Abstract
STF80MK S05016The Nordtest methodology for Oil Spill Identification has over the past 15 years formed an important ""platform"" for solving oil spill identification in many countries worldwide. The recent revision of the Nordtest Methodology (presented e.g. at AMOP, 2002) has refined the Nordtest methodology into a technically more robust and defensible oil spill identification methodology. The approach has been to make more systematic use of diagnostic ratios and data treatment/interpretative tools.
