River ecosystem phenology in an increasingly ice-free world: Ecological monitoring sites on the Pemigewasset River
Ran across one of our sensors and want to learn more?
Water Quality Sensors
We put our sensors into protective plastic cases to prevent damage from ice, debris, and other rocks in the river. If you look closely, you can see the sensor through the holes in the logger case. You will also see a light monitor on the outside of the case. This logger lets us know when it is light or dark outside.
Here's what some data looks like:
GPP = gross primary productivity; IQR = interquartile range; DOY = day of year (for example, 1 = Jan 1)
Field Camera Imagery
Our field cameras are located at different locations along the river's edge. Daily photos help us identify how much water is in the stream, what portion of it is ice or snow covered, and most importantly, the timing and duration of ice cover on the river. All of these factors are not only important for the organisms in the stream but also for us. Frequent ice breakups and ice jams can often cause flooding in our neighborhoods.
If you think you found one of our sensors or field cameras or if you have any further questions, feel free to reach out to me at email@example.com.
