Abstract

Aanderaa optodes are installed on various platforms (e.g. gliders, moorings, floats) to measure the oceanic dissolved oxygen. Here, an in situ calibration procedure for these optodes is presented to acquire field data with high accuracy. The procedure is little time consuming and includes a calibration against oxygen measurements from regular CTD casts (by attaching the optode to the CTD rosette) that are conducted immediately prior to and after the field experiment. In addition, onboard laboratory calibrations are performed to define extreme conditions of dissolved oxygen that are not captured with the CTD casts. The procedure is presented with a particular focus on glider observations.
