Next week, the Seniors (4th year students) are giving their thesis presentations.

So this year, I have one 4th-year student working on her thesis. She has been examining dispersion in small canopies of Sargassum thunbergii (ウミトラノオウ), and has also added some marine catfish to the experiment to see what they do to the water.

Apparently the dispersion rates increased with increasing density of Sargassum, and the fish only contributed to dispersion when the density of Sargassum was low.

This is the experiment done in the acrylic flow-chamber.

This is a small group of Sargassum thunbergii at our field site.
