Ecological surveys of the intertidal zone are proposed as being the most economical way in which the biologic impact of many wastes discharged into the estuarine and coastal marine environments can be assessed. Species diversity and community structure are the measures selected and these are determined through a carefully designed and statistically valid program of sampling. Aerial photography is used in developing the sampling program with infrared Ektachrome film providing information on the distribution and, to some extent, the nature of the intertidal flora. Dye tracers in the effluent are imaged on time sequence color aerial photographs and provide information on the patterns of waste dispersal. The methodology proposed is applicable only where well developed intertidal communities exist and only where either spatial or temporal controls can be established.
