The summer 2002 and winter 2003 sampling campaigns planned in El Meleh, Tunisia (pictured above) and Nador lagoon in Morocco were organized as part of the EU FP5 funded COLASU project. Both campaigns exceeded expectations, with many more samples collected compared to what was originally foreseen to be collected over the entire project duration. The analytical protocol included the chemical analyses of all sediments and soils samples together with micropaleontological and organic studies in selected samples, as well as, chemical analyses and in situ hydrological parameter measurements for water.
