Examination of macroalgal bioindicators and coastal water quality during July 2001 - July 2002, in Hawaii, in support of the Kaneohe Bay Nutrient Enrichment Study (NODC Accession 0000428)

This project assesses the physiological status of selected macroalgae in Hawaii under various nutrient regimes, with the purpose of determining a suitable physiological test that can, with reasonable accuracy, define nutrient concentrations in the adjacent water column. The project is designed to test the utility of pulse amplitude modulated (PAM) fluorescence as a means of assessing physiological status. PAM fluorescence provides an estimate of photosynthetic efficiency and can be measured underwater in the field. This technique may be suitable for resource managers seeking to rapidly assess nutrient concentrations in the marine and aquatic environment. The data were taken from July 2001 - July 2002.
