| Summary: | Progress Code: completed Statement: Note for the user: they should rely on the CDPs rather than shotpoints for considerations regarding the horizontal scale. Purpose This MCS dataset has been acquired for the investigation of tectonic, magmatic, and geodynamic processes regulating the rift evolution of William's Ridge (Central Kerguelen Plateau) and Broken Ridge. The geophysical dataset is important for the collaboration with Geoscience Australia, the Department of Foreign Affairs and Trade (DFAT), and the Attorney-General's Department (AGD) on preparing an anticipated submission for William's Ridge Extended Continental Shelf (ECS) to be considered by the United Nations Commission on the Limits of the Continental Shelf (CLCS) under the United Nations Convention on the Law of the Sea (UNCLOS). The Multichannel Seismic Reflection (MCS) dataset has been collected during RV Investigator voyage IN2020_V01 (Development of William's Ridge, Kerguelen Plateau: tectonics, hotspot magmatism, microcontinents, and Australia's Extended Continental Shelf). The geophysical dataset images the upper crustal structure of William's Ridge (Profiles 0001-0004) and Broken Ridge (Profiles 0005-0009). The SEG-Y format is a standard file format for storing geophysical data like multichannel/single channel seismic reflection profiles. An open source software commonly used for the visualization of the SEG-Y file is SeiSee (https://seisee.software.informer.com/). The vertical scale is displayed in Two-Way Travel Time (TWT - seconds/milliseconds) The spatial coordinates are UTM (Easting - Northing) - Common Depth Point (CDP)
