Photographing Frazil Particles in the Field

DSCN0468x

Underwater frazil on the Kananaskis River, AB (Canada) Feb. 19, 2013

Here’s a shot of the underwater camera system MSc grad student Vincent developed for measuring suspended frazil particle sizes.  In between the camera and the light, there are two polarizing filters – the camera takes photos of the frazil particles as they pass between these two filters.   To see an example of the type of photos this system takes – check out this earlier post.
