Vertical distribution of chlorophyll a fluorescence and its response to temperature and salinity near Taiwan Bank in summer

According to the investigation data obtained during July-August,2004 in the adjacent waters around the Taiwan Bank,the relationships between chlorophyll a fluorescence and temperature,salinity were discussed.The results showed that temperature and salinity had a strong impact on the vertical distribution of chlorophyll a fluorescence.Thermocline and halocline controlled the stratification of chlorophyll a fluorescence in the nearshore area to the west of Taiwan Bank.A single peak of fluorescence appeared in the thermocline and halocline on the shelf slope of the southern shoal due to strong upwelling water.The vertical distribution of fluorescence was uniform due to strong hydrodynamic force on the Taiwan Bank,while the fluorescence showed linear relationships with temperature and salinity on the edge of the shoal as a mixing result of upwelling water and strong tide on the shoal.
