Temperature, relative [K] (T rel) * PI: van der Bilt, Willem G M (https://orcid.org/0000-0003-3157-451X, willemvanderbilt@gmail.com) * METHOD: Calculated from UK37 (D'Andrea et al., 2016) (URI: https://doi.org/10.1016/j.gca.2015.10.031) * COMMENT: Calculated using the Group I calibration slope presented by D'Andrea et al. (2016). As we could not calibrate UK37 values to in-situ temperature observations for this study (no overlap with instrumental period) - we present the relative values generating by this algorithm.
