1. Particles, VSF, Size Distribution John Trowbridge & Yogi Agrawal

2. what we measured... u Particle size distribution –from a profiler –from a tripod on bottom u Particle settling velocity distribution –from a tripod u VSF from 0.1 to 20 0.

3. Current focus u VSF and its variability u Is Junge real? –Over vertical profiles –Off tripod u Interesting data from 400 profiles follows –two movies show Optical Transmission, and VSF

4. Wind-speed for the movies..

5. optical transmission, vertical profiles (movie)

6. vertical profiles, VSF (movie)

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

9. Work in progress u Integration of particles data into Trowbridge’s model u Detailed examination of Junge form in water column u Bringing some order to the variability of VSF
