During underwater monitoring observations in shallow water for coastal environmental conservation, the sea is not always clear and waves and current make the observational situation difficult. Underwater monitoring is still conducted mainly by human divers. Therefore, underwater robotics or remotely operated underwater vehicles (ROVs) that can monitor from(More)
Herein, three oscillating fin propulsors connected in a parallel and in a staggered arrangement were investigated to develop an environmental-friendly and energy-saving propulsor. In this study, the flow pattern induced by these fish-like propulsors was achieved with a low Reynolds number and was measured using the particle image velocimetry (PIV)(More)
at figuring out the oceanic water intrusion in Kagoshima bay for each season by satellite SST(sea surface temperature) and chl-a(chlorophyll-a) images using the MODIS/Aqua ocean color sensor. It is relatively easy to find the oceanic water intrusion in winter by satellite SST images. However, it is difficult to find it during the summer season considering(More)
The periodic Kuroshio Current brings a water intrusion into Kagoshima bay in Japan, known as the 'Kyucho' phenomena. This oceanic water, influenced by the Coriolis Effect, intrudes at about 12cm/s. It is assumed that the water quality in Kagoshima Bay is affected by this phenomenon. However, even though the influence on the water quality by intermittent(More)
