Late Holocene Paleoclimate reconstruction of the northern Gulf of Aqaba using foraminifera as a proxy

A multiproxy analyses of sediment from a 4.3 m core extracted from 25 m water depth on the shelf of the northern Gulf of Aqaba suggest shifts in depositional environments over the past 4000 yrs.

Late Holocene hydrology inferred from lacustrine sediments of Laguna Cháltel (southeastern Argentina)

Precise timing of abrupt increase in dust activity in the Middle East coincident with 4.2 ka social change

An Iranian stalagmite record spanning 5.2 ka to 3.7 ka is presented, dated with 25 U/Th ages that provide an average age uncertainty of 31 y (1σ), and finds two periods of increased Mg/Ca, beginning abruptly at 4.51 and 4.26 ka, and lasting 110 and 290 y, respectively.

The 4.2 ka BP event in the Levant

Abstract. The 4.2 ka BP event is defined as a phase of environmental stress characterized by severe and prolonged drought of global extent. The event is recorded from the North Atlantic through

Speleothem Evidence for Megadroughts in the SW Indian Ocean during the Late Holocene

Abstract. The 4.2 ka BP event is widely described as a 200–300 years long interval of major climate anomaly (typically, arid and cooler conditions potentially across the globe), which defines the

Mid–late Holocene event registered in organo-siliciclastic sediments of Lagoa Salgada carbonate system, southeast Brazil

Abstract. The formation of the Paraíba do Sul river delta plain on the coast of Rio de Janeiro state, Brazil, gave rise to diverse lagoons formed under different sea level regimes and climate



Rainy periods and bottom water stagnation initiating brine accumulation and metal concentrations: 1. The Late Quaternary

A working hypothesis is proposed to account for the present accumulation of brines in isolated pockets of the ocean floor and for the formation of the underlying organic and metal-rich sediments.

Climate change at the 4.2 ka BP termination of the Indus valley civilization and Holocene south Asian monsoon variability

Planktonic oxygen isotope ratios off the Indus delta reveal climate changes with a multi‐centennial pacing during the last 6 ka, with the most prominent change recorded at 4.2 ka BP. Opposing

Mediterranean Moisture Source for an Early-Holocene Humid Period in the Northern Red Sea

It is concluded that Afro-Asian monsoonal rains did not cross the subtropical desert zone during the early to mid-Holocene and is best explained by enhancement and southward extension of rainfall from Mediterranean sources.

Renewal of deep water in the Red Sea during 1982–1987

Between October 1982 and May 1983 the deep water in the northern Red Sea was ventilated through slope convection. The deep water became cooler, fresher, and more oxygenated. Dense bottom water formed

Isotopic Composition and Origin of the Red Sea and Salton Sea Geothermal Brines

Abstract. Deuterium and oxygen-18 measurements show that the Red Sea and Salton Sea brines are the results of a single process, the leaching of sediments by surface water circulating downward to a

Climate and the Collapse of Maya Civilization

A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more intense multiyear droughts centered at approximately 810, 860, and 910 A.D.

Persistent Solar Influence on North Atlantic Climate During the Holocene

A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.

Climate change and the collapse of the Akkadian empire: Evidence from the deep sea

The Akkadian empire ruled Mesopotamia from the headwaters of the Tigris-Euphrates Rivers to the Persian Gulf during the late third millennium B.C. Archeological evidence has shown that this highly
