Why does sediment collect on the floor of the Bering Sea?

Sediment collects on the floor of the Bering Sea primarily due to the erosion of the surrounding shores, which contributes enormous quantities of material to the sea annually. While surface plant and animal life also produce sedimentary material, very little of it reaches the bottom, making land-based erosion the dominant source.1

In addition to fine sediments, the bottom ooze contains significant amounts of boulders, pebbles, and gravel. These materials are torn from the shores by ice and subsequently transported out to sea. In the southern portion of the Bering Sea, the sediments are further enriched by material of volcanic origin.1
