Figure Q . Response of JFE AroW-USB (sn 0181) to changing dissolved oxygen concentrations at 5.3 oC and S=8.98. Top
Panel: Time series of instrument readings and Winkler reference samples drawn at level of sensor foil in well-mixed test
tanks. The decay in instrument signal under high DO exposure likely reflects bubble contamination of DO sensor foil.
Bottom Panel : Corresponding offset between instrument reading and Winkler DO reference sample during the trial.
Dotted line represents zero offset from reference.
