The first character in the sample name designates the environment type (S, marine sediment; W, water; and I, ice). The second character indicates the geographic location (R, Arctic; N, Antarctic; T, temperate; and P, tropical). The third character indicates whether the sequences were derived from cultured isolates (C) or environmental clones (U).
