Year 2003, 15 minute measurements of stage, water temperature, conductivity, dissolved oxygen, and pH on the Ipswich R. mainstem at North Reading, just upstream of Rt. 28 (~48 km2 drainage area).

Year 2003, continuous measurements, every 15 minutes, were made of stage, water temperature, conductivity, dissolved oxygen, and pH in a small headwater stream draining a moderate sized, mixed land use watershed. Measurements are for part of the ice free season (March – December). No Discharge was determined because beaver activity prevented rating curve estimate. Several day gaps occur periodically due to removal for recalibration.

2003年，研究人员对汇水于中等规模混合土地利用流域的小型源头溪流开展了每15分钟一次的连续监测，监测指标涵盖水位、水温、电导率、溶解氧及pH值。本次监测覆盖无冰期的部分时段（3月至12月）。由于海狸活动干扰，无法构建水位流量关系曲线以估算径流量，因此未测定径流数据。此外，因监测设备拆卸后需重新校准，监测序列周期性出现数日的数据间断。
