Voyage IN2019_V04 contributed an additional 29,000 kms2 of seafloor survey data to the Coral Sea knowledge base. From this new bathymetric data individual seamounts have been extracted and have been classified to the Geoscience Australia Geomorphology Classification Scheme. This dataset contains two layers representing the classification layers- 1) Surface (Plain, Slope, Escarpment) and 2) fine scale Geomorphology of the seamount for the Cassowary Seamount. Ongoing research with this survey data will provide new insights into the detailed geomorphic shape and spatial relationships between adjacent seabed features. This information will be released in future publications to show the potential of how the scale of such seafloor data can be used for predictive habitat modelling when analysed with the biological data overlays.

[This data has been superseded by a synthesised global dataset which includes additional ecological data contributed by non-RLS entities (National Reef Monitoring Network). Please visit the corresponding NRMN Collection (IMOS - National Reef Monitoring Network Sub-Facility - Survey metadata) for the most current version of this data. See "Downloads and Links" section below.] This dataset shows the location of Reef Life Survey (RLS) sites surveyed by divers along 50m transects on shallow rocky and coral reefs, worldwide. Although surveys are undertaken as part of monitoring programs at particular locations (mostly in Australia), this dataset contains only spatial information, with repeat surveys of sites not included. Biological data (abundance of invertebrates and fish, habitat quadrats) collected from these surveys is available as separate datasets through the AODN Data Portal (https://portal.aodn.org.au/ - search for 'NRMN')

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A7 - "Monitoring population dynamics of ‘Western’ Right Whales off Southern Australia". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Continuation (since 1993) of annual aerial surveys, to include counts and identification photographs, of Southern Right Whales between Cape Leeuwin (WA) and Ceduna (SA), where wintering animals come close to the coast – adult females to calve, at approximately three-year intervals, other adults and juveniles less regularly. The area is the main wintering ground of a major ‘western’ subpopulation of ‘Australian’ right whales, differing in number and extent of recovery (from 19th century hunting) from an ‘eastern’ subpopulation which so far shows little if any recovery. Counts allow estimation of population trend and current numbers; identification photographs allow estimation of life history parameters. This project serves to implement a very high priority action in the Australian Government’s Conservation Management Plan for Southern Right Whale (2011-21) – Action Area B1: Measuring and monitoring population recovery; continue to obtain and refine population abundance and trends for the south-west population. Planned Outputs • Counts of animals (by class – cows accompanied by calves, other animals, by position (GPS) and time. • Head and (where appropriate) body photographs, by position and time. • Information on Biologically Important Areas for Southern Right Whales in the area surveyed. • ‘Progress’ and ‘Final’ reports, annually • Report annually to the Scientific Committee of the International Whaling Commission. • Public information through press releases and on the Museum website.

This record describes the towed video component from the from the Marine National Facility (MNF) RV Investigator research voyage IN2019_T02, titled "Deep seascapes of the Great Barrier Reef: Uncovering submarine canyons and landslides." The voyage took place between October 4 and October 14, 2019 departing from Brisbane (QLD) and arriving in Darwin (NT). Four 1500 m video transects were undertaken across a range of geomorphic features and depth gradients, on October 11, 2019.
