Following the second transnational meeting in Brest, environmental conditions and oils to be weathered in the flume were defined according to the data obtained for each site. The objective of these tests was to provide modelers with realistic data in order to calibrate their models. As regards the heavy oil (IFO 220), 7 tests were scheduled considering three levels for each parameter (energy, salinity and temperature): a minimum, a maximum and an average. In addition to the central point, 6 tests had to be conducted considering an extreme (minimum or maximum) for each of the 3 other parameters. As regards the diesel oil, only two tests considering the minimum and maximum of energy had to be performed. By the end of February, 5 tests were completed for the IFO 220 and one for the diesel oil. The last two experiments should be conducted in April.
