Abstract

A new dissolved oxygen sensor for marine application was developed and first tests in the field were carried out. The sensor uses a micro-electrode as the sensing element that has an inherently fast response and an increased resistance to biofouling due to the properties of the electrode material, platinum, and the employed operation repime.

Introduction of a cleaning cycle, where the potential applied to the electrode is altered, allows the elimination of material building up at the electrode surface as well as the reconditioning of the electrode surface, thus minimizing drift and the effect of bio-fouling.

Micmdisc electrodes ranging between 10 and SO pm diameter have been tested. The sensor has been adapted to operate on a CTD system or on towed instrument platforms. Results of test cruises will be presented,
