September 2002 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Inner Marsh transect

One hydrographic survey was performed on September 18, 2002, 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 a high tidal regime. Conductivity, temperature, pressure, optical back scatter, photosynthetically-available radiation, oxygen and chlorophyll a fluorescence were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected during the upcast were deleted. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.

2002年9月18日，研究团队沿达里安河（Darien River）、北河（North River）以及阿尔塔马哈河（Altamaha River）北航道开展水文测量，对应样带为内部潮滩样带（Inner Marsh Transect, GCE-IM）。本次测量在大潮时段于该样带的多个标称测站采集了垂直温盐深（CTD）剖面数据，测量项目涵盖电导率、温度、压力、光学后向散射、光合有效辐射、溶解氧以及叶绿素a荧光，并针对每条剖面计算得到水深、盐度与标准密度sigma-t。仪器上行测量过程中采集的所有数据值均已剔除。本数据集作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一部分采集所得。
