Install fiber optic cable to detect groundwater upwelling in small section of Newtown Creek Canal in New York City. The site has DNAPL contaminants.

At a New York study area 1.2 acres of sediment were monitored for evidence of groundwater seeps using a fiber optic distributed temperature sensor (DTS). A fiber optic cable was installed and monitored, providing 1.0 kilometers of cable laid out in six transects, each approximately 140 m in length and separated by 5-8 m. The DTS system recorded sediment temperatures at half-meter intervals every 20 minutes in September, 2019, yielding approximately 1.5 million temperature measurements during the study. Temperature data was analyzed through a suite of analytical methods to identify potential groundwater discharge locations.

在纽约研究区域1.2英亩的沉积物中，利用光纤分布式温度传感器（DTS）监测了地下水渗漏的证据。一根光纤电缆被安装并监测，沿六条测线铺设了1.0公里的电缆，每条测线长度约为140米，测线间相隔5-8米。2019年9月，DTS系统以20分钟为周期，每隔半小时记录一次沉积物温度，在研究期间共获得约150万次温度测量数据。通过一系列分析手段对温度数据进行处理，以识别潜在的地下水排放位置。相关数据可通过联系[e-mail]获取。
