Attending the JOS 2016 Fall Meeting at Kagoshima University
By admin In Meeting, REPORT On 2016-09-23
I presented a poster focusing the distribution of gel particle in meso- and bathypelagic ocean at JOS (The Oceanographic Society of Japan) Fall Meeting (11–15 Sep).
On 14th September, Dr Yamada gave an oral presentation on particle size distributions and their regulation factors in Kuroshio region in Session 16F_I02 focusing on Kuroshio’s marine environments and biological production.
Particle size distribution (PSD) is thought to be reflected from phytoplankton community structure in marine environments. PSD slope, which indicates relative contribution of small and large particles, is used for the comparison of particle groups in different marine environments. In this study, we measured particle volume in Kuroshio region by Laser In-Situ Scattering and Transmissometery (LISST) to calculate PSD slopes and compared them with other parameters. Our data indicated that the value of PSD slope was inversely proportional to the concentration of Transparent Exopolymer Particles (TEP) significantly, which suggested that TEP might play an important role in the regulation of PSD slopes in this region. We need further study for the determination of the regulation factor of PSD slopes.

A little break with “Shirokuma shaved ice” that Kagoshima is noted for.
