Holocene climate dynamics on the European scale
Évolution des parasitoses entre les populations mésolithiques et néolithiques
Le processus de néolithisation a contribué à transformer nos relations avec les agents pathogènes. La sédentarisation, la domestication, la mise en présence sur le même espace de différentes espèces ainsi que leurs gestions sont autant de comportements qui ont contribué à modifier nos contacts vis-à-vis des zoonoses, dont les parasitoses. Ces modifications ont impacté les relations hôtes/parasites. L’analyse paléoparasitologique de la Lède du Gur…
Human settlement and landscape dynamics on the coastline south of the Gironde estuary (SW France)
The Gironde estuary in SW France is the largest in Western Europe and has attracted human populations since prehistoric times. From the 1970s to the 1990s, intense archaeological research was undertaken on the long and highly dynamic coastline just south of the estuary mouth. In recent years, the combined action of increased coastal erosion and human pressure has proved a serious threat to the integrity of archaeological sites in the area. As a c…
Les sociétés littorales et leur environnement
Dans le nord du Médoc (Gironde), entre les communes de Soulac-sur-Mer et Montalivet-les-Bains, le littoral sableux est soumis à une très forte érosion. Face à un riche patrimoine archéologique, historique et paléoenvironnemental, une équipe interdisciplinaire a été constituée, regroupant archéologues, géomorphologues et biologistes. Les opérations de terrain réalisées dans des contraintes extrêmement fortes ont nécessité la mise en place d'un pro…
Fouiller sur l’estran
Sur estran, les vestiges apparaissent très bien conservés et parfois même immédiatement apparents lors de périodes d’érosion. Mais les contraintes s’accumulent à tous les niveaux : temps d’intervention limité, présence de l’eau, alternance des marées, rapidité de l’érosion dans certains secteurs, conditions d’accès ou de fouille, difficulté de mise en place d’infrastructures lourdes. Pour ces raisons, les interventions sur cet espace sont longtem…
Humans and their environment on the Médoc coastline from the Mesolithic to the roman period
The northern coast of the Médoc between Soulac-sur-Mer and Montalivet-les-Bains has a rich archaeological heritage that is being directly impacted by coastal erosion. A series of clay-peat palaeosols that formed in ancient estuarine marshes holds evidence of intensive occupation from the Mesolithic until the end of the Roman period. Within this framework, our research focused on the two key sites of La Lède du Gurp (Grayan-et-l’Hôpital) and L’Amé…
Onshore and offshore evidences for four abrupt “warming” episodes during MIS 6 at the westernmost tip of continental Europe
Millennial-scale Holocene hydrological changes in the northeast Atlantic
A mid- to late-Holocene paleohydrological reconstruction from the northeast Atlantic is proposed through the study of a high-resolution sedimentary record from the northern continental shelf of the Bay of Biscay (BoB). Three foraminiferal species dominate the assemblages with Rosalina globularis showing an overall decrease in absolute and relative abundances from ~7 to 0.4 cal. ka BP, whereas the opposite trend is observed for Cibicides refulgens…
High frequency environmental changes and deposition processes in a 2 kyr-long sedimentological record from the Cap-Breton canyon (Bay of Biscay)
The core MD03-2693 (43°39.258′N; 01°39.805′W; 431 m water depth) was collected on an abandoned meander of the Capbreton Canyon (SE Bay of Biscay), filled over the last millennia by very high sedimentation rates (mean sedimentation rate of 1.2 cm/yr) linked to its specific environmental location and fine-grained clayed sediment decantation from the proximal canyon axis. This archive thus permits to undertake the study of late Holocene regional cli…
The impact of African aridity on the isotopic signature of Atlantic deep waters across the Middle Pleistocene Transition
A high resolution analysis of benthic foraminifera as well as of aeolian terrigenous proxies extracted from a 37 m-long marine core located off the Mauritanian margin spanning the last ~ 1.2 Ma, documents the possible link between major continental environmental changes with a shift in the isotopic signature of deep waters around 1.0–0.9 Ma, within the so-called Mid-Pleistocene Transition (MPT) time period. The increase in the oxygen isotopic com…
Atlantic suboreal paleoenvironments during Marine Isotopic Stage 3
Low-latitude “dusty events” vs. high-latitude “icy Heinrich Events”
It has been proposed that tropical events could have participated in the triggering of the classic, high-latitude, iceberg-discharge Heinrich events (HE). We explore low-latitude Heinrich events equivalents at high resolution, in a piston core recovered from the tropical north-western African margin. They are characterized by an increase of total dust, lacustrine diatoms and fibrous lacustrine clay minerals. Thus, low-latitude events clearly refl…
European Climatic Response to Millennial-Scale Changes in the Atmosphere–Ocean System during the Last Glacial Period
Pollen, foraminifer, dinocyst, and coarse lithic high-resolution analyses and δ 18 O measurements have been carried out for the last-glacial section of marine core MD95-2042 located near the southwestern margin of the Iberian Peninsula. The pollen data indicate a high frequency of vegetational changes on the adjacent continent during this period, suggesting a climatic variability very similar to that of the Dansgaard-Oeschger cycles recorded by t…
