Gifford Marine Park: Seafloor Bathymetry Flythrough

Bathymetric data from 2007 and 2017 surveys visualizes the Gifford Marine Park, located 700 km east of Brisbane. The flythrough movie depicts two large, flat-topped volcanic seamounts on the Lord Howe Rise, spanning over 3 km in ocean depth with features like sediment veneers, bedforms, and steep cliffs. This data supports studies on the park's role as potential habitat for cetaceans and highly migratory pelagic species.

Use Cases

• Visualizing seamount geomorphology based on detailed bathymetric surveys
• Studying potential cetacean habitats (e.g., humpback whales, sperm whales) based on described breeding and feeding grounds
• Analyzing sediment transport and bedform fields on the gently sloping seamount summits
• Mapping the extent of mass movement scars and steep cliffs encircling the volcanic structures

Strengths

• Data is derived from two dedicated bathymetric surveys conducted in 2007 and 2017, providing temporal depth
• Surveys were conducted by authoritative institutions: Geoscience Australia and the Japan Agency for Marine-Earth Science and Technology
• Dataset is associated with a specific research project (NESP Marine Biodiversity Hub Project D1), indicating a research-grade source

Limitations

• Core data attributes like column names, row counts, and file size are consistently listed as unknown or 'None' across all platform entries
• License and author information is missing, limiting clarity on reuse permissions
• The primary data format is a processed video (MP4), which may limit direct quantitative analysis compared to raw bathymetric grids
