Abstract The early to middle Holocene Humid Period led a greening of today’s arid Saharo-Arabian desert belt. While this phase is well defined in North Africa and the Southern Arabian Peninsula, robust evidence from Northern Arabia lacking. Here we fill gap with unprecedented annually sub-decadally resolved proxy data Tayma, only known varved lake sediments Arabia. Based on stable isotopes, micro-facies analyses varve radiocarbon dating, distinguish five phases development show that wet...
<title>Abstract</title> The Sahara and the Sahel are currently experiencing an increase in rainfall during rainy season, possibly related to strengthening of hydrological cycle induced by global warming. However, slowdown Atlantic Meridional Overturning Circulation (AMOC) might be able counteract this trend, decreasing North African monsoon a timely, but highly uncertain, manner. During early mid-Holocene, experienced wet phase that offers good analogue for testing impact AMOC perturbation...
Cores from a large palaeolake, botanical macroremains out of archaeological features and surveys the actual vegetation in combination with pollen surface samples provide excellent records for reconstruction Holocene development vegetation, land use oasis cultivation Tayma region north-western Saudi-Arabia. The preliminary data suggest moderately denser cover during early mid Holocene. However, fluctuating but high frequencies desert throughout sequence show persistence ecosystems confirm...
The early to middle Holocene Humid Period (HHP) was the last time when precession-forced intensification of summer monsoons and northward migration associated rainfalls led a greening today’s arid Saharo-Arabian desert belt. While this wet phase is well confined in N Africa S Arabian Peninsula, robust evidence from Arabia lacking. Here, we fill gap with unprecedented annually sub-decadally resolved proxy data Tayma, only known varved lake sediments Arabia. Based on stable isotopes,...
&lt;p&gt;During the Holocene (0-11.7 ka BP), subtropical regions of Africa were characterized by very significant climatic changes. These changes evidenced variations in lake levels which reflect balance between precipitation and evaporation (P-E) at watershed scale. conditions are mainly associated with dynamics African summer monsoon relation location Intertropical Convergence Zone (ITCZ), is modulated insolation induced Earth's orbital parameters. This mechanism explains wetter...
