Tree ages and Locations on the Eastern Shore of Virginia National Wildlife Refuge

Cores were taken from live trees in the hillslope site in the Eastern Shore of Virginia National Wildlife Refuge. "TreeAges.csv" has the ID of the tree, the UTM 18N Easting and Northing and the NAVD88 Elevation (these are identical to the hillslope "ALIVE" points in the topographic surveys - dataset VCR19288), and the year that the tree was established from the dendrochronology analysis. Complete methods for the dendrochronology analysis can be found in Fernandes et al. (2018) Declining radial growth response of coastal forests to hurricanes and nor'easters. JGR: Biogeosciences. (https://doi.org/10.1002/2017JG004125) Location and elevation data were collected using a real-time kinematic (RTK) Global Positioning System (GPS) unit.

研究所用树芯样本采自弗吉尼亚州国家野生动物保护区东岸山坡样地的活立木。TreeAges.csv 文件包含树木编号、通用横轴墨卡托投影（Universal Transverse Mercator, UTM）18N带东坐标、北坐标以及北美垂直基准面1988（North American Vertical Datum 1988, NAVD88）高程（该数据与地形测量中标记为"ALIVE"的山坡样点——数据集VCR19288——完全一致），以及通过树木年代学（dendrochronology）分析得到的树木定植年份。树木年代学分析的完整方法可参见Fernandes等人（2018年）发表于《JGR：生物地球科学》的论文《沿海森林径向生长对飓风及东北风暴的响应衰减》（https://doi.org/10.1002/2017JG004125）。位置与高程数据通过实时动态定位（real-time kinematic, RTK）全球定位系统（Global Positioning System, GPS）设备采集。
