Abstract. The eastern Mediterranean surface circulation is highly energetic and composed of structures interacting stochastically. However, some main features are still debated, the behavior fine-scale dynamics their role in shaping general yet unknown. In following paper, we use an unsupervised neural network clustering method to analyze long-term variability different mesoscale structures. We...

Microplastic pollution is a pervasive anthropogenic phenomenon at the ocean surface. Numerous studies have been performed worldwide; nevertheless, distribution patterns, morphological properties, and sources of origin in Eastern Mediterranean Sea are still poorly explored. The purpose this study to investigate patterns surface floating microplastics (MPs) Ionian, Aegean, Levantine Seas relation...

Controlled experiments using a calibrated crossbow to thrust stone-tipped spears into animal carcasses reveal a relationship between Levallois point morphology and their performance as spear points. A comparative study of morphometric variation of Levallois points from Levantine Mousterian contexts supports the hypothesis that the demand for stone spear points was an important factor in Levallo...

The Arabic language is characterized by the existence of many different colloquial varieties that significantly differ from the standard Arabic form. In this paper, we propose a state-of-the-art speech recognition system for Levantine Colloquial Arabic (LCA). A fully continuous context dependent acoustic model was trained using 50 hours of speech from the BBN DARPA Babylon corpus. Pronunciation...

Aim Although thermophilous and arid-dwelling relict biotas constitute a singular component of European biodiversity high conservation value, we still largely ignore their biogeographic history. In this study, investigate the geographical diversification Maghrebian-Levantine crested grasshopper its colonization semiarid habitats southeastern Iberia to gain insights into historical processes unde...

High-resolution benthic foraminiferal and geochemical investigations were carried out across sapropels S5 and S6 from two sediment cores in the Levantine Sea to evaluate the impact of climatic and environmental changes on benthic ecosystems during times of sapropel formation. The faunal successions indicate that eutrophication and/or oxygen reduction started several thousand years prior to the ...

Abstract. The subsurface oxygen maximum (SOM) is observed in oligotrophic oceans and associated with different physical biological processes. This study characterizes the SOM Mediterranean Sea at basin scale investigates its driving mechanisms by analysing output of 1/24∘ resolution biogeochemical reanalysis provided Copernicus Marine Service for 1999–2019 time period. We validated model-derive...
