Annual summaries of daily observations from the USGS Streamflow Gauging Station on the Altamaha River near Doctortown, Georgia, for 1932 to 2004

Daily averaged river discharge data were obtained from the United States Geological Survey for streamflow gauging station USGS 02226000 on the Altamaha River near Doctortown, Georgia. Processed tabular data were downloaded from the USGS real-time web server (http://waterdata.usgs.gov/nwis/) by the Georgia Coastal Ecosystems LTER project, documented, and standardized to metric units. Missing values of mean discharge were estimated by cubic spline interpolation to fill in data gaps of five or fewer consecutive days. Annual summary statistics were then calculated from daily values aggregated by year.

本数据集的日平均河流流量数据源自美国地质调查局（United States Geological Survey, USGS），采集自佐治亚州多克敦附近奥塔姆哈河上的USGS 02226000号河道流量监测站。经处理的表格式数据由佐治亚海岸生态系统长期生态研究（Long Term Ecological Research, LTER）项目从USGS实时网络服务器（http://waterdata.usgs.gov/nwis/）下载，并完成了文档记录与公制单位标准化工作。针对连续5天及以内的流量数据空缺，采用三次样条插值法估算日平均流量的缺失值。随后基于按年份聚合的日度流量数据，计算得到年度汇总统计量。
