Data on the changes in different Köppen-Geiger climate zones in response to changing CO2 forcing for the Valanginian, Turonian and Maastrichtian. The aquifer-eustasy response to these changes are also calculated along with the statistics on modern water table depths used in the calculations. We also capture the range of CO2 estimates for the Valanginian, Turonian and Maastrichtian.

Whole-rock geochemical data for the Late Cretaceous Kanguk Formation at the Sawtooth Range and Slidre Fiord localities, Ellesmere Island, Canada.

A petrographical study of 139 thin sections of samples representing the facies variations observed in the studied sedimentary successions. Skeletal and non-skeletal grains were classified, and the overall texture was identified following the Dunham classification (1962). A biostratigraphic analysis of ammonites and benthic and planktic foraminifera that have been extracted from 33 mudstone samples supported the sedimentary and stratigraphic analysis. These samples have been washed after treatment with diluted hydrogen peroxide and sieved into multiple fractions (from 0.2 to 1 mm). The extracted foraminifera were identified using a Leica EZ4 binocular microscope.
