Taxonomic classification of the sediment microbiome observed under each of the storage conditions. Onsite subsampling and sequencing (black bars), frozen subsamples taken onsite and later (36 h?) sequenced in the laboratory (blue bars) and core stored for 10 weeks at 4 °C prior to subsampling and sequencing (green bars). Error bars indicate standard error, n = 10. Asterisks indicate significant (P =  < 0.05) results of pairwise comparisons using Tukey multiple comparison test; number of asterisks indicate level of statistical significance
