We present an approach for estimating the fraction of text in a large corpus which is likely to be substantially modified or produced by language model (LLM). Our maximum likelihood leverages expert-written and AI-generated reference texts accurately efficiently examine real-world LLM-use at level. apply this case study scientific peer review AI conferences that took place after release ChatGPT: ICLR 2024, NeurIPS 2023, CoRL 2023 EMNLP 2023. results suggest between 6.5% 16.9% submitted as...
Submarine canyons influence oceanographic processes, sediment transport, productivity and benthic biodiversity from the continental shelf to slope beyond. However, not all perform same function. The relative of an individual canyon on these processes will, in part, be determined by its form, shape position margin. Here we present analysis geomorphic metrics using updated national dataset 713 submarine surrounding mainland Australia. These (attributes) for each are used classify them into...
Palaeoshorelines that lie submerged on stable continental shelves are relict coastal depositional and erosional structures formed during periods of lower sea level. An analysis the well-dated Late Quaternary (0–128 ka) sea-level record indicates most persistent (modal) levels were at 30 – 40 m below present, which occurred between 97 116 ka approximately 85 10 ka. A secondary modal position was 70–90 mostly a period fluctuating level 60 ka, as well around 87 (70 80 only) 12−15 For...
The Great Barrier Reef (GBR) World Heritage Area and adjacent Coral Sea Marine Park are under serious threat from global climate change. This study used sea surface temperature (SST) data to identify major marine heatwaves (MHWs) occurring in this region over the last three decades (1992–2022) map significant MHW events that have occurred between 2015 2022. We investigated mechanisms of MHWs identified potential coral refugia. increased frequency, intensity spatial extent. El Niño,...
Seabed sediment textural parameters such as mud, sand and gravel content can be useful surrogates for predicting patterns of benthic biodiversity. Multibeam sonar mapping provide near-complete spatial coverage high-resolution bathymetry backscatter data that are in parameters. acoustic collected across a ∼1000 km2 area the Carnarvon Shelf, Western Australia, were used predictive modelling approach to map eight seabed Four machine learning models modelling: boosted decision tree, random...
Northeastern Queensland is a far-field site from ice caps formed during the Last Glacial. However, region has experienced glacio-hydroisostatically driven coastal elevation change Holocene that generated distinctive relative sea-level record. We tested whether this subtle vertical movement of coast recorded in morphology and stratigraphy beach-ridge strandplain at Cowley Beach, which comprises series 36 prominent several subdued or truncated beach ridges. Previous studies have shown records...
During the past decade, personalized e-learning systems and adaptive educational hypermedia have attracted much attention from researchers in fields of computer science Aand education. The integration learning styles into an intelligent system is a possible solution to problems "learning deviation" "cognitive overload." In this study, we propose style prediction method based on pattern recognition technique. main contributions are: (1) it form middleware that can be applied other tutoring...
Coastal upwelling is important for marine ecosystems and the economy, because of its elevated primary secondary productivity large potential fish catch. This study developed a scale-independent semi-automatic image processing technique to map areas along 4500 km south-eastern coast Australia from 14-year monthly MODIS Sea Surface Temperature (SST) data. The results show that there significant spatial variability in mapped areas, month month, season year year. There also strong temporal...
Based on Himawari-8 Sea Surface Temperature (SST) data and the semi-automatic Topographic Position Index (TPI)-based mapping method, this study maps significant coastal upwelling in northern South China (NSCS). The results show that Minnan mainly occurs within 100 km off south coast of Fujian; Yuedong appears to east Pearl River Estuary, limited area shallower than 40 m; Qiongdong most frequently 75 m Hainan Island. results, paper quantitatively describes temporal spatial variations...
Multibeam bathymetric data provide critical information for the modeling of seabed geology and benthic biodiversity. The accuracy these models depends on data, which contain uncertainties that are stochastic at individual soundings but exhibit a distinct spatial distribution with increasing magnitude from nadir to outer beams. A restricted randomness method simulates both characteristics uncertainty performed better than complete in analyzing impact derived seafloor attributes.
Most models of forest type for predictive mapping cannot produce estimates confidence in the prediction individual pixels, even where they provide good overall accuracy. A new strategy that combines several based on different principles not only provides confidence, but also improves In this study, theoretical foundation Artificial Neural Networks, Decision Trees, and Dempster-Shafer’s Evidence Theory are briefly reviewed, compared, applied to a common data set. Two ways integrating results...
Perth Canyon is Australia's second largest submarine canyon, and its shelf-incising morphology contrasts with the more prolific slope-confined canyons that typify passive continental margin. The canyon has a sinuous course extends 120 km from shelf break (~180 m depth) to fan at foot of slope (~4500 m). Though initiates only 50 offshore major city, genesis geomorphic stability have not been well understood. Bathymetry data acquired in 2015 by Schmidt Ocean Institute enabled application new...

Abstract Sediment properties are known to influence acoustic backscatter intensity. This sediment‐acoustic relationship has been investigated previously through using physical geoacoustic models and empirical methods found be complex nonlinear. Here we employ a robust machine‐learning statistical model (random forest decision tree) investigate the most likely nonlinear sediment‐backscatter relationships. The analysis uses colocated sediment data (collected from 300‐kHz multibeam sonar...
