Unanswered questions about the glacier and climate history preceding the\u0000global Last Glacial Maximum (LGM) in the southern temperate latitudes\u0000remain. The Marine Isotope Stage (MIS) 3 is normally understood as a global\u0000interstadial period; nonetheless its climate was punctuated by conspicuous\u0000variability, and its signature has not been resolved beyond the polar realms. In this paper, we compile a 10Be depth profile, single grain infrared (IR) stimulated luminescence dating and 14C samples to derive a new glacier record for the principal outwash plain complex, deposited by the western Patagonian Ice Sheet (PIS) during the last glacial period (Llanquihue Glaciation) on the Isla de Chiloe, southern Chile (42 ∘ S).

No environmental factor has been as critically important for Egypt's ancient society through time as sufficiently high annual flood levels of the Nile River, the country's major source of fresh water. However, interpretation of core analysis shows reduced depositional accumulation rates and altered compositional attributes of the sediment facies deposited seaward of the Nile Delta during a relatively brief period in the late third millennium BCE. These changes record the effects of displaced climatic belts, decreased rainfall, lower Nile flows, and modified oceanographic conditions offshore in the Levantine Basin, primarily from 2300 to 2000 BCE, taking place at the same time as important geological changes identified by study of cores collected in the Nile Delta. It turns out that integrated multi-disciplinary Earth science and archaeological approaches at dated sites serve to further determine when and how such significant changing environmental events had negative effects in both offshore and landward areas. This study indicates these major climatically induced effects prevailed\u0000concurrently offshore and in Nile Delta sites and at about the time Egypt\u0000abandoned the Old Kingdom's former political system and also experienced\u0000fragmentation of its centralized state. In response, the country's\u0000population would have experienced diminished agricultural production leading to altered societal, political, and economic pressures during the late Old Kingdom to First Intermediate Period at ca. 2200 to 2050 BCE.","PeriodicalId":227489,"journal":{"name":"EG Quaternary Science Journal","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122842959","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}

Key elements of sacred landscapes of the Nile Delta were\u0000lakes, canals and artificial basins connected to temples, which were built\u0000on elevated terrain.

Lake Mareotis (modern Mariut), located near the Mediterranean\u0000coast of Egypt west of the Nile Delta, is bordered by ancient sites dating\u0000from the New Kingdom (end of the 2nd millennium BCE) to the Medieval period (8th\u0000century CE), the most famous one being Alexandria. In its western part (wadi\u0000Mariut), several sites are equipped with harbour structures, but they also have\u0000structures contemporaneous with them that are not compatible with the lake\u0000level required for the operation of the harbour.

This study uses an integrated multi-method\u0000geoarcheological and geochronological approach to contribute to the\u0000understanding of the timing and stratigraphy of the monumental burial mound royal tomb (Konigsgrab) of Seddin. We show that the hitherto\u0000established radiocarbon-based terminus post quem time frame for the\u0000construction of the burial mound of 910–800 BCE is supported by optically\u0000stimulated luminescence (OSL) dating. The radiocarbon samples were obtained\u0000from a substrate directly underneath the burial mound which supposedly\u0000represents the late glacial/Holocene soil that was buried below the\u0000structure. We use sedimentological (grain-size analyses) and geochemical\u0000analyses (element analyses, carbon, pH, and electric conductivity\u0000determinations) to reassess and confirm this hypothesis. In addition to the\u0000burial age associated with the last anthropogenic reworking during\u0000construction of the burial mound, the OSL dating results provide new\u0000insights into the primary deposition history of the original substrates used\u0000for the structure.

The contribution highlights the use of Landsat spectral-temporal metrics (STMs) for the detection of surface anomalies that are potentially related to buried near-surface paleogeomorphological deposits in the Nile Delta (Egypt), in particular for a buried river branch close to Buto. The processing was completed in the Google Earth Engine (GEE) for the entire Nile Delta and for selected seasons of the year (summer/winter) using Landsat data from 1985 to 2019. We derived the STMs of the tasseled cap transformation (TC), the Normalized Difference Wetness Index (NDWI), and the Normalized Difference Vegetation Index (NDVI). These features were compared to historical topographic maps of the Survey of Egypt, CORONA imagery, the digital elevation model of the TanDEM-X mission, and modern high-resolution satellite imagery. The results suggest that the extent of channels is best revealed when differencing the median NDWI between summer (July/August) and winter (January/February) seasons ( ΔNDWI ). The observed difference is likely due to lower soil/plant moisture during summer, which is potentially caused by coarser-grained deposits and the morphology of the former levee. Similar anomalies were found in the immediate surroundings of several Pleistocene sand hills (“geziras”) and settlement mounds (“tells”) of the eastern delta, which allowed some mapping of the potential near-surface continuation. Such anomalies were not observed for the surroundings of tells of the western Nile Delta. Additional linear and\u0000meandering ΔNDWI anomalies were found in the eastern Nile Delta in the immediate surroundings of the ancient site of Bubastis (Tell Basta), as well as several kilometers north of Zagazig. These anomalies might indicate former courses of Nile river branches. However, the ΔNDWI does not provide an unambiguous delineation.","PeriodicalId":227489,"journal":{"name":"EG Quaternary Science Journal","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132138822","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}
