Coastal & Estuary

Measurement of water quality in coastal regions and estuaries is critical in the characterization of hypoxic ‘dead zones’ as a result of nutrient loading and algal blooms in the water bodies. Sediment loading analysis through turbidity measurement is also important for coastal trend identification and modeling. Hydrolab and Sea-Bird Scientific offer a variety of multiparameter water quality instrumentation and nutrient sensors for long-term coastal applications. Sea-Bird Scientific water quality multiparameter sondes are developed to provide accurate data in environments with salt water and biologically rich environments. Developed for longterm deployments.

Certain OTT level sensors (OTT RLS, OTT SE 200) are effective for sea level and tide level monitoring with radar and float pulley technology. Additionally, certain OTT groundwater level sensors can measure salinity and conductivity for detection of saltwater intrusion in freshwater coastal aquifers.
