RV Investigator at sea seen from the air


Investigator has a suite of instruments for atmospheric research ranging from a new generation of weather radar that can collect information within a 150 km radius around the vessel, through to instruments measuring sunlight, aerosols, cloud condensation nuclei, and other components of the atmosphere.

The research facilities on-board include two dedicated laboratories (one for aerosol and the other for chemistry) and space for two additional container laboratories on the foredeck.  The vessel is also fitted with specialised booms to operate a range of instruments near (and just below) the sea surface. The foremast is also fitted with an aerosol inlet and has the ability to mount a suite of meteorological and air-sea flux instruments that pump air directly into the two laboratories. There are also facilities for releasing weather balloons and sondes for atmospheric profiling.

Atmospheric equipment typically available on Investigator includes, but may not be limited to:

  • Absorption photometer
  • Atmospheric nephelometer
  • Dual polarization Doppler C-band weather radar
  • Greenhouse gas spectrometers
  • Meteorological instruments – wind speed and direction, air temperature and humidity, rainfall, radiation, atmospheric pressure, etc
  • NOX monitor
  • Ozone monitor
  • Radon detector
  • Sampling mast, pump and aerosol laboratory
  • Scanning mobility particle sizer
  • Sea Surface Temperature (SST) radiometer

As noted above, the vessel can also cater for a range of other atmospheric research equipment.  Some of this equipment may require specialised or additional support not typically provided on Investigator which may attract an additional charge.
