内容記述 | We have attempted to reconstruct the palaeoenvironment of the coastal region around Syowa Station in Lutzow-Holm Bay, Antarctica using organic compounds in a marine sediment core from this region. The vertical variation pattern of organic carbon (OC) in the sediment core was similar to that of total nitrogen (TN). The OC and TN values decreased from 0.3 to 0.02 and 0.046 to 0.004% by weight from the surface to the bottom, respectively. ^<14>C age showed a smooth pattern of change from about 3000 yBP at the surface to 14000yBP at the bottom (129cm), except for an abrupt age gap at a depth of 70cm in the sediment core. Normal-alkanes ranging from C_<15> (carbon chain length) to C_<33> were found with a predominance of C_<21> in the low hydrocarbon content sections (0.16-0.79 μg/g) at depths of 0-5, 55-60 and 120-125 cm of the core, whereas long-chain n-alkanes (C_<22>, C_<23>, C_<24>) were relatively dominant in the high hydrocarbon content sections (11.8-12.2 μg/g) at depths of 45-50 and 90-95 cm. The differences in the δ^<13>C values of the n-alkanes (C_<17>-C_<32>) analyzed by a GC-IRMS system for the high and low hydrocarbon content sections of the core (-26.0 to -28.5‰) were not appreciable, suggesting a common source of origin of these compounds. Normal-alkane distribution and the δ^<13>C values of each n-alkane indicate that the major source of these compounds is probably a mixture of marine organisms and eroded material from older sediments. | |||||
