Reported are DNA and RNA concentrations from two different deployments, the means of DNA and RNA concentrations (as the average concentrations of nucleic acids from the two different deployments), standard deviations, standard errors, and the coefficient of variation of DNA and RNA concentrations. All data are relative to all sampling periods and to the top 0 to 5 mm of sediment.
