  • Why are we monitoring nutrients at different depths?

    Recently, LG Sonic introduced the MPC-Lab, an innovative monitoring buoy that can monitor algae, physico-chemical variables, and even nutrients such as nitrogen and phosphorus in near real-time and at different depths in a body of water. Combined with our other monitoring tools, this system offers a unique way to detect the spatial and temporal patterns of nutrient concentrations which play a ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Map algal blooms with satellite remote sensing technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Assessing and monitoring agroenvironmental determinants of recreational freshwater quality using remote sensing

    Diverse fecal and nonfecal bacterial contamination and nutrient sources (e.g. agriculture, human activities and wildlife) represent a considerable non-point source load entering natural recreational waters which may adversely affect water quality. Monitoring of natural recreational water microbial quality is most often based mainly on testing a set of microbiological indicators. The cost and ...

  • Scottish Water Flow Monitoring Contracts

    Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland. One project involved the installation of reservoir level, inflow flow gauges and recording raingauge devices in nine reservoir catchments in South West Scotland. Although ...

  • Remote Sensing Techniques to detect Surface Water Quality Constituents in Coastal and Inland Water Bodies from Point or Non Point Pollution Sources

    This study demonstrates that point and non-point pollution sources in coastal and inland water bodies can be identified and monitored using remote sensing techniques so early corrective action can be take to prevent or minimize Harmful Algae Blooms (HAB’s). By tracking these changes in the remote sensing images could be very beneficial in establishing cleanup and restoration efforts for improving ...

  • Salmon Stream Warm Water Monitoring - Cook Inletkeeper - Case Study

    Cook Inletkeeper is a community-based nonprofit organization that combines advocacy, education and science toward its mission to protect Alaska’s Cook Inlet watershed and the life it sustains. The Cook Inlet watershed is the most populated and fastest-growing region in Alaska; it is also home to the state’s renowned wild salmon runs, some of which are at great risk due to climate and ...

  • Assessing large spatial scale landscape change effects on water quality and quantity response in the lower Athabasca River basin

    Increased land use intensity has been shown to adversely affect aquatic ecosystems. Multiple landscape stressors interact over space and time, producing cumulative effects. Cumulative Effects Assessment is the process of evaluating the impact a development project may have on the ecological surroundings, but several challenges exist that make current approaches to cumulative effects assessment ...

  • Unmanned remote and wireless CDM monitoring case study

    Remote and wireless monitoring technology to meet CDM requirements is in its infancy in Europe. Carbon trading is driving it globally, especially in North and South America. That experience and technology is now finding a demand in Europe and Asia in landfill, biogas from food and animal waste in digesters and water treatment sludge digestion. Methane recovery from landfill and anaerobic ...

  • Salinity monitoring in western Australia using remotely sensed and other spatial data

    Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in pockets of remnant vegetation and biodiversity, and reduction in water quality. Accurate information on the location and rate of change of the extent of ...

  • LG Sound integrates new technology to detect toxic algae blooms

    LG Sound introduces satellite remote sensing technology in order to detect toxic algae blooms. Satellite remote sensing allows for detection of water quality from a distance with information obtained from satellites. Together with several European universities we discovered that different types of algae require different types of ultrasonic treatment. Therefore, it is important to detect ...
