One important source of iron is wind-blown dust. The polar oceans are remote from dust sources but melting icebergs supply sediment that contains iron which is potentially available to plankton. We show that iceberg sediments contain more potentially bioavailable iron than wind-blown dust. Iceberg sources will become increasingly important with climate change and increased plankton growth can remove more carbon dioxide from the atmosphere.
One important source of iron is wind-blown Both types can be subdivided into various subfacies. Most widespread in the Northern Hemisphere is the Siberian subfacies, characterized by silt and clay and often misinterpreted as sediments of temperate zones.
This reference book for researchers working on this kind of sediments provides a complete overview of the various glacial deposits in the ocean. The book follows a clear and logical structure.

However, Shoenfelt et al. Put white paper under the box and on top of the brick so the sediment particles will be more visible when glaciers and icebergs melt. Figure 8.
