The role of climate, marine influence and sedimentation rates in late-Holocene estuarine evolution (SW Portugal)
Estuaries are sensitive to changes in global to regional sea level, to climate-driven variation in rainfall and to fluvial discharge. In this study, we use source and environmentally sensitive proxies together with radiocarbon dating to examine a 7-m-thick sedimentary record from the Sado estuary accumulated throughout the last 3.6 kyr. The lithofacies, geochemistry and diatom assemblages in the sediments accumulated between 3570 and 3240 cal. BP…
Holocene sea level and climate interactions on wet dune slack evolution in SW Portugal
We examine the Holocene environmental changes in a wet dune slack of the Portuguese coast, Poço do Barbarroxa de Baixo. Lithology, organic matter, biological proxies and high-resolution chronology provide estimations of sediment accumulation rates and changes in environmental conditions in relation to sea-level change and climate variability during the Holocene. Results show that the wet dune slack was formed 7.5 cal. ka BP, contemporaneous with …
The AD 1755 tsunami deposits onshore and offshore of Algarve (south Portugal)
Onshore tsunami sediment transport mechanisms inferred from heavy mineral assemblages
The aim of this study is to discuss and to extend the characterization of (palaeo)tsunami deposits, and their source materials, based upon the detailed study of their heavy mineral assemblages. Results obtained from three distinct locations (Portugal, Scotland and Indonesia), different coastal contexts and chronologies (the tsunami events studied took place at 1500 cal. yr BP, AD 1755 and 2004) are summarized and discussed in order to contribute …
Modelação geológica do enchimento sedimentar Plisto-Holocénico da paleolaguna da Pederneira
A reconstrução paleoambiental das zonas húmidas litorais portuguesas constitui um elemento fundamental para o conhecimento da história evolutiva da zona costeira num passado geológico recente (Quaternário). Com a intenção de contribuir para o melhoramento do modelo de evolução da várzea da Nazaré (paleolaguna da Pederneira) durante o Plistocénico final e o Holocénico, procedeu-se à determinação da geometria e volumetria das unidades constituintes…
Environmental evolution of the Mira estuary (SW Portuguese coast) in the Late Quaternary
A tsunami record in the sedimentary archive of the central Algarve coast, Portugal
This study describes sedimentation associated with the tsunami generated by the Lisbon earthquake of ad 1755. It is argued here that the tsunami deposited a sand sheet across the Lagoa dos Salgados (central Algarve, Portugal), that is intercalated with late-Holocene estuarine/lagoonal sediments. A wide range of proxies (sedimentological, exoscopic and palaeontological) are used to establish the provenance of the sandy material as well as to const…
La ocupación paleolítica del Alentejo meridional
El proyecto de prospección de la cuenca del río Sado (SRDS), llevado a cabo entre el 2004 y el 2008, se diseñó para suplir la carencia de información concerniente al conocimiento actual de la Prehistoria de Portugal. Aunque la cuenca del río Sado conforma casi un tercio de la superficie continental de Portugal, aún no había recibido la debida atención para el Paleolítico. Antes de este proyecto, prácticamente nada se conocía acerca de la Prehisto…
Comparing historic records of storm frequency and the North Atlantic Oscillation (NAO) chronology for the Azores region
The storminess of the Azores region was investigated using newspaper records from AD 1836 onwards. The information obtained was rank-ordered for intensity and the time series of storm frequency analysed for interannual- to century-scale variability. The documentary data set was validated by comparison with objective cyclones intensity for the period AD 1958—2000. Results indicate that four periods of contrasting storm frequency are present (AD 18…
Lateglacial and Holocene environmental changes in Portuguese coastal lagoons 1
The sedimentological and geochemical study of a core corresponding to sedimentation in the Santo André lowland since 14 000 BP allowed the reconstruction of environmental changes of this area and discussion of the relative importance of local versus global forcing factors responsible for its evolution. The pre-Holocene section of the core represents terrestrial sedimentation in a fluviatile environment, contemporaneous of a low sea level and a di…
Separating eustatic from local environmental effects
Diatom and sedimentological analyses of a 7.6-m core of the Albufeira coastal lagoon, western Portugal, provide information about the forcing factors and environmental history of the evolution of this lagoon during the last 2500 years. At this timescale, eustasy is considered to be a minor environmental control on the dynamics of the barrier-lagoonal system. Instead, these dynamics are forced by local factors, such as changes in the sand-barrier …
Tsunami sedimentation associated with the Lisbon earthquake of 1 November AD 1755
A description is given of a distinctive marine deposit at Boca do Rio on the Algarve coast of Portugal. It is proposed here that the sediment accumulation was deposited by the tsunami generated by the Lisbon earthquake of 1 November, AD 1755. The deposit exhibits sedimentary characteristics quite unlike other coastal sediment accumulations that are deposited by more moderate wave régimes. These include laterally continuous sand layers, chaotic pe…
