Abstract - A summary of methodologies, technical details and ship-board results of a swath bathymetry, geophysical, geological and oceanographical survey in the Northern Red Sea is presented. The cruise utilized the CNR's R/V Urania and investigated the Deeps north of 22N. During the 14 days in the area, detailed, full coverage bathymetry, multichannel and SBP reflection seismic, magnetometric lines, bottom sediment sampling were carried out in the Thetis Deep Area. In addition, multibeam bathymetry, SBP and brine sampling in the Nereus, Oceanographer and Conrad Deeps were accomplished. The samples and data collected in the transitional area of the Northern Red Sea will give an insight on the processes that occured during the transition from a continental to an oceanic rift.

Sommario - Vengono presentati le metodologie e l'insieme dei risultati ottenuti durante una campagna di rilievi batimetrici e geofisici nella zona Nord del M.Rosso. E' stata utilizzata la nave da ricerca R/V Urania del CNR, per indagini nella zona di depressione Thetis e a N del 22N. Si e' ottenuta una mappa batimetrica dettagliata con sistema 'multibeam', sono state fatte indagini di sismica a riflessione multicanale e SBP ad alta risoluzione, sono stati raccolti dati magnetometrici ed e' stato campionato il fondo marino (Thetis) e le brine (Nereus, Oceanographer e Conrad).
