2006, (2): 49-62.
Abstract:
With the sea surface observations from ICOADS for the years 1960~2002, the conditions of cooling, evaporation and water vapor transportation are analyzed and compared for the formation of seasonal sea fog in April-July in the Huanghai Sea.It is found...
Classification of seamount morphology and its evaluating significance of ferromanganese crust in the central Pacific Ocean
CHU Fengyou, SUN Guosheng, MA Weilin, LI Shoujun, QIAN Xinyan, ZHAO Hongqiao
2006, (2): 63-70.
Abstract:
Using the SeaBeam technology, the morphology of seamount and its relation to the formation of cobalt-rich crust in the central Pacific Ocean were surveyed during the cruise in 2003 for marine mineral resources.The result shows that seamounts can be d...
Changjiang River sediment delivering into the sea in response to water storage of Sanxia Reservoir in 2003
CHU Zhongxin, ZHAI Shikui, CHEN Xiufa
2006, (2): 71-79.
Abstract:
The Sanxia Reservoir on the Changjiang River stored water from 1 to 10 June and from 25 October to 5 November in 2003, elevating the water level to 135 and 139 m above mean sea level at the dam, respectively.A monthly dataset of water discharge, susp...
Basic theory and key technologies for marine geographic information system
SU Fenzhen, YANG Xiaomei, XU Jun, ZHANG Tianyu, LUO Jiancheng
2006, (2): 80-86.
Abstract:
Marine geographic information system (MGIS) has great ability to deal with the spatio-temporal problems and has potential superiority when it is applied to oceanography.Using the feature extraction of oceanic phenomena as a case study, the functions ...
Studies on the species composition and biodiversity of free-living marine nematodes in the southern Huanghai Sea
HUANG Yong, ZHANG Zhinan, LIU Xiaoshou, ZHANG Yan
2006, (2): 87-98.
Abstract:
Free-living marine nematodes were sampled and studied at a grid of 22 stations (from 32°29.35' to 37°0.56'N, 122°0.37' to 125°1.16'E) in the southern Huanghai Sea in January 2003.Nematode abundance varied from 50.5 to 127.2 ind./cm2[(83.1±24.7) ind./...
Phylogenetic relationship of Podocopida (Ostracoda:Podocopa) based on 18S ribosomal DNA sequences
YU Na, ZHAO Meiying, CHEN Liqiao, YANG Pin
2006, (2): 99-108.
Abstract:
Nucleotide sequences from 18S rDNA of 11 ostracodes, which represent four suborders and six superfamilies of podocopidan, were determined.The phylogenetic relationships were analyzed based on three kinds of methods (maximum-likelihood, maximum-parsim...
Quantitative relationship between flagellate abundance and suspended particle density in Huanghai Sea and East China Sea in summer
