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12月5日，研究团队沿美国佐治亚州萨佩洛岛附近多博伊湾的东西向断面（多博伊湾断面，Doboy Sound Transect, GCE-DB）开展了3次水文调查。在落潮与涨潮条件下，沿该断面从-2km至12km的区间内，以约2km的间隔采集垂直温盐深剖面（CTD，Conductivity-Temperature-Depth）数据。本次调查测量了电导率、温度、压力及光学后向散射系数，并针对每条剖面计算得到水深、盐度与密度西格马（sigma-t）。将上行采集的数据予以剔除后，对剩余数据按0.5m深度分层求取平均值，随后通过插值处理生成平滑剖面以用于等值线绘制。本数据集为佐治亚海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一部分。
