We aim to convert an existing autonomous instrument for phosphate monitoring into an instrument for urea monitoring and integrate the effort with ongoing research to understand, detect and mitigate HABs in Maryland. This will require equipping the existing instrument with a colorimeter/heater in the 520-530 nM range with a higher temperature (~85 degrees vs 50 degrees) capability; optimizing existing urea determination and standardization protocols for interfacing with our instrument; testing the instrument in the laboratory; deploying the instrument in the field; posting the urea data on web sites; and describing our results to colleagues, environmental managers, and the public.
