A tephrostratigraphic investigation of the continuously varved Holocene Boreal lake Nautajärvi, Finland, provides precise age estimate for Lairg A/Hekla 5 eruption Open
Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resol…
Holocene climate evolution and human activity as recorded by the sediment record of lake Diss Mere, England Open
Lake sediments are ideal archives to evaluate the interactions between climatically driven environmental responses and human activity on seasonal to multi‐decadal timescales. This study focuses on the unique sediments of Diss Mere, the onl…

Revisiting the Tianwen Yellow Pumice (TYP) Eruption of Changbaishan Volcano: Tephra Correlation, Eruption Timing and Its Climatostratigraphical Context Open
Changbaishan volcano (China/North Korea) is one of the most active and hazardous volcanic centers in Northeast Asia. Despite decades of intensive research, the eruption history of this stratovolcano remains poorly constrained. One of the m…
Geochemical characterization of Anatolian tephras from Late Middle and Early Upper Palaeolithic sites in the Jebel Qalkha area, southern Jordan Open
The Middle to Upper Palaeolithic transition in the Levant is characterized by key archaeological shifts, including the interaction between Neanderthals and AMH and the appearance and dispersal of the Upper Palaeolithic. During this period …

Palaeoenvironmental and chronological context of hominin occupations of the Armenian Highlands during MIS 3: Evidence from Ararat-1 cave Open
Archaeological and palaeoenvironmental evidence from the Armenian Highlands and wider southern Caucasus region emphasises the significance of Marine Oxygen Isotope Stage 3 (c. 57–29 ka) as a crucial period for understanding hominin behavio…

Fire History in the Qinling Mountains of East‐Central China Since the Last Glacial Maximum Open
The study of fire history and driving mechanisms at long time scales can provide a theoretical background for future fire management in forested regions. The alpine lake sediments from Daye Lake in the Qinling Mountains, east‐central China…
Distal tephra reveal new MIS 5e Kos eruptions: Implications for the chronology and volcanic evolution histories in the Eastern Mediterranean region Open
The Kos Plateau Tuff (KPT), was an enormous caldera forming eruption originating from a vent within the Kos/Nisyros/Yali volcanic complex, occurring at 161 ka. It is the largest recognised Late Quaternary eruption in the Eastern Mediterran…
Updated age constraints on key tephra markers for NW Europe based on a high-precision varve lake chronology Open
Cryptotephra layers deposited in annually-laminated (varved) lake records can be precisely dated and used as a means to correlate archives, testing the spatio-temporal variability of climatic transitions, environmental change and human act…
Rare Holocene sediment deposits from Sodmein Playa (Eastern Desert, Egypt)—Stratigraphic assessment and environmental setting Open
Sodmein Playa is one of the rare Pleistocene open‐air sites in the Eastern Desert of Egypt. Based on the associated stone artefact material, it could be assigned to the Middle Stone Age/Last Interglacial. However, it has not yet been possi…

Holocene deglaciation and glacier readvances on the Fildes Peninsula and King George Island (Isla 25 de Mayo), South Shetland Islands, NW Antarctic Peninsula Open
To provide insights into glacier-climate dynamics of the South Shetland Islands (SSI), NW Antarctic Peninsula, we present a new deglaciation and readvance model for the Bellingshausen Ice Cap (BIC) on Fildes Peninsula and for King George I…
Holocene Tephrostratigraphy in the East Sea/Japan Sea: Implications for Eruptive History of Ulleungdo Volcano and Potential for Hemispheric Synchronization of Sedimentary Archives Open
Active volcanoes in East Asia pose potential threats to the surrounding areas. The eruptive history of many of the Japanese volcanoes are well understood, but their dispersal pathways are often based on visible tephra. Additionally, other …

Environmental factors influencing spotted hyena and lion population biomass across Africa Open
The spotted hyena ( Crocuta crocuta Erxleben) and the lion ( Panthera leo Linnaeus) are two of the most abundant and charismatic large mammalian carnivores in Africa and yet both are experiencing declining populations and significant press…
Complexities in European Holocene cryptotephra dispersal revealed in the annually laminated lake record of Diss Mere, East Anglia Open
Annually-laminated (varved) lake records serve as valuable archives for the study of subtle variations in the timing and expression of changing environmental and climatic conditions at sub-decadal resolution. Well-constrained, individual c…
The First Holocene Varve Chronology for the UK: based on the integration of varve counting, radiocarbon dating and tephrostratigraphy from Diss Mere (UK). Open
<p>This paper reports the first Holocene varved chronology for the lacustrine sediment record of Diss Mere in the UK. The record of Diss Mere is 15 m long, and shows 4.2 m of finely-laminated sediments, which are present between ca. …
Cryptotephras in the Lateglacial ICDP Dead Sea sediment record and their implications for chronology Open
Due to a lack of visible tephras in the Dead Sea record, this unique palaeoenvironmental archive is largely unconnected to the well‐established Mediterranean tephrostratigraphy. Here we present first results of the ongoing search for crypt…
