摘要：浮游植物群落因环境条件而发生变化，可能通过改变营养相互作用来影响浮游动物。在白令海，近几十年来的温暖和寒冷节段与浮游动物和鱼类群落结构的变化相关。根据总叶绿素 a (Chl a) 浓度模式将这些趋势与初级生产者联系起来的尝试尚未成功。使用叶绿素 a 作为食物供应量的替代指标，忽略了浮游植物群落变化的潜在后果，浮游植物群落的细胞形状、大小和生化成分多种多样，对初级消费者饮食的贡献并不相同。 我们分析了 2003 年至 2018 年与环境变量相关的浮游植物的大小结构和分类组成，并研究了对 0 龄狭鳕饮食重要的两个桡足类属（Calanus 和 Pseudocalanus）的丰度之间的关系。确定了三个不同的环境节：Warm1（2003-2005），具有高温和盐度以及低营养浓度，有利于鞭毛虫、纤毛虫和甲藻的优势，以及Calanus的低丰度；寒冷（2006-2012），低温、盐度低，氮浓度高，有利于隐生植物红单胞菌和小中心硅藻的生长，以及哲水藻丰度高； Warm2（2014-2018）具有高温、盐度和营养物（包括高SiO 4 ），支持高丰度的细长杆状硅藻和低丰度的哲水藻。 哲水蚤丰度（2003-2018）与大型（> 10 μm）浮游植物的生物量呈显着负相关，与类群细柱藻、角藻和网藻呈中强负相关，与红单胞菌呈强正相关，突出了浮游植物和浮游动物群落结构之间对环境节交替的响应的联系。
Abstract: Phytoplankton communities change in response to environmental conditions, potentially impacting zooplankton through altered trophic interactions. In the Bering Sea, warm and cold stanzas in recent decades correlated with changes in community structure of zooplankton and fish. Attempts to link these trends to primary producers based on patterns in total chlorophyll a (Chl a ) concentration have been unsuccessful. Using Chl a as a proxy for food availability ignores potential consequences of community shifts in phytoplankton, which span a vast range of cell shapes, sizes, and biochemical composition that do not contribute equally to primary consumer diets. We analyzed size structure and taxonomic composition of phytoplankton in relation to environmental variables from 2003 to 2018 and examined relationships to the abundance of two copepod genera ( Calanus and Pseudocalanus ) important to age‐0 pollock diets. Three distinct environmental stanzas were identified: Warm1 (2003–2005) with high temperature and salinity and low nutrient concentrations favoring dominance of flagellates, ciliates, and dinoflagellates, and low abundances of Calanus ; Cold (2006–2012) with low temperature and salinity and high nitrogen concentrations favoring the cryptophyte Rhodomonas and small centric diatoms, and high Calanus abundances; and Warm2 (2014–2018) with high temperature, salinity, and nutrients (including high SiO 4 ), supporting high abundances of elongated rod‐like diatoms, and low abundances of Calanus . Calanus abundance (2003–2018) was significantly negatively correlated with biomass of large (> 10 μm) phytoplankton, with moderate‐strong negative correlations with the taxa Leptocylindrus , Ceratium , and Dictyocha , and strong positive correlations with Rhodomonas , highlighting links between phytoplankton and zooplankton community structure in response to alternating environmental stanzas.

摘要：海洋热浪的频率和严重程度不断升级是大规模珊瑚白化的驱动因素，因此需要快速减少排放并开发可扩展的干预工具。遮蔽珊瑚以减少辐照压力是一种很有前景的方法，但大多数研究都集中在静态结构上，很少涉及恢复动态。在这里，我们测试了实验室规模的海水雾化系统在模拟热/光应力和恢复实验期间作为遮蔽干预的功效。正交设计具有两个温度水平（对照 (26. 5 °C) 与收集地点的热应激 ((MMM)，29. 1 + 3. 7 °C) 和两种光照处理（雾化，33. 3% 遮光 ± 6. 使用 46 SD 每天 6 小时与非雾化）来测试 Acropora hyacinthus 和 Pocillopora damicornis 在 13 天的热应激（3 °C 周）和 24 天的恢复期中的反应。海水雾的可变遮荫将热应激的风信子的死亡风险降低了 55%。在没有雾的热应激处理下，白角鳖只发生了两次死亡。雾会降低两个物种的白度百分比并改善 Fv/Fm，从 0. 84 °C 周开始，效果在 3 °C 周附近达到峰值。恢复期间的雾化不会抑制珊瑚恢复，但提供了一些额外的好处，包括增加 Fv/Fm 和降低过氧化氢酶活性。海水雾不仅可以在热应激较高时延迟/减少白化，还可以促进珊瑚的恢复和应激后修复过程。 为了推动海水雾化成为一种实用的珊瑚礁干预工具，工程进步应伴随着现场试验，捕捉复杂的珊瑚-环境相互作用并评估整个生态系统的反应。
Abstract: The escalating frequency and severity of marine heatwaves are driving factors behind mass coral bleaching, necessitating both rapid emission reductions and the development of scalable intervention tools. Shading coral to reduce irradiance stress is a promising approach, yet most studies focus on static structures, and few include recovery dynamics. Here, we tested the efficacy of a laboratory-scale seawater fogging system as a shading intervention during a simulated thermal/light stress and recovery experiment. An orthogonal design with two temperature levels (control (26.5 °C) vs heat-stressed ((MMM) at the collection site, 29.1 + 3.7 °C) and two light treatments (fogged, 33.3% shading ± 6.46 SD for 6 h daily vs non-fogged) was used to test the response of Acropora hyacinthus and Pocillopora damicornis over 13 days of thermal stress (3 °C-weeks) followed by a 24-day recovery period. Variable shading from seawater fog reduced mortality risk in heat-stressed A. hyacinthus by 55%. Only two mortalities occurred in P. damicornis , both in the heat-stressed treatment without fog. Fog lowered per cent whiteness and improved Fv/Fm in both species, starting at 0.84 °C-weeks, with the effects peaking near 3 °C-weeks. Fogging during the recovery period did not inhibit coral recovery but provided some additional benefits, including increased Fv/Fm and lower catalase activity. Seawater fog can not only be used to delay/reduce bleaching while thermal stress is high but can also enhance recovery and post-stress repair processes of corals. In order to advance seawater fogging as a practical reef intervention tool, engineering advances should be accompanied by in-situ trials that capture complex coral-environment interactions and assess ecosystem-wide responses.

摘要：准确的三维温度和盐度初始场对于区域短期海洋预报至关重要，但由于现场剖面稀疏且卫星观测主要描述海面，西印度洋的地下约束仍然有限。本研究评估了一种通过使用三维变分数据同化方案 (FVCOM-3DVAR) 将预训练语言模型 (PLM) 重建的温盐场同化到有限体积社区海洋模型中来改进短期预报的方法。该方法适用于西印度洋，覆盖15°S–10°N，33°E–60°E。通过非同化控制实验（Control_run）、模块化海洋资料同化系统同化（MODAS_ass）和PLM重建场同化（PLM_ass）来评估5天滚动预报的预报性能。 世界海洋数据库 (WOD) 剖面用于基于剖面的验证，哥白尼海洋环境监测服务 (CMEMS) 网格场用于 2021 年 2 月、5 月、8 月和 11 月的空间连续参考评估。结果表明，在大多数深度和交付周期，PLM_ass 产生的温度和盐度均方根误差 (RMSE) 低于 Control_run 和 MODAS_ass。相对于 Control_run，PLM_ass 在 100-200 m 处将平均温度 RMSE 降低了 28. 0%，在 0-100 m 处将平均盐度 RMSE 降低了 23. 5%；与 MODAS_ass 相比，分别减少了约 16. 6% 和 14. 2%。空间诊断显示了可变、深度和区域相关的影响，其中温跃层温度预测的改善最为强劲。 这项研究为在稀疏观测条件下将人工智能重建的地下信息纳入区域海洋预报系统提供了可行的途径。
Abstract: Accurate three-dimensional temperature and salinity initial fields are essential for regional short-term ocean forecasting, but subsurface constraints remain limited in the Western Indian Ocean because in situ profiles are sparse and satellite observations mainly describe the sea surface. This study evaluated a method to improve short-term forecasts by assimilating pretrained language model (PLM)-reconstructed thermohaline fields into the Finite Volume Community Ocean Model with a three-dimensional variational data assimilation scheme (FVCOM–3DVAR). The method was applied to the Western Indian Ocean, covering 15° S–10° N, 33° E–60° E. A non-assimilation control experiment (Control_run), Modular Ocean Data Assimilation System assimilation (MODAS_ass), and PLM reconstructed-field assimilation (PLM_ass) were conducted to evaluate the forecast performance with 5-day rolling forecasts. World Ocean Database (WOD) profiles were used for profile-based validation, and Copernicus Marine Environment Monitoring Service (CMEMS) gridded fields were used for spatially continuous reference evaluation in February, May, August, and November 2021. The results demonstrated that PLM_ass produced lower temperature and salinity root-mean-square errors (RMSEs) than Control_run and MODAS_ass at most depths and lead times. Relative to Control_run, PLM_ass reduced mean temperature RMSE by 28.0% at 100–200 m and mean salinity RMSE by 23.5% at 0–100 m; compared with MODAS_ass, the reductions were approximately 16.6% and 14.2%, respectively. Spatial diagnostics showed variable-, depth-, and region-dependent impacts with the most robust improvement in thermocline temperature forecasts. This study provides a feasible pathway for incorporating AI-reconstructed subsurface information into regional ocean forecasting systems under sparse observation conditions.

摘要：全世界的热带珊瑚礁生态系统正受到气候变化和人类活动的双重压力的影响，人类活动将大量营养物质和沉积物引入沿海地区。在这种情况下，浮游植物代表了溶解的无机营养物和珊瑚礁食物网之间的关键联系，但它们在这些生态系统中的作用仍未得到充分研究。我们于 2022 年 9 月和 2023 年在自然光和温度条件下利用野外微观实验研究了白保礁（日本冲绳岛石垣岛）夏季浮游植物群落对营养物富集的生态反应。处理方法包括单独和组合添加氮、磷和硅。 在复合营养条件下，叶绿素 a (Chl a) 浓度在三天后增加，而单一营养添加产生的反应有限，表明珊瑚礁中氮和磷的强烈共同限制。对大小分级叶绿素 a 的分析揭示了从通常主导热带寡营养生态系统的超微型浮游植物向由增强的养分可用性支持的更大群体的转变。我们的结果显示了营养物富集事件对珊瑚礁浮游植物大小结构和生物地球化学循环的短期影响，并强调了营养物富集下中上层过程在珊瑚礁碳动态中的重要性。
Abstract: Tropical coral reef ecosystems worldwide are being impacted by combined pressures of climate change and human activities that introduce large quantities of nutrients and sediments into coastal areas. In this context, phytoplankton represent a critical link between dissolved inorganic nutrients and coral reef food webs, yet their role in these ecosystems remains understudied. We investigated ecological responses of the summer phytoplankton community of Shiraho Reef (Ishigaki Island, Okinawa, Japan) to nutrient enrichment using field-based microcosm experiments under natural light and temperature conditions in September 2022 and 2023. Treatments included single and combined additions of nitrogen, phosphorus, and silicon. Chlorophyll a (Chl a ) concentrations increased after three days under combined nutrient conditions, whereas single-nutrient additions produced limited responses, indicating a strong co-limitation by nitrogen and phosphorus in the reef. Analysis of size-fractionated Chl a revealed shifts from picophytoplankton that typically dominate tropical oligotrophic ecosystems toward larger groups supported by enhanced nutrient availability. Our results show short-term impacts of nutrient enrichment events on phytoplankton size structure and biogeochemical cycling in coral reefs, and highlight the importance of pelagic processes in coral reef carbon dynamics under nutrient-enrichment.

摘要：海洋热浪（MHW）被定义为长时间的异常高温海洋。这些事件可能对海洋生态系统产生严重影响，如果发生在海面，可能会反馈到大气中，改变内陆气温和降水。我们使用一套全面的模型、再分析和观测数据集来调查北海 MHW 的近期变化。所有数据集都显示出显着的变暖趋势，同时伴随着 MHW 频率的显着增加。相比之下，包括德国湾在内的北海许多地区的重灾区最大强度有所下降。如果消除温度的线性趋势，则 2019 年之后仅检测到少数 MHW，这表明自然变化削弱了长期变暖的影响。 虽然不同的天气模式与重灾区的出现有关，但仅它们的发生并不足以触发它们。由于热含量是一个综合量，除了季节期间的主要天气模式外，季节开始时的海洋温度（海洋预处理）也是一个关键因素。因此，只有在冬季，我们才发现 MHW 对既定气候指数有显着依赖性。在我们的研究区域，MHW 是由短期天气相关变化和长期季节性到十年变化共同作用的结果。此外，我们发现德国湾表面温度的演变很大程度上取决于当地的大气条件，而不是大西洋的远程变化。 尽管温水通过英吉利海峡的流入很重要，但控制其体积运输和温度的是大气。大气条件本身是否与大西洋的远程变化有关仍有待研究。
Abstract: Marine heatwaves (MHWs) are defined as prolonged periods of anomalously high ocean temperatures. These events can have severe impacts on marine ecosystems and, if they occur at the surface, can feed back on the atmosphere, changing inland air temperatures and precipitation. We use a comprehensive set of model, reanalysis, and observational datasets to investigate recent changes in North Sea MHWs. All datasets show a significant warming trend, accompanied by a marked increase in the frequency of MHWs. In contrast, the maximum intensity of MHWs has decreased in many regions of the North Sea, including the German Bight. If the linear trend in temperature is removed, only a few MHWs have been detected after 2019, suggesting natural variability has damped the effect of the long-term warming. While distinct weather patterns are associated with the onset of MHWs, their occurrence alone is not sufficient to trigger them. As the heat content is an integrated quantity, the ocean temperature at the beginning of the season (ocean preconditioning) is a key factor, in addition to prevailing weather patterns during the season. As a consequence, only in winter we find a significant dependency of MHWs on established climate indices. In our study region, MHWs result from a combination of short-term weather-related variability and longer-term seasonal to decadal variability. Furthermore, we find that the evolution of the surface temperature in the German Bight is largely determined by local atmospheric conditions rather than remote variability in the Atlantic. Although the inflow of warm water through the English Channel is important, it is the atmosphere that controls its volume transport and temperature. Whether the atmospheric conditions themselves are linked to remote variability in the Atlantic Ocean remains to be studied.

Abstract: In this study, the mechanisms of formation and distribution characteristics of exodynamic processes developing in the Nakhchivanchay basin over the territory were systematically investigated based on modern scientific methods. During the study, the geological structure, lithological composition, tectonic features, and geomorphological conditions of the territory were taken as the main objects of analysis. The intensity and spatial differentiation of the processes formed as a result of the interaction of these factors were widely evaluated. Within the framework of the study, the morphometric indicators of the territory were determined by applying digital relief models, satellite data and geographic information systems technologies. In particular, the degree of inclination of the slopes, exposure characteristics and the level of fragmentation of the relief were analyzed in detail. In addition, the distribution of structural linearities and tectonic faults was assessed using cartographic methods and sensitive areas in terms of risk were identified. The conducted analyses showed that erosion, landslides, denudation, and floods are observed more intensively mainly on steep slopes, in areas where weakly resistant rocks are distributed and in tectonically active zones. At the same time, climatic and hydrological factors, especially the amount of precipitation and the formation of surface runoff, play an important role in strengthening these processes. In addition, it was determined that anthropogenic impacts are also significant. Agricultural activity, improper land use and construction work lead to disruption of the natural balance in some areas and acceleration of processes. In particular, the weakening of vegetation cover further increases the risk of erosion.
