Corrigendum to “Estimating absolute salinity (SA) in the world's oceans using density and composition” (Deep Sea Research Part I: Oceanographic Research Papers (2014) 93 (14–20), (S0967063714001381) (10.1016/j.dsr.2014.07.009))

Abstract

The authors of Woosley et al. (2014) regret an ambiguously worded sentence in the methods which may cause confusion concerning the calibration procedure. The sentence in the first paragraph of the methods on page 15 states:  “The system was calibrated using water and standard seawater.” The sentence implies that the densitometer was calibrated using standard seawater intended for calibration of salinometers. Instead the sentence should read: “The salinometer was calibrated with P-series standard seawater (OSIL, United Kingdom) and the densitometer was calibrated with ultra-pure Milli-Q water.” The error does not have any impact on the data, results, or conclusions but may impact the ability of others to reproduce the results. It is not currently recommended to calibrate densitometers with standard seawater because the long-term stability is not well known. Dissolution of the borosilicate glass bottle used to store the standard has been shown to occur over time causing an increase in the density without altering the conductivity. Density measurements of standard seawater were made (Table 1), but were not used in the calibration procedure. We apologize for any inconvenience caused.
