SPECTRAL BACKSCATTERING COEFFICIENT AND SUSPENDED PARTICLE SIZE DISTRIBUTION
 
Optical backscattering coefficient is a fundamental parameter in studies of remote sensing and suspended particulate material. Changes in suspended particle concentration, composition (shape and/or refractive index), and size distribution all affect optical backscatter. In order to investigate the evolution of spectral backscatter and explore its correlation with the in situ particle size distribution over the course of a spring phytoplankton bloom, weekly vertical profiles of a Hydroscat-6 (HOBI Labs) and an in situ floc camera were made in Bedford Basin, Nova Scotia. Hydroscat-6 is a multiwavelength, in-water, backscattering sensor that makes simultaneous backscatter measurements of six wavelengths in the visible range. Changes in spectral content of optical backscatter associated with changes in the particle size distribution due to flocculation of the bloom are investigated.
