Mobile Water Quality Laboratory - Sonde (Mar 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.

新墨西哥州一处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）的研究课题。本研究通过高时间分辨率的连续化学监测，对河流水质的变化进行观测。本研究的核心研究对象为溶解态有机质（dissolved organic matter, DOM），研究中通过有机碳测量值对其进行近似表征。（现场每8至15分钟开展一次有机碳与无机碳浓度的监测工作。）本研究使用EXO sonde（YSI公司，美国俄亥俄州黄泉市45387）监测基础理化参数，以补充碳数据相关信息。采样工作选取位于隐藏谷附近的耶梅兹河东支一处布设了监测仪器的河曲段开展，该区域同时开展多项生态学与水文学研究。
