Abstract
We operated the Wave Gliders to observe the surface water temperature and wave height at Hwajin-ri and Josa-ri on the coast of Pohang from March 24th to April 3rd, 2017 for 11 days. Wave Glider Sv2 and SV3 were respectively operated within a radius of 100 m at the two sites in the depth of about 30~40 m. Both vehicles are equipped with weather sensor, wave height sensor and camera. Additionally, C/T sensor and chlorophyll sensor were equipped in SV2. During the observation period, the average of surface water temperature and significant wave height were 13.0 ºC and 0.7 m. We compared the observation results of Wave Gliders with KMA(Korea Meteorological Administration) buoy. The differences of the surface water temperature and the significant wave height were within 0.5 ºC and 0.03 m, respectively. This study confirms that wave gliders can be used on the coast with high currents of about 1 to 2 knots and low depths of about 30 to 40 meters,a radius of 100 m at the two sites in the depth of about 30~40 m.
