Figure F5. Examples of calibration data and fit residuals from the two kinds of autonomous temperature loggers deployed in CORK observatories during Expedition 301. In each case, symbols for factory calibration indicate temperatures indicated by the tools. We crossplotted tool and bath temperatures and fit second- and third-order polynomials to the data, yielding the residual misfits shown. Fitting with polynomials significantly improves tool accuracy and helps to eliminate systematic misfit. A. Calibration results from Onset tool 598. B. Calibration results from Antares tool 003.
