This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. Australia's marine jurisdiction offshore from the territory of Heard and McDonald Islands and the Australian Antarctic Territory are not included. \nThe new map provides a complete three-dimensional picture of the seafloor and is a significant improvement since it was last revised in 2009. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve coastline definition and present a seamless transition between land and sea. The data is compiled from 1582 individual surveys using multibeam echosounders, single-beam echosounders, LiDAR, or 3D seismic first returns, as well as higher-resolution regional compilations, and other source data including Electronic Navigation Charts and satellite derived bathymetry. The new map represents decades of data collection, analysis, investment and collaboration from Australia\u2019s seabed mapping community.  \nThe 250 m resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist). In many regions, this 250 m grid size is far in excess of the optimal grid size for some of the input data used. \nThe AusBathyTopo250m grid and higher-resolution regional datasets are available on the AusSeabed Marine Data Portal as the AusBathyTopo Series.  \nThis map is not suitable for use as an aid to navigation, or to replace any products produced by the Australian Hydrographic Office. \nMedium: Digital PDF download.", "num_resources": 1, "num_tags": 11, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/australias-seabed-map-2023", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[92.0, -60.0], [172.0, -60.0], [172.0, -8.0], [92.0, -8.0], [92.0, -60.0]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[92.0, -60.0], [172.0, -60.0], [172.0, -8.0], [92.0, -8.0], [92.0, -60.0]]]}", "state": "active", "temporal_coverage_from": "2019-04-08 01:55:29", "title": "Australia's Seabed Map 2023", "type": "dataset", "unpublished": false, "url": null, "version": null, "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-16T12:39:49.609443", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "Download the map (pdf) [80.1 MB]", "format": "PDF", "hash": "", "id": "5d39d62f-b3f0-4efa-87c7-7fd8c146f476", "last_modified": null, "metadata_modified": "2025-10-16T12:39:49.594293", "mimetype": null, "mimetype_inner": null, "name": "Download the map (pdf) [80.1 MB]", "package_id": "2b2f115a-2cd7-4e07-bae4-02d258f00b3c", "position": 0, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--link", "resource_type": null, "size": null, "state": "active", "url": "https://d28rz98at9flks.cloudfront.net/148890/148890_00_0.pdf", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "1 : 250, 000", "id": "b3b9ce29-0163-4ea4-99c1-b92c4c033cce", "name": "1 : 250, 000", "state": "active", "vocabulary_id": null}, {"display_name": "Bathymetry", "id": "ccab1927-2d7c-496d-8908-72285082f7e3", "name": "Bathymetry", "state": "active", "vocabulary_id": null}, {"display_name": "Depth", "id": "42031613-d149-469e-b449-3e9dbb3465b0", "name": "Depth", "state": "active", "vocabulary_id": null}, {"display_name": "EARTH SCIENCES", "id": "927af2a7-7457-45c2-bd55-10000fd09c14", "name": "EARTH SCIENCES", "state": "active", "vocabulary_id": null}, {"display_name": "ENVIRONMENTAL SCIENCE AND MANAGEMENT", "id": "25031166-8d21-4c0a-be85-55b0e695e781", "name": "ENVIRONMENTAL SCIENCE AND MANAGEMENT", "state": "active", "vocabulary_id": null}, {"display_name": "Earth Science | Oceans | Bathymetry/Seafloor Topography | Bathymetry", "id": "00ee54b3-dd82-4bdb-bb5b-15d831072153", "name": "Earth Science | Oceans | Bathymetry/Seafloor Topography | Bathymetry", "state": "active", "vocabulary_id": null}, {"display_name": "OCEANOGRAPHY", "id": "2ed27129-b4f4-4e72-9d4b-59099fcc3c34", "name": "OCEANOGRAPHY", "state": "active", "vocabulary_id": null}, {"display_name": "Published_External", "id": "5178775c-8044-4b7f-881f-5428a4e2d925", "name": "Published_External", "state": "active", "vocabulary_id": null}, {"display_name": "Seabed mapping", "id": "c9284d3f-e0ca-45ec-9fb9-eff8b4a74003", "name": "Seabed mapping", "state": "active", "vocabulary_id": null}, {"display_name": "Seafloor map", "id": "74f43c46-ca20-4dc1-9547-2815833ab0d2", "name": "Seafloor map", "state": "active", "vocabulary_id": null}, {"display_name": "Topography", "id": "ca3e0573-605f-48f5-81cb-254d63498d05", "name": "Topography", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": [], "extras": [{"key": "harvest_object_id", "value": "648de633-2940-462b-9710-3ed793287f1d"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}]}}
