The datasets contain summaries of Victorian logbook data on catch and effort distribution for commercial fisheries in state marine and estuarine waters. The logbook data has been recorded and submitted to Victorian Fisheries Authourity by commercial fishers. The data are aggregated to produce summaries of total catch and effort by fishery at a reporting blocks where 5 boats or more operate. For areas where less than 5 boats operate the data is shown as confidential. The data was mapped using 5 year - financial year periods; 2003/04 to 2007/08, 2008/09 to 2012/13, 2018/19 to 2022/23, and 1 year; 2022/23.

This dataset is a compilation product of all publicly available surveyed bathymetry within the Australian Marine Parks (AMPs, 2025 boundaries), merged into a single multi-resolution composite per AMP. The data was compiled by Seamap Australia as part of an Our Marine Parks (Parks Australia) project with funding from the Australian Government to improve knowledge relating to classification of the Australian Marine Parks real estate. This compilation of bathymetry data was the first step in generating geomorphometry classifications (see https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/40e9283b-d4ed-4176-8fe6-112b8697003f for derived geomorphometry maps). Bathymetry data was collated from AusSeabed data holdings (https://portal.ga.gov.au/persona/marine), the WA Bathymetry Portal (https://dot-wa.maps.arcgis.com/apps/webappviewer/index.html?id=d58dd77d85654783b5fc8c775953c69b), the Australian Ocean Data Network (https://portal.aodn.org.au/) and other existing public data repositories. A single multi-resolution bathymetry mosaic, and associated multi-resolution hillshade mosaic, was generated for each AMP. Data is supplied as a single Web Map Service of bathymetry on hillshade for the mapped regions. Data is available for download as (1) bathymetry, and (2) hillshade, Cloud-Optimised GeoTIFF (COG) files for each AMP. The table below indicates the Parks included in this data package, and the percent coverage of bathymetric data for each. Parks not expressly listed below had no publicly accessible bathymetry data available from the sources listed in the 'lineage' section below. This dataset was last updated on 28/07/2026 and represents all public bathymetry data intersecting AMPs that could be located as of that date.

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2023 project "Monitoring, aggregation areas and approaches to improve data effectiveness for southern right whale conservation". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Southern right whales are listed as Endangered under the EPBC Act and are recovering slowly from historical whaling. In Australia, recovery differs between the growing western population and the more poorly understood eastern population, where available data are largely opportunistic. Improved abundance estimates, photo-identification workflows, aggregation-area assessment, and understanding of connectivity are needed to support conservation management. This project delivered priority information for southern right whale conservation through four linked components: (1) long-term aerial surveys of the western population; (2) expansion and integration of photo-identification datasets within the Australian Right Whale Photo-Identification Catalogue (ARWPIC); (3) development of statistical approaches to combine opportunistic and systematic observations; and (4) collection of movement and genomic data to assess connectivity between eastern and western subpopulations. The project continued annual aerial surveys from Perth to Ceduna to update abundance trends and reproductive parameters for the western population. Photo-identification images and metadata were collated from archived, targeted, and opportunistic sources across eastern and western aggregation areas, supporting matching of individual whales, assessment of reproductive areas, and estimation of population parameters. The project also developed methods to expand the use of opportunistic sightings data alongside systematically collected observations, improving capacity to estimate population size, trends, recovery rates, residency, site fidelity, and connectivity. Movement, photo-identification, and genomic data collected near the boundary of the eastern and western subpopulations, particularly around Encounter Bay and adjacent waters, supported assessment of population structure, whale movements, habitat use, and potential exposure to human activities. The outputs of this project support updates to the national Southern Right Whale Conservation Management Plan, Biologically Important Area (BIA) mapping, marine park management, and risk assessments for marine industries and tourism. Consultation and engagement with Indigenous groups in South Australia and Western Australia enabled communication of research goals and findings, supported knowledge sharing, and identified opportunities for collaboration and capacity building linked to southern right whale conservation. Outputs • Individual whale photo-identifications in aggregation areas [ARWPIC image catalogue] • Aerial survey data for 2023, 2024, 2026 [dataset] • Exposure to single and cumulative threats [dataset] • Whale tracking tracking, behaviour, and dive data [dataset] • Final project report [written]

Data from multibeam echosounder surveys taken as part of the Ningaloo Outlook project were classified into various seafloor cover types according to their hardness, rugosity and depth. The classifications were validated with towed video ground truth where it was available. This dataset describes two AOIs which are explicitly part of the Ningaloo Outlook Deep Reefs project. Substratum classifications were applied using multibeam backscatter angular response curves along with rugosity as input to a maximum likelihood classifier. See original metadata record(s) and associated attached documents for accuracy estimates, alternate classification techniques, and additional surveyed areas. https://doi.org/10.25919/kssa-5b46 https://doi.org/10.25919/kttc-x397 https://doi.org/10.25919/8m65-7k26

This dataset contains polygon extents of all known bathymetry surveys and bathymetry compilations in Australia's marine jurisdiction, including the Australian Antarctic Territory. Each polygon includes metadata identifying attributes, contact details, information on the public availability of data, and (in the case of published data) gridded resolution. The following data sources have been used as inputs: • AusSeabed 'Bathymetry Acquisitions Coverage (Dynamic)' (https://dx.doi.org/10.26186/148613) • AusSeabed 'Bathymetry Compilations Coverage (Dynamic)' (https://dx.doi.org/10.26186/148614) • computed footprints (suffixed by _L0_Coverage) of bathymetry data published through AusSeabed Warehouse Geoserver (https://warehouse.ausseabed.gov.au/geoserver) • computed footprints (suffixed by _BBOX) of bathymetry data published through CSIRO Geoserver (https://www.cmar.csiro.au/geoserver) • manually computed footprints of bathymetry data published through other online repositories: WA Bathymetry Portal (https://dot-wa.maps.arcgis.com/apps/webappviewer/index.html?id=d58dd77d85654783b5fc8c775953c69b), the Australian Ocean Data Network (https://portal.aodn.org.au) and the NSW SEED Portal (https://www.seed.nsw.gov.au) This dataset was generated to enable reporting for Seamap Australia's 'State of Knowledge' functionality (https://seamapaustralia.org/map/), as existing coverage information does not contain metadata on gridding resolution. The dataset is live and will be continually updated as new surveys are conducted and new coverage information becomes available. Gridding resolution will be appended to existing survey extents when historical surveys are published. This dataset is updated regularly (date of last update: 23/07/2026) and will be maintained in perpetuity until such time that the information required for Seamap Australia's 'State of Knowledge' functionality is delivered through an alternative mechanism. Note that a degree of spatial simplification has been conducted to reduce filesize and polygon complexity. All efforts have been made to maintain true survey extent (area-preserving simplification has been used), but polygons may not be representative of the true survey extents, particularly in the case of reported extents from unpublished surveys which cannot be verified.
