| 1. | Holocene tephra deposits in the northern okinawa trough 冲绳海槽北部的全新世火山碎屑沉积 |
| 2. | Grain - size variations of terrigenous sediment sequences in the south okinawa trough 冲绳海槽南部沉积层序的粒度特征 |
| 3. | Elemental geochemical records of modern seafloor hydrothermal activities in sediments from the central okinawa trough 冲绳海槽中部现代海底热液活动在沉积物中的元素地球化学记录 |
| 4. | The characteristics of the sediment from the okinawa trough are controlled by provenance . some major and trace elements vs . al scatter plots show clearly the evolution stage of the sedimentary supply to okinawa trough 冲绳海槽沉积物的化学特征受控于物质来源,用元素对al的散点图可以明显显示冲绳海槽物源供应具有阶段性变化的特点。 |
| 5. | The provenance of the sediment in middle okinawa trough during the last glacial maximum is the shelf of the east china sea . the characteristics of elemental geochemistry ascertain that the sediment was derived from the paleo - changjiang river 末次盛冰期冲绳海槽中部陆源物质来源于东海陆架,元素地球化学特征显示这些沉积物主要来源于古长江的入海物质。 |
| 6. | According to these anomalous implications , some possible areas for gas hydrates are pointed out , such as the xisha trough , the dongsha island slope , the marginal bijianan basin , the north luzon trench , the nansha troug , the middle - south to southwest okinawa trough etc 中国近海海域的西沙海槽、东沙群岛岛坡、笔架南盆地、北吕宋海槽、南沙海槽、冲绳海槽中南部至西南部等是天然气水合物的可能赋存区。 |
| 7. | The three - dimensional topography figures of major typical hydrothermal regions are drawn on the basis of field - measured bathymetric data of the okinawa trough and collecting a large number of data on bathymetry , multibeam and seismic profiles of other major typical hydrothermal regions 在冲绳海槽热液活动区实测水深资料的基础上,广泛收集了其他典型热液活动区的水深、多波束、地震剖面等资料,据此绘制出主要典型热液活动区的三维地形图。 |
| 8. | Study method of sediment color reflectance in shelf has been established based on lots of investigative studies , obtained more than 7000 units of data of color reflectance using minolta cm - 2002 spectrophotometer from 165 cores in the yellow sea and the east china sea , illustrated the distributional rules of color reflectance in sediment of the shelf of south yellow sea , the shelf of north east china sea shelf and okinawa trough for the first time 本论文基于大量的实验研究,建立了陆架沉积物颜色反射率的研究方法。利用minoltacm - 2002光谱光度计测量了黄海、东海海区的165个岩心样品,获得了7000多个有效的颜色反射率数据,首次给出南黄海陆架、东海陆架北部、冲绳海槽等海区沉积物的颜色反射率分布规律。 |
| 9. | Concentrations of total suspended matter ( ctsm ) is unanimous with observational data and other scholars " researching results . the distribution of ctsm is higher along coast than other areas there is a tongue - like zone with high ctsm from north to southeast . the transport simulation result reveals that sm can spread to the okinawa trough for enough sea water mixing in winter . but in summer . sm can not traverse the big water barrier of kushino for different circulation character . this difference is probably related to the shifting n - s monsoon 悬浮体输送表明,在冬季,悬浮体除了在陆架上发生扩散外,由于海水的强烈混合作用和环流的季节性变化,部分中、底层悬浮体可扩散至冲绳海槽甚至西太平洋;在夏季,由于海水层化及夏季环流特征,悬浮体基本不能穿越黑潮这一水障,这一差异可能是由于季风和不同环流特征所引起的。 |
