Example of pollen found at different mbsf depths in sample cores: Fischeripollis found at 148.36 mbsf (1) and at 142.50 mbsf; Periporopollenites "spinosus" ms. found at 180.40 mbsf (9 and 10).

The acronym mbsf, meaning metres below seafloor, is a convention used for depths below the seabed[1][2] used in geology, paleontology, oceanography, petrology and exploration drilling.
