The palaeogeography of the Bass Strait land-bridge, a vital zone of human and biological connectivity across southeastern Australia

David M. Kennedy, Ali Jalali, Bruno David, Matthew C. McDowell et autres

Land-bridges are key regions of human connectivity, yet how geography affected peoples' movement during flooding is poorly understood. Bass Strait is one of the most important land-bridges in Australasia, separating Lutruwita/Tasmania from the mainland of Australia. The land-bridge forms a key part …

A continental review of Australia's Cenozoic megafans and associated large accretionary fluvial systems

Gerald C. Nanson, Rachel A. Nanson

Australia is the world's lowest and flattest continent with the most negative water balance. Gentle Cenozoic tectonism has formed numerous moderately depressed basins, mostly on the eastern half of the continent that have accumulated substantial alluvium in diverse climatic zones. While many …

Rule-based semi-automated tools for mapping seabed morphology from bathymetry data

Zhi Xing Huang, Rachel A. Nanson, Mardi A. McNeil, Michal Wenderlich et autres

Seabed morphology maps and data are critical for knowledge-building and best practice management of marine environments. To facilitate objective and repeatable production of these maps, we have developed a number of semi-automated, rule-based GIS tools (Geoscience Australia’s Semi-automated Morphological Mapping Tools - …

The Holocene Mitchell Megafan, Gulf of Carpentaria, Australia

Tessa I. Lane, Rachel A. Nanson, R. Bruce Ainsworth, Boyan K. Vakarelov

As the world’s lowest and flattest continent, Australia exhibits numerous gently inclined topographic basins that have generated a large number of megafans. One of the most extensive contiguous arrays occurs on the western flank of Cape York Peninsula. These megafans are derived …

A two-part seabed geomorphology classification scheme; Part 2: Geomorphology classification framework and glossary (Version 1.0)

Rachel A. Nanson, Riccardo Arosio, Joana Gafeira, Mardi A. McNeil et autres

Maps of seabed geomorphology derived from bathymetry data provide foundational information that is used to support the sustainable use of the marine environment across a range of activities that contribute to the Blue Economy. The global recognition of the value of the …

Wetlands Insight Tool: Characterising the Surface Water and Vegetation Cover Dynamics of Individual Wetlands Using Multidecadal Landsat Satellite Data

Bex Dunn, Emma Ai, Matthew J. Alger, Benjamin G. Fanson et autres

Abstract Wetlands around the world provide crucial ecosystem services and are under increasing pressure from multiple sources including climate change, changing flow and flooding regimes, and encroaching human populations. The Landsat satellite imagery archive provides a unique observational record of how wetlands …

A two-part seabed geomorphology classification scheme: Part 2 – a geomorphic classification framework and glossary

Rachel A. Nanson, Riccardo Arosio, Joana Gafeira, Mardi A. McNeil et autres

Maps of seabed geomorphology provide foundational information for a broad range of marine applications. To be most effective, geomorphic characterisation of the seabed requires standardised, multi-scalar and interjurisdictional approaches that can be applied locally, regionally and internationally using the best available data. …

Use of Remote-Sensing to Quantify the Distribution of Progradation/erosion Along a Forced-Regressive Modern Coastline: Driving Factors and Impact on the Stratigraphic Record

Valentin Zuchuat, Miquel Poyatos‐Moré, Björn Nyberg, Rachel A. Nanson et autres

The long-term development of ancient and modern coastal distributive fluvial systems (DFSs) during periods of relative sea-level highstand or fall usually drives net-progradation of shorelines. Such systems often develop in periods of relative sea-level highstand or fall and typically record annual to …

Submarine canyons and slides in the central-west Otway Basin: their morphology, genesis, links to groundwater discharge and tsunamigenic potential

Patrick De Deckker, Rachel A. Nanson

The morphology and development of several submarine canyons offshore southeast South Australia and western Victoria are described. The existence of three of those canyons had been foreshadowed in 1963 by N. Boutakoff, who thought them to be linked to ancient courses of …

Cretaceous to Cenozoic controls on the genesis of the shelf-incising Perth Canyon; insights from a two-part geomorphology mapping approach

Rachel A. Nanson, Irina Borissova, Zhi Xing Huang, Alexandra L. Post et autres

Perth Canyon is Australia's second largest submarine canyon, and its shelf-incising morphology contrasts with the more prolific slope-confined canyons that typify Australia's passive continental margin. The canyon has a sinuous course that extends 120 km from the shelf break (~180 m depth) …

Geomorphic insights into Australia's coastal change using a national dataset derived from the multi-decadal Landsat archive

Rachel A. Nanson, Robbi Bishop‐Taylor, Stephen Sagar, Leo Lymburner

Australia has a vast, diverse and dynamic shoreline, and national perspectives on the mechanisms, magnitude and trajectories of coastal adjustment are required to underpin informed management. Geoscience Australia's national Digital Earth Australia Coastlines (DEA Coastlines) was developed to help address this need. …
