Multiproxy Reconstruction of Pliocene North Atlantic Sea Surface Temperatures and Implications for Rainfall in North Africa
<p>This dataset accompanies the publication by Wycech et al. "Multiproxy Reconstruction of Pliocene North Atlantic Sea Surface Temperatures and Implications for Rainfall in North Africa" in <em>Paleoceanography and Paleoclimatology</em>. The dataset is comprised of the raw paleo-proxy (Mg/Ca ratios and U<sup>k’</sup><sub>37</sub>) data and reconstructed sea surface temperatures (SSTs) from the early Pliocene (5 Ma) to modern. The provided data were input into the accompanying R codes, which executed principal component analysis and generated the results described in Wycech et al.</p>
