October 2001 bin-averaged CTD profiles for the Georgia Coastal Ecosystems Sapelo River transect

Three hydrographic surveys were performed on October 13 and October 14, 2001, along a transect from Sapelo Sound up the Sapelo River to Eulonia, Georgia (Sapelo River Transect, GCE-SP). Vertical CTD profiles were collected at approximately 3km intervals from 0km to 36km during various tidal regimes. 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.

2001年10月13日至14日，研究团队沿佐治亚州萨佩洛湾（Sapelo Sound）至欧洛尼亚（Eulonia）的萨佩洛河（Sapelo River）断面开展了三次水文勘测，该断面被命名为萨佩洛河断面（Sapelo River Transect, GCE-SP）。在不同潮汐工况下，于0km至36km的区间内以约3公里的间隔采集垂直温盐深仪（CTD, Conductivity Temperature Depth）剖面数据。对各剖面测量了电导率、温度、压力与光学后向散射系数，并计算得到水深、盐度及密度距平（sigma-t, σ_t）。删除上行剖面采集的数据后，将剩余数据按0.5米的深度分层进行平均，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。
