SS 11/2004 (alternative identifier: SS200411)    - is a Marine National Facility voyage

Period: 2004-10-26 21:00 to 2004-11-15 20:00 UTC

Duration: 19.96 days

From: Nuku'alofa To: Apia

Region: the northern Tofua Arc, Pacific Ocean, Coral Sea

Ship: Southern Surveyor [details]

Description: Voyage SS 11/2004, NOTOVE-2004 (Northern Tonga Vents Expedition) will continue to investigate the Submarine hydrothermal plume activity and petrology of the northern Tofua Arc, Tonga, complimenting the work of SS 02/2003.
Specific objectives are:
1. To perform the first detailed, high-resolution, swathmap bathymetric surveys of individual submarine volcanoes of the northern Tofua Arc between 20o 50'S and 15o 20'S, using the Kongsberg EM300 system; 2. To perform the first detailed, high-resolution swathmap bathymetric survey of the Fonualei Rifts, a nascent backarc basin immediately adjacent and northwest of Fonualei; 3. Dredge igneous rock targets identified on these submarine volcanoes, and the floor of the Fonualei Rifts, in order to recover fresh glassy rock samples for detailed age studies and chemical analysis, particularly of volatile elements and compounds, radiogenic and stable isotopic characteristics. 4. Dredge hydrothermal sulfide-rich and altered rock samples for studies of base and precious metal mineralisation; 5. To explore with the transmissometer/nephelometer-equipped CTD rosette for hydrothermal plume activity in these volcanoes and rifts, and to recover water samples for immediate analysis on board and subsequent shore-based laboratory analysis.
