Adopting open-source technology to simulate daily saltwater intrusion on a tidal freshwater wetland
Conventional (manual) methods for soil amendment in a tidal wetland require time and energy-consuming actions such as a daytime application during weekly site visits at best. This manual approach increases the source and probability of experimental errors due to frequent and direct human involvement. To both overcome the disadvantages of manual work and accomplish a more natural transition of wetland salinization, we designed and installed a solar-powered irrigation system built from an open-source microcontroller and off-the-shelf electronics for simulating saltwater intrusion on a tidal freshwater wetland. Continuous operation of the system during the growing season has transitioned the soil salinity from freshwater to oligohaline and allowed us to observe the resulting biological changes in carbon cycling. We will describe the stages of development from designing the system, selecting the electronic and hardware components, integrating these components with the Arduino, programming the system, and installation in the field. This system could be easily adapted for other ecosystem manipulations to help enhance our understanding of environmental change.
