Data Trawler - Survey Details

SS 01/2009 (alternative identifier: SS200901)    - is a Marine National Facility voyage

Period: 2009-02-02 21:00 to 2009-03-23 22:00 UTC

Duration: 49.04 days

From: Wellington To: Suva

Region: Pacific Ocean

Ship: Southern Surveyor [details]

Description: Monitoring Ocean Climate Change Around Australia: Deep Ocean Time Series Section (DOTSS) along 170oW between 50oS and the Equator.
Scientific Objectives
This project will monitor deep ocean changes via Deep Ocean Time Series Sections (DOTSS) which is Australia's contribution to the International Repeat Hydrography and Carbon Program. Specifically we will reoccupy a full depth ocean section in the Pacific along 170oW from 50oS to the equator with the aim to maintain full depth, high precision hydrographic, carbon and tracer measurements along key sections in the oceans surrounding Australia to monitor circulation and biogeochemical changes on multi-decadal timescales. Station spacing along the section will average about 30nm from 50°S to the equator with close spacing over steep topography.
Voyage Objectives
The voyage objectives will be met by undertaking full depth CTD and Niskin bottle casts that measure salinity, temperature and pressure continuously and the major nutrients discretely. We will be relying on achieving International standard (WOCE) accuracy in order to measure what might be small but significant changes at depth. Water samples (24 per cast) collected by niskin bottles at discrete depth in the water column, will be analysed on board for the full suite of nutrients, dissolved inorganic carbon concentrations (DIC) and alkalinity. Samples will also be collected for carbon isotope analyses. Through collaboration with the PMEL and the University of Washington we will be able to measure concentrations.In addition to the standard rosette, shipboard ADCP will deliver underway direct estimate of velocity data along the cruise track. At the direction of the Chief Scientist the CTD/Rosette will be reconfigured during the voyage to include the LADCP for full water column velocity profiles.
The SS 1/2009 voyage will be divided into two legs with port call at Nuku'alofa, Tonga.
