Holocene climate variability in the Western Mediterranean region from a deep water sediment record
The detailed analysis of the International Marine Past Global Changes Study core MD99-2343 recovered from a sediment drift at 2391 m water depth north of the island of Minorca illustrates the effects of climate variability ...
El Niño-Southern Oscillation-like variability during glacial terminations and interlatitudinal teleconnections
Interannual-decadal variability in the equatorial Pacific El Niño-Southern Oscillation (ENSO) induces climate changes at global scale, but its potential influence during past global climate change is not yet well constrained. ...
Local formation of varved sediments in a karstic collapse depression of Lake Banyoles (NE Spain)
Banyoles is the largest and deepest lake of karstic-tectonic origin in the Iberian Peninsula. The lake comprises several circular sub-basins characterized by different oxygenation conditions at their hypolimnions.The ...
Two dimensional interpretation of 3-D magnetotelluric data: an example of limitations and resolution
Interpretation of magnetotelluric (MT) data for three-dimensional (3-D) regional conductivity structures remains uncommon, and two-dimensional (2-D) models are often considered an adequate approach. In this paper we examine ...
Nota sobre la escama de corrimiento del Montsec de Tost en el Prepirineo español (prov. de Lérida)
En esta nota se estudian las reacciones tectónicas entre diversas unidades del Prepirineo español (prov. de Lrida), junto a la zona axial pirenaica. El estudio tectnico permite evidenciar el carácter alóctono de la Unidad ...
Monitoring plastic pollution using bioindicators: a global review and recommendations for marine environments
Monitoring the movement of plastic into marine food webs is central to understanding and mitigating the plastic pollution crisis. Bioindicators have been a component of the environmental monitoring toolkit for decades, but ...
Subsidence and thermal history of an inverted Late Jurassic-Early Cretaceous extensional basin (Cameros, North-central Spain) affected by very low- to low-grade metamorphism.
The Cameros Basin (North Spain) is a Late Jurassic-Early Cretaceous extensional basin, which was inverted during the Cenozoic. It underwent a remarkable thermal evolution, as indicated by the record of anomalous high ...
Evidence of recent ruptures in the central faults of the Acambay Graben (central Mexico)
The Acambay Graben, within the central part of the Trans-Mexican Volcanic Belt, is one of the major sources of continental earthquakes in Mexico. To date, the activity and paleoseismological history of the axial faults of ...
Comparison between ROV video and Agassiz trawl methods for sampling deep water fauna of submarine canyons in the Northwestern Mediterranean Sea with observations on behavioural reactions of target species
In this paper we present a comparison between Remotely Operated Vehicle (ROV) and Agassiz trawling methods for sampling deep-water fauna in three submarine canyons of the Northwestern Mediterranean Sea and describe the ...
Perillositat i gestió de les inundacions al nord del cap de Creus
[cat] Aquest article tracta de les rieres situades entre Portbou i el Port de la Selva que estan sotmeses al risc d'inundació. Són rieres on es produeixen inundacions que causen danys i pèrdues econòmiques en béns públics ...
Filling the gap in the evolution of the genus Echinochara Peck (Clavatoraceae, Charophyta)
Echinochara is a poorly known charophyte genus of the extinct family Clavatoraceae that thrived in the MiddleJurassic–Early Cretaceous of North America, Europe, and North Africa. It represents the most ancient and ...
Indicadores geomorfológicos de tsunamis históricos en las costas rocosas de Baleares
This paper summarizes the results of geological, geomorphological and morphometric analysis of 50 study areas spread between the islands of Menorca, Mallorca, Ibiza and Formentera, where large blocks appears on top of ...
Recent large earthquakes from a geophysical perspective
In recent times our society has been disturbed by the effect of various earthquakes (Haiti, Chile, New Zealand, and Japan). These are not new phenomena, the Earth has been and will be subjected to their action, but large ...
Schmidth Hammer exposure dating (SHED): Rapid age assessment of glacial landforms in the Pyrenees
Schmidt hammer (SH) sampling of 54 10Be-dated granite surfaces from the Pyrenees reveals a clear relationship between exposure and weathering through time (n=52, R 2=0.96, P<0.01) and permits the use of the SH as a numerical ...
Middle-Upper Triassic successions in the eastern Iberian Chain (Alt Palància and Manzanera areas): Stratigraphic precisions.
Cartographic, statigraphic and structural studies in the Alt Palància and Manzanera areas indicate that the Middle-Upper Triassic successions entirely belong to the 'Mediterranean type of Triassic'. The two carbonate units ...
Sediment transport along the Cap de Creus Canyon flank during a mild, wet winter
Cap de Creus Canyon (CCC) is known as a preferential conduit for particulate matter leaving the Gulf of Lion continental shelf towards the slope and the basin, particularly in winter when storms and dense shelf water ...
Magnetoestratigrafía de las sucesiones del Mioceno medio y superior del Vallés occidental (Depresión del Vallés-Penedés, NE España): Implicaciones biocronológicas y cronoestratigráficas.
The magnetostratigraphic analysis of the middle to late Miocene continental deposits from the Valles-Penedes basin, combined with its well-documented fossil mammal record, provides a well-resoluted chronology for the upper ...
Studying monogenetic volcanoes with a Terrestrial Laser Scanner: Case study at Croscat volcano (Garrotxa Volcanic Field, Spain)
Erosional processes (natural or anthropogenic) may partly destroy the relatively small-sized volcanic edifices characteristic of monogenetic volcanic zones, leaving their internal structure well exposed. Nevertheless, the ...
A review of undulated sediment features on Mediterranean prodeltas: distinguishing sediment transport structures from sediment deformation
Most Mediterranean prodeltas show undulated sediment features on the foresets of their Holocene wedges. These features have been described all along the Mediterranean for the last 30 years and interpreted as either soft ...
