An EOL Integrated Sounding System (ISS) was recently deployed on the RV Investigator, an Australian research vessel operated by CSIRO / MNF for the SOCRATES campaign. The Investigator sailed deep into the Southern Ocean from Jan 11 to Feb 22, 2018 as part of an Australian campaign known as CAPRICORN (Clouds, Aerosols, Precipitation and atmospherIc Composition Over the southeRN ocean) led by PIs from the Bureau of Meteorology. In preparation for SOCRATES the ISS took part in a shakedown and training voyage in early December off the coast of Tasmania, and preliminary plots from that voyage are also included in the summary plots page.
The ISS instrumentation included:
Radar Wind Profiler
LAP3000 915 MHz profiler
Main deck
Wind Lidar
ZephIR 300
Aft 02 deck
Ceilometer
Vaisala CL31
Aft 02 deck
Soundings
Vaisala MW41 launching RS41 radiosondes
Main deck
Basic Met
WXT520 and web camera
Aft 02 deck
A wide range of additional instrumentation was also installed on the Investigator and operated by other groups.
