- How Immersion Time Drives Optical Window Fouling in Freshwater LakesOptical turbidity monitors and suspended-solids sensors can provide valuable information about changing water quality, but their readings depend on more than…
- Measuring sediment plume dispersion from deep-sea mining with optical sensorsDeep-sea mining operations can disturb fine sediment on the seafloor and create plumes that travel well beyond the excavation area. The visible cloud may be…
- Autonomous profiling with a winch-integrated turbidity sensorAn autonomous water-quality profiler can turn a fixed sampling point into a moving, depth-resolved observatory. By lowering an optical turbidity sensor through…
- Practical Guidelines for Storing and Retrieving High-Frequency Turbidity RecordsHigh-frequency turbidity monitoring produces a detailed account of changing water conditions, from short sediment pulses around a dredge to daily fluctuations…
- Suspended-Solids Sensors for Jetty and Harbour ConstructionBuilding a jetty, wharf or harbour extension can disturb seabed material that has remained stable for decades. Piling, dredging, trenching, rock placement and…
- Optical detection of algal blooms with chlorophyll and turbidityHarmful algal blooms can develop quickly, spread across connected waterways and change in appearance as cells grow, die or become mixed through the water…
- Interpreting turbidity time series during storm eventsStorms turn a relatively stable water-quality record into a fast-moving account of erosion, runoff, transport and deposition. A turbidity sensor may register a…
- Choosing anti-biofouling protection for long-term turbidity loggingLong-term turbidity logging is rarely limited by the optical measurement itself. In rivers, estuaries, reservoirs and coastal waters, algae, bacteria, silt and…
- Calibrating optical groundwater profilers in variable water chemistryGroundwater rarely presents a chemically uniform target for an optical instrument. A profiler may move from fresh recharge to mineralised water, encounter a…
- Deploying Turbidity Sensors Over Shallow Sandy BedsBest practices for deploying turbidity sensors in shallow, high-sand-bed environments begin with understanding that the bed is part of the measurement system.…
