Physical oceanography

Investigator has a wide range of equipment to support physical oceanography including CTD systems with 24 and 36 bottle sampling rosettes, two acoustic transducers to measure ocean currents, on board chemical, biological, and biogeochemical laboratories fitted with general purpose clean and trace metal clean seawater outlets.

There is a suite of winches for the support of towed CTD systems (Triaxis and tow-yos), subsurface pumped water sampling systems and other user supplied instruments.

The vessel can deploy and retrieve moorings, sediment traps and free-floating instruments.

The oceanographic systems are integrated with the atmospheric measurements to provide better estimates of air-sea heat fluxes and carbon dioxide fluxes, into and out of the ocean.

The biological and biogeochemical oceanography systems are diverse with the measurements complementing each other.

Please refer to the general overview for items not specific to a discipline.

The following equipment is usually available:

  • Acoustic Doppler Current Profilers (ADCP)  – RDI Ocean Surveyor 75 & 150 kHz ADCP
  • Laboratory clean containers – trace metal laboratory clean containers
  • Seabird Rosette 24 bottle carousel water samplers for CTD
  • Seabird Rosette 36 bottle carousel water samplers for CTD
  • Towed general purpose profiling CTD – TRIAXUS
  • Trace metal clean winch, block and rope
  • Trace metal in-situ pumps
  • Trace metal rosette – autonomous trace metal rosette and bottles (with half container for storage and transport)
