DESCRIPTION  (240) :
Version 3b of the UVP. Built for the study of MARINE SNOW and ZOOPLANKTON.
Coupled with SBE19 pumped CTD and Chelsea Fluorometer and Nephelometer.	

TECHNICAL CHARACTERISTICS (240) :
1000 m operational depth / 2 CCD B&W cameras (24 & 6 mm lenses) / In situ recordings at 25 Hz	
Marine snow mode with structured strobes lights : 0.6 & 9.3 litres analysed volume per image for		
90 & 240 µm ESD detection limits. (>90 & >460 µm available data set.)
Zooplankton mode with continuous 400 W spots : viewed surface :
425 x 325 mm at 500 mm from the lenses.
Time synchronisation with CTD.
