9 April 2001: Plans for the 11th Training-Through-Research Cruise ITEM: 011
1. Name of the research ship: RV Professor Logachev 2. Cruise dates: 18.07.2001 - 10.09.2001 3. Operating authority and owner: State Enterprise "Polar Marine Geosurvey Expedition", 24 Pobeda St., 189510 St. Petersburg, Russia, tel: +7 812 4220494 4. Particulars of ship:
5. Crew: master: Alexander B. Arutyunov, number of crew: 33 6. Co-chief scientists:
7. Geographical areas in which the ship will operate:
8. Purpose of the cruise: Studies of geological processes in the Black and Mediterranean Seas and on the North East Atlantic margin - the 11th international ‘Floating University’ expedition of the UNESCO/IOC Training-trough-Research Programme with research and training purposes. Scientists and students who have already expressed their interest in joining the cruise are from: Brazil, Greece, Morocco, the Netherlands, Portugal, Russia, Spain, Turkey, the UK and the Ukraine. 9. Intended ports of call:
10. Purpose of research and general operational methods: The principle purpose of the cruise will be to study geological processes, such as bottom current activity, slope processes, mud volcanism, neo-tectonics, manifestations of shallow gas, etc. in the Black and Mediterranean Seas and on the North East Atlantic margin, as well as to train students from Western Europe, Northern Africa, Brazil, the Ukraine and Russia in marine research. In the Black Sea, the cruise will be focussed on mud volcanism, manifestation of shallow gas and related phenomena, such as sub-bottom gas hydrate occurrence, diagenetic mineralisation, and chemosynthetic biological communities. The phenomenon of mud volcanism, in relation with local fluid and tectonic regime, will also be investigated in the Cobblestone-3 field of the Ionian Sea and in the Gulf of Cadiz, following previous TTR studies in these areas. In the Aegean Sea, the scientific aim is to investigate the westward extension and propagation of the North Anatolian Fault into the N. Aegean and its transition from a strike-slip/ transtensional to extensional deformation towards Greece. A debris flow at the Ebro continental slope and rise, within the Valencia Gulf, off the Columbretes Islets will be acoustically and optically mapped and, eventually, sampled. Sedimentological, geochemical and oceanographic processes related with ferromanganese deposits and phosphorites, occurring on the Ampère, Lion and Seine seamounts, located between the Portuguese coast and Madeira Island will be investigated. Because of their marginal position to the abyssal area of the Atlantic, it is subject to the influence of upwelling of oceanic waters. We also want to find out whether any remaining influence of the Mediterranean Water can be identified there. The cruise has the potential to improve the scientific knowledge on some outstanding problems in the field of geological and geochemical processes in the Black and Mediterranean Seas and on the North East Atlantic margin, and at the same time is aimed to provide advanced on-the-job training for students and young scientists from different countries. The research methods to be used are as follows:
