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

Three hydrographic surveys were performed on December 12, 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12月12日，沿佐治亚州萨佩洛湾（Sapelo Sound）至欧洛尼亚（Eulonia）的萨佩洛河（Sapelo River）断面（萨佩洛河断面，GCE-SP）开展了3次水文调查。在低潮与高潮潮汐时段，于0km至36km的范围内以约2km的间隔采集垂直温盐深（CTD）剖面数据。本次测量涵盖电导率、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水深、盐度与sigma-t密度距平。上行剖面采集的所有数据值均已剔除。本数据集为佐治亚海岸生态系统长期生态研究（LTER）季度水文监测项目的组成部分。
