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，针对美国佐治亚州萨佩洛岛邻近的多博伊湾（Doboy Sound）东西向断面开展两次水文调查，该断面记为多博伊湾断面（Doboy Sound Transect, GCE-DB）。在低潮与高潮工况下，沿该断面从-2km至12km的区间内，以2km为间隔采集垂直温盐深（CTD，Conductivity Temperature Depth）剖面数据。本次调查实测电导率、温度、压力与光学后向散射参数，并针对每条剖面计算得到水深、盐度及密度距平σ_t（sigma-t）。弃除上行段采集的数据后，将剩余数据按0.5m深度分层取平均，并通过插值生成平滑剖面以用于等值线绘制。本数据集为佐治亚沿岸生态系统长期生态研究（LTER，Long Term Ecological Research）季度水文监测计划的组成部分。
