Soil moisture is important to agriculture and landscape management and is a frequent topic of research. Advances in sensor technology simplify measurement of multi-point profiles, and NexSens data logging and communication systems relay data for real-time monitoring and tracking of long-term conditions and trends.
While NexSens provides turnkey systems, the CB-Series data buoys are easily customized with user-preferred power supplies, electronics, sensors, accessories and mounting hardware. Buoy Platforms This document covers the CB-450, 650, 950 and 1250 customization. For XB-200 applications, see Customizing the XB-200. When selecting a buoy platform, careful consideration of anticipated sea state, battery and solar […]
Dissolved gases like oxygen, carbon dioxide, and methane are common in surface waters. They play important roles in aquatic ecosystems and impact atmospheric gas concentrations through air-surface flux dynamics. NexSens real-time monitoring systems with dissolved gas sensors can detect acute changes and study long-term cycles and processes.
Waterfront construction projects on lakes, rivers, and coastal areas can impact local water quality. Turbidity is often used as an indicator of changes resulting from construction activity, and monitoring requirements are increasingly being set. NexSens real-time turbidity monitoring systems deliver the data necessary to ensure minimal environmental impact.
Dredging is a common practice for removal of contaminated sediment for remediation under CERCLA, commonly called the “Superfund” program, or for maintenance and expansion of ports, harbors and shipping channels. Real-time turbidity monitoring during the dredging operation provides needed data to aid in decision making and ensure minimal environmental impact.
A refreshing bath to cool off from the hot sun is a favorite pastime for many a beachgoer. Nobody wants their day of fun and sun to turn into a nightmare, but an invisible threat has the potential to do just that: E. coli and other fecal coliform bacteria. Fortunately, NexSens beach E. coli monitoring systems can take real-time measurements and help keep us safe.
Harmful algal blooms (HABs) are an issue associated with eutrophication, the presence of excess nutrients in water. Rapid growth of organisms like cyanobacteria can deplete oxygen levels, increase stratification, and produce harmful toxins. NexSens automated detection systems can help track HABs and predict when potentially hazardous conditions are forming.
Inland lakes are important resources providing habitat, drinking water, recreational opportunity, and more. Human activity and natural processes may threaten lake water quality. NexSens automated monitoring stations detect and provide early warning of acute changes and document long-term trends.
Maintaining oversight of stream and river flows is important in applications ranging from water use management in drought-prone or irrigation-intensive areas to early warning in waterways subject to flooding. Real-time monitoring systems measure flow by recording the water level and mean or index velocity of water flowing through the stream or river.
Tide gauges measure tidal fluctuations, instantaneous water depths and long-term water depth averages in coastal areas. NexSens automated tide gauge systems utilize the latest sensor technology to deliver accurate, comprehensive data for long-term trend analysis, near and long-term forecasting and alerting of extreme conditions.
