Marine National Facility 2006 Program

RV Southern Surveyor voyage 200601 conducted research in the Timor Sea off Darwin 20th January - 14th February

Chief Scientist: Dr Matthias Tomczak (Flinders University of South Australia)

Scientific Objectives
In this voyage the RV Southern Surveyor will be deployed as part of a large experimental campaign carried out in the Darwin are the Tropical Warm Pool International Cloud Experiment(TWP-ICE, see
In the context of this experiment the ship will fulfil four major roles, which are linked to the overall experiment objectives of TWP-ICE. Dr Christian Jakob will be the coordinating Chief PI of the deployment, while Dr Matthias Tomczak will be the Chief Scientist aboard the vessel. The other PIs are directly linked to the tasks below.

  1. To serve as a base for a second cloud and radiation observatory similar to the land-based ARCS site through the deployment of the Pacific Northwest National Laboratory (PNNL) Atmospheric Remote Sensing Laboratory (PARSL) and the Marine Atmospheric Emitted Radiation Interferometer (M-AERI) on the vessel away from direct land boundary effects (PI: Mather, Minnett)
  2. To extend the radiosonde observation network over the open ocean and thereby provide a critical link in closing the network around Darwin (PI: Bradley, Reynolds)
  3. To provide observations of surface meteorology, air-sea fluxes and precipitation (PI: Bradley, Reynolds)
  4. To provide measurements of the ocean state to support both ocean and coupled modelling (PI: Tomczak)

FR 02/2001

M Tomczak (Flinders University) During research voyage FR02/2001 R/V Franklin will use its SeaSoar in a study of small scale mixing processes in the Subtropical Front south of Australia.
There are four principal objectives:
1.To determine the relationship between thermohaline structures and density compensation in the Subtropical Front.
2.To determine the influence of density compensation on vertical mixing.
3.To determine the influence of changing surface wind stress on horizontal advection and vertical mixing.
4.To determine the temporal scales of interleaving events in the Subtropical Front.
FR 10/98

M. Tomczak (Flinders University) Franklin voyage FR 10/98 was the second of two research cruises to study seasonal variability of the position and intensity of the Subtropical Front south of Australia, in the region of the Great Australian Bight and the west and south coasts of Tasmania. Voyage objectives included to study the persistence and regional continuity of the Front, to determine the associated seasonal variation in temperature gradient, velocity field, transport across it, and to determine the continuity of transport from the eastern Indian Ocean to the Tasman Sea. The previous related cruise was voyage FR 02/98.
FR 02/98

M. Tomczak (Flinders University) Cruise FR 02/98 was undertaken for Subtropical Front temperature and transport studies (cruise 1 of 2). The aims of this first cruise of two (FR 10/98), being in the summer season is to: verify or refute the permanent existence and regional continuity of the Subtropical Front south of Australia; determine the seasonal variation in position and magnitude of the sea surface temperature gradient across the Subtropical Front south of Australia and in the Tasman Sea; estimate the velocity field and associated transport of the Subtropical Front; and determine the continuity of transport from the east Indian Ocean to the Tasman Sea. Survey methods included thermosalingraph and ADCP transect from Gulf St. Vincent to 40 degrees S, 118 degrees E, SeaSoar transects across the Subtropical Front, each on average 300 km long, CTDs and underway instrumentation. Recovery of two shallow current meter moorings from the shelf off western Tasmania was also conducted.
FR 10/94

M. Tomczak (Flinders University) Cruise FR 10/94 forms part of the World Ocean Circulation Experiment (WOCE). This cruise was undertaken to determine the movement of Antarctic Intermediate Water and Indian Central Water in the Great Australian Bight and possible exchange between the Pacific and Indian Oceans in the depth range of these water masses. To investigate the flow of Antarctic Bottom Water through the Australian-Antarctic Discordance. Three sections extending meridionally to 48 degrees S along 120 degrees 42'E, zonally along 48 degrees S to 132 degrees E and meridionally along 132 degrees E to form a closed box with the Australian south coast were completed. Survey methods included ADCP, CTDs and underway instrumentation. Data and water samples were collected for on board and laboratory analysis.
FR 08/94

M. Tomczak (Flinders University) including other Pis Cruise FR 08/94 was undertaken to study ocean transport in the Leeuwin Current and in the equatorial Indian Ocean. Cruise objectives included to determine the seasonal variability of the Leeuwin Current near 20 degrees S and thus the variability in southward oceanic heat flux near north-western Australia, by measuring the current's transport and water mass characteristics using current meters (an Australian contribution to WOCE); to measure the transport in the equatorial current system at 80 degrees E using current meters and to determine the depth averaged water velocity in the Leeuwin Current near 20 degrees S by measuring the magnetic and electric field fluctuations associated with it, using ocean floor magnetometers and electrometers. Other survey methods included ADCP, CTDs, Pegasus drops and underway instrumentation. Data and water samples were collected for on board and laboratory analysis.
FR 08/89

M. Tomczak (University of Sydney) including other PIs Cruise FR 08/89 was undertaken to investigate the structure of the Bass Strait water outflow and the associated undercurrent along the eastern Australian continental slope between Bass Strait and Jervis Bay, NSW. To study the distribution of pelagic birds in relation to surface zones, continental shelf, latitude and time of year. Survey methods included CTD casts, XBTs, Bunyip and underway instrumentation. Samples and data were collected for on board analysis and laboratory study. Bird observations were recorded, along with coordinates, ocean depth, and temperature and salinity of surface water. Trials were also conducted to test the micro-turbulence sensors on the Bunyip microfish towed body and extensive analysis of the data will be conducted in Hobart before the success of the modifications can be judged.
FR 11/88

M. Tomczak (University of Sydney) including other Pis Cruise FR 11/88 was undertaken to determine the location of the Subtropical Convergence (STC) between Australia and New Zealand in the Tasman Sea and to develop an indicator for the position of the STC which can be derived from satellite data. STC was located at 47 degrees south-east of Tasmania, 150 degrees east and it appeared to weaken and disintegrate as it reached the west coast of New Zealand at about 45 degrees south. The influence of the STC on the distribution and activity of sea birds was also studied. Survey methods included CTD casts, ADCP and other associated instrumentation. Water samples for iodine species analysis were collected from a 24 Niskin bottle CTD cast at 43 deg. S, 158 deg. 16' E.
FR 04/86

M. Tomczak (University of Sydney) Cruise FR 04/86 was undertaken to determine the path of the high salinity Subtropical Lower Water into and within the Coral Sea and to survey a 56 m shallow at about 25.5 degrees S, 159 degrees E near Cape Bank for the Hydrographer of the Navy. The first of the planned CTD sections were cancelled due to cyclone Namu and also the planned survey near Cape Bank due to loss of time for refuelling stop. Work completed and data acquired included CTD sections and underway data. Water samples and data were collected for on board and laboratory analysis.
