description: This repository holds the data files associated with manuscript Grant et al., Regional amplified warming in the Southwest Pacific during the mid-Pliocene (3.3-3.0 Ma), submitted to Climate of the Past. https://doi.org/10.5194/egusphere-2023-108 The R Script and R Data used to analyse the data and produce the figures can be found in GitHub repository https://github.com/GRG-GNS/Pliocene-SST-Southwest-Pacific.git ###########Terms and units Sea Surface Temperatures (SSTs) are in degrees Celsius. Latitude are in degrees north. Longitude in degrees east. NZESM (New Zealand Earth system model; Williams et al., 2016), UKESM (United Kingdom Earth System model; Sellar et al., 2019), HadISST 1870-1879 AD (HadleyCentre Sea Ice and Sea Surface Temperature; NCAR, 2022), mPWP (mid-Pliocene Warm Period 3.3 - 3.0 Ma), MIS5e (Marine Isotope Stage 5e; 125 ka). SSP1 /2/ 3 (Socio-economic Pathways; IPCC). UK'37 - alkenone biomarker SST proxy TEX - TEX86 biomarker SST proxy Two periods were extracted from NZESM and UKESM i) 2036-2040 AD for SSP 2, and ii) 2090-2099 AD for SSP1, SSP 2, SSP 3. These are provided as stand alone values and in reference to HadiIST (e.g. NZESM - HadISST or NZESM.HadISST) <strong>Table 2.</strong> <strong>Statistical distribution of mid-Pliocene Warm Period (3.3-3.0 Ma) Sea Surface Temperatures anomalies (SST; °C) relative to HadiSST (1870-1879 AD) using </strong> <strong>BAYSPLINE calibration (Tierney and Tingley, 2018). The total range is calculated as the difference between maximum and minimum temperature and represents glacial to interglacial extremes. </strong> <strong>Table 3.
