Technical Note: The determination of enclosed water volume in large flexible-wall mesocosms "KOSMOS"

J. Czerny, K. G. Schulz, S. A. Krug, A. Ludwig, and U. Riebesell

Abstract. The volume of water enclosed inside flexible-wall mesocosm bags is hard to estimate using geometrical calculations and can be strongly variable among bags of the same dimensions. Here we present a method for precise water volume determination in mesocosms using salinity as a tracer. Knowledge of the precise volume of water enclosed allows establishment of exactly planned treatment concentrations and calculation of elemental budgets.
