Outline of Research at the Start

This project will evaluate hydrodynamic effects on the production and fate of coral mucus and the induced aggregates by combining laboratory experiments, field observations, and reef circulation modeling.

Outline of Annual Research Achievements

In FY2024, I have worked on analyzing the field observation data collected in FY2023 and continued to develop the numerical regional ocean model for this area using CROCO (Coastal and Regional Ocean COmmunity model). I am currently in the process of validating the model before using the model output to explain the results from the field observation. I also published the laboratory experiments that was completed in FY2023 as a refereed journal article on Frontiers in Marine Science.

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

The development and validation of the regional ocean model is taking longer than expected.

Strategy for Future Research Activity

In FY2024, I plan to complete the development of the regional ocean model including coastal processes such as wave-current interactions. After the completion of the model validation, I will be synthesizing the model outputs with the data from field observations.
