| Research Abstract |
Marine humic-like fluorescence has been suggested to be useful for biogeochemical parameter such as apparent oxygen utilization and can be determined using in situ fluorometer. However, application of in situ fluorometer to monitoring the marine humic-like fluorescence in open ocean has not been conducted. In the present study, we firstly applied an in situ fluorometer for open ocean and found that the in situ fluorometer is enough for sensitive to monitoring the distribution of marine humic-like fluorescence with high resolution. Even though further examinations are necessary, marine humic-like fluorescencedetermined by in situ fluorometer is able to be new biogeochemical parameter.
