tube-building polychaete Sabellaria spinulosa.

由管状多毛目沙棘藻（Sabellaria spinulosa）形成的珊瑚礁是众所周知、广为人知的生物礁结构，曾经出现在瓦登海的潮下带。我们得出了它们的最佳栖息地要求，并将瓦登海西部的一个滨下岩石护岸确定为潜在的栖息地。我们绘制了海底属性图，并对硬底质动物群进行了取样，以评估沙贝藻的适宜性。位于海平面以下 3.5 米至 14 米水深处的沿岸岩石护岸显示出岩石和沙子混合的沟壑斜坡。人工礁石的护坡直径达 0.5 米，长 6 公里，面积 42.5 公顷。在 5 个面积各为 0.05 平方米的刮取样本中，共发现了 80 个动物分类群，其中 62 个为层次独特的分类群。物种丰富度中位数为 33，香农-维纳多样性中位数为 1.70。其中一个样本中发现了造礁多毛类动物 Sabellaria spinulosa 的一个个体。这是自 1955 年以来荷兰瓦登海的第三个记录。这些研究结果表明，瓦登海西部的滨海岩石护岸具有适合造管多毛类沙贝藻（Sabellaria spinulosa）栖息的条件。
