October 2001 CTD, PAR, oxygen and chlorophyll 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, optical back scatter, photosynthetically-available radiation, oxygen and chlorophyll a fluorescence were measured, and depth, salinity and sigma-t were calculated for each profile. Data values collected during the upcast were deleted. 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，沿佐治亚州阿尔塔马哈河（Altamaha River）自东向西的溯河断面共开展8次水文调查（阿尔塔马哈河断面，GCE-AL）。在潮汐涨落工况下，沿该断面从分界点以东2km处（站位-02）至上游28km处，以1~2km的间隔采集了垂直温盐深（CTD）剖面数据。本次测量涵盖电导率、温度、压力、光学后向散射、光合有效辐射、溶解氧及叶绿素a荧光，并针对每条剖面计算了水深、盐度及sigma-t（密度距平）。上浮过程中采集的数据均已剔除。本数据集为佐治亚州海岸生态系统长期生态研究（Long-Term Ecological Research, LTER）季度水文监测计划的组成部分。
