Data for "Centennial-scale Tropical Cyclone Frequency in the Western North Atlantic Modulated by Gulf Stream Position during the Little Ice Age"

The dataset presented accompanies the paper "Centennial-scale Tropical Cyclone Frequency in the Western North Atlantic Modulated by Gulf Stream Position during the Little Ice Age" (Forman et al.; submitted). The data correspond to the tropical cyclone (TC) reconstruction obtained via a log-linked calibration of stalagmite BER-SWI-13 Mg concentrations to HURDAT2 reanalysis data. For more information on the dataset and its generation please see the above publication and for additional detail on the BER-SWI-13 record see Forman et al. (2025; https://doi.org/10.1038/s43247-025-02446-3). More details are provided in the data file.
