Suspended matter and hydrographic properties of the New York Bight apex were studied three days after passage of Hurricane Belle (August 1976). Distributions of suspended matter were found to be similar to those present during previous periods of calm summer weather. By comparing the present poststorm observations with previous poststorm sampling, it is hypothesized that during summer a stratified water column can restrict vertical mixing of resuspended bottom material to the relatively thin near-bottom layer, whereas mixing throughout the water column takes place during unstratified winter conditions. Clearing times for resuspended material, therefore, are shorter in summer than in winter. Both extent of vertical mixing and clearing times are important considerations for those concerned with problems of marine ecology.
