Holocene palaeoenvironmental reconstruction of sea level, coastal and vegetation changes along the southern Solway Firth, United Kingdom

open access: yesJournal of Quaternary Science, EarlyView.
Abstract Holocene relative sea level (RSL) changes were reconstructed from four sites along the less‐studied southern Solway Firth. A multiproxy approach, including lithostratigraphical and biostratigraphical analyses, combined with radiocarbon dating, produced ten sea level index points (SLIPs).

Biases in radiocarbon dating of organic fractions in sediments from meromictic and seasonally hypoxic lakes [PDF]

open access: yesBulletin of the Geological Society of Finland, 2019
We present here radiocarbon dating results from two boreal lakes in Finland, which are permanently (meromictic) or seasonally stratified and contain continuous sequences of annually laminated sediments that started to form in the early Holocene.

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Insights on the changing dynamics of cemetery use in the neolithic and chalcolithic of southern Portugal. Radiocarbon dating of Lugar do Canto Cave (Santarém) [PDF]

open access: yes, 2014
Lugar do Canto Cave is one of the most relevant Neolithic burial caves in Portugal given not only its extraordinary preservation conditions at the time of discovery but also the quality of the field record obtained during excavation. Its material culture

From Ice to Isolation: A geochemical reconstruction of the palaeoenvironmental evolution of Gairloch, NW Scotland (UK), since the Last Glacial Maximum

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...

On the astronomical origin of the Hallstatt oscillation found in radiocarbon and climate records throughout the Holocene

open access: yes, 2016
An oscillation with a period of about 2100-2500 years, the Hallstatt cycle, is found in cosmogenic radioisotopes (C-14 and Be-10) and in paleoclimate records throughout the Holocene. Herein we demonstrate the astronomical origin of this cycle.

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Radiocarbon Dating

open access: yesScottish Archaeological Internet Reports
Archaeological excavations conducted in 2017 at Grantown Road, Forres form the final phase of works on a residential development that began in 2002. The earlier works examined an area of more than 70ha and confirmed the presence of an extensive Iron Age settlement represented by ring-ditch, ring-groove, and post-ring structures, in association with ...
