An internationally endorsed Ocean Best Practice (OBP) framework was used to map and classify seabed shapes (Morphology: Dove et al., 2020; Huang et al., 2023). Where sufficient data were available, these shapes were characterised with their geomorphic and process interpretation (Nanson et al., 2023). Supporting data used to inform the geomorphic interpretation included sediment samples, sub-bottom profiles, sediment and hydrodynamic models, insights from published literature, regional analogue examples, and expert interpretation.<div style='font-size:1.2019em; margin:0px 0px 0.75em;'>Currency</div>Date Modified: 29 January 2026Modification Frequency: As needed  <div style='font-size:1.2019em; margin:0px 0px 0.75em;'>Data Extent</div><div style='margin:0px 0px 0.75em;'>Spatial Extent</div>North: -37° South: -41° East: 150° West: 143°  <div style='font-size:1.2019em; margin:0px 0px 0.75em;'>Source information</div>Seabed geomorphological mapping is provided by the Marine and Coastal Geoscience section at Geoscience Australia.The mapping is produced at a 1:1,000,000 to 1:1,500,000 scale.These products are not intended for navigational purposes. <div style='font-size:1.2019em; margin:0px 0px 0.75em;'>Lineage statement</div>Bass Strait geomorphology was mapped using the AusBathyTopo (Bass Strait) 30m 2022 and AusBathyTopo (Bass Strait) 100m 2022 regional scale depth models as input.
