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

Three hydrographic surveys were performed on March 23, 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 various 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3月23日，研究团队沿佐治亚州萨佩洛海峡至萨佩洛河上游尤洛尼亚的断面（萨佩洛河断面，GCE-SP）开展了三次水文调查。在不同潮汐工况下，于0km至36km的区间内以约2km的间隔采集垂直温盐深（CTD，Conductivity Temperature Depth）剖面数据。本次测量涵盖电导率、温度、压力与光学后向散射参数，并针对每条剖面计算得到水深、盐度及比容密度（sigma-t）。上浮航段采集的数据已被剔除，剩余数据以0.5m深度分层进行平均，并通过插值生成可用于等值线绘制的平滑剖面。本数据集作为佐治亚沿岸生态系统长期生态研究（Georgia Coastal Ecosystems LTER）季度水文监测项目的一部分采集完成。
