Abstract: Phytoplankton pigment distributions during the spring isothermal periods of 1998 and 1999 and their association with episodic sediment resuspension were characterized in coastal waters of southern Lake Michigan. Total and phylogenetic group chl a concentrations (derived using chemical taxonomy matrix factorization of diagnostic carotenoids) corresponded with assembledge and group biovolumes estimated from microscopic enumeration (P 0.05), indicating uniform distributions of and photophysiological states for assemblages and diatoms and cryptophytes, respectively, throughout the mixed water column. Total chl a concentrations were not always spatially uniform from nearshore from near-shore to offshore waters, with the greatest variability reflecting the influence of tributary inflows upon coastal assembalges Sediment resuspension strongly influenced water column particle density and light climate; however, total and group chl a concentrations did not correspond with coefficients of Kd and suspended particulate matter concentration (P> 0.05). The correspondence of both light attenuation and suspended particulate matter concentration with relative diatom chl a (P
