However, a country-wide view of the LIA in China is still lacking, leading to ongoing debates about whether the LIA was a coherent, nationwide cold period. This study addresses this gap by analyzing the timing and spatial pattern of the LIA across China using the Last Millennium Climate Reanalysis. Key findings include: China experienced broadly cold conditions during the last millennium, but the LIA onset was notably asynchronous, in contrast to the near-synchronous termination of the LIA across China. Peak cooling occurred at different times in various regions, e.g., the 13th century in most of southern China, the 18th century in the eastern and western parts of the Qinghai-Tibet Plateau, and the 19th century in other areas. Generally, the magnitude of peak cooling increased with latitude. EOF analysis suggests the first mode accounts for 68.53 % of the total variance in temperature variability during 1200-1900 AD and indicates spatial consistency in temperature variability during this period. Weakening solar irradiance since the late 12th century is identified as the primary driver of these variations. The second mode explains 15.05 % of the total variance and reveals a north-south dipole pattern. Teleconnection factors such as the North Atlantic Oscillation and the Atlantic Multidecadal Oscillation significantly influence this mode. However, various monsoon systems across northern and southern China may play more important roles in this mode. The third mode accounts for 5.56 % of the total variance and displays tri-pole pattern (north-center-south), largely influenced by variations in the Pacific Decadal Oscillation, volcanic eruptions, and greenhouse gases. These findings provide full-field insights into the spatiotemporal characteristics of the LIA in China and enhance our understanding of this historical climate event.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"745 ","pages":"Article 109935"},"PeriodicalIF":1.9,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used summertime mooring data from the Alaskan Beaufort Shelf to study sediment-transport patterns which are dominated by waves and wind-driven currents. Easterly wind events account for most of the seasonal sediment transport, and serve to focus sediment on the inner shelf. This is a key finding because it means that sediment is readily available for wave-driven resuspension and sea-ice entrainment during fall storms. Sediment-ice entrainment has been previously implicated as a major mechanism for Arctic Shelf erosion—and so the summertime focusing of sediment observed in this study may actually serve to enhance shelf erosion rather than promote shelf sediment accumulation. In a pan-Arctic context, the Alaskan Beaufort Shelf is somewhat similar to the Laptev Sea Shelf, where previous work has shown that sediment is also focused during the summer months (but for different reasons related to estuarine-like circulation under the Laptev plume). The Alaskan Beaufort Shelf example contrasts with previous work on the Canadian Beaufort Shelf, where dominant winds from the opposite direction (northwest) likely promote strong seaward dispersal of sediment rather than inner-shelf convergence. This study thus highlights the importance of understanding dominant wind patterns when considering seasonal and inter-annual storage, transport, and erosion of sediments from Arctic continental shelves.</p>","PeriodicalId":54340,"journal":{"name":"Journal of Geophysical Research-Oceans","volume":"130 7","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite various reconstruction attempts, a consensus on their history remains elusive. Chert, valued for its diagenetic stability, offers a promising archive, particularly through triple oxygen isotope analysis. However, Precambrian cherts frequently exhibit deviations in δ¹⁸O and Δ^’17O from triple oxygen isotope equilibrium, complicating interpretations. Here, we propose that this deviation results from the coprecipitation of oxygen-bearing minerals (detrital silicates, authigenic clays, and barite), each with distinct isotopic signatures. To test this hypothesis, we analyzed Mesoproterozoic chert samples from the Yangzhuang and Wumishan formations in North China. Our results show a significant correlation between chert δ¹⁸O and detrital silicate content, with coexisting oxygen-bearing minerals driving deviations in δ¹⁸O and Δ^’17O from equilibrium. The δ¹⁸O and Δ^’17O values of the purest, most pristine chert samples suggest that Mesoproterozoic seawater had a δ¹⁸O similar to that of modern seawater (i.e. ∼ -1 ‰, ice free world seawater), a conclusion further supported by our oxygen balance model.

The flows transported large volumes of boulders to downstream fans, devastating Montecito, California. With rainfall-runoff modeling, lidar, photogrammetry, and field surveys, we quantified the hydrological and sedimentological components of the debris flows as they evolved from hillslope runoff to boulder-rich fan deposits and ocean discharge. Runoff from burned soils drove larger amounts of rill erosion and slurry generation on shale hillslopes than on sandstones. Hillslope slurry mobilized ravel deposits and fine sediments stored in the channel network, mainly on shales. Channels draining sandstones mainly supplied the flows' boulder loads. One-quarter of the mountain-shed sediment escaped to the ocean, while all boulders settled on the fans. Flows confined to primary channels remained erosive across the fans except where channel gradients and dimensions decreased in response to fault-related topography and where bridges trapped boulders, intensifying in-channel and overbank deposition. Although the results derive from a single event, they illustrate how a sequence of processes and landscape conditions determine debris-flow evolution across catchments and fans.

To address this research gap, we quantify and map heat risks and shelter provisions of administrative neighborhoods (often the smallest level of urban governance) and walkable grids of 500 × 500 m (a commonly-used comfortable walking distance for vulnerable groups such as the elderly people), and identify vulnerable areas where heat mitigation interventions should be prioritized.
