Automatic Mapping and Characterisation of Linear Depositional Bedforms: Theory and Application Using Bathymetry from the North West Shelf of Australia
Lebrec, Ulysse; Riera, Rosine; Paumard, Victorien; O'Leary, Michael J.; Lang, Simon C. (Peer reviewed; Journal article, 2022) -
Differentiating reefal ridges from relict coastal ridges: Lessons from the seismic geomorphologic study of buried Miocene buildups (North West Shelf, Australia)
Riera, Rosine; Lebrec, Ulysse; Lang, Simon C.; Paumard, Victorien (Peer reviewed; Journal article, 2023)Linear buildups formed in tropical carbonate environments are often interpreted as bioconstructed reefs. Nevertheless, coastal processes can also form extensive sedimentary ridges exhibiting buildup morphologies. This study ... -
Discovery of Holocene ooid shoals in a siliciclastic delta, De Grey River, North West Shelf, Australia
Lebrec, Ulysse; Lang, Simon C.; Paumard, Victorien; O'leary, Michael J.; Yokoyama, Yusuke; Hacker, Jorg; Webster, Jody (Peer reviewed; Journal article, 2023)Onshore and offshore site investigations along the dryland tide-dominated De Grey River delta (northwestern Australia) led to the unexpected discovery of the largest yet-known marine ooid shoals in the Indo-Pacific region. ... -
Drilling 1100-km-long seafloor ridges reveals how palaeoshorelines control carbonate shelf morphologies (North West Shelf, Australia)
Lebrec, Ulysse; Riera, Rosine; O´Leary, Michael; Webster, Jody M.; Yokoyama, Yusuke; Gliganic, Luke A.; Lang, Simon C.; Paumard, Victorien (Peer reviewed; Journal article, 2023)The Rowley Shelf, the southern half of the tropical, carbonate-dominated, North West Shelf of Australia, is covered with linear ridges that can be tracked parallel to the coast over 1100 km between the modern coast and the ... -
Evolution of the Exmouth-Barrow carbonate margin through the Miocene: Insights from 3D seismic data and field investigations (North West Shelf, Australia)
Riera, Rosine; Paumard, Victorien; Bourget, Julien; Allan, Tony; Lebrec, Ulysse (Peer reviewed; Journal article, 2023)Carbonate margins are records of the palaeoclimatology, palaeoceanography and palaeogeography of continental shelves, and their study can help identify both regional and global palaeoenvironmental changes. This study ... -
Recreational Fishing Impacts in an Offshore and Deep-Water Marine Park: Examining Patterns in Fished Species Using Hybrid Frequentist Model Selection and Bayesian Inference
Aston, Charlotte; Langlois, Tim; Fisher, Rebecca; Monk, Jacquomo; Gibbons, Brooke; Giraldo-Ospina, Anita; Lawrence, Emma; Keesing, John; Lebrec, Ulysse; Babcock, Russ C. (Peer reviewed; Journal article, 2022)No-take marine reserves are often located in remote locations far away from human activity, limiting perceived impact on extractive users but also reducing their use for investigating impacts of fishing. This study aimed ... -
Towards a regional high-resolution bathymetry of the North West Shelf of Australia based on Sentinel-2 satellite images, 3D seismic surveys, and historical datasets
Lebrec, Ulysse; Paumard, Victorien; O'Leary, Michael J.; Lang, Simon C. (Peer reviewed; Journal article, 2021)
