Many people contributed to the success of the research cruise (MARM10_02 R/V Urania). We are particularly indebted to the Captain Vincenzo Lubrano Lavadera, the officers and crew members of R/V Urania for their professionalism and efforts in assuring the success of the cruise. Turkish SHOD is warmly acknowledged for support and encouragement. The project was co-funded by Italian CNR and EU's ESONET.
