Holocene glacial evolution in Quingaussarsuaq Peninsula (Central–West Greenland)
The Greenland Ice Sheet (GrIS) is a key component of the global climate system, and constraining the Holocene deglaciation history of its land-terminating margins is key to understanding its sensitivity to climate forcing. Here, we provide insights into landscape evolution and environmental change on the Qinguassarsuaq Peninsula, Central–West Greenland 69°N, 50°W, where we used high-resolution geomorphological surveys and extensive field mapping …
Sedimentary indicators of anthropogenic impact in Fildes Peninsula lakes (King George Island, Maritime Antarctica)
Understanding the fluvial capture of the Guadix-Baza Basin in SE Spain through its oldest exorheic deposits
The fluvial capture of endorheic basins represents a milestone in basin chronology, implying a profound disequilibrium that triggers critical geomorphological, sedimentological, paleogeographic, and even paleoecological transformations. The primary goal of many geomorphological studies is to determine the timing of endorheic-to-exorheic transitions with the objective of unveiling the dynamics that follow the capture event. The age of the Guadix-B…
Holocene glacial oscillations in the Tyroler Valley ( NE Greenland)
Although the spatiotemporal oscillations of the Greenland Ice Sheet (GrIS) during the last millennia have played a prominent role in global environmental changes, its glacial response to the natural variability still needs to be better constrained. Here, we focused on the reconstruction of the glacial behavior and deglaciation process along the Tyroler Valley (74° N, 22° E), within the Northeast Greenland National Park. This NW‐SE valley connects…
Modern Analogue Approach Applied to High-Resolution Varved Sediments—A Synthesis for Lake Montcortès (Central Pyrenees)
In Quaternary paleosciences, the rationale behind analogical inference presupposes that former processes can be explained by causes operating now, although their intensity and rates can vary through time. In this paper we synthesised the results of different modern analogue studies performed in a varved lake. We discuss their potential value to obtain best results from high resolution past records. Different biogeochemical contemporary processes …
Humid and cold periods in the last 5600 years in Arid Central Asia revealed by palynology of Picea schrenkiana from Issyk-Kul
Central Asia, with its high mountains, despite its location between Europe and eastern Asia remains a data poor area. However, mountain glaciers are strongly affected by global change and have a wide-ranging impact. A new pollen record over the last 5600 years shows the extension of a dry Artemisia steppe around Lake Issyk-Kul, with a slightly wetter period from 4.5 to 2.7 ka BP (less Ephedra). Picea schrenkiana forest growing on north-facing slo…
A Continuous Palynological Record of Forest Clearing at Rano Kao (Easter Island, SE Pacific) During the Last Millennium
Easter Island (Rapa Nui) deforestation has traditionally been viewed as a single event, synchronous in time and space across the island and caused by Polynesian settlers. However, recent studies have challenged this idea, introducing the concept of spatiotemporal heterogeneity and suggesting a role for climate change. This paper presents a continuous paleovegetation record of the last millennium (~960 to ~1710 CE), based on palynological analysis…
The deglaciation of Barton Peninsula (King George Island, South Shetland Islands, Antarctica) based on geomorphological evidence and lacustrine records
Barton Peninsula is an ice-free area located in the southwest corner of King George Island (South Shetland Islands, Antarctica). Following the Last Glacial Maximum, several geomorphological features developed in newly exposed ice-free terrain and their distribution provide insights about past environmental evolution of the area. Three moraine systems are indicative of three main glacial phases within the long-term glacial retreat, which also favo…
Revisiting the role of high‐energy Pacific events in the environmental and cultural history of Easter Island (Rapa Nui)
Pacific islands are spread over thousands of kilometres of the Pacific Basin and are characterised by similar ecological features but very diverse geologic origins, from steep volcanoes to flat coral atolls. Several climatic phases have been shared across the region within the last 1,000 years. Numerous and abrupt societal and cultural changes during the same period have been described for islands separated by thousands of kilometres. Conspicuous…
Lateglacial to Early Holocene recursive aridity events in the SE Mediterranean Iberian Peninsula
Karst landscape evolution in the littoral area of the Bay of Biscay (north Iberian Peninsula)
Climate, palaeohydrology and land use change in the Central Iberian Range over the last 1.6 kyr
A multiproxy study of a 7 m long sedimentary sequence from Lake La Parra (39°50.948′, 1°52′, 1014 m a.s.l.) supported by 11 14 C AMS and 210 Pb/ 137 Cs dates provides a robust, high-resolution hydrological and environmental variability record for the last 1600 years of the Las Torcas sinkhole Complex in the Central Iberian Range. The succession of depositional environments in Lake La Parra sinkhole is controlled by both changes in the regional wa…
An 8700-year record of the interplay of environmental and human drivers in the development of the southern Gran Sabana landscape, SE Venezuela
The vegetation of the southern Gran Sabana (SE Venezuela) consists primarily of a treeless savanna with morichales ( Mauritia flexuosa palm stands), despite the prevailing climate being more favorable for the development of extensive rainforests. Here, we discuss the results of our 8700-year paleoecological reconstruction from Lake Encantada based on the analysis of pollen, algal remains, charcoal, and geochemical proxies. We use the findings to …
Climate imprints during the ‘Medieval Climate Anomaly’ and the ‘Little Ice Age’ in marine records from the Alboran Sea basin
An integrated multiproxy analysis from westernmost Mediterranean hemipelagic sediments has provided further insights into natural climate variability and forcing mechanisms in this region during the last two millennia. Two deep-sea marine records, with a robust age model provided by the activity–depth profiles of 210 Pb and 137 Cs, together with 14 C dating, allowed us to perform a detailed reconstruction of paleoenvironmental and paleoceanograph…
Integrated Archaeozoological Research of Shell Middens
Shells of Nacella magellanica are abundant in archaeological shell middens distributed along the Beagle Channel. In this study we analyzed the oxygen isotopic composition of shells of this species to obtain information on its seasonal exploitation patterns by hunter-gatherer-fisher groups in this region during the nineteenth century. Oxygen isotopic data from shells recovered from Lanashuaia and from some occupations of Túnel VII (both contact si…

Cette séquence est datée par les méthodes de l'Uranium et du C-14 entre 35 et 60 ka BP. Les niveaux archéologiques foui…
