ABSTRACT Stratigraphic models typically predict accumulation of deep-water sands where coeval shelf-edge deltas are developed in reduced-accommodation and/or high-sediment-supply settings. On seismic data, these relationships commonly investigated on a small number clinothems, with limited control their lateral variability. Advanced full-volume interpretation methods now offer the opportunity to identify high-order (i.e., 4th 5th) sequences clinothems) and evaluate controls shelf-to-basin...
Following decades of technological innovation, geologists now have access to extensive 3D seismic surveys across sedimentary basins. Using these voluminous data sets better understand subsurface complexity relies on developing stratigraphic workflows that allow very high-resolution interpretation within a cost-effective timeframe. We developed an innovative workflow combines full-volume and semi-automated horizon tracking with analysis. The consists converting from (two-way traveltime)...
Palaeoshorelines and associated palaeo-coastal features are studied to reconstruct past sea level, climate, depositional environments. Their identification typically depends on direct field observations is therefore challenging in the marine environment, where interpretation mostly relies sparse geophysical data. This review presents, based 118 published case studies, a summary of morphological evidence that can be used identify submerged relict coastal worldwide, using only Four feature...
Abstract. High-resolution bathymetry forms critical datasets for marine geoscientists. It can be used to characterize the seafloor and its habitats, understand past sedimentary records, even support development of offshore engineering projects. Most methods acquire data are costly only practically deployed in relatively small areas. is therefore develop cost-effective advanced techniques produce regional-scale datasets. This paper presents an integrated workflow that builds on satellites...
Bedforms are key components of Earth surfaces and yet their evaluation typically relies on manual measurements that challenging to reproduce. Several methods exist automate identification calculate metrics, but they often exhibit limitations where applied at large scales. This paper presents an innovative workflow for identifying measuring individual depositional bedforms. The the local minima maxima grouped by neighbourhood analysis calibrated using curvature. method was trialed a synthetic...
This article presents a national seismic-derived bathymetric compilation based on the integration of 253 3D seismic surveys. Individual surveys were combined to produce four regional compilations covering an area 267,000 km2, with spatial resolution 30 × m and vertical accuracy 5 + 5%d. The production dataset is survey first returns vessel echosounder measurements. Following extraction depth soundings, all data points converted from time using synthetic velocity profiles filtered remove...
Halimeda, calcareous green algae, bioherms are among the largest inter-reef biogenic structures in Great Barrier Reef, spanning over >6000 km2 of continental shelf – an area exceeding adjacent coral reefs at equivalent latitudes1. Previous studies have shown peculiar circular to reticulate shapes, internal structure and volume these accumulations, underscoring their significant contribution global neritic carbonate factory throughout Holocene2,3. However, a comprehensive...
Carbonate margins are records of the palaeoclimatology, palaeoceanography and palaeogeography continental shelves, their study can help identify both regional global palaeoenvironmental changes.

Abstract Onshore and offshore site investigations along the dryland tide-dominated De Grey River delta (northwestern Australia) led to unexpected discovery of largest yet-known marine ooid shoals in Indo-Pacific region. Ooids exhibit up 60 tangential aragonitic laminae that were formed around fluvial sediment grains during late Holocene. Covering an area >1250 km2, their spatial extent rivals size individual from Bahamas. Shoals appear be spatially linked with River, suggesting...
The Early Cretaceous palynological successions record one of the earliest waves angiosperm radiation in several low-latitude localities, including Arabian Plate. analysis 59 core and cuttings samples from late Barremian–early Aptian Biyadh Shu'aiba formations, offshore Saudi Arabia, reveals remarkably high diversity. These angiosperms inhabited northeastern Gondwana together with a diverse flora that also included bryophytes, lycopodiopsids, ferns, conifers, other gymnosperms. A review...
Understanding the stratigraphic architecture of shelf-margin clinoforms is key to determining how sediments are transferred deep-water settings and interplay tectonics (subsidence/uplift), eustasy variations in sediment supply rates calibre, impacts sand delivery. Here, clinothems used establish quantitative relationships between shelf-to-basin transfer. In Bight Basin on southern margin Australia, Hammerhead shelf prograded during Late Cretaceous, following continental break-up from...
Understanding the primary drivers of lateral and vertical variability in stratal architecture shelf-margin settings is key to understanding how sediments are partitioned from shelf slope basin floor source-to-sink systems. In this study, we model 4-D evolution a margin over period 18.5 m.y. using Badlands stratigraphic forward modeling software. The modeled system analogous Hammerhead developed Bight Basin (southern Australian margin) during Late Cretaceous, with forcing parameters...
The Western Australian margin is a unique coral reef province, with modern development occurring at latitudes as far south 29°S. genesis of this province may go back to the Oligo-Miocene, since geological features ~30 million-year-old and younger interpreted reefs are known from offshore seismic surveys. nature these is, however, uncertain, they only sparsely sampled, time-equivalent outcrops present in few remote understudied locations. This study investigates middle Miocene shallow-water...
The Rowley Shelf, the southern half of tropical, carbonate-dominated, North West Shelf Australia, is covered with linear ridges that can be tracked parallel to coast over 1100 km between modern and 140 m isobath. Here, we investigate origin nature these based on integration extensive borehole data, high-resolution geophysical age dating compaction analysis. Our investigation reveals each ridge consists now-submerged relict coastal deposits were formed last 200,000 years through wave, tidal,...
Abstract Recognition of seismic unconformities is crucial for interpreting basin history from reflection data sets in both siliciclastic and carbonate settings. While it well established that non-erosional changes sedimentary facies can create reflections mimic (i.e., pseudo-unconformities), these features are generally considered to be localized uncommon, and, therefore, largely overlooked during interpretation. Diagenetic alteration strata also affect the morphology reflectors mislead...
