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
