Particles, VSF, Size Distribution

Particles, VSF, Size Distribution

• John Trowbridge Yogi Agrawal

2
what we measured...

• Particle size distribution
• from a profiler
• from a tripod on bottom
• Particle settling velocity distribution
• from a tripod
• VSF from 0.1 to 200.

3
Current focus

• VSF and its variability
• Is Junge real?
• Over vertical profiles
• Off tripod
• Interesting data from 400 profiles follows
• two movies show Optical Transmission, and VSF

Number density through a vertical profile
A thorough examination of the validity of the
Junge model is in progress, with a look to
optical consequences.
8
Data needed

• Principally, data on upwelling dates..
• VSF data from other instruments for
  intercomparison

9
Work in progress

• Integration of particles data into Trowbridges
  model
• Detailed examination of Junge form in water
  column
• Bringing some order to the variability of VSF
