Title: Probing the Australian-Pacific Plate Boundary: Macquarie Ridge in 3-D
Voyage details on MNF site: https://mnf.csiro.au/en/Voyages/IN2020_V06
Period: 2020-10-08 01:00 to 2020-11-02 21:20 UTC
Duration: 25.85 days
From: Hobart To: Hobart
Ship: Investigator (RV) [details]
Description: The primary objectives of the voyage are to acquire passive seismological data that will enable us to:
- Characterise the 3-D structure of the oceanic crust and sub-crustal lithosphere along the Macquarie Ridge Complex (MRC) with novel lithospheric seismic imaging. This includes teleseismic receiver function analysis, teleseismic and ambient noise tomography, joint inversion of receiver functions and ambient noise dispersion, shear wave splitting analysis, autocorrelation analysis, and enhancing of regional and teleseismic wavefield through array seismology.
- Describe the structural, thermal, and compositional nature of the central MRC by applying a range of seismic imaging techniques to identify velocity anomalies in the crust and mantle. This is possible because 2-D or 3-D images of velocity anomalies in the crust and mantle may be interpreted as structural, thermal, or compositional variations.
- Define sites for OBS deployments in the vicinity of Macquarie Island using multibeam sonar and sub-bottom profiling data. Pending scheduled testing later this year, deployment parameters are tentatively in water depths =1000 m and on gentle seafloor slopes, ideally flat, but not to exceed 30°. Sediment cover is preferred over bare igneous rock for OBS deployment. Existing data around Macquarie Island are not of sufficient quality to define deployment sites.
- Characterise the neotectonics, structure, and stratigraphy of the active Australian-Pacific plate boundary in the vicinity of Macquarie Island using multibeam sonar (both bathymetry and backscatter), sub-bottom profiling, gravity, and magnetics data. These data will also provide critical baseline information for benthic habitat mapping.
