Wasps (Insecta: Vespida=Hymenoptera) from the Early Cretaceous of Spain.
Wasps and their relatives from the Lower Cretaceous lithographic limestones of Spain have been studied. Thirty specimens representing 30 species (4 of them with undetermined placement), at least 21 genera and 11 families ...
Combining fiber optic DTS, cross-hole ERT and time-lapse induction logging to characterize and monitor a coastal aquifer
The characterization of saline water intrusion (SWI) and its hydrodynamics is a key issue to understand submarine groundwater discharge (SGD) and manage groundwater resources in coastal areas. To test and compare different ...
Incorporating nutrients as a limiting factor in carbonate modelling
Nowadays, the use of process-based numerical models to predict facies distribution and stratal architecture constitutes an essential tool in sedimentary basin analysis. One of these models, the SIMSAFADIM-CLASTIC program, ...
La influencia de la sedimentación sintectónica en la geometría y cinemática de pliegues de despegue contractivos
La deformación contractiva en cinturones de pliegues y cabalgamientos despegados en sal se caracteriza por estrechos anticlinales con núcleo salino separados por anchos sinclinales de fondo plano. Su distribución y geometría ...
Magnetotelluric applied to deep geothermal exploration:Canary Islands
<p>Hoy día existe un interés creciente por la energía geotérmica, debido en gran parte al impulso de las energías renovables. La geotermia destinada a la generación de electricidad suele corresponder a reservorios profundos, ...
Seagrasses provide a novel ecosystem service by trapping marine plastics
There is strong evidence that the seafloor constitutes a final sink for plastics from land sources. There is also evidence that part of the plastics lying on the shallow seafloor are washed up back to the shoreline. However, ...
Tidal versus fluvial point bars: Key features from the integration of outcrop core and wireline log information of Triassic examples
The Triassic red beds of the Tabular Cover of the Iberian Meseta are an excellent reservoir outcrop analogue, a direct consequence of high-quality exposures, which offer exceptional three-dimensional outcrops, as well as ...
Extreme Mesozoic crustal thinning in the Eastern Iberia margin: The example of the Columbrets Basin (Valencia Trough)
Eastern Iberia preserves a complex succession of Mesozoic rifts partly or completely inverted during the Late Cretaceous and Cenozoic in relation with Africa-Eurasia convergence. Notably, the Valencia Trough, classically ...
First report of silicified wood from a late Pennsylvanian intramontane basin in the Pyrenees: systematic affinities and palaeoecological implications.
The first anatomically preserved wood specimensof an upland Carboniferous flora from the Iberian Peninsulaare reported from the Erillcastell Basin (Eastern Pyrenees,Catalonia, Spain). Two taxa are described, a calamitace ...
Climate change facilitated the early colonization of the Azores Archipelago during medieval times
Humans have made such dramatic and permanent changes to Earth's landscapes that much of it is now substantially and irreversibly altered from its preanthropogenic state. Remote islands, until recently isolated from humans, ...
Point Cloud Stacking: A Workflow to Enhance 3D Monitoring Capabilities Using Time-Lapse Cameras
The emerging use of photogrammetric point clouds in three-dimensional (3D) monitoring processes has revealed some constraints with respect to the use of LiDAR point clouds. Oftentimes, point clouds (PC) obtained by time-lapse ...
Early Cretaceous charophytes from South Dobrogea (Romania). Biostratigraphy and palaeobiogeography.
Eleven boreholes and one outcrop of the Lower Cretaceous in South Dobrogea (south-eastern Romania) were sampled for charophytes. Twenty species are described and illustrated in two non-marine rock units, the Zăvoaia Member ...
The MARCONI-3 deep seismic reflection profile: structure of the north Pyrenean foreland at the eastern part of the Bay of Biscay
The MARCONI-3 profile denotes that the structure of the North Pyrenean foreland at the western part of the Parentis Basin consists of a wedge of uppermost Cretaceous to Cenozoic synorogenic sediments lying on the top of a ...
On the termination of deep-sea fan channels: Examples from the Rhone Fan (Gulf of Lion, Western Mediterranean Sea)
The termination of a deep-sea turbiditic channel represents the ultimate sink of terrigenous sediment in the oceans or lakes. Such environment is characterized by rapid slope decrease and by loss of confinement of turbidity ...
Cross-validation of the MEDEAS energy-economy-environment model in comparison to the Integrated MARKAL-EFOM System (TIMES) and the Long-range Energy Alternatives Planning system (LEAP)
In the present study, we compare energy transition scenarios from a new set of integrated assessment models, the suite of MEDEAS models, based on a systems dynamic modeling approach, with scenarios from two already well ...
Rasgos del Micromodelado periglaciar actual sobre zonas graníticas de los Pirineos españoles (Panticosa, Huesca y Cavaller, Lleida)
El objeto de nuestro trabajo es el estudio del micromodelado desarrollado sobre granito y su evolución postglacial en dos áreas de los Pirineos Españoles: Panticosa (valle del río Gállego) y Cavallers (valle del río Koguera ...
Prospección sísmica en el Glaciar Johnsons, Isla Livingston (Antártida). (campañas antárticas 1996-1997 y 1997-1998)
Durante las campañas antárticas de 1996-97 y 1997-98, se realizaron en el glaciar Johnsons (Isla Livingston, A n t á rtida) cinco perfiles sísmicos de refracción (con un total de 2.685 m longitud) y dos perfiles de reflexión ...
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 ...
El potencial espontáneo como herramienta para la caracterización de la afección por hidrocarburos
