Gifford Marine Park Bathymetry Flythrough Video

Flythrough movie visualizes the seafloor bathymetry of Gifford Marine Park, located 700 km east of Brisbane. Data was collected during two surveys by Geoscience Australia in 2007 and 2017, in collaboration with the Japan Agency for Marine-Earth Science and Technology. The park features two large, flat-topped volcanic seamounts rising over 3 km from the abyssal plain.

Use Cases

• Analyze seamount morphology, including summit sediment veneers and steep cliff features, for geological studies.
• Study the distribution of bedform fields and mass movement scars to understand sediment dynamics.
• Use bathymetric depth data to model potential habitats for humpback whales, sperm whales, and other migratory species.
• Compare 2007 and 2017 survey data to assess changes in seafloor features over a decade.

Strengths

• Data spans a significant depth range of over 3 kilometers.
• Combines bathymetric surveys from two distinct time points (2007 and 2017).
• Covers a specific, ecologically significant area within the Lord Howe Rise seamount chain.

Limitations

• Primary data format is a video flythrough, limiting direct quantitative analysis of raw bathymetric grids.
• Specific technical details like resolution, coordinate reference system, and data processing methods are not provided.
• The dataset's focus is a single marine park, limiting broader regional analysis.
