The 4.2 ka BP Event in the Mediterranean region
The Mediterranean region and the Levant have returned some of the clearest evidence of a climatically dry period occurring around 4200 years ago. However, some regional evidence is controversial and contradictory, and issues remain regarding timing, progression, and regional articulation of this event. In this paper, we review the evidence from selected proxies (sea-surface temperature, precipitation, and temperature reconstructed from pollen, δ1…
Seasonality of Holocene hydroclimate in the Eastern Mediterranean reconstructed using the oxygen isotope composition of carbonates and diatoms from Lake Nar, central Turkey
A positive shift in the oxygen isotope composition ( δ 18 O) of lake carbonates in the Eastern Mediterranean from the early to late Holocene is usually interpreted as a change to drier (reduced precipitation and evaporation (P/E)) conditions. However, it has also been suggested that changes in the seasonality of precipitation could explain these trends. Here, Holocene records of δ 18 O from both carbonates and diatom silica, from Lake Nar in cent…
Early Holocene palaeoseasonality inferred from the stable isotope composition of Unio shells from Çatalhöyük, Turkey
Seasonal δ13C and δ18O data are presented from 14 Unio sub-fossil shells unearthed at the archaeological site of Çatalhöyük in central Turkey, spanning the occupation period ca. 9150–8000 cal years BP. The shells likely lived in the small lakes/wetlands around the site before being gathered and taken to Çatalhöyük. Wet-dry seasonal cycles are clearly apparent in the δ18Oshell profiles with low winter values reflecting winter precipitation and hig…
Is there an isotopic signature of the Anthropocene
We consider whether the Anthropocene is recorded in the isotope geochemistry of the atmosphere, sediments, plants and ice cores, and the time frame during which any changes are recorded, presenting examples from the literature. Carbon and nitrogen isotope ratios have become more depleted since the 19th century, with the rate of change accelerating after ~ad 1950, linked to increased emissions from fossil fuel consumption and increased production …
"Uses of the Past" on the Northwest Coast
Lors de l'epoque du commerce de la fourrure, les Russes ont etabli des relations plus etroites avec les « kwaans » (tribus) tlingit de l'archipel d'Alexandre en presentant des medaillons d'argent et des certificats, en distribuant des uniformes usagers aux chefs et en etablissant le titre de « principal chef Sitka Tlingit ». Dans les annees 1850 l'emploi des symboles hegemoniques euroamericains declina quand les Russes employerent les « cuivres »…
