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

Eight hydrographic surveys were performed from May 30 through June 4, 2001, along an east-to-west transect up the Altamaha River in Georgia (Altamaha River Transect, GCE-AL). Vertical CTD profiles were collected at 1-2km intervals from 2km east of the line of demarcation (station -02) to 28km upriver along the transect during flood and ebb 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5月30日至6月4日期间，佐治亚州阿尔塔马哈河沿东西向逆流断面（阿尔塔马哈河断面，GCE-AL）开展了8次水文测量作业。在涨潮与落潮周期内，沿该断面从分界点（站位-02）以东2km处至上游28km处，以1-2km的间隔采集了垂直温盐深仪（CTD）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、盐度与密度西格玛-t（sigma-t）值。上行测程采集的数据予以剔除，剩余数据按0.5m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网络（LTER）季度水文监测项目的组成部分。
