Installation of seafloor geodetic observation system on the S/V Shoyo

Abstract

The Japan Hydrographic and Oceanographic Department（JHOD）installed an acoustic transducer on the bottom of the S/V Meiyo（550 tons in March 2008, the S/V Takuyo（2, 400 tons）in February 2010, and the S/VKaiyo (550 tons) in March 2012 and started sailing measurements. JHOD also installed a new seafloor geodetic observation system on the S/V Shoyo（3,000 tons in November 2012 for more efficient and precise seafloor positioning. In this report, we present the new system mounted on the S/V Shoyo and the test results through the comparison with the results obtained by other S/Vs.
