| Abstract: | Total organic carbon(TOC), CaCO3, total nitrogen (TN), particulate organic carbon(POC) and grain size in surface sediments of the western Taiwan Strait were analysed in 2005. TOC and CaCO3 contents varied in the ranges of 0.01~1.79 and 0.11~23.00 respectively. The average content of TOC in the surface sediments was 0.37±0.24 which larger than the TOC in the Southern Taiwan Strait ,but smaller than the TOC in the center and north of Taiwan Strait in 1980s. High level of TOC content was found near-shore and decreased seaward. Region with high and low value of CaCO3 had the scattering features. The average ratio C/N which indicated the mixed sources of organic materials was 10.12. The background relationship between TOC and TN was close. The power correlation between OC and grain size was suggested that grain size was a limiting factor for TOC. But there was not a good relation between grain size and CaCO3. TOC in sediment was not coupled with primary production in water in or around the upwelling area of the southern Taiwan Straint. After calculation, burial fluxes of carbon was 105 t/a in the sediments of the western Taiwan Strait. The terrestrial input, coastal current and upwelling significantly influenced the burial fluxes of carbon in the sediment. |
