Abstract:
Since the mid-1990s, we (Hydrographic and Oceanographic department, Japan Coast Guard) have been developing the combined Global Navigation Satellite System-Acoustic ranging (GNSS-A) technique for realizing seafloor geodesy. This technique allows us to collect time series of seafloor crustal deformation. In this dataset, we published our original data obtained from 2001 to Aug. 2017. Our data can be used to investigate several seismological phenomena along the subduction zones around Japan, namely the Nankai Trough, Sagami Trough and Japan Trench. These regions are globally important places in geodesy and seismology and are also suitable for comparison with other geophysical datasets.
