Figure 1. Locations are shown of Site 1224 and the Hawaii-2 Observatory (H2O) junction box (large star), Site 1223 (small star), and the location of the Hawaii-2 cable (crosses). Superimposed on the map is the satellite-derived bathymetry. Broadband seismometers have been installed at the OSN1/843B and H2O/1224D sites. The Ocean Seismic Network site (OSN-1) is 225km southwest of Oahu at a water depth of 4407m [Stephen et al., 2003]. The Hawaii-2 Observatory (H2O) is halfway between Hawaii and California on the retired Hawaii-2 telecommunications cable and is at a water depth of 4970m. Spectra from the two sites are compared in Figures 4 and 5.
