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

Three hydrographic surveys were performed on September 27, 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 0km 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9月27日，沿佐治亚州萨佩洛海峡至萨佩洛河直至尤洛尼亚的断面（萨佩洛河断面，GCE-SP）开展了3次水文调查。在落潮与涨潮潮汐工况下，于0km至36km的区间内以3-4km的间隔采集垂直温盐深（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、光合有效辐射、溶解氧以及叶绿素a荧光值，并针对每份剖面计算得到水深、盐度及sigma-t（密度距平）数值。上行剖面采集的原始数据已被全部剔除。本数据集作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一部分完成采集。
