N2 - This paper describes results using a nonabsorbing wavelength as an internal reference to correct for nonanalyte-related signal changes and long-term drift in an absorbance-based fiber optic sensor. A renewable-reagent sensor developed for seawater pCO2 (CO2 partial pressure) was repetitively calibrated over a 12-day period and the drift in the calibration was studied. The results indicate that although the internal reference significantly improves the long-term performance, it does not fully correct for all sources of drift over the 12-day period.
