To date, the sensitivity of the Indonesian Throughflow (ITF) and the Asian-Australian monsoon dynamics to changing MBE climate have not been well documented. Here, we investigated clay mineral, grain size and radiogenic isotopic records of the International Ocean Discovery Program (IODP) Site U1483 from the eastern Indian Ocean off northwest Australia over the last 795 kyr. This study provides crucial insights into the sediment source, long-term variability of the ITF and its influence on the Australian summer monsoon and the oceanic and atmospheric systems interplay across the MBE. Clay minerals and Sr-Nd-Pb isotopes suggest that the sediments of Site U1483 are primarily from the Kimberley region of northwest Australia with minor contributions from the Timor region carried by the ITF. Kaolinite/smectite ratio coupled with mean grain size were adopted to indicate variability in the intensity of the ITF and Australian monsoon. High values of kaolinite/smectite and mean grain size during interglacials indicate a strong ITF, which may have contributed to maintaining the humid Australian summer monsoon with high river discharge over the last 795 kyr. In contrast, low values imply a weak ITF, which might have been one of the major amplifying factors resulting in dry conditions over northwest Australia during glacials. Spectral and wavelet analyses of the proxy records display the concentration of power on 100-kyr, 41-kyr and 23-kyr bands, implying jointly effects of sea level variations associated with the global ice volume and expansion/contraction of the Intertropical Convergence Zone on the paleoclimate and clay minerals sedimentation along northwest Australia. The long-term variations of clay minerals, grain size and their relevant proxy records from Site U1483 display a remarkable shift at an earlier stage of MIS 12, coinciding with the MBE. We attribute this shift to the submergence of sediment source areas and enhanced ITF due to sea-level rise in recent interglacials. Our findings provide insights into the line of evidence that the ITF and Australian monsoon became increasingly forced by the global sea level change and the MBE was a global phenomenon influencing both the monsoonal and oceanic systems.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"359 ","pages":"Article 109366"},"PeriodicalIF":3.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the ‘Marmara Transition Zone’ in northwest Türkiye, a region of significant societal transformation, lacks high-resolution pre-industrial climate records. Continuous paleoclimate reconstructions are critical to reveal the nature and pattern of Late Holocene hydroclimatic changes and extremes, and to study their impacts on societies. Here, we present a precisely dated and sub-decadal resolution speleothem record from Uzuntarla cave, located near to Istanbul (historically Byzantium and Constantinople), that shows sensitivity to cold-season rainfall amount and seasonality for the Late Holocene. Prior to 2005 CE, stalagmite U-1 reveals two periods of high multidecadal variability of cold-seasonal rainfall in ∼1900-400 BCE and ∼690–1900 CE, separated by a relatively stable phase. This variability aligns with the rise and fall of Byzantine agrarian productivity between ∼350 and 1250 CE, while the most pronounced aridification anomaly in ∼1210-1170 BCE coincides with the collapse of the Hittite Empire (c. ∼1200 BCE), partly linked to regional famine and drought. Our findings indicate that the transition from the Late Bronze Age to the Iron Age in the Marmara Transition Zone was marked by a pronounced shift in the regional climate regime. Namely, that a previously warmer and more stable 'Mediterranean-style' climate shifted toward cooler conditions characterised by increased rainfall variability, and a greater influence of moisture sourced from the Black Sea. Therefore, we suggest that cold-seasonal rains played a critical role in shaping human-climate interactions, power dynamics, and social stability in the Eastern Mediterranean during the Late Holocene. This record offers valuable context for understanding how hydroclimate variability influenced past societies, highlighting the importance of climate as a driver in historical societal resilience and collapse.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"359 ","pages":"Article 109365"},"PeriodicalIF":3.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sediment cores 2008029-059 PC and TWC (59CC) and 2013029-064 PC (64 PC) from Lancaster Sound and Baffin Bay, respectively, represent LGM through Holocene environments, including three Baffin Bay Detrital Carbonate (BBDC) events that have been thought to manifest calving events within Lancaster Sound. Previous mapping of glacigenic landforms shows that 64 PC lies within the LGM limit of the convergent BLIS and Tasiujaq Ice Stream (TIS) on the northeastern Baffin Island shelf, while 59CC terminates within subglacial/ice marginal sediments termed the Baffin Shelf Drift (BSD), capturing the history of BLIS retreat from 15.3 cal ka BP onward. In 64 PC, a basal sediment gravity flow deposit is overlain by dolomite-rich BBDC 2, which is re-interpreted here as a subglacial/ice marginal deposit and renamed GZ-BBDC. Both gravity flows are interpreted to have formed during retreat of the confluent TIS and BLIS from the LGM maximum extent. Overlying GZ-BBDC, in 64 PC, is a finely laminated lithofacies interpreted as an ice-shelf facies formed beneath the ice shelf fronting the confluent TIS and BLIS when it occupied a large LGM grounding zone wedge (GZW) in northern Baffin Bay. The ice-shelf facies indicates temporary stabilization of the conjoined TIS and BLIS. The overlying thin black glaciomarine diamicton records disintegration of the ice shelf and retreat of the TIS. Ice retreat over Cretaceous and younger bedrock into Lancaster Sound is recorded by dark brown diamicton and glaciomarine sediments in 59CC. The overlying tan, detrital carbonate-rich glaciomarine diamicton, BBDC 1 in 59 PC, manifests calving retreat of the BLIS onto the Paleozoic carbonate bedrock within Lancaster Sound by 15 cal ka BP. A slightly later onset of BBDC 1 in 64 PC, of ca.14.5 cal ka BP, points to the influence of local conditions such as sea ice and local iceberg calving on the distribution of IRD off of Pond Inlet. The pause in ice rafting and detrital carbonate deposition between BBDC 1 and BBDC 0 within the Younger Dryas chron likely results from BLIS readvance to Devon Island and its stabilization there until 11.6 cal ka BP. BLIS retreat into Prince Regent Inlet marks the onset of BBDC 0. These new results indicate multiple periods of instability of the BLIS, which are responsible for BBDC events identified throughout Baffin Bay.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"358 ","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we performed a detailed bathymetric analysis and generated a series of palaeogeographic models using a Geographic Information System (GIS) and Digital Elevation Models (DEM).

However, the complexity of interpreting and comparing several proxies from diverse sites complicates the characterization and differentiation of climatic and environmental changes at local, regional and global scales. This study investigates a 6-m peat core from the Ngaoundaba maar volcanic crater (Northeastern Cameroon, later simply called Ngaoundaba), spanning the last 10 ka using pollen analysis and a large panel of lipid biomarkers. We produce new high-resolution, continuous, multiproxy records of vegetation, temperature, and precipitation spanning most of the Holocene. All of these proxies indicate a substantial transition approximately 5.7–5.6 ka cal BP, which is supported by cluster analyses and marks the end of the AHP. A shift from an open-water to a vegetated peatland, the disappearance of some wooded species, and the expansion of grass and sedge pollen all indicate significant local and regional changes. The gradual terrestrialization of peat surfaces also had an impact on lipid biomarker proxies. An unusual extensive variation in hydrogen isotopic composition (D/H) of long-chain <em>n</em>-alkanes during the Holocene, in contrast to other records from West and Central Africa, may be attributed to the increased contribution from local wetland plants, including sedges and grasses, which thrive in peat water that is more D-enriched than rainwater, peat water being the water accumulating in the wetland. Likewise, temperature variations reconstructed using bacterial branched glycerol dialkyl glycerol tetraethers (brGDGTs) are influenced by confounding factors, like changes in peat pH or moisture levels, which may be constrained using our multiproxy methodology. The temperature record from Ngaoundaba indicates a slight increase in temperature during the mid-Holocene relative to pre-industrial levels. The Ngaoundaba peat deposit documents a massive and abrupt shift in vegetation at the end of the AHP, linked with changes in precipitation amount and/or seasonality, which also significantly affected the peat microbial community. The Ngaoundaba peat record, because of its high sensitivity to climatic and environmental changes, is a crucial new source for understanding the end of the African Humid Period in Western Central Africa.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"358 ","pages":"Article 109307"},"PeriodicalIF":3.2,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 integrates multiple lines of evidence, including macro-botanical data recovered from archaeological sites, pollen taxa analysis from high-resolution sediment samples, and species distribution modeling (SDM), to evaluate the interaction between wild cereal resources and human choices during Holocene climate fluctuations. The findings suggest that climatic amelioration following the Last Glacial Maximum (LGM) may facilitate the availability of wild broomcorn millet and rice in northern China. Their high abundance during the early Holocene may make these cereals dominant choices. In contrast, the climatic impact on wild foxtail millet was minimal, and its relatively lower availability likely constrained its early consumption. During the early Holocene, the composition of local vegetation may have influenced the proportion of cereals in daily diets. By the mid-Holocene, although climatic fluctuations diminished the availability of wild broomcorn millet and rice, the expansion of agriculture became the primary driver for the widespread dominance of foxtail millet. The assessment of early human adaptation reveals that the selective utilization of cereals was part of a complex ecological and economic dynamic, initially driven by disparities in plant resource availability resulting from Holocene climatic variations.
