Analysis of relict turbidite in the Madeira abyssal plain reveals the usage of pollen grains in the marine sediments as an effective tracer of oxygen-sensitive organic carbon. Oxic degeneration of pollen grains in coastal sediments explains the reduction of organic carbon with depth. The role of pollen degradation in the oxygen-sensitive degeneration of organic matter is vital for the regulation of atmospheric oxygen concentrations over geological time.
