Fraxinus nigra flood ring dataset for the study of flood history (1850-2017) of the Driftwood River, northwestern Ontario

Data include sample replication (N) and flood-ring frequencies (F1, F2) derived from black ash (Fraxinus nigra Marsh.) trees growing in the floodplain of the Driftwood River in northwestern Ontario reported in "Flood ring production modulated by river regulation in eastern boreal Canada" published in "Frontiers in Plant Science - Quantitative Wood Anatomy to Explore Tree Responses to Global Change" by Nolin et al. in 2021c.

DriftwoodFR.csv, as in Fig. 4, F1 and F2 flood-rings chronologies per sites and distance class with sample replication (N) to reproduce the flood-ring frequencies. Harricana River F1 and F2 flood ring chronologies from Nolin et al., 2021b are also provided.

DriftwoodRW.csv, as in Fig. 5, the mean site chronologies of total ring width with sample replication (N).

LAT_LON_Driftwood.kml, the coordinate data for each F. nigra stand sampled on the Driftwood River, including Monteith dam location, in Google Earth format (.kml)

meatadatas.txt, a set of self-explanatory instructions and descriptions for data files.

数据集包含来自西北安大略省Driftwood河流域的Fraxinus nigra Marsh.（黑桦树）生长地样本复制次数（N）和洪水环频率（F1，F2），这些数据由Nolin等人在2021年发表的《Frontiers in Plant Science - Quantitative Wood Anatomy to Explore Tree Responses to Global Change》（探索树木对全球变化的响应的定量木材解剖学）杂志上的《东部寒带加拿大河流调控对洪水环生产的影响》一文中报道。DriftwoodFR.csv文件，如图4所示，提供了各站点和距离等级的F1和F2洪水环年代序列，并包含了样本复制次数（N）以重现洪水环频率。此外，还提供了Harricana河流域的F1和F2洪水环年代序列，出自Nolin等人的2021b年研究。DriftwoodRW.csv文件，如图5所示，包含了各站点的总环宽平均年代序列，并包含了样本复制次数（N）。LAT_LON_Driftwood.kml文件，包含了在Driftwood河流域采样的每个F. nigra树群的坐标数据，包括Monteith大坝位置，并以Google Earth格式（.kml）存储。metadata.txt文件，包含了一组对数据文件进行自我解释的指令和描述。所有其他数据可根据要求由通讯作者[e-mail]（机构邮箱）或[e-mail]（永久邮箱）提供。
