Estimating the magnitude of the export of dissolved inorganic and organic nitrogen from Nu‘upia ponds to Kane‘ohe Bay
John Stimson, PI


The southern basin of Kane‘ohe Bay has two main sources of dissolved inorganic and organic nitrogen, the streams which flow into the Bay and the tidal outflow from the Nu‘upia ponds. The magnitude of the export of nutrients from the ponds to the Bay has never been estimated but could be significant given the elevated concentration of DIN and DON in the ponds bordering the Bay. HCRI will fund Dr. John Stimson and Dr. Fenny Cox to study the pond’s DIN and DON concentrations, the rate of export of these nutrients from the ponds, and the direction of movement of the discharged pond waters within the southern basin of the Bay. Since there are few entities which control the lands bordering the ponds, any evidence of high nutrient output from the ponds could be addressed efficiently through altered management practices.
