What do the instruments do?

Most measure the in-situ size and/or concentration of suspended particles – sediment grains, algae, flocs, oil droplets, air bubbles, aeolian sediment, drilling fluids etc. One model takes pretty particle pictures using holography. Others again measure water optical properties such as beam attenuation, Volume Scattering Function (VSF), and hyperspectral backscatter.
