GBWA Baseline Environmental Data 2010-2012

This data was taken from 2010-2012. It was taken with the YSI meter, the professional plus series, with the quatro sensors. This data is presented as a list of each data repatition entry taken at each site during each visit. The data is up loaded with excel 2010. Each excel data set, sheet 1 is "QAPP DATA" and sheet 2 "NON QAPP DATA". The "QAPP DATA" is what is listed in the Native Village of White Mountain's Quality Assurance Program Plan (QAPP). The "NON QAPP DATA" is other data collected by the YSI meter which is not listed in the NVWM's QAPP. You will notice the data for Dissolved Oxygen mg/L has dropped significantly in 2012 from previous years. We believe this data to be inaccurate because of sensor malfunction.

本数据集采集于2010年至2012年间，采用YSI专业增强型系列水质分析仪（YSI meter）及四通道传感器完成数据采集。本数据集以每次监测到访时各监测点位的重复采样条目列表形式呈现，已通过Excel 2010上传存储。每个Excel数据集包含两个工作表：工作表1为"QAPP DATA"，工作表2为"NON QAPP DATA"。其中"QAPP DATA"指符合怀特山原住民村落（Native Village of White Mountain，简称NVWM）质量保证项目计划（Quality Assurance Program Plan，简称QAPP）要求的数据条目；"NON QAPP DATA"则为YSI分析仪采集的、未纳入NVWM QAPP的其他数据。可观察到2012年的溶解氧（Dissolved Oxygen，单位：mg/L）数据较往年出现显著下降，我们推测该数据因传感器故障而不准确。
