October 2001 CTD, PAR, oxygen and chlorophyll 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, 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.2001年10月11日至16日，研究团队沿达里安河、北河及阿尔塔马哈河北航道（内部潮滩样带，GCE-IM）开展了5次水文调查。在涨潮与落潮时段，沿该样带的多个标称测站采集了垂直温盐深（Conductivity Temperature Depth, CTD）剖面数据。本次测量涵盖电导率、温度、压力、光学后向散射系数（optical back scatter）、光合有效辐射（photosynthetically-available radiation）、溶解氧以及叶绿素a荧光，并为每条剖面计算得到水深、盐度与密度σ_t（sigma-t）。上行剖面采集的数据值均已被剔除。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。
