Fig. 1From: Microbial community profiles grown on 1020 carbon steel surfaces in seawater-isolated microcosmDiversity and abundance indices of the samples after 5, 30, 60, and 120 days in isolated microcosm. Panels a and b show the Shannon and Simpson diversity indices. c Abundance measurement index calculated by the Chao1 method. d Comparison between diversity indices of samples 5, 30, 60, and 120 daysBack to article page
