申锦瑜教授(达尔豪斯大学):灾害性天气下浪流相互作用的机理性研究

主要内容:海浪和海流是海洋里最为重要的动力学现象。为了简化研究,长期以来,此两大类海洋动力学现象是单独研究的。本讲座介绍海流-海浪相关作用的基本原理,并利用本团队开发的海流-海浪耦合模型的实例,介绍灾害性天气条件下波流相互作用的机理性研究。

邢久星研究员(清华大学):南海北部的一些关键物理海洋过程

主要内容:近海物理海洋的两个关键方面是陆-海相互作用和大陆架-深海相互作用(land-sea interaction and shelf-deep ocean interaction. 通过这个报告,我希望同大家交流讨论一些有关的重要物理海洋过程,特别是南海北部大陆架边缘的内潮、近惯性运动及相互作用,中尺度涡旋,冲淡水与潮流相互作用等。

张艳伟副教授(同济大学):南海东北部深海沉积动力过程的观测研究

主要内容:南海受控于黑潮、太平洋深层水及季风、台风多种影响机制,具有强边界流/等深流、中尺度涡、内潮等多尺度运动,每年接受周边河流输入的巨量陆源沉积物,因此南海深海沉积物搬运过程既复杂又极具代表性。自2011年起,通过在南海北部布放综合锚系观测系统,用于监测和理解南海东北部陆源沉积物从源到汇的搬运过程。通过高分辨率、长期多参数观测结果,我们发现台风触发台湾高屏海底峡谷浊流频繁,是台湾陆源沉积物从岸向深海搬运的主要动力机制,中尺度涡引起的深海强动力可以远距离搬运沉积物,而具有较强季节性变化的等深流是跨海盆搬运深海沉积物的主要过程。

  

1100-1120

连尔刚博士(同济大学):南海暖流与台湾暖流起源:海水氢氧同位素示踪

主要内容:南海暖流与台湾暖流因其冬季逆风流的特性而备受关注,对其下游海域的温、盐、碳、热量及营养盐收支平衡具有重要影响。近几十年来,逆风流的起源与动力成因机制一直是国内外诸多学者的关注热点,且至今尚存争议。本次报告将介绍利用氢氧同位素示踪剂,开展东海台湾暖流与台湾海峡西南部南海暖流溯源工作取得的一些进展。

潘顺琪教授(卡迪夫大学):Assessing Extreme Waves and Surge in the Northwest Pacific Ocean Region

Abstract: This talk will present the results on the long-term modelling of wave climate in the northwest Pacific Ocean region using coupled FVCOM-SWAVE and FVCOM modelling system with the implementation of a parameter typhoon model. The model was driven by the ECMWF reanalysis wind and sea surface pressure data over a 35-year period from 1979 to 2013, which was modified and refined by the measured typhoon parameters. The model results were used to assess the impact of typhoons on the wave climate, as well as the extreme conditions of the wave and surge and directional and seasonal variation over the coastal waters along the China coasts.


1440-1510

Dr. Taavi Liblik(同济大学,Tallinn University of Technology):Variability in stratification and its consequences in the areas of freshwater influence.

Abstract: Thermal and haline buoyancy are both important sources of creating stratification in the regions of freshwater influence. Observational results from the area off the Changjiang Estuary and from the Baltic Sea will be presented. Both marine areas are under strong influence of freshwater and anthropogenic impact from land. Variability in transport and mixing of the fresher water have considerable implications to these marine systems. Forcing in the air-sea interface affects whole water column in both marine areas. Examples of the role of wind-driven processes on the water column structure and oxygen distributions will be presented.


1510-1530

涂俊彪博士(同济大学):高浊度强潮型河口小尺度物理过程

主要内容:小尺度物理过程(如湍流混合等)控制着河口海岸坏境中能量和物质的交换和输运,是物理海洋学和沉积动力学研究关注的重点。中国海岸分布众多高浊度、强潮型河口,目前对于此类河口小尺度物理过程的研究仍较为缺乏。本次报告将介绍本团队近年来基于现场观测研究取得的一些进展,主要包括:(1)强涌潮作用下的湍流动力;(2)悬浮沉积物层结对湍流混合的影响;(3)泥跃层中的内波与剪切不稳定。

  

1530-1550

吴伊婧博士(同济大学):Extending Kuroshio subsurface water to the north of Changjiang Estuary: evidence from radiocarbon content in dissolved inorganic carbon

主要内容:Intrusion of the Kuroshio subsurface water(KSSW) to the Changjiang Estuary is crucial for the development of hypoxia. Radiocarbon contents(Δ14C) can be used to trace the movement and interaction of water masses. However, a knowledge gap exists targeting DI14C in the Changjiang Estuary, and no data are available for the inner and middle shelf of the East China Sea. This talk will present our recent work in using DI14C to trace the intrusion of KSSW, and offers a glimpse into the organic matter decomposition process along the path of KSSW intrusion.

  

1550-1610

范代读教授(同济大学):东海海底科学观测网进展介绍

主要内容:海底观测网小衢山试验站建设运行情况;小衢站记录的长江径流枯洪转变过程中对河口冲淡水过程的影响分析;在建东海海底观测网基本情况。
