Long baroclinic Rossby waves with periods of about 500 d near 20°N in the northwest Pacific Ocean
CHEN Haiying, QIAO Fangli, FANG Guohong, WANG Yonggang, WEI Zexun
2006, (3): 1-10.
Abstract:
On the basis of maps of sea level anomalies data set from October 1992 to January 2004, pronounced low frequency variations with periods of about 500 d are detected in the area near 20°N from 160°W to 130°E. A linear two-layer model is employed to ex...
Decadal-to-interdecadal response and adjustment of the North Pacific to prescribed surface forcing in an oceanic general circulation model
FANG Jiabei, RONG Xinyao, YANG Xiuqun
2006, (3): 11-24.
Abstract:
The simulation of a higher-resolution oceanic GCM forced with COADS surface conditions during 1945~1993 was analyzed with insight into how the North Pacific responds to the surface forcing. The decadal-to-interdecadal variabilities in the thermal and...
Atmospheric correction of Landsat data for the retrieval of sea surface temperature in coastal waters
XING Qianguo, CHEN Chuqun, SHI Ping, YANG Jingkun, TANG Shilin
2006, (3): 25-34.
Abstract:
A mono-window algorithm was introduced to retrieve sea surface temperature (SST) using Landsat data in coastal waters. In this algorithm, the effective mean air temperature and the water vapor content of air column were estimated with the local meteo...
Neural network wind retrieval from ERS-1/2 scatterometer data
LIN Mingsen, SONG Xingai, JIANG Xingwei
2006, (3): 35-39.
Abstract:
A neural network methodology is presented to retrieve wind vectors from ERS-1/2 scatterometer data. The wind directional ambiguities are eliminated by a circular median filter algorithm. All data come from ERS-1/2 scatterometer data collocated pairs ...
Shenzhou-4 spaceborne altimeter waveform processing and significant wave height retrieval
JI Yonggang, ZHANG Jie, ZHANG Youguang, MENG Junmin
2006, (3): 40-47.
Abstract:
The Shenzhou-4 spaceborne (SZ-4) altimeter waveforms were processed, and then the significant wave heights (SWH) was retrieved on the basis of waveform fitting and waveform retracking. Waveforms processing includes the waveform 1 s averaging, the eli...
The diffusive fluxes of inorganic nitrogen across the intertidal sediment-water interface of the Changjiang Estuary in China
HOU Lijun, LIU Min, XU Shiyuan, LU Jianjian, OU Dongni, YU Jie
2006, (3): 48-57.
Abstract:
Ammonium and nitrate concentrations were analyzed in near-bottom water and pore water collected from ten stations of the intertidal flat of the Changjiang Estuary during April, July, November and February. The magnitudes of the benthic exchange fluxe...
Western fault zone of South China Sea and its physical simulation evidences
SUN Longtao, SUN Zhen, ZHAN Wenhuan, SUN Zongxun, ZHAO Minghui, XIA Shaohong
2006, (3): 58-67.
Abstract:
The western fault zone of the South China Sea is a strike-slip fault system and consists of four typical strike-slip faults. It is the western border of the South China Sea. The formation of the system is due to the extrusion of Indo-China Peninsula ...
Distributions of chlorophyll a and carbon fixed strength of phyto-plankton in autumn of the southern Huanghai Sea waters
ZHENG Guoxia, SONG Jinming, DAI Jicui, WANG Yiming
2006, (3): 68-81.
Abstract:
Chlorophyll a (Chl a) concentration and primary productivity (PP), namely, carbon fixed strength of phytoplankton along four transects in the southern Huanghai Sea (SHS) were studied for their distribution features and controlling mechanisms based on...
Assessing genetic diversity of wild populations of Japanese flounderusing AFLP markers
XU Xiaofei, ZHANG Quanqi, WANG Zhigang, QI Jie, ZHANG Zhifeng, BAO Zhenmin, Heisuke Nakagawa
2006, (3): 82-89.
Abstract:
Amplified fragment length polymorphism (AFLP) analysis was used to evaluate the genetic diversity of four wild geographical populations of Japanese flounder (Paralichthys olivaceus). A total of 775 loci (58.32% of which was polymorphic) in the range ...
Settlement and metamorphosis of Styela canopus Savigny larvae in response to some neurotransmitters and thyroxin
FENG Danqing, HUANG Ying, KE Caihuan, ZHOU Shiqiang, LI Shaojing
2006, (3): 90-97.
Abstract:
The larvae of ascidian Styela canopus Savigny were treated with epinephrine, norepinephrine, L-DOPA, GABA and thyroxin to test the ability of these compounds to induce or inhibit larval settlement and metamorphosis. The results showed that epinephrin...
Molecular phylogenetic analysis of sulfate-reducing bacteria from deep sediment layers of the tropical West Pacific warm pool
LUO Zhuhua, YE Dezan, HUANG Xiangling

Abstract:
The diversity of sulfate-reducing bacteria (SRB) from deep layers of deep-sea sediments[more than 2 m bsf (below seafloor)] of two sites (W01-3 and WP01-4) in a tropical West Pacific warm pool region was characterized by using molecular phylogenetic ...
