The review includes studies carried out in temperate waters throughout the world where they are relevant to understanding UK incidents. The report identifies the contribution made by IP-sponsored research and discusses its importance. Finally it draws conclusions concerning the significance of oil pollution in UK waters and suggests areas where further research would be useful.
