The climatic downturn known globally as the Younger Dryas (YD; ∼12,900-11,500 BP) has frequently been cited as a prime mover of agricultural origins and has thus inspired enthusiastic debate over its local impact. This study presents seasonal climatic data from the southern Levant obtained from the sequential sampling of gazelle tooth carbonates from the Early and Late Natufian archaeological sites of Hayonim and Hilazon Tachtit Caves (western Galilee, Israel). Our results challenge the entrenched model that assumes that warm temperatures and high precipitation are synonymous with climatic amelioration and cold and wet conditions are combined in climatic downturns. Enamel carbon isotope values from teeth of human-hunted gazelle dating before and during the YD provide a proxy measure for water availability during plant growth. They reveal that although the YD was cooler, it was not drier than the preceding Bølling-Allerød. In addition, the magnitude of the seasonal curve constructed from oxygen isotopes is significantly dampened during the YD, indicating that cooling was most pronounced in the growing season. Cool temperatures likely affected the productivity of staple wild cereal resources. We hypothesize that human groups responded by shifting settlement strategies-increasing population mobility and perhaps moving to the warmer Jordan Valley where wild cereals were more productive and stable.paleoclimate | stable isotopes | δ 13 C | δ 18 O | Natufian

“…One detrital and overlying aragonite sublaminae constitute a varve. Previous studies (Prasad et al, 2004;Torfstein et al, 2013) indicate that small ice-rafting events (denoted as a, b, c, and d), as well as prominent Heinrich events in the North Atlantic, are associated with the eastern Mediterranean arid intervals. The study of seasonal sublaminae yields evidence of decadal to century scale arid events that correlate with cooler temperatures at higher latitudes.…”

Abstract. Recurrence-plot-based recurrence networks are an approach used to analyze time series using a complex networks theory. In both approaches -recurrence plots and recurrence networks -, a threshold to identify recurrent states is required. The selection of the threshold is important in order to avoid bias of the recurrence network results. In this paper, we propose a novel method to choose a recurrence threshold adaptively. We show a comparison between the constant threshold and adaptive threshold cases to study period-chaos and even period-period transitions in the dynamics of a prototypical model system. This novel method is then used to identify climate transitions from a lake sediment record.

“…Low lakes levels, during interglacial periods, result in halite deposition. Gypsum deposition is related to lakes level declines (i.e., Bartov, et al, 2003;Torfstein, et al, 2013;Neugebauer, et al, 2014).…”

Subsurface Seawater Intrusion, an Additional Factor Influencing the Limnological History of the Dead Sea Basin

A deep core hole, drilled in the middle of the Dead Sea penetrated the Pleistocene-Holocene section, revealed an alternating sequence of fresh water and evaporitic (gypsum, halite) deposits. The vertical facies variations were interpreted as related mainly to lake level changes during this period. The present study, however, proposes an additional factor that influenced these changes, namely subsurface seawater intrusion from the Mediterranean Sea to the endorheic Dead Sea Basin. This proposed process is controlled by the elevation and head difference between both base levels at a given time, because the Mediterranean Sea level also fluctuated during the discussed period. We find that in times of smaller head differences, and assumed lower seawater intrusion, a gypsum facies prevailed in the Dead Sea Basin. In times of greater head differences and assumed more abundant seawater intrusion a halite facies prevailed because of greater sodium chloride input into the Dead Sea.
