... effects of capes and offshore islands as well as refraction and breaking on shallow-water bathymetry. Recently wave buoys equipped with RTK-GPS rovers (GPS buoys or GB) are being installed normally at 100 400 m in water depth and 10 20 km from the coastal line (Kawai et al., 2012, 2013b). The various...

... ABSTRACT This paper summarizes wave characteristics acquired by GPS buoys at a spot of 100–400 m in water depth and ultrasonic wave gauges on a 20–60 m deep seabed, around Japan in 2007–2012. The spatial variations in monthly wave statistics among the GPS buoys off the Pacific coast of Tohoku...

... ABSTRACT: The tidal anomaly increased relatively slowly and quickly in the initial and subsequent part, respectively, of the first crest and consequently exceeded 6 m at the GPS buoy off Kamaishi Port. The tsunami was observed even in semi-closed bays on the East China Sea coast of the Kyushu...

... at offshore tsunami observation stations around Japan, such as GPS buoys (e.g., Kato et al., 2005) and cabled ocean-bottom pressure gauges (e.g., Meteorological Research Institute, 1980). Tsunami heights exceeded 5 m at offshore observatories near the tsunami source. For example, a water rise of 6.7 m...

... ABSTRACT: The 2010 Chilean Tsunami has been observed on the Japanese coast by eleven GPS buoys of NOWPHAS. These GPS buoys measured water level by the RTK-GPS technology at a location of 100–300 m in water depth. The highest tsunami crest was 0.1–0.3 m and the predominant period was longer...

... of monitoring methods, Smallsized GPS Buoy for coastal area and PVD (Point precise Variance Detection) Wave Monitoring Unit, have been developed. The Smallsized GPS Buoy is characterized by its cost-efficiency and simplicity. The PVD Wave Monitoring Unit based on PVD method can be attached on floating fish...

... an example of offshore buoy station to measure the wave condition off the west island (Shikoku) in Japan. The heaving motion of buoy is obtained by GPS (Global Position System) and recorded in a main station located on the main island. The GPS buoy system becomes a tool suitable to measuring offshore waves...

... ABSTRACT This paper presents observation results and numerical analysis of offshore wave, tsunami and tide based on the data obtained during Apr- Sept 2007, by two sets of GPS buoy system installed off the Northern Pacific Coast of Japan These two sets of the GPS buoy successfully observed...
