September 2002 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Sapelo River transect

Three hydrographic surveys were performed on September 17, 2002, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at approximately 2km 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.

2002年9月17日，针对佐治亚州萨佩洛海峡沿萨佩洛河上溯至尤洛尼亚的断面（萨佩洛河断面，GCE-SP）开展了3次水文调查。在低潮与高潮潮汐状态下，于0km至36km的区间内以约2km的间隔采集垂直温盐深（Conductivity Temperature Depth, CTD）剖面数据。本次调查测量了电导率、温度、压力、光学后向散射系数、光合有效辐射、溶解氧以及叶绿素a荧光，并针对每条剖面计算了水深、盐度与西格玛-t（sigma-t）密度。本数据集删除了仪器上升程采集的全部数据，其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。
