Data Trawler - Survey Details

SS 07/2008 (alternative identifier: SS200807)    - is a Marine National Facility voyage

Period: 2008-04-30 00:00 to 2008-06-07 00:00 UTC

Duration: 38.00 days

From: Noumea To: Suva

Region: South West Pacific Ocean

Ship: Southern Surveyor [details]

Description: Scientific Objectives
The fastest spreading backarc region on Earth forms the northern Lau Basin (NLB), and is the strongest source of mantle-derived 3He-rich hydrothermal plumes in the southwestern Pacific. Following Southern Surveyor NoToVE voyage (SS11/04) to the northern Tofua arc-Fonualei Rifts (Tonga) system, and ... the first Leg of SS07/2008, we propose to survey the bathymetry, magnetic characteristics, petrology, hydrothermal activity, and hence origins and evolution of ..(this regeon)... which are essentially unstudied. ....
Following high resolution 30 kHz multibeam bathymetric surveys, vertical CTD hydrocasts and tow-yos coupled with rock (glass) dredging will be used to sample along/across-strike of the spreading centres. Post-voyage laboratory 3-D magnetisation inversions ...[to]... identify mantle sources likely including Pacific- and Indian-type mid-ocean ridge and Samoan plume components, and hence obtain insights into upper mantle flows.
In the 2nd Leg we will extend the area of exploration planned for SS07/2008 to the Peggy Ridge, a leaky transform linking spreading centres in the southeastern Lau Basin with the NWLSC and Futuna Spreading Centre to the north of Fiji. We will use the same approach as in the first Leg using high resolution 30 kHz multibeam surveys, hydrocasts and tow-yos coupled with dredging to sample along and adjacent to the Peggy Ridge. Post-voyage laboratory laboratory studies will use the same techniques and pursue the same objectives as in the Ist leg.
