The basic structure and intraseasonal evolution of currents in the southeastern Andaman Sea was analyzed based on data collected in 2017 from two subsurface moorings(C1 and C5).Periodic variation in the upper ocean currents of the Andaman Sea was investigated by combining observational and satellite *** observations show that rapid changes of current speed and direction occurred in May and June,with a significant increase in current velocity at the C1 *** the second half of the year,southward flow dominated at the C1 mooring,and alternating northward and southward flows were evident at the C5 mooring during the same period but the northward flow prevailed in boreal *** addition,analysis of the power spectra of the upper currents revealed that the tidal period at both moorings is primarily semidiurnal with weaker energy than that of the low-frequency *** upper ocean currents at the C1 and C5 moorings exhibited intraseasonal variation of 30-60 d and 120 d,while the zonal current at the C1 mooring exhibited a notable period of approximately 180 *** analysis indicated that the variability of currents in the Andaman Sea is influenced primarily by equatorial Kelvin waves and Rossby wave ***,our results suggest that equatorial Kelvin waves from the eastern Indian Ocean entered the Andaman Sea in the form of Wyrtki Jets and propagated primarily along two distinct pathways during the observation *** addition to coastal boundary Kelvin waves,it was found that a branch of the Wyrtki Jet that directly enters the Andaman Sea and flows northward along the slope of the continental shelf,and reflected Rossby wave packets by topography.

微塑料是一类土壤中广泛存在的新兴污染物,其对土壤磷吸附的影响尚不明确。文中分析了0.1%~10%含量微塑料对土壤磷吸附特性的影响及机制。结果表明,微塑料会使得吸附第一阶段液膜扩散阶段速率显著提升(p<0.05)。与纯土壤(qe=6.456 mg/g)相比,含量1%以下的微塑料显著降低了土壤磷吸附容量(p<0.05),但5%以上的微塑料显著提升了土壤磷吸附容量(p<0.05)。同等含量下,微塑料粒径越小,微塑料-土壤体系的磷吸附量越大。微塑料可与磷竞争吸附位点,降低了微塑料-土壤体系对磷的吸附,但微塑料也可直接吸附磷,故当微塑料为5%及以上时,微塑料-土壤体系对磷的吸附量升高。因此,土壤微塑料污染可显著改变土壤对磷的吸附特性,且与微塑料的含量和粒径等因素密切相关。

由于近几十年来日益增强的人类活动影响,近海海洋环境较过去发生了巨大变化;科学认知近海海洋环境特征、变化和控制因素对于应对全球变化具有重要意义,是当前海洋学关注的重要议题。东海作为中国重要的海洋区域之一,存在独特的环流系统,孕育了大河口、上升流和黑潮三个代表性的生态系统,其海洋科学研究对于我国的海洋资源开发、环境保护和国家安全具有重要意义。本文通过对东海区域海洋学研究的现状进行综述,围绕海洋生物地球化学这一主线,重点总结了物理海洋学、海洋化学、海洋地质学和生物海洋学的相关研究进展,分析了目前存在的问题,并展望了未来的发展方向。研究表明,东海区域海洋环境受到人类活动和气候变化的深刻影响,呈现新的变化格局;长江径流输入、黑潮北上及其入侵陆架是东海三大生态系统格局形成的主要驱动力。除主要的环流结构外,穿刺锋面和跨陆架海流是连接东海内陆架和外陆架水体的主要动力过程,并促进了碳等重要生源物质的跨陆架输送。相关研究在海洋生态环境、应对气候变化、海洋灾害等方面取得了一定的成果,但仍面临着数据不足、研究领域不够广泛等挑战。东海海洋环境在时间和空间上变化均较大,且存在近岸富营养化、大河口低氧现象等主要环境问题,因此有必要加强东海区域海洋学的研究。未来,应鼓励自由探索研究,加强国内、国际合作,提高数据共享和技术创新能力,推动东海海洋研究迈向更高水平。

Seasonal characteristics and forcing mechanisms of the surface Kuroshio branch intrusion into the South China Sea

引用

Acta Oceanologica Sinica 2019年第1期38卷 13-21页

作者： jingsong guo Zhixin Zhang Changshui Xia Binghuo guo Key Laboratory of Marine Science and Numerical Modeling First Institute of Oceanography Ministry of Natural Resources Laboratory for Regional Oceanography and Numerical Modeling Pilot National Laboratory of Marine Science and Technology (Qingdao)

Using observational data of Argos satellite-tracked drifters from 1988 to 2012, we analyzed seasonal characteristics of the surface Kuroshio branch(KB) intrusion into the South China Sea(SCS). The analysis results are as *** surface KB originates from the southern Balintang Channel(BLTC) and Babuyan Channel(BBYC). It begins in late September, reaches peak strength in November–December, and declines at the end of March. The mean speed of drifters along the KB path during their traverse of the Luzon Strait(LS) was 43% faster than during the two days before entering the LS for the flow originating from the southern BLTC, but there was a 24% increase in speed for the flow from the BBYC. The observations show that in winter, monthly-mean sea-level anomalies(SLAs) were positive southwest of Taiwan Island and extended to the northern LS. The SLAs were negative northwest of Luzon Island and extended to the southern LS, which acted like a pump, forcing a part of Kuroshio water westward into the SCS. The condition under which the KB forms was solved by a set of simplified motion equations. The results indicate that whether the KB can form depends upon the sea-level gradient at the central LS and region to the west, as well as the location, speed and direction of Kuroshio surface water when it enters the LS.

The summertime circulation of the Bohai Sea simulated from a high-resolution wave-tide-circulation coupled model

Acta Oceanologica Sinica 2019年第1期38卷 32-37页

The Bohai Sea is a shallow semi-enclosed inner sea with an average depth of 18 m and is located at the west of the northern Yellow Sea. The climatological circulation pattern in summer of the Bohai Sea is studied by using a wave-tide-circulation coupled model. The simulated temperature and the circulation agree with the observation well. The result shows that the circulation pattern of the Bohai Sea is jointly influenced by the tidal residual current, wind and baroclinic current. There exists an obvious density current along the temperature front from the west part of the Liaodong Bay to the offshore area of the Huanghe Estuary. In the Liaodong Bay there exists a clockwise gyre in the area north to the 40°N. While in the area south to the 40°N the circulation shows a two-gyre structure, the flow from the offshore area of the Huanghe Estuary to the Liaodong Bay splits into two branches in the area between 39°N and 40°N. The west branch turns into north-west and forms an anti-clockwise gyre with the south-westward density current off the west of the Liaodong Bay. The east branch turns to the east and forms a clockwise gyre with the flow along the east coast of the Liaodong Bay. The forming mechanism of the circulation is also discussed in this paper.

Meso-scale eddies are important features in the South China Sea（SCS）. The eddies with diameters of 50–200 km can greatly impact the transport of heat, momentum, and tracers. A high-resolution wave-tide-circulation coupled model was developed to simulate the meso-scale eddy in the SCS in this study. The aim of this study is to examine the model ability to simulate the meso-scale eddy in the SCS without data assimilations The simulated Sea Surface Height（SSH） anomalies agree with the observed the AVISO SSH anomalies well. The simulated subsurface temperature profiles agree with the CTD observation data from the ROSE（Responses of Marine Hazards to climate change in the Western Pacific） project. The simulated upper-ocean currents also agree with the main circulation based on observations. A warm eddy is identified in winter in the northern SCS. The position and domain of the simulated eddy are confirmed by the observed sea surface height data from the AVISO. The result shows that the model has the ability to simulate the meso-scale eddy in the SCS without data *** three-dimensional structure of the meso-scale eddy in the SCS is analyzed using the model result. It is found that the eddy center is tilted vertically, which agrees with the observation. It is also found that the velocity center of the eddy does not coincide with the temperature center of the eddy. The result shows that the model has the ability to simulate the meso-scale eddy in the SCS without data assimilations. Further study on the forming mechanism and the three-dimensional structure of the meso-scale eddies will be carried out using the model result and cruise observation data in the near future.

The observed tidal and residual currents in the Andaman Sea during the second half of 2016

Acta Oceanologica Sinica 2018年第9期37卷 13-21页

The characteristics of currents and tidal currents in the Andaman Sea（AS） are studied during the second half of2016 using observed data from a moored acoustic Doppler current profiler（ADCP） deployed at 8.6°N, 95.6°*** the observation period, the mean flow is 5–10 cm/s and largely southward. The root mean square and kinetic energies of the low and high frequency flows, which are divided by a cutoff period of 5 d, are at the same level, indicating their identical importance to the total current. A power spectrum analysis shows that intraseasonal oscillations, a tidal-related semilunar month signal, a semidiurnal tidal signal and periods of 3–4 d are prominent. The barocliny of an eddy kinetic energy is stronger than the mean kinetic energy, both of which are the strongest on the bottom and the weakest at 70 m depth. Residual currents are largely southward（northward） during the summer（winter） monsoon season. Two striking peaks of the southward flow cause the 80 d period of meridional currents. The first peak is part of a large-scale circulation, which enters the AS through the northern channel and exits through the southern channel, and the second peak is part of a local vortex. The 40 d oscillation of the zonal current is forced by geostrophic variations attributed to local and equatorial remote forcing. The tidal current is dominated by semidiurnal constituents, and among these, M2 and N2 are the top two largest major axes. Moreover, astronomical tidal constituents MM and MSF are also significant. Diurnal constituents are weak and shallow water tides are ignorable. The aims are to introduce the new current data observed in the AS and to provide initial insights for the tidal and residual currents in the Andaman Sea.

我们在冬季季风期间学习了自台湾东面的菲律宾海流向日本的暖流侵入的驱动力进华南海(SCS ) ，用进入通过来自菲律宾的海的 Balintany 和 Babuyan 隧道的吕宋岛海峡(LS ) 的追踪卫星的流浪者。没有一个重要变化，在冬季通过 Babuyan 隧道的大多数流浪者在速度进入了内部 SCS。然而，通过 Balintany 隧道的流浪者的一半在 30 cm/s 进入了 SCS，它比他们什么时候进入 LS 快。另外的一半继续移动进自台湾东面的菲律宾海流向日本的暖流向西北、对北方太平洋回来。量的分析，使用的表面 climatological 风和海出现高度异例(SSHa ) 数据通过 Balintany 隧道在在二条隧道和他们的加速之间的流浪者的速度向两个解释了差别。结果建议海的积极南方的坡度出现在吕宋岛海峡的高度，由东北季风，以及 Ekman 流动驾驶的海水的连环相撞引起了，通过 Babuyan 和 Balintany 隧道贡献自台湾东面的菲律宾海流向日本的暖流侵入进 SCS。前者可以是主要驱动力。
