March 2002 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Four hydrographic surveys were performed from March 22 to March 23, 2002, 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 0km to 29km along the transect during various 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.

2002年3月22日至23日，研究团队沿狼岛以南阿尔塔马哈河与萨佩洛湾之间的沿岸水道（Intracoastal Waterway）开展了4次水文测量，该测线被命名为沿岸水道断面（Intracoastal Waterway Transect, GCE-IC）。在该测线0km至29km的区间内，于不同潮汐条件下以不同采样间隔采集了垂直温盐深仪（Conductivity Temperature Depth, CTD）剖面。本次测量获取了电导率、温度、压力、光学后向散射强度、光合有效辐射、溶解氧及叶绿素a荧光数据，并为每条剖面计算得到水深、盐度与sigma-t密度参数。上行剖面采集的所有数据值均已被剔除。本数据集作为佐治亚海岸生态系统长期生态研究（Georgia Coastal Ecosystems LTER, GCE）季度水文监测计划的组成部分完成采集。
