March 2004 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Two hydrographic surveys were performed from March 13 to March 14, 2004, along the Intracoastal Waterway between the Altamaha River south of Wolf Island and Sapelo Sound (Intracoastal Waterway Transect, GCE-IC). Vertical CTD profiles were collected at various intervals from -15km to 32km 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.

本数据集于2004年3月13日至14日期间，在沃尔夫岛以南阿尔塔马哈河与萨佩洛湾之间的沿岸内陆航道（Intracoastal Waterway, IC）开展了两次水文调查，对应调查断面记为GCE-IC沿岸内陆航道断面（Intracoastal Waterway Transect, GCE-IC）。调查期间在涨潮与落潮两种潮汐工况下，沿该断面从-15km至32km的区间内以不同间隔采集了垂直温盐深（CTD）剖面数据，测量参数涵盖电导率、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，并针对每条剖面计算得到水深、盐度及密度距平（sigma-t）。其中，仪器上浮过程中采集的数据均已剔除。本数据集为佐治亚海岸生态系统长期生态研究网络（Georgia Coastal Ecosystems LTER）季度水文监测计划的一部分。
