Geosyst., 13, Q10011, doi:10.1029/2012GC004201. Introduction: The auxiliary material file Text S1 contains two sections, A and B. Section A includes one table (Table S1 listing the station information) and two figures Figure S1 (the collection of OBS PDFs which are not displayed in the main text) and Figure S2 (maximum amplitudes of double-frequency microseism peak vs. station depths for both west and east stations). Section B includes the text explaining the normal mode calibration for OBS seismic sensors, three figures (Figure S3 to S5) and two tables (Table S2 listing the event information which are used for the calibration and Table S3 listing the averaged calibration factor for each station). 1. 2012gc004201-txts01.pdf Text S1. Collection of PDFs, plots of maximum double-frequency peak amplitudes, and the station list and normal mode calibration of MOANA OBS.
