the millionth map of the Quaternary of France, version 2020 is available

The Quaternary millionth map of metropolitan France proposed here presents the geological polygons of Quaternary-age formations of metropolitan France as well as certain remarkable sites (prehistoric, of climatic interest, paleontological, palynological) that have been the subject of a comprehensive study over the past 20 years.

The polygons are RGF (Geological Referential of France) labeled and the RGF chronostratigraphic charter (compatible with the INSPIRE standard) was used for the chronological attributions. The map has been updated according to recent modifications of the international stratigraphic chart.

This map will in the end be integrated into the next map of the European Quaternary at 1 / 2,500,000 (IQuaME)

The new issue of Quaternaire journal (Vol 30 No 2) has been published

Dedicated to the publications of the Q11 symposium held in Orléans in 2018, it first takes us to the Bao Bolon Valley in Senegal for a paleoenvironmental study of the second half of the Holocene (Stern et al., 2019). Back in France, in the Somme Valley, paleontological and geochronological data allow a reinterpretation of the archaeological site of Menchecourt (Bahain et al., 2019). Which large animals lived in the vicinity of the Neandertal occupations of the Ramandils cave (Port-la-Nouvelle, Aude, France)? Rush et al. (2019) study their assemblages to reconstruct the palaeoenvironmental and paleoclimatic framework during the Late Pleistocene.

Cover of Quaternaire, Volume 30 Issue 2

Two articles are devoted to the region of Orleans which hosted the Q11 symposium. Coussot et al. (2019) describe the chronostratigraphy of the filling of a palaeovallon by silt in the context of the Beauceron plateau at Courville-sur-Eure (Eure-et-Loir, France), which extends from the second half of the Middle Pleistocene to the Holocene. From a sedimentary filling section at the prehistoric site of La Roche-Cotard IV (Indre-et-Loire, France), Marquet et al. (2019) conclude that the parietal productions with a symbolic character of the cave are very probably the work of the Neanderthal Man.

Finally, Armynot of Châtelet et al. (2019) have characterized foraminifers to reconstruct the environment of the Merovingian and Carolingian emporium of Quentovic, in the mouth of the Canche (France).

You can read a more detailed introduction of this issue and the Q11 colloquium in the foreword (Tissoux and Jacob, 2019).

Death of émilie campmas

Emilie CAMPMAS (1983-2019)

Emilie passed away on Friday, March 8, 2019 after five years of tenacious struggle against this terrible disease that is cancer. After having held, from 2014 to 2016, an ATER position at the Université Toulouse Jean Jaurès, she had recently joined CNRS as a researcher at the TRACES laboratory. A relentless worker, with bulimia of knowledge, Emilie was a young researcher out of the ordinary as much for her dynamism, her scientific rigor, her sense of the collective, her so communicative enthusiasm ! Laureate of several prizes, including a L’Oréal France thesis grant for women and science in 2011 or more recently the Young Researcher Award in Prehistoric and Anthropological Archeology from SAMRA and the Award from Fondation des Treilles, she became in a few years an essential researcher enjoying full recognition in the field of expertise that was her: the adaptation to the coastal environment of Paleolithic hunters-collectors.

An archaeozoologist specialized in large fauna and malacofauna, Emilie launched her career during a Master 1 course conducted at UTAH in 2006 on the fauna from the excavation materials of cave Abri du Moulin in Troubat. Her doctorate “Characterization of the occupation of the sites of the region of Temara (Morocco) in the Upper Pleistocene and new data on the subsistence of Middle Paleolithic men of North Africa: Examples of taphonomic and archeozoological approaches carried out on the faunas of El Harhoura 2 and El Mnasra “, that she defended in 2012 at the University of Bordeaux 1, was the starting point of her problematic on coastal economies. Having demonstrated, thanks to an exemplary taphonomic study of the faunal assemblages, the decisive role of the littoral in the modalities of occupation of the territories by the Aterian and then Ibero-Amaurian human groups, her results had then brought her to be interested in the thorny issue of cultural modernity for these “archaic” populations. The early diversification of food resources, especially the consumption of marine shellfish, coupled with the presence of Nassarius sp. symbolic markers, had allowed her to draw a convincing parallel with what is observed in South Africa’s anatomically modern men, opening up new perspectives on the evolutionary trajectories of these populations and the role played by coastal environments in the emergence of so-called modern behaviors. On these issues, she co-organized two sessions: one in 2016, at the SAfA Congress “The role of North Africa in the emergence and development of modern behaviors: Integrated Approach”, the other in 2018 PANAF Congress “Diversity of hominin subsistence strategies across Africa from the Middle Pleistocene to the Holocene”.

In parallel with these major anthropological questions, the fine analysis of the bone material was at the heart of Emilie’s approach. Particularly active in the field of taphonomy with her strong involvement in the European Network for Quaternary Taphonomy, Emilie was also a field scientist. Since 2006, she was a member of the Franco-Moroccan mission “El Harhoura-Témara” and in 2016 she led an ethnographic mission on the coastal fringe of the Atlantic around Rabat-Témara to combine archaeological and ethnological data for the exploitation of marine molluscs. In order to fully discuss the complementarity of terrestrial and marine animal resources, she had expanded her areas of expertise to the field of malacology, leading her to train with Catherine Dupont and begin to develop experimental approaches on the use of mollusc shells as a butcher’s knife. Seeking to understand the diversity of coastal adaptations, she was just beginning to extend her research to the entire circummediterranean zone both in the Neanderthals of the European Pleistocene and in the fully anatomically modern humans of the late Upper Pleistocene and early Holocene in North Africa and Eurasia. During all these years, I had the chance to work with her first as a supervisor alongside Patrick Michel and then as a colleague. I salute here her courage and her scientific career so rich and intellectually stimulating. Emilie, we’ll miss you …

What future for the ice shelves in the Antarctic Peninsula?

An international research group, including scientists from three French laboratories (1), has revealed the systematic and negative impact of ocean warming on the extent of ice shelves in the East Antarctic Peninsula in recent decades and the 9000 last years.

The Antarctic Peninsula is one of the regions most affected by the current global warming. Over the last 50 years, it has lost almost 75% of the surface of its floating ice platforms, which are important barriers to ocean erosion for the continental ice cap and, therefore, limit the sea-level increase. The major collapses of these platforms in recent decades coincide systematically with joint and rapid increases in ocean temperature (+0.3°C) and atmospheric temperature (+3°C).

Location of the study sites (JPC-38, marine core, JRI, ice core) and the main glacial platforms (Larsen A, B and C). The shaded area corresponds to the area where the ocean temperature reanalyses and the simulations for the future were made (figure modified from Etourneau et al.).

Scientists conducted geochemical analysis of marine sedimentary records which were compared to data from an ice core located only 50km from their study site. With these temperature reconstructions covering the last 9000 years, they have shown that the main period during which all the platforms have been greatly reduced in the Eastern Antarctic Peninsula, between 8200 and 6000 years BC, occurred during a major oceanic warming (+1.5°C) period, while the atmosphere was cooling. They also pointed out that the progressive warming of the ocean (+0.3°C) over the last thousand years has recurrently controlled the gradual removal of the ice shelves of this region.

Based on this observation, this research team focused on assessing the possible evolution of ocean and atmospheric temperatures over the next century, based on two scenarios established by the Intergovernmental Panel on Climate Change (IPCC). Only the pessimistic scenario of increasing atmospheric (+3°C) and oceanic (+0.3°C) temperatures would be enough to weaken these ice platforms even more, until they can collapse completely in the coming decades. Their future therefore belongs henceforth to the respect or not of the Paris Agreements, and to its objectives of limiting global warming to +2°C.

extreme vulnerability of African moUNTAIN forests to climate change revealed by the sediments of a lake in Cameroon

The pollen grains content of lacustrine sediments allowed to trace the history of mountain biomes in Cameroon during the last 90 000 years. This study, conducted by French laboratories LOCEAN and LSCE of the IPSL with the National Herbarium of Cameroon, showed that tropical mountain forests are extremely vulnerable to climate change.

Bambili Lake (© A.-M. Lézine) is located on the volcanic line of Cameroon, one of the hotspots of global diversity.

Because they have forms and ornamentations that are specific to most plant species and are remarkably preserved in sediments, pollen grains are powerful tools for reconstructing the vegetation of the past and understanding biodiversity.

Bambili Lake, located on the volcanic line of Cameroon at an altitude of 2273m, has provided a unique palynological sequence in tropical Africa, the first that accurately covers such a long period, ie most of the last climatic cycle. This sequence makes it possible to precisely follow the response of mountain biomes to extreme climatic, glacial and interglacial situations.

The study shows that Cameroon’s mountain forest biome has been extremely sensitive to climate change in contrast to lowland forests that appear to have been much more stable. Its area has varied considerably over time, in particular because of the large movements of its upper limit. This ecological instability has not been a hindrance to the exceptional biodiversity of the high mountains of Cameroon, but has instead favored it.

Discovery of the oldest lead pollution in humans: 250,000 years

Analyzes performed on the teeth of two Neanderthal children from the archaeological site of Payre (Ardèche) and excavated by Marie-Hélène Moncel, CNRS researcher, attest to the oldest exposure to lead in humans. An international team of researchers measured the metal levels in the enamel of these teeth, dating back around 250,000 years, and showed that both children had been exposed to lead during their stays in cavities as suggested by the presence of lead mines within a radius of 25 kilometers. With teeth growing at the same rate as tree rings, researchers were able to show that children became ill during the cold season, and that one of the Neanderthals was born in the spring. By measuring barium concentrations, a marker of milk consumption, the researchers also found that one of the two children had been breastfed for up to two and a half years, and weaned in the fall. The study published on October 31, 2018 in Science Advances is a major contribution to Neanderthal childhood knowledge.

An explanation of the abrupt climate change cycles of the past 130,000 years

An international team(1) modeled the coupling between the extent of sea ice and marine ice shelves, and the temperature of the waters near the North Atlantic surface. This model explains the steep temperature changes in Greenland and the North Atlantic during the last ice age, between 130,000 and 15,000 years ago. It also reproduces the phase shift between the temperatures of the two hemispheres during this period, as estimated from measurements in ice cores in Greenland and Antarctica. This work should help assess the risk of such abrupt changes in the near future.

The last glacial interval was marked by abrupt climatic changes called Dansgaard-Oeschger (DO) events. These events, characterized by significant temperature increases over Greenland up to 15°C in a few decades and a return to glacial conditions over several centuries, have been repeated many times during the last glacial cycle. However, the cause of these transitions and their out-of-phase relationship with corresponding events in Antarctica remains unclear. Indeed, a satisfactory theory of the Dansgaard-Oeschger cycles was still missing.

The team built a dynamic model to explain these DO events in Greenland, but also their counterparts observed in Antarctica. This model focuses on the interactions between ice sheets from the northern hemisphere ice caps (and more specifically Greenland), sea ice and ocean currents. It demonstrates that the repetitive nature and speed of the warming phase of DO events is based on the rapid retreat and slower regeneration of thick marine ice platforms, several hundred meters, and the much thiner sea ice, only a few meters around the caps of the northern hemisphere.

Variability of the last glacial interval as expressed by changes in oxygen isotope ratio (18O) obtained from two ice cores: blue in Greenland (NGRIP-North GReenland ice core project) and orange in Antarctica (WAIS ice core – West Antarctic ice sheet divide project). Age in thousands of years before the year 2000.

The proposed model successfully replicates the observed characteristics of changes in the oxygen isotope ratio, such as the sawtooth form of DO cycles (with sudden warming and slower cooling to glacier conditions), the intervals between successive DOs during the last 130 000 years, and also the phase shift of the climate signal observed in the ice cores of Greenland and Antarctica: when Greenland warmed, Antarctica cooled, and conversely, the abrupt warmings observed in Greenland not having their counterparts in Antarctica.

In addition, this study provides an explanation for abrupt climate changes and could thus help to more accurately assess the risk of abrupt climate transitions in the near future.

Call for papers for papers for the journal Méditerranée : “Littoral Landscapes: Evolution and Risk of Erosion of Heritage”

Call for papers for a special issue of the journal Méditerranée entitled “Coastal landscapes: evolution and risk of heritage erosion” (issue coordinators: Benoît Devillers, Pau Olmos Benlloch and Père Castanyer).

One of the forgotten planning policies related to the current retreat of the shorelines is the erosion of the natural, archaeological and geomorphological Heritage. At the European scale, several initiatives have highlighted the vulnerability of heritage to the effects of climate change and human pressure. The conservation and mediation of this fragile heritage are actual challenges. The protection of the archaeological heritage of the coastal area is lagging far behind marine and especially continental areas. The reasons are many: difficulty of excavations, high erosion rate, lack of definition of administrative skills and very strong land pressure.

Currently, several European research teams are working on coastal erosion and archaeological heritage, particularly on the Atlantic seaboard: ALeRT project (UMR 6566 CReAAH Rennes); Litaq (Ausonius, Bordeaux); SCHARP (University of Saint Andrews, Scotland); CITiZAN (Museum of London Archeology, England); Bregantia (INCIPIT, Galicia, Spain); MASC project (Institute of Technology Sligo, Ireland). The main results were presented at international conferences such as the Homer symposium (Vannes, Brittany, 2011), the Weather Beaten Archeology (Sligo, Ireland, 2015) conferences or during specific sessions in the symposium of the European Association of Archaeologists (EAA) (Helsinki, 2012 and Glasgow, 2015) or Landscape Archeology Conference (Uppsala, 2016).

The various works carried out in the Atlantic facade show the need for projects to inventory and monitor site erosion. Storm episodes in recent years (2010, 2014) have accelerated the process of destruction and discovery of archaeological sites. In the Mediterranean, the situation is different, the climatic events are less violent, but there is a slow and gradual erosion, particularly in relation with the urbanization of the coasts. However, there are exceptions where sea-level rise, over-spells and anthropogenic pressure are accelerating the process of coastal erosion and destruction of archaeological heritage, as is the case of Kerkennah archipelago in Tunisia.

On the east and central Mediterranean coast, other initiatives have emerged, notably the project “Noé cartodata: carte de risque du patrimoine” (2006-2010) which aimed at developing a reflection on the protection of cultural heritage in the face of natural hazards. More recently, the European project CLIMA (Cultural Landscape Risk Identification Management Assessment) has taken up this issue on the analysis of soil erosion processes and archaeological remains. While these projects are mainly oriented towards monumental heritage, they have a similar basis to projects that focus on the archaeological heritage of the western Mediterranean coast.

The call for papers concerns two main themes

1 – Coastal paleo-landscapes: a heritage to reveal

Recent studies are changing the vision of coastal history from their archaeological and geomorphological points of view. This issue is an opportunity to present new research that is distinguished by their acuteness of restitution of these landscapes or by the innovative contributions to the coastal evolution knowledge, whether from geoarchaeological or archaeological points of view. In the end, the data produced constitutes a heritage that can lead to valorization through a mediation process. From the geological and geomorphological studies in progress on the littoral they can also integrate research and management’s tools of the littoral territory.

2 – Inventory and protection of coastal memory

The second objective is the sharing of the state of the art of the erosion of the coastal heritage as well as the sharing of the methods of work concerning its valuation or preservation. We propose to publish the feedback of experiences in participatory sciences and social tools on this theme. The ultimate goal is to highlight the potential of this type of initiative in the face of weak policy action.
