“…As suggested by Sivan et al (2011), Elyashiv et al (2016 and Shtienberg et al (2016), such units were deposited on the coastal plain as a result of stream overflows affected by rising sea level and a wetter climate, which changed from about 15 ka, as a result of the extreme insolation values ( Fig. 6c and d; Bar-Matthews et al, 2003;Revel et al, 2010;Langgut et al, 2011).…”

The stratigraphic architecture of coastal plains is determined by the interactions between local (e.g. fluvial processes and topography), regional (e.g. climate) and global (e.g. sea level) forcing factors, primarily during the Late Quaternary Period. Detailed stratigraphic and sedimentological analyses of boreholes, cored between coastal ridges in the lowlands, coupled with optically stimulated luminescence (OSL) dating, and integrated with existing onshore and offshore databases, has enabled a 4-D reconstruction of the evolution of the coast of Israel during the last glacial-interglacial cycle. This model revealed that Nilotic-sourced littoral sand, intermittently transported inland by wind, has either been lithified into aeolianite or pedogenized into orange-brown palaeosol from about 100 ka to 8 ka. Dark silty clay wetlands were deposited between the aeolian coastal ridges adjacent to streams which cut the Israeli coastal plain and flow westward, from the Last Glacial Maximum until the onset of the Holocene. These units are topped by beach and aeolian quartz sand dated to 6.6-0.1 ka. Diachronous thicknesses and lithological dissimilarities were identified between the sections studied and previous reports on adjacent coastal aeolianite ridges. Streams were found to be a dominant control on the stratigraphical composition and related facies architecture due to fluvial-induced erosion. Consequently, the relief variations between the lowland and cliff controlled aeolian pedogenesis as well as alluvial processes from about 80 to 5 ka. Climate, mainly influenced by precipitation and dust input, induced pedogenic processes; while sea level lowstand during the Last Glacial Maximum is shown to have hindered sediment deposition in the shallow offshore, which in turn affected aeolian transport, reducing sediment accumulation on the palaeo-coastal plain. The palaeoenvironmental model presented in the current study serves as an example for understanding the evolution of similar low-latitude siliciclastic-rich low-gradient shelf-coastal areas during the last glacial-interglacial cycle. Furthermore, it demonstrates the influence of local to global forcing factors on these environments.

Abstract. Detailed analyses of the Lake Van pollen, Ca / K ratio, and stable oxygen isotope record allow the identification of millennial-scale vegetation and environmental changes in eastern Anatolia throughout the last glacial (∼ 111.5-11.7 ka BP). The climate of the last glacial was cold and dry, indicated by low arboreal pollen (AP) levels. The driest and coldest period corresponds to Marine Isotope Stage (MIS) 2 (∼ 28-14.5 ka BP), which was dominated by highest values of xerophytic steppe vegetation.Our high-resolution multi-proxy record shows rapid expansions and contractions of tree populations that reflect variability in temperature and moisture availability. These rapid vegetation and environmental changes can be related to the stadial-interstadial pattern of Dansgaard-Oeschger (DO) events as recorded in the Greenland ice cores. Periods of reduced moisture availability were characterized by enhanced occurrence of xerophytic species and high terrigenous input from the Lake Van catchment area. Furthermore, the comparison with the marine realm reveals that the complex atmosphere-ocean interaction can be explained by the strength and position of the westerlies, which are responsible for the supply of humidity in eastern Anatolia. Influenced by the diverse topography of the Lake Van catchment, more pronounced DO interstadials (e.g., DO 19, 14, 12 and 8) show the strongest expansion of temperate species within the last glacial. However, Heinrich events (HE), characterized by highest concentrations of ice-rafted debris (IRD) in marine sediments, cannot be separated from other DO stadials based on the vegetation composition in eastern Anatolia. In addition, this work is a first attempt to establish a continuous microscopic charcoal record for the last glacial in the Near East.It documents an immediate response to millennial-scale climate and environmental variability and enables us to shed light on the history of fire activity during the last glacial.

Paleo‐denudation rates suggest variations in runoff drove aggradation during last glacial cycle, Crete, Greece

The impact of Quaternary climate cycles on denudation rates and fluvial aggradation and incision is debated, especially in non-glaciated regions. Here we present paleo-denudation rates and geochronological constraints on aggradation and incision from the Sfakia and Elafonisi alluvialfan sequences on Crete, Greece. We report seven optically stimulated luminescence (OSL), ten radiocarbon ages, and eight 10 Be and eight 36 Cl denudation rates from modern and terrace sediments. For five samples, 10 Be and 36 Cl were measured on the same sample by measuring 10 Be on cherts and 36 Cl on calcite. Results indicate relatively steady denudation rates throughout the past 80kyr, but the aggradation and incision history indicate a link with shifts in climate. At the Elafonisi fan, we identify four periods of aggradation coinciding with Marine Isotope Stages (MIS) 2, 4, 5a/b, and likely 6, and three periods of incision coinciding with MIS 1, 3, and likely 5e. At the Sfakia fan, rapid aggradation occurred during MIS 2 and 4, analogous to aggradation periods at the Elafonisi fan system, followed by up to 50 m of incision during MIS 1. Nearby climate and vegetation records show that MIS 2, 4, and 6 were characterized by cold and dry climates with sparse vegetation, whereas forest cover and wet conditions prevailed during MIS 1, 3, and 5. Our data thus suggest that past changes in climate had little effect on landscape-wide denudation rates, but exerted a strong control on the aggradation-incision behaviour of alluvial channels on Crete. During glacial stages, we attribute aggradation to hillslope sediment release promoted by reduced vegetation cover and decreased river sediment transport capacity; conversely, incision occurred during relatively warm and wet stages due to increased river transport capacity. We conclude that, in this landscape, past hydroclimate variations outcompeted changes in sediment supply as the primary driver of alluvial deposition and incision.
