October 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Inner Marsh transect

Five hydrographic surveys were performed between October 11 and October 16, 2001, 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 during flood and ebb 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.2001年10月11日至10月16日，研究团队沿戴里恩河（Darien River）、北河（North River）及阿尔塔马哈河（Altamaha River）北航道开展了5次水文测量工作，对应断面为内湾沼泽断面（Inner Marsh Transect, GCE-IM）。测量在涨潮与落潮时段进行，沿该断面的多个标称站位采集了垂直温盐深（CTD）剖面数据；每条剖面均测定了电导率、温度、压力与光学后向散射参数，并计算得到水深、盐度及sigma-t值。上行航迹采集的原始数据予以剔除，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（Georgia Coastal Ecosystems）长期生态研究（Long-Term Ecological Research, LTER）季度水文监测计划的组成部分。
