Periphyton Spatial Biomass distribution

Tiff Images of biomass spatial distribution of periphyton colonization at different times. The brigthness of each pixel represent the chlorophyl-a content estimated using the method described in: Saravia LA, Giorgi A, Momo FR (1999) A photographic method for estimating chlorophyll in periphyton on artificial substrata. Aquatic Ecology 33: 325–330. The initial letter of the file name correspond to the different tanks used in the experiment, then the number of the plate, and finally the date YYMMDD.
