The massive earthquake off the northern Sumatran coast (Indonesia) on December 26, 2004 produced the largest trans-oceanic tsunami. Besides landform destruction and changes, the alterations produced the phenomena of aquatic environments, highlighting that ecosystem responses are also important. In this paper, we present pre-and post consequences of the tsunami on spatial and temporal distribution of Chlorophyll-a (Chl-a), the vital element of marine ecosystem and primary production. Our analysis based on satellite data (MODIS) ...

The oceanic currents in the South China Sea (SCS) are strongly influenced by monsoon winds. A review on the SCS currents has indicated that previous studies have pointed out an anticyclonic circulation in the area between the southern Vietnam coast and the Spratly Islands. However, its detail is not understood because of less information of in situ observations. The physical-biological interaction is quite new research area, which has been established and promoted by means of the ocean color remote sensing. Temporal/spatial variability of the phytoplankton activities are well captured by ocean color (OC) -derived Chlorophyll-a images. Combining the OC-Chl-a and the other high-resolution satellite data (e.g., SST images), the biological aspects of oceanographic variation is well described. The blooming phenomena in the area between the southern Vietnam coast and the Spratly islands are further investigated. Change in the wind-system related to the El Nino generates upwelling/SST-cool...

The Gulf of Tonkin is a semi-closed gulf northwest of the South China Sea, experiencing reversal seasonal monsoon. Previous studies of water conditions have been conducted in the western waters of the gulf, but very few studies of the Chlorophyll-a (Chl-a) distribution have been carried out for the entire gulf. The present study investigates seasonal and spatial distributions of Chl-a and water conditions in the Gulf of Tonkin by analyzing Sea-viewing Wide Field-of-View Scanner (SeaWiFS) derived Chlorophyll-a (Chl-a), in situ measurements, sea surface temperatures (SST), and other oceanographic data obtained in 1999 and 2000. The results show seasonality of Chl-a and SST in the Gulf of Tonkin, and reveal phytoplankton blooms in the center part of the gulf during the northeast monsoon season. In summer, Chl-a concentrations were relatively low (< 0.3 mg m-3) and distributed uniformly in the most area, with a belt of higher Chl-a concentrations along the coast, particularly the coa...

The 1800 megawatt Daya Bay Nuclear Power Station (DBNPS), China's first nuclear power station, is located on the coast of the South China Sea. DBNPS discharges 29 million m3 y -1 of warm water from its cooling system into Daya Bay, which could have ecological consequences. This study examines satellite sea surface temperature data and shipboard water column measure ments

This study implemented the validation of SeaWiFS derived Chl-a in Vietnam waters using 58 insitu measurements by SEAFDEC cruise in May 1999. Monthly mean SeaWiFS-derived Chl-a in May 1999 was used for match-up analysis with insitu measurement. Result of regression found that highly correlated between insitu and SeaWiFS-derived Chl-a. Correlative equation is y = 0.6322x - 0.3209, the root square

Analysis of satellite remote sensing data has revealed changes in distribution of chlorophyll-a (Chl-a) and sea surface temperature (SST) in the Indian Ocean during the South Asian tsunami in December 2004. Chl-a data derived from Moderate Resolution Imaging Spectroradiometer (MODIS) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS) images were examined for the period from 1998 to 2005.

The diurnal sea surface temperature (D-SST, which is the daytime SST minus the night-time SST) and its relationship with heavy phytoplankton blooms were observed using satellite and in situ data. Two phytoplankton bloom events covering large areas in the East China Sea (ECS) were analysed to investigate the reactions among D-SST, chlorophyll-a (chl-a) concentration, suspended sediment (SS), coloured dissolved organic
