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

One hydrographic survey was performed on December 11, 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 under a low water tidal regime (late ebb to early flood tide). 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12月11日，沿达里安河、北河及阿尔塔马哈河北航道的内沼泽样带（Inner Marsh Transect, GCE-IM）开展了一次水文调查。本次调查沿该样带的各名义测站，在枯水潮汐条件（落潮后期至涨潮初期）下采集了垂直温盐深仪（Conductivity Temperature Depth, CTD）剖面数据；测量获取了电导率、温度、压力、光学后向散射、光合有效辐射、溶解氧及叶绿素a荧光数据，并针对每条剖面计算得到水深、盐度及密度σ_t（sigma-t）。上浮剖面阶段采集的数据已被剔除。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。
