Leg 1 (11-23 June) was carried out in the Alboran Sea (Western Mediterranean) and Leg 2 (23 June-4 July) in the Gulf of Cadiz. These legs studied ecological hotspots. Afterwards the RV Professor Logachev moved to the north. Leg 3 was carried out on the Norwegian margin (12-24 July). Its main objective was to collect data needed for developing depositional models for Cenozoic sandy systems in order to better identify and quantify factors critical to reservoir rock occurrence and distribution.
