There were two production errors in Fietzek et al. (2014) that require correction. First, in section 5 (p. 191) the cited reference at the end of last sentence of the first paragraph in the left column was incorrectly included. In fact, there is no such reference. The correct sentence should read: “Throughout the expeditions and beside the deployment in the flowthrough box, the sensors were additionally used for measurements on a CTD rosette system (HC1 and HC3; part of the data shown in Fiedler et al. 2013) and on a surface drifter (HC3; data not shown here).”
Specifications of the developed pCO2 sensor as used during the deployments discussed in this paper. The specifications of the currently available sensor model differ from these values with respect to size and power consumption. The power required for the temperature stabilization as well as the warm-up duration depend on the actual water temperature, the chosen control temperature as well as on the thickness of the insulation material. The given warm-up times correspond to a 24-V supply voltage in 20°C water and to 12-V supply voltage in 3°C water. Please refer to the text for further details regarding the warm-up and the zeroing interval. The response times refer to the usage of two different pump models at 20°C water temperature. The pump SBE 5T has a flow rate of approx. 105 mL s−1, while the smaller model, SBE 5M, provides a flow rate of approx. 35 mL s−1.
The staff of the Journal of Atmospheric and Oceanic Technology regrets any inconvenience these errors may have caused.
