March 2003 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Intracoastal Waterway transect

Four hydrographic surveys were performed from March 26 to March 20, 2003, 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 -19km to 12km 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.2003年3月26日至3月20日，研究团队在狼岛以南的阿尔塔马哈河与萨佩洛湾之间的内陆水道（Intracoastal Waterway）沿线完成四次水文调查作业，对应断面编号为内陆水道断面（Intracoastal Waterway Transect, GCE-IC）。在不同潮汐工况下，沿该断面在-19km至12km的范围内以不等间隔采集了垂直温盐深仪（CTD, Conductivity, Temperature, Depth）剖面。本次调查同步测量了电导率、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，并针对每条剖面计算得到水深、盐度及sigma-t（密度距平）。上行剖面采集的原始数据均予以剔除。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。
