September 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Duplin River transect

Two hydrographic surveys were performed on September 24 and September 25, 2003, along an south-to-north transect up the Duplin River on Sapelo Island, Georgia (Duplin River Transect, GCE-DP). Vertical CTD profiles were collected at various nominal stations along the transect during various tidal conditions. 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.2003年9月24日与25日，研究团队沿美国佐治亚州萨佩洛岛达普林河的南北向断面（达普林河断面，GCE-DP）开展了两次水文调查。调查期间，在该断面沿线的多个标称站位、不同潮汐条件下，采集了垂直温盐深（CTD）剖面数据。本次测量涵盖电导率、温度、压力与光学后向散射系数，并针对每份剖面计算得到水深、盐度及密度Sigma-t值。上浮阶段采集的原始数据已被剔除，剩余数据按0.5米深度分层取平均，并通过插值生成平滑剖面以用于等值线绘图。本数据集为佐治亚海岸生态系统长期生态研究（LTER）季度水文监测项目的组成部分。
