Abstract:
A reduced vertically integrated upper mixed layer model is set up to numerically study the thermodynamic process of the formation of the "Nansha warm water"(NWW) in the Nansha Islands sea areas in spring. According to the numerical experiments, it is...
Application of the HY-1 satellite to sea ice monitoring and forecasting
LUO Yawei, WU Huiding, ZHANG Yunfei, SUN Congrong, LIU Yu
2004, (2): 251-266.
Abstract:
The HY-1A satellite is the first oceanic satellite of China. During the winter of 2002-2003, the data of the HY-1A were applied to the sea ice monitoring and forecasting for the Bohai Sea of China for the first time. The sea ice retrieval system of t...
On the relationship between convection intensity of South China Sea summer monsoon and air-sea temperature difference in the tropical oceans
LIN Ailan, LIANG Jianyin, GU Dejun, WANG Dongxiao
2004, (2): 267-278.
Abstract:
The annual, interannual and inter-decadal variability of convection intensity of South China Sea (SCS) summer monsoon and air-sea temperature difference in the tropical ocean is analyzed, and their relationship is discussed using two data sets of 48-...
Dissolved inorganic carbon and CO2 fluxes across Jiaozhou Bay air-water interface
LI Xuegang, LI Ning, GAO Xuelu, SONG Jinming
2004, (2): 279-285.
Abstract:
On the basis of data collected in the Jiaozhou Bay in June and July 2003, the DIC distribution in seawater is studied, and an average air-sea flux of CO2 is estimated. The results show that the content of DIC inside the bay is markedly higher than ou...

LIU Yanguang, MENG Xianwei, FU Yunxia
2004, (2): 287-296.
Abstract:
Hydrothermal chimney is a product of hydrothermal activity on the seabed. Chimney samples dredged from Jade hydrothermal area in Izena depression of the Okinawa Trough, are characterized by relatively enriched light rare earth elements (LREE) and str...
Indicators and impact analysis of sediment from the Changjiang Estuary and East China Sea to the Hangzhou Bay
