Bathymetry maps and site locations. a Regional bathymetry map based on ETOPO1 (Amante and Eakins 2009) with contour lines for seafloor age (Müller et al. 2008). b Bathymetry maps based on the available MBES data for Area A and Area B, respectively. Crosses and squares indicate the locations of sites where OBEMs and EFOSs were deployed. Yellow and red colors denote the sites of the NOMan experiment for which data are available and unavailable, respectively. Green and blue colors indicate the sites included in past experiments (Baba et al. 2010, 2013b). Stars represent the geomagnetic observatories at Kakioka (KAK) and seafloor of the North Western Pacific (NWP) (Toh et al. 2006)
