Old Woman Creek State Nature Preserve and National Estuarine Research Reserve is one of the few remaining relatively natural freshwater estuaries in the Great Lakes region. On the south-central shore of Lake Erie, Old Woman Creek and lake water mix to form a unique ecosystem.
The 571-acre preserve provides critical habitat for native species and migrating birds and offers a unique opportunity to research the ecological benefits provided by these fragile estuarine systems.
To assist in the understanding and preservation of the estuary, an automated water monitoring system was installed at Old Woman Creek Nature Preserve. The system is part of a long-term data set collected at National Estuarine Research Reserves around the country.
Two water quality monitoring stations were deployed: one where Old Woman Creek enters the preserve and another near the mouth of the estuary. At both stations, NexSens Technology 4100-iSIC data loggers with radio telemetry and YSI 6600 multi-parameter sondes with temperature, conductivity, salinity, dissolved oxygen, pH, depth, and turbidity sensors were installed.
At each site, water quality and hydrology data is collected by the data loggers, which then transmit the information via license-free, spread spectrum radio to a 4100-BASE receiver located at the Old Woman Creek visitor center. A base station computer connects to the radio receiver, and uploads data to NexSens’ WQData web datacenter. This data is used in environmental education as well as restoration and resource management decisions.
Specifically designed for remote environmental monitoring applications, the iSIC data logger offers superior data acquisition performance in extreme conditions.
The YSI 6600 V2-2 sonde offers the most comprehensive water quality monitoring package available and is designed for use with the 6562 Rapid Pulse polarographic DO probe.
iChart software simplifies and automates many of the tasks associated with acquiring, processing, analyzing and publishing environmental data.
