March 2004 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Doboy Sound transect

Two hydrographic surveys were performed on March 14, 2004, along an east-to-west transect through Doboy Sound near Sapelo Island, Georgia (Doboy Sound Transect, GCE-DB). Vertical CTD profiles were collected at 2km intervals from -2km to 12km along the transect during low tide and high tide conditions. Conductivity, temperature, pressure and optical backscatter were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected on the upcast were deleted, and the remaining data were averaged within 0.5m depth bins and interpolated to produce a smooth profile for contouring. This data set was collected as part of the Georgia Coastal Ecosystems LTER quarterly hydrographic monitoring program.

2004年3月14日，针对佐治亚州萨佩洛岛附近的多博伊水道断面（Doboy Sound Transect, GCE-DB）开展了两次水文调查。在落潮与涨潮条件下，沿该断面在-2km至12km的区间内，以2km为间隔采集了垂直温盐深（CTD）剖面数据。每段剖面均测量了电导率、温度、压力及光学后向散射参数，并计算得到水深、盐度与比密（sigma-t）。剔除上行剖面采集的数据后，对剩余数据按0.5米深度分层进行平均处理，并通过插值生成用于等值线绘制的平滑剖面。本数据集作为佐治亚沿岸生态系统长期生态研究（Long Term Ecological Research, LTER）季度水文监测项目的组成部分采集完成。
