Hydroacoustic catalogs along the Central Indian Ridge

We present the hydroacoustic event catalogs associated with seven seismic swarms in 2013 and 2020 along the Central Indian Ridge. These swarms are recorded by a network of 6 to 8 autonomous underwater hydrophones of OHASISBIO network and three permanent hydroacoustic stations maintained by International Monitoring System of Comprehensive Nulcear Test-Ban-Treaty organization. Out of four swarms, two swarms occur near the Kairei hydrothermal field, one along the CIR segment at 21°S and the last near the Edmond hydrothermal field.
