Early diagenetic redistribution and burial of phosphorus in the sediments of the southwestern East Sea (Japan Sea)

The burial flux of reactive P (iron oxide-bound P+authigenic P+organic P) is 0.09-0.53 g P m−2 yr−1 that accounts for 18-58% of the reactive P arriving at the sediment/water interface. The burial flux of reactive P is high in the upper and lower continental margin sediment. The burial flux of reactive P in the Ulleung Basin sediment is less than those in the continental margin sites by a factor of 6, indicating that the reactive P burial flux is mainly dependent on sedimentation rate.
