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

Two hydrographic surveys were performed on September 24 and September 25, 2003, along an south-to-north transect up the Duplin River on Sapelo Island, Georgia (Duplin River Transect, GCE-DP). Vertical CTD profiles were collected at various nominal stations along the transect during various tidal conditions. 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.

本数据集采集自2003年9月24日与25日开展的两次水文调查，调查沿佐治亚州萨佩洛岛达普林河的南北向断面进行，该断面记为达普林河断面（Duplin River Transect, GCE-DP）。调查期间，在该断面的多个标称测站、不同潮汐条件下采集了温盐深（CTD）垂直剖面数据。本次调查同步测定了电导率、温度、压力、光学后向散射、光合有效辐射、溶解氧及叶绿素a荧光等参数，并针对每条剖面计算得到水深、盐度与西格玛-t（sigma-t）密度参数。其中，上行剖面采集的原始数据已被剔除。本数据集为佐治亚海岸生态系统长期生态研究（LTER）季度水文监测计划的组成部分。
