Abstract. A new approach to autonomously determine concentrations of dissolved inorganic carbon (DIC) and its carbon stable isotope ratio (?13C–DIC) at high temporal resolution is presented.

The simple method requires no customised design. Instead it uses two commercially available instruments currently used in aquatic carbon research. Continue reading
