March 2003 surface water bacterial productivity at ten Georgia Coastal Ecosystems LTER sampling sites

Surface water samples were collected during low tide survays near ten Georgia Coastal Ecosystem LTER sampling sites in March, 2003. The incorporation of tritiated leucine in unfiltered samples during one hour incubations was measured using a standard microcentrifuge method to estimate bacterial productivity in each sample. This study was part of the GCE-LTER hydrographic monitoring program, and will be repeated quarterly.

2003年3月，在佐治亚海岸生态系统长期生态研究（Long Term Ecological Research, LTER）的10个采样点附近开展低潮期调查，期间采集了地表水样本。采用标准微量离心法，对未过滤样本在1小时孵育过程中氚标记亮氨酸（tritiated leucine）的掺入量进行测定，以此估算各样本的细菌生产力。本研究属于GCE-LTER水文监测计划的组成部分，且将按季度重复开展。
