"Momo" is a newly developed drifting buoy with a solar panel.
"Momo" and "Ai" and Tops released on the first August from
offshore of Yonaguni-Island. Slightly After their release, big typhoon hit
release point. Maybe this is one of the reason "Momo" could not catch
the Kuroshio-current. On the other hand drifting buoy "Ai" seems ride
on the Kuroshi-current.
"Momo" released again on the Kuroshio-current after examination.
