Mesocosm characteristics, rarefaction curves and multivariate analyses from Future climate change is predicted to affect the microbiome and condition of habitat-forming kelp

Details of mesocosm treatments (Table S1), rarefaction curves (Fig.S1) and multivariate tests of changes in microbial communities among temperature and/or pH treatments and/or condition (Tables S4,S6). Univariate tests for numbers of blisters and photosynthetic efficiency of kelp among treatments (Table S5).
