Overview
The Stevens Hydraprobe measures 21 different soil parameters simultaneously. The HydraProbe instantly calculates soil moisture, electrical conductivity, salinity, and temperature and supplies raw voltages and complex permittivity for research applications. A compact, rugged design with potted internal components makes the HydraProbe easy to deploy and leave in the soil for years without maintenance.
Electrical Response Parameters
The Stevens HydraProbe design is unique compared to other soil moisture probes because the electrical response of soils can be specified by two parameters - the dielectric constant and the conductivity. The dielectric constant is most indicative of water content, while the conductivity is strongly dependent on soil salinity. Unlike other capacitance-type sensors, the HydraProbe measures both of these components simultaneously. The high-frequency electrical measurements indicating the capacitive and conductive properties of soil are then directly related to the soil's moisture and salinity content, while a thermistor determines soil temperature.
Remote Capabilities
The HydraProbe soil moisture sensor includes SDI-12 or RS-485 outputs for interfacing with external data loggers such as the NexSens X3. Sensor cables can be factory-connected with NexSens UW plug connectors for integration to an X3 data logger sensor port. Data retrieval options using the X3 include direct-connect, Wi-Fi, cellular, and Iridium satellite telemetry.

Water Conservation and Smart Growth in Texas
As states face annual droughts and water use continues to grow in order to meet population and production demands, water conservation is essential to protecting natural resources and long-term reliance. Over the years, conserving water has become more necessary as the world’s natural resources continue to be strained in order to meet needs. As a result, water conservation consultants have filled an essential niche in resource management. Eddie Wilcut, the Water & Energy Efficiency Practice Leader at Plummer , started his career in the Air Force, where he took some classes focusing on water resources. In those classes, Wilcut read Aldo Leopold’s “A Sand County Almanac,” and a specific line has stuck with him for the past 26 years.

It’s a Buoy! Highlighting the New NexSens XB-200 Data Buoy
As scientists seek to better understand aquatic ecosystems, utilizing small data buoys to monitor offshore and cover more water is becoming commonplace. The new NexSens Technology XB-200 data buoy was designed for inland and coastal monitoring applications. Although compact, the platform is designed with adequate space for multiple sensors and measurement electronics. When configured with the NexSens X3 data logger with IoT connectivity, internal batteries, solar panels, select sensors, and other accessories, the new buoy provides an off-the-shelf solution for any monitoring project. The new buoy concept was developed by the NexSens product development team with significant user input.

Predicting and Monitoring Ice Weather Events: The Great Lakes Approach to Ice Research
Ice cover on the Great Lakes provides numerous recreational and economic opportunities, including ice fishing, snowmobile charters, and ice caves on the lakes. Unfortunately, declining ice cover and increasing related weather events due to climate change, as well as other environmental stressors, have put such opportunities at risk. Historically, understanding winter weather has been difficult largely due to a lack of observations and, as a result, communities surrounding the Great Lakes have been left underprepared for extreme events.
