The goal of this project was to identify submarine groundwater discharge locations and quantify groundwater and its derived nutrient flow into Kāneʻohe Bay, particularly as it varies with wet and dry seasonal cycles. The researchers found that most freshwater in nearby coral reefs derives from streams during the wet season, but during the dry season, input from groundwater increases 150%. These results have led to maps with quantification of groundwater discharge, and measurements of nutrient fluxes have identified several watershed hotspots of wastewater contamination.
