This dataset represents the current extent of bathymetry datasets held by AusSeabed. This dataset is live and will continue to be augmented as coverage is supplied from respective AusSeabed partners. Surveys have been conducted by a wide range of organisations and countries, both inside and outside of Australia's EEZ and for various purposes. Each polygon contains metadata describing the nature of data collection, including details of the survey, as well as the principle investigator of the project. Not all surveys are currently available for download; if available, the Data Access URL attribute will indicate how to access the survey data. Polygons are based on a 500m gridding of the survey data, so may not be representative of the true survey extent when viewed at large scale.

For more information, please visit the AusSeabed Marine Data Discovery portal.

This dataset represents the current extent of bathymetry compilation products delivered by Geoscience Australia. Compilation products have been generated from numerous data sources including survey data, lidar, interpolation and other depth data. Each polygon shows the extent of the compilation dataset, and attributes contain information regarding data sources, product details and access methods. Contributing individual survey data can be found in the AusSeabed Bathymetry Holdings dataset. Dataset link

The WMS layer shows the coverage of processed multibeam data, which was acquired and processed by the Alfred Wegener Institute for Polar and Marine Research (AWI) Bathymetry group. This layer is live and will continue to be augmented as datasets are supplied by AWI. Simplified polygons were generated from the processed point data using open source tools (for details see the standard operating procedure (SOP) link in the metadata information). To give a complete overview where AWI collected data, datasets under moratorium are included together with unrestricted datasets and datasets with a public copyright license (e.g. Creative Commons). Please note, that datasets under moratorium are not available for download yet. Please check the metadata information of the features for detailed information.

Published multibeam bathymetry raw data archived at PANGAEA are visualized and footprints (polygon) calculated by using the software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2021) and gdal (GDAL/OGR contributors (2021).

The grids as a base for footprint extraction are created by using a Gaussian weighted mean filter during processing. Grid resolution calculation is based in general on average depth for the entire dataset, however may also depend on limited processing capacities. Thus, raster resolution and therefore footprints may not be representing the true coverage of the data. In addition, please note that occasionally in case of very bad data quality some data files of the corresponding dataset may have been left out for grid (footprint) calculation for this layer.

This index enables you to identify the freely available bathymetric data held and used by Land Information New Zealand (LINZ) on its New Zealand coastal nautical charts. Third-party data is also included. Some of the data holdings date back to the 1930s. The polygons comprising the index show the extent of the survey datasets. The attributes attached to each polygon will enable you to view, amongst other attributes, the age and quality of the bathymetric data.

The bathymetric data is not downloadable from the LINZ Data Service. Datasets prior to the year 2000 are predominantly available only as georeferenced TIFF images of the original hard copy sounding sheets. Data post-2000 is often available as both georeferenced TIFF images and as digital data files (vector data in plain text format).

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset.

• NZ Bathymetric Data Index
• SW Pacific Bathymetric Data Index
• Antarctic Bathymetric Data Index
• NZ Bathymetric Data Index (Third-Party)

This index enables you to identify freely available digital bathymetric surface models owned by Land Information New Zealand (LINZ), as well as models that contain third-party data. This data provides a 3-dimensional model of the surface of the seafloor. These surface models have been created by LINZ from publically funded single- or multi-beam data collected in the New Zealand coastal area since early 1998. The polygons in the index show the extent of these gridded data models, and include descriptive information, such as the age and quality of the data.

The gridded surface models are not downloadable from the LINZ Data Service, but can be provided to you on request.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset, and formats in which the data is available.
