Sinking into the marsh (PLE day 3)
The Pymatuning wetlanders spent the morning learning more about wetland hydrology, and the afternoon installing wells and collecting data on plant communities at Pymatuning Marsh. They equipped the wells with pressure transducers, which log total pressure and temperature every 15 minutes. We will leave them in the marsh for the next week or so, and then examine the data to assess the causes of diurnal water-level fluctuations.
The students also established two transects along the water-depth gradient in the marsh and collected percent cover estimates for plant species, as well as measurements of water chemistry and and water depth. We will collect similar datasets from other sites over the next few days as part of a project comparing the vegetation of different wetland types. As the students were collecting data on plant communities they also began their plant collections.
For many of the students, this was their first experience walking through a deep marsh with an organic-rich substrate. As the video below shows, it took them some time to find their bog legs. Another fun day at PLE!
