Contour intervals are every 10 m from zero to -100 m, every 25 m from -100 m to -500 m, and every 100 m from -500 m to full depth. The DEM utilized was the Global Multi-Resolution Topography Synthesis which is a multi-resolution gridded global Digital Elevation Model that includes cleaned processed ship-based multibeam sonar data at their full spatial resolution (approximately 100m in the deep sea)","collection_id":1,"tags":{"inventory_name":"bathymetric-contours","categories":["Natural Hazards","Transportation Water"]},"created_at":"2026-02-15T07:10:06.307910","updated_at":"2026-02-15T07:10:06.307930","files":[{"id":4190,"name":"bathymetric-contours","description":null,"source_file_path":null,"created_at":"2026-02-15T07:10:06.452786","dataset_id":3435,"slug":"bathymetric-contours-bathymetric-contours","layer_name":null,"file_metadata":null,"updated_at":"2026-02-15T07:10:06.452807","formats":[{"format_count":5}]}]}}
