dc.description.abstract This study investigated organic carbon fluxes in Ulleung Basin sediments, East Sea based on a chamber experiment and geochemical analyses. At depths greater than 2,000 m, Ulleung Basin sediments have high organic carbon contents (over 2.0%). Apparent sedimentation rates (ASR) calculated from excess 210Pb activity distribution, varied from 0.036 to 0.047 cm yr-1. The mass accumulation rates (MAR) calculated from porosity, grain density (GD), and ASR, ranged from 131 to 184 g m-2 yr-1. These results were in agreement with sediment trap results obtained at a water depth of 2100 m. Input fluxes of organic carbon varied from 7.89 to 11.08 gC m-2 yr-1 at the basin sediments, with an average of 9.56 gC m-2 yr-1. Below a sediment depth of 15cm, burial fluxes of organic carbon ranged from 2.02 to 3.10 gC m-2 yr-1. Within the basin sediments, regenerated fluxes of organic carbon estimated with oxygen consumption rate, varied from 6.22 to 6.90 gC m-2 yr-1. However, the regenerated fluxes of organic carbon calculated by subtracting burial flux from input flux, varied from 5.87 to 7.98 gC m-2 yr-1. Respectively, the proportions of the input flux, regenerated flux, and burial flux to the primary production (233.6 gC m-2 yr-1) in the Ulleung Basin were about 4.1%, 3.0%, and 1.1%. These proportions were extraordinarily higher than the average of world open ocean. Based upon these results, the Ulleung Basin might play an integral role in the deposition and removal of organic carbon. -
