SBE-63 Optical Dissolved OxygenSea-Bird ElectronicsDue to increasing science demands, Sea-Bird developed an individually calibrated, high-accuracy, optical oxygen sensor to assist in critical hypoxia and ocean stoichiometric oxygen chemistry research. With this new sensor, a myriad of moored and float-based platforms can contribute significantly in these driving areas of importance. The SBE 63 sets the oxygen measurement standard for oceanographic research. Careful choices of materials and geometry are combined with superior electronics and calibration methodology to yield significant gains in performance.Each SBE 63 is calibrated individually in a temperature-controlled bath. Bath temperatures are varied at each of 4 oxygen values, providing a comprehensive 24-point calibration. Two reference sensors in each bath are standardized against Winkler titrations. Response time tests are conducted on each sensor, using gas. Salinity and pressure impacts on sensor response are each checked at two separate points. The SBE 63 is designed for use in a CTD's pumped flow path, providing optimum correlation with CTD measurements. The elapsed time between the CTD and associated oxygen measurement is easily quantified, and corrected for in post-processing. The plumbing's black tubing blocks light, reducing in-situ algal growth. |
