  • Multibeam data from the "OS2020 Southern Hikurangi Margin 1" voyage by the R/V Tangaroa. This is the first of several voyages whose overall purpose is to complete high resolution multibeam mapping of the Southen Hikurangi Margin to analyse the detailed geomorphic expression of tectonic and sedimentary processes. These voyages aim to aid hazard research in terms of earthquake and tsunami source parameters (both landslide and fault sources) and underpin future exploration initiatives.
