Description: A SediMeter™ instrument and temperature sensors were deployed in Lago Yojoa to measure sediment resuspension during the annual fall mixing event which frequently causes anoxia and fish death. The normally oligotrophic lake is now used for fish farming. Unfortunately theft of hardware by local boaters sabotaged the project repeatedly, and while a stolen cable was replaced by ...
Watr’s technology can be utilised in a variety of different environments around the world, we can install Watr in lakes, rivers and reservoirs as well as other large open expanses of water. The Case Studies below are examples of how Watr can be used to solve real world problems and how it’s technology could be preventative to future devastating events. The Highbridge Lake Fishery in ...

Almost half of the population of Ontario relies on Lake Ontario for their drinking water. Source water from the great lake must be monitored and protected constantly to ensure chemical and biological agents remain below the accepted limits. Despite best efforts, it is possible that natural organic matter (NOM) can still exist in our drinking water. General methods of determining NOM are by ...
Time: June 2015 Equipment: ESM30 USV, portable monitoring instruments Main Process: Wuhan City plans to conduct water quality surveys on 53 lakes. We use the ESM30 USV to collect water samples from lakes, and monitor and record water quality parameters PH, temperature, dissolved oxygen, conductivity, and turbidity online. Survey result: 1. Collected 673 pieces of water samples from 53 ...
In June 2015 the first European Games will be held in Baku, Azerbaijan. Eijkelkamp Soil & Water is supplying and installing equipment which will monitor the water quality and water quantity in Lake Boyuk Shor, to the north of the city, after the European Games. Part of a major remediation project The delivery and installation of the water quality and water quantity equipment by Eijkelkamp ...
Teshekpuk Lake is the largest lake in the Alaskan Arctic and the third largest lake in the state. Given the importance of this region to an abundance of native wildlife and expected environmental changes associated with projected sea-level rise, coastline erosion and oil and gas development, the Teshekpuk Lake Observatory (TLO) was established as an effort to gain a better understanding of this ...
Alaska’s North Slope is often associated with cold weather, permafrost and oil production, however it is a diverse and beautiful landscape stemming northwards from the Brooks Range that supports an immense range of wildlife with its plethora of freshwater lakes. Researchers from the University of Alaska, Fairbanks and the USGS, are looking at how regional changes in climate are influencing ...
Time: June 2015 Equipment: sample collection monitoring USV , portable monitoring instruments Take the water quality survey of 53 representative lake in Wuhan. Collecting and recording sample automatic from these 53 lakes by USV, monitoring and recording water quality, PH, temperature, dissolved oxygen, conductivity, turbidity online, The results of the survey: Collect 673 water samples from ...
Background Wuhan is the capital city of Hubei province in central China and has 166 lakes that cover 2,217 square km (856 square miles) and approximately 25% of the city. This surface water coverage is one of the world’s highest. The Wuhan Environmental Protection Bureau (WHEPB website: http://www.whepb.gov.cn) is responsible for monitoring the surface water quality within the city ...
Virkisjökull is a rapidly retreating glacier in south-east Iceland. A proglacial lake has formed in the last ten years underlain by buried ice. In this study we estimate water velocities through the glacier, proglacial foreland and proglacial river using tracer tests and continuous meltwater flow measurements. Tracer testing from a glacial moulin to the glacier outlet in September 2013 ...
We now have much more robust data available on the amount of water in lakes worldwide thanks to a comprehensive database created by researchers at McGill University in Montreal. The McGill scientists discovered the total shoreline of the world’s lakes is more than four times longer than the global ocean coastline. At 7 million kilometers, this is 10 times the distance from the Earth to the ...
Marine researchers around the world are utilizing Deep Trekker Underwater Drones (or ROVs) in their marine projects; here are the top 5 applications being used today. In a few weeks, the world will gather in San Diego, California for the Oceanology International North America exhibition. It will bring together water industry professionals, manufacturers, educators, government representatives and ...
Although mixing in lakes has significant environmental and ecological implications, knowledge of mixing dynamics for shallow floodplain lakes has received little attention. In this study, hydrological, thermal and isotopic investigations were undertaken to provide evidence for the mixing in the large, shallow floodplain Poyang Lake (China). Depth profiles of water velocity, water temperature ...
Large flow-through reservoirs and lakes possess environmental gradients and monitoring programs are mostly adapted for cost and time effectiveness. Bay areas are often more isolated from the main water body and are likely to have unobserved different environmental processes and impacts. This study was performed at the Itaparica Reservoir, São Francisco River, located in semi-arid Northeast ...
Turbidity, along with Suspended Solids, is a way of measuring the clarity of a body of water, and how many particles are affecting it. The difference is that while Suspended Solids describes the density of the materials in the water, Turbidity describes how those materials affect light passing through the water. Turbid water can appear cloudy and discoloured because the more particles in the ...
As part of the Clearwater PMPC project, 2 MPC Buoys were deployed in the Skrzyneckie Małe Lake to test the performance of this unique technology. The Challenge: Control and Monitor Toxic Algal Blooms The ClearWaterPMPC project was initiated by LG Sound and funded by "Research for SMEs" within the EU 7th Framework Programme. The goal of the ClearWaterPMPC (Predicting, Monitoring,Preventing, ...
Bournemouth Water has installed four MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. After the installation of the MPC-Buoy systems a dramatic reduction in the concentration of algae was experienced. The Challenge: Installing an Environmentally Friendly Solution to Control Algal Blooms The objective of the project was to reduce algae concentrations . Algae growth in the ...
A long-term satellite-based analysis was performed to assess the impact of environmental factors on cyanobacterial harmful blooms (CyanoHABs) dynamics in a typical shallow lake, Lake Taihu. A sub-pixel approach (algae pixel-growing algorithm) was used with 13 years of MOderate-resolution Imaging Spectroradiometer (MODIS) data to evaluate changes in bloom extension, initiation date, duration, ...
LG Sonic installed four ultrasonic algae control systems, the MPC-Buoy, in recreational lake “de Zoetermeerse Plas” located in South Holland, the Netherlands. This environmentally friendly system controls toxic algal blooms by using ultrasound technology. It is the first algae control project of LG Sonic in their domestic market. In December 2015 LG Sonic, the municipality of ...
