Abstract. The Mediterranean region and the Levant have returned some of clearest evidence a climatically dry period occurring around 4200 years ago. However, regional is controversial contradictory, issues remain regarding timing, progression, articulation this event. In paper, we review from selected proxies (sea-surface temperature, precipitation, temperature reconstructed pollen, δ18O on speleothems, lacustrine carbonate) over Basin to infer possible climate patterns during interval...
Abstract Reconstruction of last millennia Sea Surface Temperature (SST) evolution is challenging due to the difficulty retrieving good resolution marine records and several uncertainties in available proxy tools. In this regard, Roman Period (1 CE 500 CE) was particularly relevant socio-cultural development Mediterranean region while its climatic characteristics remain uncertain. Here we present a new SST reconstruction from Sicily Channel based Mg/Ca ratios measured on planktonic...
Abstract. A new high-resolution deglacial and Holocene sea surface temperature (SST) reconstruction is presented for the Alboran Sea (western Mediterranean), based on Mg∕Ca ratios measured in planktonic foraminifera Globigerina bulloides. This record evaluated by comparison with other SST records previously published alkenone reconstructions from same region both glacial periods. In all cases there a high degree of coherence between different but strong discrepancies when compared to...
Reconstructing past changes in oxygen content can be challenging due to some limitations of the proxies used, which are often not continuously represented sedimentary record. Here, we present a series reconstructions Mediterranean Sea based on measurement U/Mn ratios over foraminifera diagenetic coatings. We first test feasibility proxy through different locations and explore fixation geochemical signal foraminiferal carriers redox zone. The is further tested by direct comparison with...
This study presents the first high-resolution speleothem-based hydrological reconstruction for much of last 2.7 kyr in central-western Mediterranean. The paleohydrological information comes from a combination five U-Th dated stalagmites two Mallorca island caves. Interpretations are based on records δ18O, δ13C and trace element analyses combined with mineralogical X-ray diffraction, fabrics morphological features, cave monitoring data. None studied cover whole period but they provide...
Abstract Eastern Mediterranean deep-intermediate convection was highly sensitive to varying inputs of fresh water fluxes associated with increased rainfall during the African Humid period (15-6 kyr Before Present). Here we investigate changes in water-outflow from Sea since last deglaciation using neodymium isotope ratios. Our results indicate enhanced outflow Younger Dryas, two times higher than present-day and about three Sapropel. We propose that into western over Dryas result combined...
Cold-water coral (CWC) mounds are widely distributed in the eastern Alboran Sea (westernmost Mediterranean), specifically so-called East and West Melilla CWC mound provinces (EMCP, WMCP). Here we present a study on environmental changes that occurred WMCP since last deglaciation (~14 kyr BP), based analysis of sediment core MD13-3451 (370 m water depth). The reconstructed palaeoceanographic allowed for identification diverse circulation patterns, which potentially influenced life demise...
Cova del Drac, situated on Mallorca Island, is one of the most frequented caves in Europe. During late 19th century, pioneering explorers developed initial naturalistic expeditions and topographic studies. Nevertheless, it was not until period between 1922 1935 that adaptation work developed, leading to establishment permanent pathways, including installation first lighting system. The two speleothems presented this study were growing beyond these anthropogenic structures allowing a...
Mediterranean thermohaline circulation is a very sensitive system to changes in regional climate conditions. The current warming conditions have already been transferred into the deep water properties, and future projections indicate an overall weakening of this system. In context, it becomes extremely relevant understanding natural range variability interplay between different basins sub-basins controlling intermediate convection Sea. Here we use past record as laboratory learn on impact...
Speleothems are distinctive carbonate deposits found in caves, used to reconstruct hydrological variability and provide valuable paleoclimate records. Nonetheless, the interpretation of their geochemical proxies becomes a considerable challenge.La Cova del Drac, situated on Mallorca Island, is one most frequented caves Europe.

Abstract. A new high resolution deglacial and Holocene Sea Surface Temperature (SST) reconstruction is presented for the Alboran (western Mediterranean), based on Mg / Ca ratios measured in planktonic foraminifera Globigerina bulloides. This record evaluated by comparison with other Ca–SST previously published alkenone–SST reconstructions from same region both glacial period. In all cases there a degree of coherence between different records but strong discrepancies when compared to records....
