Ocean circulation in the Yellow and East China Seas is very rich in mesoscale phenomena, such as eddies, fronts, upwellings, river plumes, etc. Among others, having drawn tremendous attention from oceanographic community in the past for nearly 50 years are mainly the Yellow Sea Cold Water Mass (YSCWM) and its related circulation, the Yellow Sea Warm Current (YSWC), the East China Sea  相似文献

STUDY ON DEVELOPMENT STRATEGY OF SHIPPING CENTERS AND TRANSPORTATION NETWORKS IN THE YELLOW SEA RIM IN THE YELLOW SEA RIM     

JINFeng-jun 《中国地理科学(英文版)》2003,13(2):97-103

It is very important to establish cooperative mechanism to guarantee all members to develop their e-conomies in the Yellow Sea Rim. In this paper, the development strategies ofshipplng centers and transportation networkare discussed based on economic giobalization tendency. The results argue that a united transportation network should bebuilt in order to promote the economic competition of Northeast Asia in the world. As a key component of the economiccooperation, a hierarchical shipping centers network should be established with Hong Kong, Shanghai, Pusan, Koho,and Tokyo as cores. The authorities of China, Japan, R. O. Korea and D. P. B. Korea should make more efforts tobuild a set of cooperation institutions based on raising the transportation efficiency.  相似文献

Tidal effects on temperature front in the Yellow Sea   总被引：5，自引：0，他引：5

Temperature front (TF) is one of the important features in the Yellow Sea, which forms in spring, thrives in summer, and fades in autumn as thermocline declines. TF intensity ⋎S _T ⋎ is defined to describe the distribution of TF. Based on the MASNUM wave-tide-circulation coupled model, temperature distribution in the Yellow Sea was simulated with and without tidal effects. Along 36°N, distribution of TF from the simulated results are compared with the observations, and a quantitative analysis is introduced to evaluate the tidal effects on the forming and maintaining processes of the TF. Tidal mixing and the circulation structure adapting to it are the main causes of the TF.

MONITORING THE DIFFUSION OF SUSPENDED SEDIMENTS AND STABILITY OF TIDAL RADIAL SAND RIDGES AREA USING MULTI-SATELLITE REMOTE SENSING DATA     

黄海军  何宜军 《中国海洋湖沼学报》2001,19(4):361-367

Nine Landsat TM tapes and images and MSS images, 10 NOAA tapes and images and 1 SAR image from 1973 to 1997 were used to analyse the diffusion of suspended sediments and the change of tidal radial sand ridges in the northern part of the Changjiang River delta, the South Yellow Sea. The results showed that the diffusion of suspended sediments was controlled by the tide, net current, and submarine topography in this area. The distribution of suspended sediments had close relationship with thesubmarine topography. The old Huanghe River delta and the Changjiang River comprise the main sediment supply for the formation of radial sand ridges, whose evolution can be divided into three stages since the Huangbe River changed its course and flowed northward into the Bohai Sea.  相似文献

笔者通过对南黄海的地震活动特征分析研究,认为该区的地震活动水平远高于扬州-铜陵地震带,应作为一独立的地震区(带)存在,以利于对该海域的地震研究和监测;并对其地震活动有关的若干问题提出讨论  相似文献   

北黄海盆地北缘断裂带及其特征     

田振兴  张训华  肖国林  孟祥君 《海洋地质与第四纪地质》2007,27(2):59-63

根据最新调查获得的北黄海盆地海洋重力、海洋与航空磁力和多道地震资料,结合以往周边地区的资料,编制了北黄海空间重力异常图、布格重力异常图、磁力异常图。在重磁基础图件的基础上,通过解析延拓、任意方向导数计算、离散小波变换等处理,结合地震和地质资料,对北黄海北缘断裂带进行了综合分析。确定了北黄海北缘断裂带的存在,并对该断裂带的延伸长度、切割深度和性质进行了分析,指出北黄海北缘断裂带是辽东隆起与北黄海盆地的界线,断裂带两侧具有明显不同的地球物理场特征;而且断裂带具有多期活动的特点,对北黄海盆地的形成演化具有重要的控制作用。  相似文献   

采用碳氮稳定同位素技术对黄海中南部鳗鱼食性的研究          下载免费PDF全文

郭旭鹏李忠义  金显仕戴芳群 《海洋学报》2007,29(2):98-104

根据2005年4～5月在黄海和长江口海域进行的春季底拖网调查，应用稳定同位素方法研究了黄海中南部鯷鱼（Engraulis　japonicus）及其可能摄食饵料的碳氮稳定同位素比值，结果表明：（1）黄海中南部鯷鱼的食物组成为不同粒径的浮游动物、太平洋磷虾（Euphausia pacifuca）和仔稚鱼，其中以粒径为500-900μm的浮游动物为主，贡献比例占61％～84％；仔稚鱼贡献比例占16％～21％，较传统胃含物方法分析的结果小；（2）黄海中部海域鯷鱼的碳氮稳定同位素比值平均值较南部海域高，原因可能与各海域的能量来源不同或存在微食物环有关，也可能与不同海域鯷鱼的能量转换途径不一样，即与食物链长短不一有关．  相似文献
