Article describes tidal marsh morphology and characteristics by analysis of multispectral 

 photos. The photos were taken by a nine-lens multispectral camera and a panchromatic, 

 color, and color infrared photo corresponding to each set of nine-lens camera photos. Each 

 photo covered a narrow range of the spectrum between 400 and 900 miUimicrons. Study 

 area covered a tidal marsh in southwest San Francisco Bay. Investigation included drainage 

 features, water penetration, location of the land-water boundary, and vegetation types. The 

 nine-lens camera photos gave excessive duplication. A four-photo combination of color, 

 color infrared, black and white infrared, and a photo within the 550-630 millimicron 

 wavelength range was concluded to be the best system. Color photos were best for general 

 interpretation. A microdensitometer was concluded to be a useful interpretation tool.

Paper discusses applications of color and color infrared photos in studies of marshlands and 

 estuaries of the Patuxent River estuary in Maryland. The color and color infrared photos 

 were used for plant species identification and indications of water quality, turbidity, 

 pollution, and salinity. Salinity was determined from plant species associations. Color 

 infrared photos were superior to color photos in many respects. A summary of features and 

 interpretation keys for color infrared photos of marshlands and estuaries is presented.

Paper describes an investigation of nearshore biological resources in Biscay ne Bay, Florida, 

 from color photos. Various species of biota in the bay were mapped from color photos and 

 results compared to field data obtained by diving, sample collection and identification, 

 underwater photography, and sediment type and depth observations. Many features, 

 distributions, and relationships between vegetation and bottom conditions identified on the 

 photos would be difficult or impossible to recognize in the field. Photos showed good 

 correlation between bottom material (soft sediment or hard rock) and vegetative cover, 

 permitting the bottom to be mapped by interpretation of vegetation characteristics. Use of
