Particle Flux in the Western Black Sea in the Present and over the Last 5,000 Years: Temporal Variability, Sources, Transport Mechanisms.

Abstract

The particle flux in the present and over the last 5,000 years was investigated in the western Black Sea in a comparative study with samples from time-series sediment traps and laminated core sediments. The particle flux varies considerably seasonally and regionally. Dominant particle sources are biogenic and terrigenous matter. The relative importance in the particle supply varies seasonally and can be grouped into three phases: Phase I (June-October; coccolithophorid production); Phase II (November-January; resuspension of shelf deposits); and Phase III (February-May; river input of terrigenous matter and diatom production). Keywords: Hemipelagic sedimentation.
