Broadband seismic data collected as part of the Macquarie Ridge experiment from 2020-2021. OBSs were deployed around Macquarie Island, while terrestrial stations were deployed on Macquaire Island itself. The data sources are as follows: (1) 3-component broadband data from 10 IGGCAS stations with 60s corner period, plus hydrophone data. (2) 3-component broadband data from 5 Guralp Libre stations with 60s corner period, plus hydrophone data. (3) 3-component broadband data from 5 Guralp Certimus stations located on Macquarie Island. Four instruments only recorded for ~2 months, while the remaining instrument managed about 8 months of recording. Further details on the experiment can be found in Tkalčić, H., C. Eakin, M. F. Coffin, N. Rawlinson, and J. Stock (2021), Deploying a submarine seismic observatory in the Furious Fifties, Eos, 102, https://doi.org/10.1029/2021EO159537.

This is the raw data collected by the stations of the UK National Seismometer Network. Continuous data is stored as day long miniSEED files on the Edinburgh LINUX filesystem. Data is present for 170 past and present stations, with the oldest data dating from 2001 and new data being added in near real-time. This data is accessible via the BGS EIDA node (eida.bgs.ac.uk). The waveform files are accompanied by metadata that allows the raw data to be converted to useful units, as well as the location of the stations. All stations are indexed but not all are still active and will be flagged accordingly.
