SS2009_V06 [details]	Professor Jason Middleton (UNSW)	Southern Surveyor research voyage ss2009_v06. Perturbation Flow Processes Over Seamounts in the East Australia Current Outflow in the Tasman Sea.
SS 09/2006 [details]	Prof J Middleton (UNSW)	Southern Surveyor voyage SS200609 Southern Surveyor research voyage SS200609 Title A comparison of nutrient supply processes and biological productivity in upwelling and frontal regions of the Lord Howe Ridge Voyage Objectives The on-board observational program will utilise the following observational equipment. (a) CTD casts at stations along transects of the Tasman Front and Lord Howe topography, using the full rosette sampler and fluorometer. We will take standard nutrients (NOx, P, Si), salinity and oxygen at up to 8 depths at each station. Transects will have casts to 300 or 500 m depth. (b) ADCP and SeaSoar profiles along transects at 8 knots. The SeaSoar will have the UNSW Optical Plankton Counter mounted. (c) Neuston net samples simultaneously with Rectangular Midwater Trawl (RMT) plankton samples from the stern. Nearly all plankton sampling will take place at night, usually between 1900-2400, but where pilchard or gemfish larvae are particularly abundant we plan to sample them during the day as well. Plankton will be preserved in 5% formalin at an appropriate location on the back deck. The first and last tows of the 3 replicates will be iced and be presorted for pilchard larvae for separate preservation in 95% alcohol. (d) Recent SST and ocean colour satellite images will be downloaded throughout the voyage to ensure transects are related to current/topography areas of interest. (e) Underway measurements of SST and fluorescence from automatic analysis of thermosalinograph intake waters. (f) a single current meter mooring will be deployed at the saddle point between Lord Howe and Balls Pyramid, for the period of a few days that the ship will be working in the region.............. Taken from unpublished Marine National Facility Voyage Plan (CSIRO 2006).
SS 08/2004 [details]	J. Middleton (UNSW)	This voyage took place between Sydney and Brisbane off the New South Wales and Queensland coast in September 2004 Voyage Objectives: Observe using the SeaSoar with an optical plankton counter, the detailed hydrodynamic structure of the front from its separation point near the coast, and to follow it into deeper waters (the Tasman Front); (Suthers & Middleton) Examine the bio-physical structure in the wake around a shelf island (the South Solitary Island); (Suthers & Middleton) To compare the zooplankton size structure with the growth of larval fish (pilchards) over a range of oceanographic conditions; (Suthers) To investigate the early life history of pilchards in the Tasman Front, in comparison with the Kuroshio extension; (Suthers) To compare these data against a size-based mechanistic model of the pelagic ecosystem (Baird, Suthers and Middleton)
FR 01/99 [details]	J. Middleton (University of NSW)	Studies of continental shelf processes, including zooplankton biomass and particle size structure in the coastal zone (up to 100m depth) See the Cruise Plan for more details.
FR 14/98 [details]	J. Middleton (University of NSW)	Studies of continental shelf processes, including zooplankton biomass and particle size structure in the coastal zone (up to 100m depth) See Cruise Plan for more details, 6pp.
FR 02/94 [details]	J. Middleton (University of NSW) including other Pis	Cruise FR 02/94 was undertaken to determine the baroclinic current structure of the coastal waters off Sydney, and the effects on the distribution of nutrients and planktonic fish. Survey methods included deployment of current meter moorings (moorings to be retrieved on FR 04/94), CTDs, ADCPs (concurrent ADCP sampling with two smaller vessels was also undertaken), SDL, EZ and surface net tows, and underway instrumentation. Data, water and biological samples were collected for on board and laboratory analyses.
FR 02/93 [details]	J. Middleton (University of NSW), including other Pis	Cruise FR 02/93 was undertaken to examine the physical and biological oceanography around two isolated reefs in the Coral Sea: Cato Reef (23 degrees S, 155 degrees E) and Wreck Reef (22 degrees S, 155 degrees E). Cruise objectives included to determine the nature of hydrodynamic processes near the reefs and their effects on the distribution of nutrients, phytoplankton, zooplankton and larval fish. Survey methods included ADCP, CTDs, EZ net tows, TUBSS (Towed Underwater Biological Sampling System) and underway instrumentation. Data, water and biological samples were collected for on board and laboratory analyses. The two current meters (deployed on cruise FR 08/92) were successfully retrieved. Related cruise FR 08/92.
FR 08/92 [details]	J. Middleton (University of NSW)	Cruise FR 08/92 was undertaken to examine the physical and biological oceanography around two isolated reefs in the Coral Sea: Cato Reef (23 degrees S, 155 degrees E) and Wreck Reef (22 degrees S, 155 degrees E). Cruise objectives included to determine phytoplankton abundance and productivity about each reef, and to relate these results to the physical measurements and to obtain EZ net and surface samples in the wake of the reefs and in the free stream during both day and night, and to relate the health and abundance of larval fish to the physical environment and primary production. Survey methods included ADCP transects, EZ net tows, CTD profiles, XBTs and underway instrumentation. Data, water and biological samples were collected for on board and laboratory analyses. In addition, one current meter mooring was deployed near Bird Island to the east and one near West Island to the west to monitor flow patterns and will be retrieved during cruise FR 02/93. Related cruise FR 02/93.
FR 09/90 [details]	J. Middleton (University of NSW)	Cruise FR 09/90 was undertaken to determine the processes responsible for scattering of coastal trapped waves around Fraser Island and the Capricorn Channel, and the tidally induced mixing processes on the continental slope near the Hydrographers Passage, in the Coral Sea, southern Great Barrier Reef region. 7 moorings with 15 current meters and 1 tide gauge (deployed on cruise FR 04/90) were recovered, 24 CTD stations were taken, 20 XBTs deployed, ADCP and underway data recorded. Samples collected included water, nutrient, fluorescence, ADCP and current meter data for on board and laboratory analysis. Related cruise FR 04/90.
FR 04/90 [details]	J. Middleton (University of NSW)	Cruise FR 04/90 was undertaken in the Coral Sea, Southern Great Barrier Reef region to determine the processes responsible for scattering of coastal trapped waves around Fraser Island and the Capricorn Channel, and the tidally induced mixing processes on the continental slope near the Hydrographers Passage. 11 moorings with 20 current meters and 2 tide gauges were deployed, 111 CTD stations were conducted, 38 XBTs deployed, ADCP and underway data recorded. Current meter data will be analysed once it has been recovered during cruise FR 09/90 and the interpretation of the CTD and ADCP data will be undertaken simultaneously. Nutrient samples were also collected for analysis in conjunction with the CTD and ADCP data. Related cruise FR 09/90.
