May 2004 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Inner Marsh transect

One hydrographic survey was performed on May 28, 2004, along the Darien River, North River, and north channel of the Altamaha River (Inner Marsh Transect, GCE-IM). Vertical CTD profiles were collected at various nominal stations along the transect under a flood tidal regime. 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.本水文数据集的野外调查工作于2004年5月28日沿戴里恩河（Darien River）、北河（North River）以及奥塔姆哈河（Altamaha River）北航道开展，对应样带为内陆沼泽样带（Inner Marsh Transect, GCE-IM）。本次调查在涨潮工况下，沿该样带的多个名义测站采集了垂直温盐深（CTD）剖面数据。实测获取了电导率、温度、压力与光学后向散射系数，并针对每条剖面计算得到水深、盐度及西格马-t（sigma-t）密度值。上行测量所得数据已被剔除，剩余数据按0.5米深度分层求取平均值，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（Long Term Ecological Research, LTER）季度水文监测计划的组成部分。
