How the CAROSEL fills a major gaps in your water quality management program

Nutrients enter water from surface runoff, groundwater, and sediments, causing Harmful Algal Blooms that cause human, economic, and ecosystem detriment.

Despite interventions such as nutrient Best Management Practices, Harmful Algal Blooms are worsening globally due to fluxes from accumulated legacy sediment nutrients.

The CAROSEL can be installed to monitor daily the benthic fluxes of phosphate, ammonium, and nitrate, with maintenance approximately monthly from a dock or small boat
*simulated data
The system will not only monitor sediment-derived nutrients, but also measures water column localized nutrient fluxes, e.g. those formed from respiration or particle desorption
*simulated data
Water column ambient nutrient concentrations are periodically measured, allowing determination of the relative importance of the sediment inputs (i.e. water column turnover times with respect to the sediments).
*simulated data
Advanced web-analytics provide additional functionality, including the ingestion of outside data streams such local river nutrient inputs, ultimately allowing the CAROSEL to provide advanced warning of an encroaching or intensifying bloom while also informing the appropriate mitigative approach, e.g. if sediments should be treated.
