Data Trawler - Survey Details

SS 08/2006 (alternative identifier: SS200608)    - is a Marine National Facility voyage

Period: 2006-08-19 01:00 to 2006-09-10 21:00 UTC

Duration: 22.83 days

From: Suva To: Noumea

Region: SW Pacific Fiji - Vanuatu

Ship: Southern Surveyor [details]

Description: Southern Surveyor voyage SS08/2006.
Voyage Objectives:
We intend to conduct a multibeam survey, a magnetics survey and rock sampling in three areas along the Hunter Ridge. The questions which we are seeking to answer are as follows:
Kadavu and northern Hunter Ridge (area 1)
Questions:
1) What is the lateral extent of adakites on the seafloor around Kadavu Is?
2) What is the structural relationships between the northern Hunter Ridge and Kadavu Island?
To answer these questions we plan to do detailed swath mapping, sound-bottom profiling and dredge sampling in area 1. The use of the soundbottom profiler will be vital in determining whether the seafloor has a volcanic, sediment-poor, basement or alternatively the seafloor is formed by sediments. This information will significantly help the interpretation of the swath mapping.
Rift Zone at the southern end of the Hunter Ridge (area 2)
Question:
1) What is the distribution of different magma types withinthe rift?
To answer this question we wish to perform 10-15 dredges within the main rift zone between 1500-2500m water depth.
North Fiji Basin propagating spreading centre (area 3)
Question:
1) What is the age and rate of southward propagation of the spreading centre?
We plan to conduct a magnetic survey along 3 lines across the spreading ridge to obtain magnetic profiles. Due to the limited time during voyage SS10/2004 to conduct a detailed sampling of the spreading centre, we plan to do further sampling using a specially modified piston corer, designed for sampling glassy pillow rinds of young lavas.
