March 2002 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Doboy River transect

Two hydrographic surveys were performed on March 24, 2002, 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.

2002年3月24日，研究团队沿佐治亚州萨佩洛岛附近的多博伊海峡东西向断面（Doboy Sound Transect, GCE-DB）开展了两次水文调查。本次调查分别在低潮与高潮时段进行，沿该断面从-2km至12km的范围内，以约2km的间隔采集垂直温盐深（CTD, Conductivity Temperature Depth）剖面数据。测量内容涵盖电导率、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、盐度及密度距平（sigma-t）。上浮阶段采集的数据予以剔除，剩余数据按0.5米深度分层进行平均，并通过插值生成平滑剖面以用于等值线绘制。本数据集作为佐治亚州沿海生态系统长期生态研究（Long-Term Ecological Research, LTER）季度水文监测项目的一部分采集所得。
