趋势总结Trend Summary
本期重点关注 BGC-Argo、海色遥感/海洋光学、海洋热浪、浮游植物垂向结构和碳泵过程。筛选逻辑不再只限于重点期刊；当高影响力期刊当天新增较少时，会额外检索重点关注团队作者的新论文，并用海洋、海色/光学和碳循环关键词过滤，再从其他相关期刊补充候选论文。
This issue focuses on BGC-Argo, ocean-colour remote sensing, ocean optics, marine heatwaves, vertical phytoplankton structure and carbon-pump processes. The selection is no longer limited to priority journals; when few high-impact papers are newly available, the workflow also checks focused-team authors and filters those papers with ocean, ocean-colour/optics, and carbon-cycle keywords before adding other relevant journals as supplements.

摘要：西北太平洋（NWP）的海洋热浪变得越来越频繁和持续，但其多季节持续的机制仍然知之甚少。通过观测分析和气候模型实验，我们证明数值天气预报海洋热浪主要是由准静止波数5环全球波（CGW）模式驱动的，该模式独立于厄尔尼诺-南方涛动运行。 CGW 在夏季调节地表热通量，触发一个自我强化的反馈循环，其中 NWP 变暖加剧了 CGW 模式，在整个温暖季节放大和延长热浪。此外，北大西洋北部由 CGW 驱动的夏季变暖通过海洋热惯性持续到冬季，激发了传播回 NWP 的大圆波模式，在寒冷季节维持热浪。 大气波和跨盆地相互作用之间的相互作用使得多年海洋热浪事件成为可能。对观测数据和气候模型模拟的分析表明，近几十年来，CGW 的影响不断增强，表明在持续的全球变暖下，NWP 海洋热浪更加频繁和持续。
Abstract: Marine heatwaves in the Northwestern Pacific (NWP) have become increasingly frequent and persistent, yet the mechanisms enabling their multiseasonal duration remain poorly understood. Through observational analyses and climate model experiments, we demonstrate that NWP marine heatwaves are primarily driven by a quasistationary wavenumber 5 circumglobal wave (CGW) pattern that operates independently of El Niño–Southern Oscillation. The CGW modulates surface heat fluxes during summer, triggering a self-reinforcing feedback loop where NWP warming intensifies the CGW pattern, amplifying and prolonging heatwaves across extended warm seasons. Additionally, CGW-driven summer warming in the northern North Atlantic persists into winter through oceanic thermal inertia, exciting a great-circle wave pattern that propagates back to the NWP, sustaining heatwaves through cold seasons. This interplay between atmospheric waves and trans-basin interactions enables multiyear marine heatwave events. Analysis of observational data and climate model simulations reveals a strengthening CGW influence in recent decades, indicating more frequent and prolonged NWP marine heatwaves under ongoing global warming.

摘要：泥炭地是全球主要的碳库，在气候调节和生态系统功能中发挥着至关重要的作用。然而，由于进入这些地点的困难以及大规模实地调查的成本高昂，人们对热带地区，特别是中部非洲的空间分布仍然知之甚少。基于结合多个来源的数据可以提供泥炭存在迹象以优化下奥戈韦三角洲盆地研究的假设，本研究提出了一个空间建模框架，旨在利用集成光学、雷达、地形和结构信息的多源遥感数据来估计加蓬下奥戈韦三角洲泥炭地出现的概率。 具体来说，它的目的是产生可能控制下奥古埃泥炭存在的解释变量，以及其出现的概率图。来自 Landsat 8 的光谱指数（NDVI 和 NDWI）、不同季节 ALOSPALSAR 的雷达参数（HH 后向散射和 RFDI）以及来自数字高程模型 (DEM) 的地形变量，例如地形湿度指数 (TWI)、海拔和坡度，以及土壤和年代地层数据，被用作基于解析的多标准分析的代理。层次分析法（AHP）。生成的概率图突出显示了 470,834 个大片区域。 1公顷的低洼地势，永久涝渍，极有可能出现泥炭地。 这种可重复和可转让的方法构成了热带泥炭地测绘以及有关生物多样性保护和减缓气候变化决策的相关工具和里程碑。
Abstract: Peatlands are major global carbon reservoirs and play a vital role in climate regulation and ecosystem functioning. However, their spatial distribution remains poorly understood in tropical regions, particularly in Central Africa, given the difficulties in accessing these sites and the high costs of large-scale field surveys. Based on the hypothesis that combining data from multiple sources can provide indications of peat presence to optimise research in the Lower Ogooué Delta basin, this study proposes a spatial modelling framework aimed at estimating the probability of peatland occurrence in the Lower Ogooué Delta in Gabon, using multi-source remote sensing data that integrates optical, radar, topographic, and structural information. Specifically, it aims to produce the explanatory variables likely to govern the presence of peat in the Lower Ogooué, as well as a probability map of its occurrence. Spectral indices derived from Landsat 8 (NDVI and NDWI), radar parameters from ALOSPALSAR (HH backscatter and RFDI) across different seasons, as well as topographic variables from the Digital Elevation Model (DEM), such as the Topographic Wetness Index (TWI), altitudes and slopes, as well as soil and chronostratigraphic data, were used as proxies in a multi-criteria analysis based on an Analytic Hierarchy Process (AHP). The resulting probability map highlights vast areas of 470,834.1 hectares of low-lying terrain, permanently waterlogged, with a high probability of peatland occurrence. This reproducible and transferable methodology constitutes a relevant tool and a milestone for the mapping of tropical peatlands and for decision-making regarding biodiversity conservation and climate change mitigation.
