Mobile Water Quality Laboratory - Sonde (Aug 2013)

The response of a high-altitude, New Mexico watershed to seasonal events is the subject of investigation at the New Mexico Tech Mobile Water Quality Laboratory. The study is founded on observing changes in the quality of stream water via continuous (high temporal resolution) chemical measurements. The major focus of the study is dissolved organic matter (DOM) which is approximated with organic carbon measurements. (Organic and inorganic carbon concentrations are measured every measured every 8 to 15 minutes on site.) An EXO sonde (YSI Inc., Yellow Springs, OH 45387) is measuring basic physicochemical characteristics to supplement the carbon data. Samples are collected from the East Fork of the Jemez River near Hidden Valley at an instrumented meander where several ecological and hydrological studies are concurrently taking place.新墨西哥州某高海拔流域对季节性事件的响应，是新墨西哥理工学院移动水质实验室（New Mexico Tech Mobile Water Quality Laboratory）的研究主题。本研究基于连续（高时间分辨率）化学测量手段，观测河流水质的变化情况。本研究的核心关注对象为溶解性有机质（dissolved organic matter, DOM），其浓度通过有机碳测量值进行估算。（现场每8至15分钟测量一次有机碳与无机碳浓度。）一台EXO多参数水质探头（EXO sonde，YSI Inc.，俄亥俄州耶洛斯普林斯市，邮编45387）正在监测基础物理化学特征参数，以补充碳数据相关的监测内容。采样工作在杰梅兹河（Jemez River）东支流靠近隐谷（Hidden Valley）的一处布设了监测仪器的河曲区域开展，该区域目前正同步开展多项生态学与水文学研究。
