Despite its importance, reconstruction of past hydroclimate in the Kimberley has been challenged by its semi-arid environment, which limits archive preservation, and by its remoteness. In recent years, however, a growing body of work has demonstrated the potential of a diverse range of atypical archives for reconstructing Kimberley hydroclimate. Here we present the current state of understanding of the hydroclimate of the Kimberley, drawing on environmental reconstructions spanning the last 65,000 years. Our synopsis is that the Kimberley experienced a drier climate during the last glacial compared with the Holocene, although there remains much discrepancy between records, particularly those from early Marine Isotope Stage 3, when precipitation levels higher than present are indicated by some records. Records suggest that either dry conditions or high variability marked the MIS 2/1 transition before a wet early Holocene, leading into increased hydroclimate variability in the mid-late Holocene. There remains a sparsity of records for this vast region. The obtainment of long, high temporal resolution records is required to resolve discrepancies between existing records, and to shed light on possible causes of local scale palaeoclimate variability and extremes.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"22 ","pages":"Article 100327"},"PeriodicalIF":2.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148177823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a regional palaeoenvironmental interpretation remains challenging as established geochronological frameworks are based on a limited number of sites where fan aggradation was constrained by numerical dating. Consequently, it is unclear to what extent fan aggradation and progradation is controlled by large-scale allogenic versus individual autogenic forcing. To therefore expand the regional alluvial fan morphochronology along the south-central coast, the applicability of cost-effective Schmidt hammer exposure dating (SHD) was explored on boulders of plutonic lithology. The independently exposure-dated coastal alluvial fan (CAF) Paposo served as regional age-calibration site for SHD of 11 telescopic CAFs between 24.25°S and 25.25°S. SHD was complemented by the assessment of the CAFs’ terrestrial and shelf morphometry and the hydromorphometric and climatic catchment properties. The results of the successfully calibrated SHD suggest that weathering in the coastal desert allows for age ranges extending over the Late Quaternary. The expanded morphochronology reveals a distinct fan evolution segmenting a synchronous morphogenesis south of 24.85°S from a diachronous one in the north. Spatial segmentation is reflected in specific catchment hydromorphometric characteristics and differences in the relationships between terrestrial fan versus shelf gradients – the latter indicating a dominant allogenic control of eustatic sea-level changes at least in the south. While spatiotemporal variability in Late Quaternary precipitation and tectonic activity may constitute additional relevant factors, diachronism of northern CAF evolution could also be the response to individual autogenic fan dynamics.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"21 ","pages":"Article 100305"},"PeriodicalIF":2.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145747853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Trackways were monitored across multiple tidal cycles using photogrammetry to create timelapsed orthomosaics and digital elevation models. Our results exhibit a pattern of morphological footprint decay for individual tracks, while showing persistence at the same time. Under progressive influence of the tides, anatomical detail decreases, push-up ridges erode, and footprint outlines become wider with eventual sediment infill. Despite this, individual tracks remain identifiable and biometric inferences (e.g., foot length) are consistent throughout, with intra-trackway variability comparable to changes observed over time. Estimates for a complete removal of the tracks at the study sites are after five to seven days (10–14 tidal cycles). This will vary between sites as with variations in sediment properties, local hydrodynamics, and track orientation. We suggest that tidal duration is critical for footprint preservation and stress that taphonomic processes are different at sites with aeolian sediment formation. While site-specific, our results offer broader insights into the formation and survival of Quaternary footprints in dynamic coastal environments.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"21 ","pages":"Article 100317"},"PeriodicalIF":2.2,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show how three-item analysis is an efficient method capable of correctly analysing characters from lithic technologies that appear to be intrinsically hierarchical.
