December 2002 CTD, PAR, oxygen and chlorophyll profiles for the Georgia Coastal Ecosystems Doboy Sound transect

Two hydrographic surveys were performed December 10, 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, 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.

2002年12月10日，针对佐治亚州萨佩洛岛附近的多博伊海峡开展了两次东西向断面水文调查，本次调查记为多博伊海峡断面调查（Doboy Sound Transect, GCE-DB）。在低潮与高潮潮汐条件下，沿该断面从-2公里至12公里的区间内，以约每2公里1个测点的间隔采集了温盐深（CTD）垂直剖面数据。本次测量获取了电导率、温度、压力、光学后向散射、光合有效辐射、溶解氧以及叶绿素a荧光数据，并针对每个剖面计算了水深、盐度与密度参数σ_t。剖面上浮阶段采集的数据已被剔除。本数据集为佐治亚海岸生态系统长期生态研究（LTER）季度水文监测计划的组成部分。
