Coastal to deep-marine geomorphic classification: A standardised framework and review of terms to support globally consistent mapping

Marine and coastal geomorphology is inherently interdisciplinary, involving the interpretation of landforms shaped by overlapping hydrodynamic, sedimentary, tectonic, and biogenic processes across diverse physiographic regions. As the United Nations Decade of Ocean Science aims to provide robust scientific information to address ocean challenges, geomorphic data is becoming an increasingly critical baseline resource to support evidence-based decision-making. Standardised, inter-jurisdictional geomorphic frameworks enable consistent terminology across scales. Though marine sub-discipline lexicons are generally well established, seabed geomorphology mapping encompasses terminological nuances that can hinder analysts working across disciplinary boundaries.

To address these challenges, the International Seabed Geomorphology Mapping Working Group (ISGM) developed a marine and coastal classification framework using an Ocean Best Practice process that incorporates science-community input. This two-part approach separates morphological mapping (Part 1) from geomorphic interpretation (Part 2), constraining the uncertainty inherent to stratigraphic interpretation to a second step. In Part 1, 40 bathymetric shapes are mapped and classified using standardised Morphology Feature terms. In Part 2, a hierarchical framework and glossary of over 400 terms across 11 overlapping classes assigns geomorphic interpretation. The framework supports classification from Setting/Process through basic geomorphic units (BGU), types (BGU-T) and sub-types (BGU-sT), allowing users to tailor classification to available data quality and application needs.

Implementation of the ISGM scheme is supported by open-access, machine-readable digital vocabularies, which standardise established terms without redefining them, and GIS tools. Applied examples demonstrate utility across global datasets. By integrating existing terminology into a standardised, hierarchical framework, the ISGM approach provides the first cross-class geomorphic framework capable of supporting consistent terminology from global to local scales.

NESP MaC Project 4.4 - An Indigenous-led approach to advance the health and wellbeing of Tebrakunna Country and people of the Coastal Plains nation, north-eastern Tasmania (MTWAC)

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "An Indigenous-led approach to advance the health and wellbeing of Tebrakunna Country and people of the Coastal Plains nation, north-eastern Tasmania". No data outputs are planned for this project.

Tebrakunna Country in north-eastern Tasmania is a significant place for Tasmanian Aboriginal people and the Country of the Coastal Plains nation. Reconnecting to ancestral land and sea Country, restoring Aboriginal land management practices, and strengthening links between healthy Country and healthy people are central priorities for the Melaythenner Teeackana Warrana (Heart of Country) Aboriginal Corporation (MTWAC).

This Indigenous-led and co-designed project, delivered by MTWAC and the University of Tasmania across all four NESP Hubs, will support Healthy Country Planning for Tebrakunna. MTWAC Indigenous researchers, Tebrakunna Country rangers and community members, and western scientists will work together to identify priority values, targets, threats and viability of Tebrakunna land and sea Country.

The project will compile environmental, cultural and social information through MTWAC-led workshops and related research activities. It will develop approaches to assess the wellbeing benefits of connection to Country and on-Country activities, including spiritual, emotional, physical, socio-economic and environmental dimensions. It will also identify research, monitoring and capacity-building priorities, including opportunities in Sea Country condition assessment, cultural burning, cultural food sources, myerlee/golden kelp forest monitoring, seasonal cultural calendars, climate impacts and coastal wetland values.

Outputs will support MTWAC’s strategic priorities to manage culture and heritage, strengthen the Tebrakunna Ranger Program, build community capacity and employment pathways, and progress aspirations for a future Indigenous Protected Area over Tebrakunna land and sea Country. The project will provide a stronger knowledge base for monitoring and improving the health of Country and people through MTWAC-led governance and planning.

A multidisciplinary study of the Tasman Fracture Marine Park pelagic ecosystem

The Tasman Fracture Marine Park (TFMP), located off the southwestern coast of Tasmania, is an ecologically and culturally significant area characterised by dynamic and diverse marine ecosystems ranging from abyssal plains to rocky reefs. This region is a productivity hotspot due to the convergence of ocean currents and upwelling processes (Ridgway and Ling, 2023), which supports rich biodiversity, including endangered species such as the shy albatross (Thalassarche cauta), the migratory short-tailed shearwater (Ardenna tenuirostris), the endemic Australian fur seal (Arctocephalus pusillus doriferus) and expanding populations of long-nosed fur seal (Arctocephalus forsteri).

The primary objectives of this multidisciplinary research were to quantify the physical water properties within the TFMP to establish baseline environmental conditions; map mesopelagic (midwater) productivity using acoustic equipment; characterise the foraging behaviour and habitat use of key marine predators through biotelemetry devices; investigate the diet of seabird and fur seal species to understand pelagic food web interactions; and assess cetacean species diversity, temporal patterns, and quantify underwater noise using passive acoustic monitoring.

To achieve these objectives, the study employed a combination of methodologies (see 'Lineage' section for full methodology):
• Oceanographic analysis provided insights into the climatology and productivity patterns influenced by the East Australian Current and the Zeehan Current.
• Biotelemetry tracking of seabirds and seals provided data on foraging behaviour and habitat use of key predators.
• Scat sampling of predator species combined with DNA metabarcoding techniques were utilised to identify prey species and provide detailed dietary profiles.
• Underwater acoustic recorders were used to monitor cetacean vocalisations and assess underwater noise levels.

In summary, this research provides essential baseline data and insights into the complex interactions within the TFMP's ecosystems. The findings emphasise the need for integrated, multidisciplinary approaches to marine conservation. By addressing the identified challenges and implementing the recommendations, managers can enhance the resilience of the TFMP, ensuring the protection of its unique biodiversity in the face of environmental changes.

Preliminary post-cruise report : hydrocarbon gas geochemistry in sediments of the offshore Otway and Gippsland Basin: Project 9131.20 BMR Fossil Fuels Project

During April/May 1988, the BMR research vessel 'Rig Seismic' carried out a 21 day geochemical and sedimentological research program in the Otway (17 days) and Gippsland (4 days) Basins. Light hydrocarbon gases (C1-C6) were measured in sediments at 342 locations on thecontinental shelf and upper continental slope. Thermogenic hydrocarbons were identified in near-surface sediments at forty-two locations in the Otway (32) and Gippsland (10) Basins. The major results from the Otway Basin include:
<ol>
<li>

Evidence of thermogenic hydrocarbon sediments was found at seven locations on the Crayfish Platform, seven locations on the Mussel Platform and eighteen locations in the VolutaTrough.
</li>
<li>

Wet gas contents ([C2-C4/C1-C4] x 100), which provide some indication of both hydrocarbon source type and maturity,are highest on the basin margins, i.e. the Crayfish and Mussel Platforms. Wet gas contents were consistently lower in the Voluta Trough.
</li>
<li>

Total C1-C4 gas concentrations were higher in the Voluta Trough than on the basin margins, probably because of more intense near-surface faulting in the trough.
</li>
<li>

The geochemical data, when integrated with thermal maturation modelling and well data, suggest that the principal liquidhydrocarbon source rocks are located at the base of the Early Cretaceous Otway Group (i.e. basal Pretty Hill Sandstone). The Late Cretaceous Sherbrook Group appears to be gas-prone.
</li>
</ol>

Preliminary data from the Gippsland Basin identify ten locations which show evidence of thermogenic hydrocarbons in near-surface sediments.

Polychaetes (Annelida) of the Oceanic Shoals region, northern Australia: considering small macrofauna in marine management

Northern Australia has been the focus of recent marine biodiversity research to support natural resource management for both industry and conservation, including management of the Oceanic Shoals Australian Marine Park (AMP). Much of this research has targeted habitat-forming sessile invertebrates and charismatic megafauna, but smaller macrofauna and infauna may also be important because of their  roles in ecosystem functions. In this study we characterised the biodiversity of polychaetes collected from four marine surveys to the Oceanic Shoals AMP between 2009 and 2012 from which sediment samples were elutriated (500 μm) to separate macrofauna. We used this species-level inventory to examine several questions related to marine management, namely: (1) do polychaete assemblages vary among surveys; (2) can environmental variables or geomorphology explain differences in community structure; and (3) how do ecological patterns change according to taxonomic resolution (species, family) and functional group (feeding, habitat, mobility)? A total of 2561 individual polychaetes were collected from 266 samples, representing 368 species and 43 families, including new species and genera, as well as new family records for Australia (Iospilidae, Lacydoniidae). Polychaete species assemblages and functional groups showed variation among the surveys, but this was not observed at the family level. Species and family assemblages were weakly related to environmental factors, but functional groups showed stronger relationships. Plains and banks each supported distinct polychaete assemblages, although the latter showed temporal variation. The results provide baseline biodiversity and ecological data about polychaetes on the northern Australian shelf, and these are discussed in relation to marine management strategies. Notably, intersurvey and environmental patterns differ from those of larger sessile fauna (sponges) collected on the same surveys, highlighting the need to consider small macrofauna in monitoring programs of marine protected areas.

The dataset comprises 10179 individuals from 146 species of fishes, sharks, rays and sea snakes observed at around Southern Great Barrier Reef Marine Park Seabed Project Cruise 3 using 140 baited remote underwater video stations (BRUVS(TM)). 1217 images were captured from these cameras.

Approximately 3500 of the best images from all BRUVS (TM) projects are stored in a reference library.

Data recorded concern:
- classification of the habitat in the field of view (topography, sediments, benthos)
- the identity of fish and CAABCODES
- their time of arrival
- their behaviour (8 categories, including feeding on the bait)
- their maturity (adult or juvenile)
- their relative abundance (as MaxN = the maximum number visible at one time, or distinguishable at different times as separate individuals e.g. much larger/smaller, male/female)
- the time elapsed before MaxN and feeding occurs.

A custom interface has been developed by AIMS staff, using Microsoft Access, for reading and analysis of BRUVS(TM) tapes.

Seabed glacial geomorphology features on the East Antarctic continental shelf: first results from RV Polarstern expedition PS141, EASI-3

The recent RV <em>Polarstern</em> Expedition PS141 <em>"East Antarctic Ice Sheet Instability and its interaction with changes in Southern Ocean circulation - Part 3”</em> (EASI-3; 6 Feb to 14 April 2024) aimed to investigate past ocean-ice sheet interactions along the East Antarctic margin over different geological timescales. East Antarctic Ice Sheet fluctuations directly impact global sea level and ocean circulation through the interplay between oceanic processes and seabed topography, especially offshore of the vulnerable Aurora subglacial basin and Shackleton Ice Shelf.

More than 10,000 nautical miles of new hydroacoustic data (continuous multibeam and sub-bottom profiles) were collected from parts of the Davis and Mawson Seas, in a target area off the ice margin between Wilhelm II to Wilkes Land (between 85° E and 115° E). We present some preliminary bathymetric and geomorphic mapping results that reveal a variety of submerged glacial features on the continental shelf, including iceberg scours, mega-scale glacial lineations, subglacial basins, and grounding zone wedges. Further detailed mapping and interpretation of these features will help extend the record of past glacier and ice sheet changes in East Antarctica and inform contemporary models and future projections.

Wessel Marine Park Post-Survey Report for IN2019T02

In October 2019, opportunistic mapping and imagery of the Wessel Marine Park on the RV Investigator revealed a localised band of high biodiversity linked to a unique and culturally important geomorphological feature in the otherwise uniform seascape prevalent in the Wessel Marine Park. Our findings help contribute to an understanding of the values of a northern marine park, including an inventory of communities and habitats as well as potential relationships to geomorphic features and culturally important sites. This has national significance to the implementation of the northern marine park management plan, as well as informing future monitoring programs in northern Australia.
