Scientific Instrumentation for R/V Armstrong

Shipboard Equipment

Bathymetry System 12 kHz
ADCP 300 kHz
Sippican XBT System (Mark 21)
Bathymetry System 3.5 kHz
ADCP 150 kHz
A-Frame
EM122 (12 kHz) Multibeam Echosounder

Shipboard Equipment Notes:
12 days of wamos data.   Need more information about how they process the WAMOS data and what they want for data.  Also, 24/7, or just on station?  rsl
 
All acoustics off for certain time periods, including ships doppler.  What can be on/off will vary depending on distance from the instrument.  rsl

EK 80.  Interested in observing,  but no data will be recorded.  rsl

Additional Information

Is night time work anticipated on this cruise?no
Specialized tech support (Seabeam, coring, other):
Other required equipment and special needs:

Mob/Demob Special Requirements: We will unload the container on the dock and will need a large forklift (> 5000 lbs capacity). We can operate the forklift if allowed, otherwise we will need an operator. Need ship crane support to load equipment on ship (max load 5000 lbs). We will plan to store the empty container on the dock if allowed, otherwise we would need to store on the ship for the experiment.
