The IOD signal in the upper-ocean Indonesian Throughflow since the mid-1970s
LAN Jian, SUN Shuangwen, HONG Jieli
2007, (4): 1-6.
Abstract:
On the basis of simple ocean data assimilation (SODA) reanalysis product, the interannual variability of upper-ocean Indonesian Throughflow (ITF) volume transport since the mid 1970s is examed. The wavelet analysis shows a second prominent interannua...
A survey of baroclinic tides in the Beibu Gulf in the South China Sea
CHEN Ju, WANG Dongxiao, SHI Ping, DU Yan
2007, (4): 7-19.
Abstract:
The principal characteristics of the tides are investigated by a shipborne acoustic Doppler current Profiler at a fixed station located in the Beibu Gulf from 4 to 14 April 2003. Data analysis indicates that the diurnal tidal currents dominate local ...
Seasonal variability of tropical cyclones generated over the South China Sea
WANG Guihua, WANG Hui, QI Yiquan
2007, (4): 20-28.
Abstract:
The seasonal variability of tropical cyclones (CTCs) generated over the South China Sea (SCS) from 1948 to 2003 is analyzed. It peaks in occurrence in August and few generate in late winter (from January to March). The seasonal activity is attributed...
The characteristic differences of tropical cyclones forming over the western North Pacific and the South China Sea
YUAN Jinnan, WANG Dongxiao, LIU Chunxia, HUANG Jian, HUANG Huijun
2007, (4): 29-43.
Abstract:
The best track dataset of tropical cyclones in the western North Pacific (WNP) and the South China Sea (SCS) from 1977 to 2005 during the satellite era, the NCEP/NCAR reanalysis dataset and the extended reconstructed sea surface temperature dataset a...
Spatial information recognizing of ocean eddies based on virtual force field and its application
LI Ce, DU Yunyan, SU Fenzhen, YANG Xiaomei, XU Jun
2007, (4): 44-52.
Abstract:
A new approach to detecting ocean eddies automatically from remote sensing imageries based on the ocean eddy's eigen-pattern in remote sensing imagery and "force field-based shape extracting method" is proposed. First, the analysis on extracting eddi...
Elemental geochemical records of seafloor hydrothermal activities in the sediments from the Okinawa Trough
ZHAI Shikui, YU Zenghui, DU Tongjun
2007, (4): 53-62.
Abstract:
The major and minor element contents in the sediment core H9 from the hydrothermal fields of the Okinawa Trough show a sharp change at the depth of 80 cm. The elements enriched in the upper 80 cm core are those enriched in the hydrothermal deposits a...
Characteristics of platinum-group elements in basalts from spreading axis of Mariana Trough
CAO Zhimin, ZHENG Jianbin, ZHOU Meifu, AN Wei, QI Liang
2007, (4): 63-71.
Abstract:
Total platinum-group elements (PGEs) abundances in basalts from the spreading axis of Mariana Trough ranged from 0.418×10-9 to 1.022×10-9, and primitive mantle-normalized PGE patterns are of positive slope showing the relative enrichment of PPGE (pla...
Reproductive ecology of the mudskipper Boleophthalmus pectinirostris
HONG Wanshu, CHEN Shixi, ZHANG Qiyong, WANG Qiong
2007, (4): 72-81.
Abstract:
The reproductive ecology of the mudskipper Boleophthalmus pectinirostris was investigated during the spawning season in the Funing Bay, Fujian, China. The fish burrows were basically Y-shaped and had two openings onto the mudflats. Part of the inters...
Effect of UV-B radiation on the feeding behavior of the rotifer Brachionus plicatilis
FENG Lei, LI Xin, WANG Jinhe, HAN Honglei, TANG Xuexi, CHEN Xiguang
2007, (4): 82-92.
Abstract:
Effect of UV-B radiation on the feeding behaviour of marine zooplankton is important to assessing the health harm of marine ecosystem due to the gradually enhanced UV-B radiation in air. However, there are a few studies on this topic. The feeding beh...
Phylogenetic diversity and phenotypic characterization of cultivable bacterioplankton isolated from polar oceans
ZENG Yinxin, LI Huirong, YU Yong, CHEN Bo, ZHENG Tianling
2007, (4): 93-103.
Abstract:
A set of 27 marine planktonic bacteria isolated from the polar regions was characterized by 16S rDNA sequencing and physiological and biochemical testing. More than half of these bacteria were positive for caseinase, gelatinase and β-glucosidase, and...
Circadian rhythms in the growth and reproduction of the brown alga Undaria pinnatifida and gametogenesis under different photoperiods
ZHANG Zhihuai, PANG Shaojun
2007, (4): 104-111.
Abstract:
Circadian growth rhythm of the juvenile sporophyte of the brown alga Undaria pinnatifida was measured with the computer-aided image analysis system in constant florescent white light under constant temperature (10℃). The growth rhythm persisted for 4...
