Three files containing data sets used in the paper titled "Prediction of Gas Hydrate Formation at Blake Ridge using Machine Learning and Probabilistic Reservoir Simulation" published in Geochemistry, Geophysics, Geosystems (G-Cubed). Two files are in ASCII format and contain geographic information and geophysical or statistical variable values. The third (FigureData.h5) is in HDF5 format and contains sediment profile outputs used to make each of the figures in the manuscript. Groups are named after the Figure they correspond to (i.e., Figure_03, Figure_04, Figure_06, and Figure_11). Description of the files is provided in "Data Description SAND2021-2004 O.pdf" along with example Python scripts on how to load data into arrays.
