Freshening of the Mediterranean Salt Giant: controversies and certainties around the terminal (Upper Gypsum and Lago-Mare) phases of the Messinian Sa…

2021

The late Miocene evolution of the Mediterranean Basin is characterized by major changes in connectivity, climate and tectonic activity resulting in unprecedented environmental and ecological disruptions. During the Messinian Salinity Crisis (MSC, 5.97-5.33 Ma) this culminated in most scenarios first in the precipitation of gypsum around the Mediterranean margins (Stage 1, 5.97-5.60 Ma) and subsequently > 2 km of halite on the basin floor, which formed the so-called Mediterranean Salt Giant (Stage 2, 5.60-5.55 Ma). The final MSC Stage 3, however, was characterized by a "low-salinity crisis", when a second calcium-sulfate unit (Upper Gypsum; substage 3.1, 5.55-5.42 Ma) showing (bio)geochemica…

Ages and stratigraphical architecture of late Miocene deposits in the Lorca Basin (Betics, SE Spain): New insights for the salinity crisis in margina…

2020

International audience; Unlike most Neogene basins of the Betic Cordillera where the Salinity Crisis is dated to the Messinian, a contradictory Tortonian dating was proposed for evaporites of the Lorca Basin. As a consequence, complex structural models have been proposed in the literature to explain this discrepancy in the timing of evaporites. In order to integrate the Lorca Basin into the geological context of the western Mediterranean domain during the Late Miocene, new sedimentological and stratigraphical studies coupled with new dating were performed, which allow us to propose a Messinian age for both diatomite-bearing deposits and evaporites of the Lorca Basin. These new ages challeng…

The end of the Messinian Salinity Crisis in the western Mediterranean: insights from the carbonate platforms of south-eastern Spain.

2010

International audience; How the Messinian Salinity Crisis (MSC) ended is still a matter of intense debate. The Terminal Carbonate Complex (TCC) is a late Messinian carbonate platform system that recorded western Mediterranean hydrological changes from the final stages of evaporite deposition till the advent of Lago-Mare fresh- to brackish water conditions at the very end of Messinian times. A multidisciplinary study has been carried out in three localities in south-eastern Spain to reconstruct the history of TCC platforms and elucidate their significance in the MSC. Overall, this study provides evidence that the TCC formed following a regional 4th order water level rise and fall concomitant…

Mediterranean Movements and Constituent Political Spaces: An Interview with Sandro Mezzadra and Toni Negri

2017

These conversations between Toni Negri and Sandro Mezzadra (November 2014-october 2015) focus on the politics of Mediterranena boundaries and situate migratory movements across the Mediterranean in the geopolitical context of the Eastern and Southern shore. Looking at the proliferation of wars around the Mediterranean region and reflecting on the legacy of the Arab Uprisings, Mezzadra adn Negri revisit the concept of the "autonomy of migration" and critically interrogate its possible contribution to the field of migration and in terms of the current refugee crisis.

The economic crisis in an industrial district and its effects on the migration flows

2013

El modelo económico de la provincia de Castellón, basado en la industria cerámica (más del 90% de la producción española) y la construcción, junto con las actividades relacionadas con el turismo, la agricultura intensiva de regadío y el servicio doméstico, generó una oferta de empleo impresionante que, entre 2000 y 2007, atrajo a miles de inmigrantes, la mayoría procedentes de Rumania. La actual crisis económica ha tenido efectos devastadores en esta provincia, donde la destrucción de puestos de trabajo ha sido mucho más intensa que en el conjunto estatal, al tiempo que el paro registra niveles más altos, sobre todo entre la población extranjera. El objetivo de este trabajo es analizar el i…

Loopholes in the Echo Chambers: How the Echo Chamber Metaphor Oversimplifies the Effects of Information Gateways on Opinion Expression

2021

Social media (SM) are often regarded drivers of personalized echo chambers in which only ideas resonante that individuals already hold, leading to more extreme opinions and intensified opinion expression. However, recent theorizing and evidence has cast doubts on the universal applicability of the echo chamber metaphor, pointing out that communication effects on opinion expression are much more complex than the metaphor suggests. Using the refugee crisis in Germany as a background, the current study challenges four implicit premises of the echo chamber metaphor empirically. The findings show a more complex picture than the metaphor implies: (1) Ignoring other information sources beyond SM m…

Impact of the refugee crisis in the EU CSDP. Reference to the Spanish contribution

2015

For the last three years the EU has been facing a refugee crisis which adds on to the flux of immigrants heading to Europe. The absence of safe and legal routes results in both immigrants and refugees having to recur to traffic mafias in order to cross the Mediterranean (through two main routes, the central one from Libya and the eastern one from Turkey), which ends up turning into a pit for thousands of deaths. The EU has launched a dispositive to fight against this situation, specifically in the route that stems from Libya, the operation EUNAVFOR MED. However, its features raise a series of problems which the Security Council’s Resolution 2240 (2015) has yet to resolve.
