September 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Inner Marsh transect

One hydrographic survey was performed on September 26, 2003, 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 low water tidal regime (flood tide). 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26日，研究团队沿达里安河（Darien River）、北河（North River）及阿尔塔马哈河（Altamaha River）北航道开展了一次水文调查，调查断面为内滩涂断面（Inner Marsh Transect, GCE-IM）。本次调查在低水位潮汐工况（涨潮）下，沿该断面的多个标称站位采集了垂直温盐深（CTD）剖面数据。调查期间测量了电导率、温度、压力及光学后向散射强度，并针对每条剖面计算得到水深、盐度与密度距平（sigma-t）。上浮阶段采集的数据已被剔除，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制。本数据集为佐治亚海岸生态系统长期生态研究（Georgia Coastal Ecosystems LTER）季度水文监测计划的组成部分。
