Abstract 230 Th normalization is a valuable paleoceanographic tool for reconstructing high‐resolution sediment fluxes during the late Pleistocene (last ~500,000 years). As its application has expanded to ever more diverse marine environments, nuances of systematics, with regard particle type, size, lateral advective/diffusive redistribution, and other processes, have emerged. We synthesized over 1000 sedimentary records from across global ocean at two time slices, Holocene (0–5,000 years...

Abstract The tectonically driven Cenozoic closure of the Tethys Ocean invoked a significant reorganization oceanic circulation and climate patterns on global scale. This process culminated between Mid Oligocene Late Miocene, although its exact timing has remained so far elusive, as does subsequent evolution proto-Mediterranean, primarily due to lack reliable, continuous deep-sea records. Here, we present for first time framework Oligo–Miocene deep Levant Basin, based chrono-, chemo- bio-...
Northern and eastern Africa were exposed to significantly wetter conditions relative present during the early Holocene period known as African Humid Period (AHP), although latitudinal extent of northward expansion tropical rain belt remains poorly constrained. New records 230Thxs-normalized accumulation rates in marine sediment cores from Red Sea Gulf Aden are combined with existing western dust terrestrial across Sahara Desert, revealing that fluxes transported east decreased by at least...
Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity affected by different environmental factors including anthropogenically forced climate change. Until now, historical changes have not been fully assessed at the global scale. Here we present FORCIS (Foraminifera Response to Climatic Stress) database on foraminiferal species from 1910 until 2018 published unpublished data. The includes...
Heavy metal inputs into marine environments and their effect on organisms are of major concern. Here, we examined the potential use two invasive ascidian species, Phallusia nigra Microcosmus exasperatus, as bio-indicators 11 HMs in Mediterranean Red Sea coasts Israel. Individuals were collected a seasonal basis from three sites over one year, analysis was carried out seperatly for tunic body. Both species accumulated high levels HMs, which varied seasonally spatially. In M. exasperatus...
Abstract A highly resolved time series of dissolved major element (calcium, strontium, magnesium, and lithium) concentrations in the north Gulf Aqaba, Red Sea, reveals variability cation beyond analytic uncertainties. This is composed an interannual component that most important for calcium, a short‐term daily‐timescale lithium. As evident from covariation potential alkalinity, Sr/Ca, calcium carbonate cycle Aqaba dominated by coral calcification, there was increase calcification rates...
Calcifying foraminifera from the orders Rotaliida and Miliolida are widely used as geochemical proxies for recording paleoceanographic conditions, while agglutinated often overlooked since their tests mostly composed of foreign particles. This study investigated properties Textularia agglutinans, a cosmopolitan benthic species order Textulariida which has an exceptional inner calcareous test is evolutionarily basal to Rotaliida. confirms evolutionary link between textulariids rotaliids based...
Abstract Jara‐Muñoz et al. report a new set of U‐Th and 14 C dates obtained from stromatolites scattered along the western slopes Dead Sea escarpment use them to establish lake‐level curve for part last glacial cycle. This is fundamentally different previous reconstructions (Bartov al., 2002, 2003; Hazan 2005; Lisker 2009; Machlus 2000; Torfstein, Goldstein, Stein, & Enzel, 2013) characterized by very significant vertical uncertainties, which in practice, ignore millennial‐timescale...
