Diatom ooze–A large marine mercury sink

The role of algae for sequestration of atmospheric mercury in the ocean is largely unknown due to the lack of marine sediment data. We estimated Holocene global mercury accumulation in biogenic siliceous sediments (diatom ooze) based on high resolution cores from marine Antarctica. Diatom ooze exhibits the highest mercury accumulation rates ever reported for the marine environment and provided a large sink of anthropogenic mercury, surpassing existing model estimates up to seven fold. Anthrop…
