Here, we present a paleoenvironmental reconstruction based on geochemical data and biological proxies such as ostracods and ephippia from cladocerans from the Santa Clara basin, at the southern Chihuahua Desert, during the last 18.7 cal ka. Overall, cold and humid conditions between 18.7 and 15 cal ka BP prevailed in the Santa Clara region without ostracod preservation. During the warmer Bølling-Allerød, <i>L. axalapasco</i> presented higher productivity; however, this species did not occur during the colder Younger Dryas. The early Holocene was marked by a general trend towards warmer and dryer conditions, and a sedimentary hiatus was detected from 10.7 to 6.4 cal ka BP. Subsequently, when the North American Monsoon reached its maximum extension, ostracods exhibit their maximum total abundance during 6–4.8 cal ka BP, indicating warmer and shallower lake conditions. The presence of only females of <i>L. bradburyi</i> between 4–2 cal ka BP possibly suggests lower lake water temperatures associated with enhanced winter precipitation under El Niño type conditions. Finally, during the last 2 cal ka ephippia, <i>L. axalapasco</i> females and geochemical data suggest the driest period of the record as the ITCZ continued moving southwards. This work reveals the marked sensitivity of southern Chihuahua Desert ecosystems to the climatic shifts that occurred since the Last Glacial Maximum, and this perhaps indicates their vulnerability to future global warming reducing monsoonal precipitation.</p>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"40 4","pages":"634-644"},"PeriodicalIF":1.9,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jqs.3706","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach provides intriguing insights into local deglaciation and postglacial processes; however, certain aspects of the applied methodology and data interpretation require further elaboration. The commentary draws attention to challenges related to the limited availability of SDQ index data for the m1 teeth of the genus <i>Arvicola</i>, which may affect the precision of the correlations. Additionally, we emphasise the necessity of incorporating more detailed lithological analyses to complement the proposed stratigraphic conclusions. Assigning key sedimentary units to global chronostratigraphic frameworks, in some cases, necessitates a stronger consideration of regional correlations based on available palaeopedological and malacological data from neighbouring areas.

We use new high-resolution multibeam-echosounder bathymetry data to map the submarine geomorphology of a former tidewater glacier that drained the Skye Icefield, NW Scotland, during the Younger Dryas Stadial (Greenland Stadial 1) ca. 12.9–11.7 ka. Our onshore and offshore mapping identifies a glacial landform assemblage indicative of surge-type behaviour, followed by rapid retreat and stagnation. We delimit three separate fjord-mouth advances of the Ainort Glacier — interpreted as palaeo-surges — successively decreasing in extent. During the quiescent phase of the final surge cycle, the glacier deposited a suite of cross-fjord De Geer moraines, interpreted here as annual moraines. Their pattern and spacing suggest that net annual glacier retreat rates increased significantly from around 25–75 ma⁻¹ to 150 ma⁻¹ to &gt;300 ma⁻¹, probably in the presence of seasonal sea ice. On this basis, we find that final post-surge retreat of the Ainort Glacier, from fjord mouth to marine limit (a distance of 3.5 km), was very rapid — probably taking just 20 years. Once wholly terrestrial, the glacier stagnated and did not experience further frontal oscillations. This work highlights one potential cause of asynchronous ice-mass responses in the Younger Dryas Stadial of Scotland and reinforces the importance of identifying surge-type glaciers in palaeoglaciological studies.</p>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"40 4","pages":"622-633"},"PeriodicalIF":1.9,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jqs.3701","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we provide the first evaluation of the full extent of NS glaciation in the Wicklow Mountains by combining solar radiation modelling, mapping of glacial geomorphology, ¹⁰Be and ²⁶Al cosmogenic surface exposure dating, 3D glacier reconstructions and analysis of snowblow and avalanching potential. We identify seven sites that hosted cirque glaciers at this time. Glacier extent was very restricted, with most glaciers only partially filling their cirques.

Higher snowblow and avalanching contributions at sites with lower ELAs demonstrate local topoclimatic influence on glacier growth and preservation alongside regional climate.
