Particulate Organic Carbon, Nitrogen, and Chlorophyll as Measures of Phytoplankton and Detritus Standing Crops in Kaneohe Bay, Oahu, Hawaiian Islands

摘要

Data are presented to show that the Kaneohe municipal wastedischarge into the southeastern corner of Kaneohe Bay gives rise to high concentrationsof particulate organic matter and chlorophyll-a. The data cover a periodof 1.5 years and show a continuing increase in particulate organic matter andchlorophyll-a and a significant increase in the particulate organic nitrogen: carbonratio. It is shown that regression analyses of particulate organic carbon and nitrogenon chlorophyll-a can be used to estimate the phytoplankton and the detritus carbonand nitrogen concentrations in surface water samples from the eutrophic southeasternsection of the bay. The differences in regression analyses results on samplesfrom eutrophic waters as opposed to those from ologotrophic waters are discussed.
