December 2003 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Doboy Sound transect

Three hydrographic surveys were performed from December 4 to December 5, 2003 , along an east-to-west transect through Doboy Sound near Sapelo Island, Georgia (Doboy Sound Transect, GCE-DB). Vertical CTD profiles were collected at approximately 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.

2003年12月4日至5日，研究团队沿佐治亚州萨佩洛岛附近多博伊湾（Doboy Sound）的东西向断面开展了三次水文调查，该调查记为多博伊湾断面调查（Doboy Sound Transect, GCE-DB）。在落潮与涨潮条件下，沿该断面从-2km至12km的区间内，以约2km的间隔采集了垂直CTD（Conductivity Temperature Depth，电导率-温度-深度仪）剖面数据。本次观测测定了电导率、温度、压力与光学后向散射系数，并针对每条剖面计算得到水深、盐度及σ_t（sigma-t，密度偏差参数）。上行剖面采集的观测数据均被剔除，剩余数据以0.5m深度分层取平均，经插值生成平滑剖面以供等值线绘制。本数据集系佐治亚海岸生态系统长期生态研究（Long Term Ecological Research, LTER, GCE）季度水文监测计划的组成部分。
