Marine terrace staircases of western Iberia: Uplift rate patterns from rocky li...
Martins, António; Gouveia, Margarida; Cunha, Pedro; Cabral, João; Gomes, Alberto; Falguères, Christophe Falguères; Voinchet, Pierre; Stokes, MartinThe Western Iberian Peninsula is undergoing compressive tectonic reactivation, resulting in spatial and temporal variations of surface uplift. Uplift quantification can be undertaken in coastal settings using staircases of shore platforms developed onto rocky headlands. This study analyses two marine terrace staircases in central Portugal: Cape Raso - Abano beach and Cape Espichel. Geomorphic and stratigraphic ...
Plio-Quaternary coastal uplift along the western Iberian Margin: insights from ...
Gouveia, Margarida; Cunha, Pedro; Martins, António; Stokes, Martin; Gomes, Alberto; Falguères, Christophe; Voinchet, Pierre; Jacques Bahain, JeanThis study presents a detailed geomorphological and geochronological analysis of a marine terrace staircase developed into the Peniche Peninsula (Portugal), a rocky headland of Jurassic carbonate bedrock located in the central sector of the Western Iberian passive margin. The marine terrace levels are described morphologically and sedimentologically, but also dated using ESR and U-Series methodologies. The mari...
Spatiotemporal analysis of mosquito-borne infections and mosquito vectors in ma...
Moutinho, Sandra; Rocha, Jorge; Gomes, Alberto; Gomes, Bernardo; Ribeiro, Ana IsabelBackground The incidence of mosquito-borne infections has increased worldwide. Mainland Portugal’s characteristics might favour the (re)emergence of mosquito-borne diseases. This study aimed to characterize the spatial distribution of vectors and notification rates of imported cases of mosquito-borne infections in mainland Portugal and demarcate the areas where these geographies overlap. Methods We used data fr...
The endorheic – Exorheic transition and later stage of fluvial incision in a we...
Freitas, Marcelo; Paixão, Rodrigo; Salgado, André; Silva, Luis; Cunha, Pedro; Gomes, Alberto; Martins, António; Almeida, Júlio; Tupinamba, MiguelPresent-day endorheic drainage systems are rare in tropical humid regions and/or close to the coast. During the late Cenozoic, under a humid tropical climate, the Paraíba do Sul River basin (SE Brazil) has developed along the South America passive margin. This basin currently drains into the South Atlantic Ocean, but it preserves landforms that are indicative of previous endorheic paleodrainage. This study exam...
Iberia: insights from the Lower Mondego River terraces (central Portugal)
Martins, António; Cunha, Pedro; Gouveia, Margarida; Gomes, Alberto; Falguères, Christophe; Stokes, Martin; Voinchet, Pierre; Cabral, JoãoThe Lower Mondego Valley (LMV), located in the Western Iberian passive margin which is under compressive tectonic reactivation since ca. 80 Ma, is used for deciphering long-term landscape evolution during the Quaternary and the control played by active tectonics, eustasy and climate. The elaboration of a detailed geomorphological map allowed the establishment of the spatial and temporal distribution of the diff...

Martins, António; Gouveia, Margarida Porto; Cunha, Pedro Proença; Gomes, Alberto; Falguères, Christophe; Voinchet, Pierre; Stokes, MartinThe Western Iberian passive margin is under compressive tectonic reactivation resulting in spatial and temporal variations in surface uplift. This uplift can be quantified in coastal settings using staircases of wave-cut platforms developed onto rocky headlands. This study focuses on two marine terrace staircases of central Portugal: Cape Raso (west of Lisbon) and Cape Espichel (western Arrábida mountain chain)...

Gouveia, Margarida; Cunha, Pedro; Martins, António; Falguères, Christophe; Voinche, Pierre; Gomes, Alberto; Bahain, Jean-Jacques; Stokes, MartinThis study provides a detailed geomorphological study of the Peniche Peninsula, located in westernmost Iberia, a resistant rocky limestone headland subjected to high energy Atlantic Ocean coastal processes. We have used field mapping, surveying, sedimentary facies analysis, geochronology (electron spin resonance [ESR]; U-Series), but also identification of fossils and lithic artefacts, in order to: 1) reconstru...
Spatial variations in sediment production and surface transformations in subtro...
Cruz, Armanda Trindade; Dinis, Pedro Alexandre; Lucic, Mavro; Gomes, AlbertoSeveral compositional features of sedimentary deposits can be used to reconstruct environmental conditions of source areas. In this research, bulk X-ray diffraction mineralogy, heavy and clay mineral assemblages and geochemistry obtained for modern deposits of the Cunene River and its tributaries Caculuvar–Mucope are integrated with geological/geomorphological characteristics of respective catchment areas to ev...

Cunha, Lúcio; Nunes, Adélia; Dimuccio, Luca; Paiva, Isabel; Figueiredo, Rui; Figueiredo, Albano; Vieira, António; Gomes, Alberto; Forte, JoãoPor decisão das estruturas diretivas da IAG (Associação Internacional de Geomorfólogos) tomada na Índia, em 2017, aquando da realização da IX Conferência Internacional de Geomor fologia, a Conferência Internacional seguinte seria realizada em Portugal, mais exatamente na cidade de Coimbra, no ano de 2021. Fomos contactados para o efeito e aceitámos este desafio que se antevia complexo e difícil, mas que sabíamo...
