Meso-scale available gravitational potential energy in the world oceans
FENG Yang, WANG Wei, HUANG Ruixin
2006, (5): 1-13.
Abstract:
The pitfalls of applying the commonly used definition of available gravitational potential energy (AGPE) to the world oceans are re-examined.It is proposed that such definition should apply to the meso-scale problems in the oceans, not the global sca...
Impacts of TRMM SRR assimilation on the numerical prediction of tropical cyclone
MA Leiming, QIN Zenghao, DUAN Yihong, LIANG Xudong, WANG Dongliang
2006, (5): 14-26.
Abstract:
Impacts of the four-dimensional variation (4DVAR) assimilation of Tropical Rainfall Measuring Mission (TRMM)/TMI surface rainfall rate (SRR) on the initialization and simulation of TC Danas in 2001 are studied.A number of sensitivity experiments are ...
Multifractal filtering method for extraction of ocean eddies from remotely sensed imagery
GE Yong, DU Yunyan, CHENG Qiuming, LI Ce
2006, (5): 27-38.
Abstract:
Traditional methods of extracting the ocean wave eddy information from remotely sensed imagery mainly use the edge detection technology such as Canny and Hough operators.However, due to the complexities of ocean eddies and image itself, it is sometim...
Organic carbon and nitrogen isotopes in surface sediments from the western Arctic Ocean and their implications for sedimentary environments
CHEN Zhihua, SHI Xuefa, CAI Deling, HAN Yibing, YANG Zuosheng
2006, (5): 39-54.
Abstract:
Surface sediments from the Chukchi Sea and adjacent arctic deep sea were investigated for organic carbon and nitrogen isotopes (in δ13Corg and δ15Norg) as well as biogenic silica (BSiO2).δ13Corg and δ15Norg values of surface sediments in the study ar...
Bohai crude oil identification by gas chromatogram fingerprinting quantitative analysis coupled with cluster analysis
SUN Peiyan, BAO Mutai, GAO Zhenhui, LI Mei, ZHAO Yuhui, WANG Xinping, ZHOU Qing, WANG Xiulin
2006, (5): 55-62.
Abstract:
By gas chromatogram, six crude oils fingerprinting distributed in four oilfields and four oil platforms were analyzed and the corresponding normal paraffin hydrocarbon (including pristane and phytane) concentration was obtained by the internal standa...
Inversion of teleseismic waves at Shidao Seismographic Station
RUAN Aiguo, LI Jiabiao, HAO Tianyao, WU Qingju, XU Yi
2006, (5): 63-73.
Abstract:
Teleseismic datasets at the Shidao Seismographic Station, located in the northwestern South China Sea, are used to determine the earth anisotropy and the vertical distribution pattern of the shear wave velocity by inversion approaches.The rotated cor...
Model study on Bohai ecosystem 2.Annual cycle of nutrient-phytoplankton dynamics
LIU Hao, YIN Baoshu
2006, (5): 74-91.
Abstract:
Using the coupled bio-physical model described in the first paper of this series of studies, the annual variations of algae biomass and nutrient concentration in the Bohai Sea are simulated.Modeled results show that the onset of spring bloom is induc...
Taxonomic composition,abundance and biomass of mesozooplankton in the Zhelin Bay-an estuary with intensive aquaculture
DONG Qiaoxiang, LIN Xiaoping, HE Xin, KELSO W E, HUANG Changjiang
2006, (5): 92-111.
Abstract:
The Zhelin Bay is an estuary that supports intensive aquaculture in South China.Aside from traditional nutrient inputs derived from waste water and agriculture, the increased intensification of aquaculture has accelerated eutrophication during the pa...
Distribution pattern of pelagic amphipods and its affecting facors in the East China Sea
XU Zhaoli, JIANG Mei
2006, (5): 112-119.
Abstract:
On the basis of data from four seasonal cruises in the East China Sea (23°30'~33°N, 118°30'~128°E) from 1997 to 2000, horizontal distribution of amphipods, seasonal variations of abundance and their dynamic mechanisms were approached with quantitativ...
Meiofauna distributions at the oxygen minimum zone in Changjiang (Yangtze) River Estuary waters
HUA Er, ZHANG Zhinan, ZHANG Yan
2006, (5): 120-134.
Abstract:
A quantitative study on meiofauna was carried out along a transect throughout the Changjiang Estuary's oxygen minimum zone (OMZ) in the East China Sea.There exist two distinct station groups in the OMZ:the fine-grained hypoxic area and the more fine-...
In vitro acute cytotoxicity of the neonicotinoid insecticide acetamiprid to FG cells, the gill cell line of flounder Paralichthy olivaceus
SU Feng, ZHANG Shicui, YANG Ming, LI Hongyan
2006, (5): 135-140.
Abstract:
The in vitro acute cytotoxicity of the neonicotinoid insecticide acetamiprid to FG cell line, derived from the gill of flounder Paralichthys olivaceus, was tested by the three widely used endpoint bioassays-neutral red (NR) assay, tetrazolium (MTT) a...
Effects of dietary vitamin A on antioxidant responses of abalone Haliotis discus hannai Ino
FU Jinghua, ZHANG Wenbing, MAI Kangsen, FENG Xiuni, XU Wei, LIUFU Zhiguo, TAN Beiping
2006, (5): 141-150.
Abstract:
A 240 d growth experiment was conducted in a re-circulated water system to investigate the effects of dietary vitamin A on growth and antioxidant responses of abalone Haliotis discus hannai Ino.Triplicate groups of juvenile abalone[initial mass was (...
Pedigree tracing of Fenneropenaeus chinensis by microsatellite DNA markers genotyping
DONG Shirui, KONG Jie, ZHANG Qingwen, LIU Ping, MENG Xianhong, WANG Rucai
2006, (5): 151-157.
Abstract:
Two microsatellite DNA loci were used to trace the pedigree structure of six families in the shrimp Fenneropenaeus chinensis.Four of the families were natural mating, and the others were mated by artificial insemination.Eleven alleles were acquired a...
