A custom-built flume (mesocosm) facility was used to manipulate CO2 and temperature in order to test the impacts of seawater acidification and warming on microbial taxonomic marker and nitrogen cycling-gene abundances in both muddy and sandy coastal sediments. Experimental treatment levels contained representatives of present day CO2 and temperature levels and of those expected by 2100 under a 'business-as-usual' scenario (IPCC, 2007), with an emphasis on the interactive effects of reduced pH and increased sea water temperature on benthic microorganisms.
