Abstract: We provide the dataset of climate variables related to the research article "Paleoclimate reconstruction of the Prince Creek Formation, Arctic Alaska, during Maastrichtian global warming" [1]. The dataset includes mean annual precipitation (MAP) values determined using two independent proxies, estimates of the oxygen isotope composition of meteoric water (δ <superscript>18</superscript> O <subscript>w</subscript> ) obtained from smectites and a comparison with previously published siderite data. We also provide the data used to calculate the total flux of CO <subscript>2</subscript> required for the weathering of silicates. This dataset is an example of a multi proxy approach that could add further insight for researchers in the selection of suitable proxies for paleoclimatic interpretations.<br /> (© 2020 The Author(s).)
