  • The Thermal Probe—Measurement of the Thermal Conductivity and Drying Rate of Soil in the Field

    The thermal probe is a metal rod with an internal heating element and temperature sensor. In the field it is pushed into a predrilled hole in otherwise undisturbed soil, and the thermal properties of the soil are estimated from the temperatures recorded at intervals after a constant power is supplied to the heating element. The following are discussed in this paper: the theory behind the methods ...

  • Stevens Hydra Probe Furthers Scientific Research at Alabama A&M

    For more than a decade now, the Stevens Hydra Probe has been an important data collection instrument used in The Soil Climate Analyses Network (SCAN). The SCAN Program helps scientists study soil moisture and temperature variability at different time scales and under different land uses and land covers. Studies that involve the SCAN program benefit the environmental science community as well as ...

  • Evaluation of the Stevens HydraProbe Temperature Measurements from -30 to +40 Degrees Celsius

    Soil temperature data down to -30° Celsius is becoming more and more relevant to climate studies. While environmental issues fuel the development and the widespread use of sophisticated environmental models, reliable input data is becoming essential for researchers and modelers. The soil temperature data collected by ...

  • Plot-scale assessment of soil freeze/thaw detection and variability with impedance probes: implications for remote sensing validation networks

    Several large in-situ soil moisture-monitoring networks currently exist over seasonally frozen regions that may have use for the validation of remote sensing soil freeze/thaw (F/T) products. However, further understanding of how the existing network instrumentation responds to changes in near surface soil F/T is recommended. This case study describes the results of a small plot-scale (7 × 7 m) ...

  • Soil Moisture Applications and Practices Using the HydraProbe Soil Moisture Sensor

    Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. Monitoring soil ...

  • Response of rock-fissure seepage to snowmelt in Mount Taihang slope-catchment, North China

    The complex physiographic and hydrogeological systems of mountain terrains facilitate intense rock-fissure seepages and multi-functional ecological interactions. As mountain eco-hydrological terrains are the common water sources of river basins across the globe, it is critical to build sufficient understanding into the hydrological processes in this unique ecosystem. This study analyzes ...

  • Specific PCR Assays for the Detection and Quantification of DNA from the Biocontrol Strain Trichoderma harzianum 2413 in Soil

    Strain identification in situ is an important factor in the monitoring of microorganisms used in the field. In this study, we demonstrated the use of sequence-characterized amplified region (SCAR) markers to detect genomic DNA from Trichoderma harzianum 2413 from soil. Two primers (SCAR A1/SCAR A1c) were tested against DNA of 27 isolates of Trichoderma spp. and amplified a 990-bp fragment from T. ...

  • Design and Evaluation of a Flow Pump System for Column Testing

    The design of the equipment components of a flow pump system for the measurement of solute (effluent) breakthrough curves from soil columns is described. In addition, the performance of the system in terms of the effects of equipment components and temperature on measured differential pressure fluctuations across soil specimens is illustrated. The flow pump for the system provides continuous flow ...

  • First State-funded cleanup using electrical resistivity heating technology

    The Remediation and Redevelopment Division (RRD) completed remediation at a former dry cleaning facility in the city of Owosso using electrical resistivity heating (ERH) technology. Electrical resistivity heating is an in­situ electrical heating technology that uses electricity and applies it into the ground through electrodes. The resistance of the electricity traveling through the ground ...

  • Polluted sites: Groundwater decontamination requires robust level sensors

    Whether it be old landfills, coal tips, former military sites or refineries, what remains behind is contaminated ground, which is a danger to both humans and the environment. In the rehabilitation of these sites, level sensors are required which are resistant to the often aggressive hazardous substances encountered.  Contaminated sites are not only characterized by adverse health or ...

  • Gill Instruments case study featured in AWE International

    AWE International magazine, which is focused on the environmental analysis industry, recently featured Gill Instruments in a case study about environmental monitoring with solid-state meteorological instruments. The case study includes information about all of the products within the Gill Instruments range, with information about their advantages within the environmental analysis field. We have ...

  • The Basics of Evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, watershed level budgeting, and ...

    Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

  • New laser-based dust emission monitoring system

    Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...
