Temporal and Spatial Variations of Secchi Depth and Diffuse Attenuation Coefficient from Sentinel-2 MSI over a Large Reservoir

Gonçalo Rodrigues, Miguel Potes, Maria João Costa, Maria Helena Novais, Alexandra Marchã Penha, Rui Salgado, Maria Manuela Morais The Alqueva reservoir (South of Portugal) in the Guadiana river basin constitutes the most important water resource in southern Portugal for domestic and agricultural consumption. We present a methodology developed to characterize spatial and temporal variations of ...

Benthic diatom community dynamics in Mediterranean intermittent streams: Effects of water availability and their potential as indicators of dry-phase ecological status

Maria Helena Novais, Eduardo A. Morales, Alexandra Marchã Penha, Miguel Potes, Agnès Bouchez, Amélie Barthès, Maria João Costa, Rui Salgado, Jorge Santos, Manuela Morais. Benthic diatom community dynamics in Mediterranean intermittent streams: Effects of water availability and their potential as indicators of dry-phase ecological status. The study of intermittent rivers is a critical and timely issue due to their worldwide increase, triggered by several causes ...

Prasinophyte bloom and putative fungi abundance near the Kačák event (Middle Devonian) from the Odivelas Limestone, Southwest Iberia

Gil Machado, Ladislav Slavík, Noel Moreira, Paulo Emanuel Fonseca Prasinophyte bloom and putative fungi abundance near the Kačák event (Middle Devonian) from the Odivelas Limestone, Southwest Iberia The Kačák Event is one of the several prominent Devonian climatic and biotic perturbations with a supra-regional to global extent. Its record can be traced in the litho- and biostratigraphy of uppermost Eifelian-lowermost Givetian strata ...

Assessment of Geodiversity in the Southern Part of the Central Iberian Zone (Jaén Province): Usefulness for Delimiting and Managing Natural Protected Areas

A. Fernández, T. Fernández, D. I. Pereira, L. M. Nieto, Assessment of Geodiversity in the Southern Part of the Central Iberian Zone (Jaén Province): Usefulness for Delimiting and Managing Natural Protected Areas To explore the relationship between geodiversity and borders of natural protected areas, we studied the northern part of Jaén Province (southern Spain), where the southern sector of the Central Iberian ...

Best Practices and Constraints in Geopark Management: Comparative Analysis of Two Spanish UNESCO Global Geoparks

Thais S. Canesin, José Brilha, Enrique Díaz-Martínez, Best Practices and Constraints in Geopark Management: Comparative Analysis of Two Spanish UNESCO Global Geoparks Spain is an international reference for geoparks and geoconservation polices, and it is the second country in the world with the highest number of UNESCO Global Geoparks (UGGps), after China. Additionally, Spain was one of the four countries ...

The Role of UNESCO Global Geoparks in Promoting Geosciences Education for Sustainability

Maria Manuela Catana, José B. Brilha. The Role of UNESCO Global Geoparks in Promoting Geosciences Education for Sustainability. Following the establishment in 2000 of the first geoparks, the role of UNESCO Global Geoparks (UGGps) in geoscience education for sustainability needs to be characterized and understood. This is particularly relevant because education is one of the three main pillars of UGGps. ...

Numerical study of the seasonal thermal and gas regimes of the large artificial reservoir in Western Europe using LAKE2.0 model

Iakunin, M., Stepanenko, V., Salgado, R., Potes, M., Penha, A., Novais, M. H., and Rodrigues, G. The Alqueva reservoir (southeast of Portugal) being the largest artificial lake in Western Europe and strategic freshwater supply in the region is of scientific interest in terms of monitoring and maintaining the quality and quantity of water and its impact ...

Public Understanding on Geoconservation Strategies at the Passagem das Pedras Geosite, Paraíba (Brazil): Contribution to the Rio do Peixe Geopark Proposal

Wellington Francisco Sá dos Santos; Ismar de Souza Carvalho; José Brilha. The Rio do Peixe basin, which is developed during the Lower Cretaceous, consists of the Sousa, Uiraúna-Brejo das Freiras, Pombal and Vertentes sub-basins. They have abundant ichnofauna represented by dinosaur tracks of theropods, sauropods and ornithopods, these being the main objects of geological heritage in the region. The majority of palaeontological sites ...
