December 2002 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Sapelo River transect

Three hydrographic surveys were performed on December 12, 2002, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at approximately 2km intervals from 0km to 36km during low and high tidal regimes. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.2002年12月12日，研究团队沿从佐治亚州萨佩洛湾（Sapelo Sound）溯萨佩洛河（Sapelo River）至尤洛尼亚（Eulonia）的断面开展了3次水文调查（萨佩洛河断面，GCE-SP）。在低潮与高潮潮汐时段，沿0km至36km的范围以约2km的间隔采集垂直温盐深（CTD）剖面数据。本次测量了电导率、温度、压强与光学后向散射信号，并针对每条剖面计算得到水深、盐度与sigma-t。剔除上升剖面采集的数据后，将剩余数据按0.5m深度层进行平均，并通过插值生成平滑剖面以用于等值线绘制。本数据集为佐治亚海岸生态系统长期生态研究（LTER）季度水文监测计划的组成部分。
