Located near Ball State University in Muncie, Ind., Cooper Farm is a diverse land area comprised of two properties: the Cooper Woodland Area and Cooper Natural Area. Within the farm, distinct micro-environments reflect various natural habitats found in east-central Indiana. The Cooper Farm offers students at Ball State an excellent outdoor laboratory for hands-on environmental education.
A major effort is underway to more actively restore natural communities in some areas of this 88-acre farm, including wetlands, prairie, and forest. Conversely, other areas will be left to develop without active restoration, to provide opportunities for studying the succession process. Researchers hope to establish baseline environmental data at various locations within the farm so they can better understand these processes.
NexSens Technology was contacted to assist in designing and implementing permanent monitoring stations for the biotic and abiotic components of the Cooper Field Area ecosystems.
Ball State University researchers selected radio telemetry as the most effective telemetry option for their monitoring network. Each of the five field site locations transmit data via license-free spread-spectrum radio to a NexSens 4100-BASE radio base station, which is connected to a PC at a nearby farmhouse.
Project members selected an optimal location on the farm to simultaneously monitor multiple weather and soil parameters. Atop a two-inch deployment pole, a Vaisala WXT510 multi-parameter weather sensor simultaneously monitors wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity.
Buried within the ground, Stevens Hydra Probe II sensors simultaneously monitor soil moisture, salinity, and temperature by measuring the electrical response of the soil. Researchers also set up a water evaporation monitoring system consisting of an evaporation pan and OTT Thalimedes shaft encoder. NexSens iChart software automatically calculates water evaporation based on changes in the water level.
At four stream and wetland sites throughout the farm, YSI 6920 V2-1 multi-parameter water quality sondes collect water quality data. Each sonde simultaneously measures temperature, conductivity, dissolved oxygen, pH, ORP, and turbidity data at user-specified intervals. NexSens 4100-iSIC data loggers collect the instruments’ water quality data, sending it at hourly intervals to the base station.
NexSens iChart software posts real-time environmental data to the web using a NexSens WQData web datacenter, providing open access to students and researchers. The water quality and weather monitoring sites, along with this easily accessible online data, will enhance opportunities for both education and research by students and faculty at Ball State University.
Specifically designed for remote environmental monitoring applications, the iSIC data logger offers superior data acquisition performance in extreme conditions.
The YSI 6920 V2-1 sonde is an economical logging system, ideal for spot sampling or short-term monitoring and profiling of temperature, conductivity, pH, ORP, dissolved oxygen, and turbidity.
The Vaisala WXT520 multi-parameter weather sensor is a compact and lightweight multi-sensor instrument that measures the most essential weather parameters.
iChart software simplifies and automates many of the tasks associated with acquiring, processing, analyzing and publishing environmental data.
