Fraxinus nigra tree-ring dataset for dendrohydrology study in the Lake Duparquet, and reconstruction of the Harricana River spring discharge, Québec, Canada.

Dataset include earlywood vessels and tree-ring width chronologies derived from black ash (Fraxinus nigra Marsh.) trees growing in Lake Duparquet in eastern boreal Canada (Québec) reported in “Multi-century tree-ring anatomical evidence reveals increasing frequency and magnitude of spring discharge and floods in eastern boreal Canada” published in “Global and Planetary Change” by Nolin et al., 2021.

DUPARQUET_Chronologies.csv, as in Figure 2, the 12 anatomical and ring-width chronologies developed for Lake Duparquet to reconstruct Harricana River spring discharge ;

DUPARQUET_lat_lon.kml, the coordinate data for each station sampled on Lake Duparquet ;

HARRICANA_rec&cal.csv, as in Figure 3A, the instrumental and reconstructed Harricana River spring discharge for the two models REC1 and REC2 ;
