June 2003 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Sapelo River transect

Three hydrographic surveys were performed on June 20, 2003, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at 3-4km intervals from -12km to 36km during low and high 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6月20日，研究团队沿佐治亚州萨佩洛海峡（Sapelo Sound）至萨佩洛河（Sapelo River）直至欧洛尼亚（Eulonia）的断面（萨佩洛河断面，GCE-SP）开展了3次水文调查。在高低潮时段，于-12km至36km的区间内以3~4km的间隔采集垂直CTD剖面数据。本次调查测量了电导率、温度、压力、光学后向散射强度、光合有效辐射、溶解氧以及叶绿素a荧光强度，并针对每条剖面计算了水深、盐度与密度层结参数σ-t。上行剖面采集的数据值均已剔除。本数据集为佐治亚沿岸生态系统长期生态研究（LTER）季度水文监测计划的组成部分。
