The figure “Slick/Dosage Parameters” in the DMP2 illustrates the relationship between
oil thickness and equivalent volumes of oil per unit area, or “Concentration”. The figure
also provides corresponding amounts of dispersant that would be needed (i.e., “dosage”)
for a given oil thickness or concentration. Any line drawn vertically through the figure
would give, for a selected average oil thickness, the corresponding volume of oil per unit
area at that average thickness, and the amount of dispersant that would be needed
(“Desired Dispersant Dosage”) for that Average Oil Thickness or Concentration.
