The life of labels

• Pascal BAILLY DU BOIS, oceanographer, specialist in marine dispersion and the fate of pollutants in solution in seawater or fixed on sediments

Researcher in Marine Radioecology for 30 years at the Institute of Radiation Protection and Nuclear Safety (IRSN), he was the expert responsible for marine dispersion and the future of radioactivity in the marine environment, in sea water and sediments. This activity concerned the seas of the European continental plateau and the waters of the Pacific following the Fukushima accident. A large part of his research focused on the knowledge of the currents around the CAP of the Hague and the future of radioactive releases in this area. He notably participated in the work of the North Cotentin Radioecology group intended to assess the doses received by the populations based on the in-situ measures. In 2020, appointed professor of the National Conservatory of Arts and Crafts to inaugurate the Chair of Sciences and Techniques of the Sea, he took over the management of the National Institute of Sciences and Technology of the Sea in Cherbourg in Cotentin (Intechmer), until his retirement in September 2024.

• Marianne FONT-ERTLEN, geologist, specialist in periglacial environments

Teacher-researcher in Earth Sciences at the University of Caen-Normandy, she is geologist-geomorphologist, her specialty relates to the understanding of periglacial processes and the dynamics of degradation of permafrost. Currently attached to the UMR CNRS M2C, she collaborates on research projects that analyze the impact of climate change on periglacial environments, as was Normandy during quaternary glacial periods. His work includes experimental studies in the laboratory, in particular on the processes of destabilization of frozen soil and their involvement in landslides, a relevant phenomenon in the polar and mountainous regions where permafrost is in decline under the effect of global warming.

• Lucille FURGEROT, PhD in geosciences, specializing in the study of coastal hydro-sedimentary processes in areas with strong currents.

She is a lecturer in geosciences at the University of Caen Normandy. His thesis focused on the study of hydrodynamics and sedimentary transport in connection with the maskares of the Baie du Mont-Saint-Michel. She then specialized in the study of areas with high tide open to swells. It is in this context that she became interested in the very strong currents of the Raz Blanchard off the Cap de la Hague. She studies sedimentary deposits on the seabed and their displacement with currents and waves

• David GRAINDORGE, a marine geologist specializing in marine geosciences, geodynamics and geophysics (seismic methods), and continental margins

Its autonomous approach mainly concerns the contribution of seismic data to the imaging of the structure of margins at different scales to understand its implementation, evolution, and the hazards possibly associated

• Guillaume JAMET, geologist, geoarchaeologist, specializing in Quaternary sedimentary environments associated with Paleolithic occupation sites in Northwest Europe (INRAP Grand-Ouest / UMR 8591 CNRS – LGP Thiais)

Established in Normandy, it conducts an activity of geomorphologist in preventive archaeological context and develops research in geology of the quaternary on the response of soils to environmental variations and cyclical climatic climatics of the Pleistocene. His current work focuses on Lœss formations (periglacial wind sediments) and coastal sands deposited during the last glacial (Weichseli; ~ 110,000-15,000 years). The aim of his work is to refine knowledge on regional chronostratigraphy; Fundamental for the study of ancient prehistory, but also to define "benchmarks" stratigraphic units attached to millennial climatic fluctuations (Cycles of InGaard-Oeschger) recognized in Greenland ice carrots.

• Laurent LESPEZ, geomorphologist and geoarchaeologist, specialist in Quaternary and current environments, Nature/Society interactions, and the contribution of long-term data to the management of current environments

Professor of physical geography and environment at the University of Paris-Est-Créteil and director of the Physical Geography Laboratory (LGP)-CNRS (UMR 8591), geomorphologist, geoarchaeologist and geographer, he has been studying for more than 25 years the reconstruction of long-term environmental changes and landscape dynamics. Since the start of his doctoral thesis, his work has been resolutely multidisciplinary. The emphasis on Nature/Society interactions led him to collaborate with specialists in life and earth sciences on the one hand, and human sciences (historians, archaeologists, social geographers, ...) on the other hand. Its scientific activity has always involved significant geographic mobility. Since his thesis in Greece, he has led research programs in the Aegean world, and since the early 2000s, in the northwest of France, West Africa and Arabia. His research, which relates to the reconstruction of environmental dynamics and landscapes passed since the end of the Pleistocene, has highlighted the role of anthropization in the transformation of socio-environmental systems. They have demonstrated the hybrid nature of current river systems. The emerging projects of ecological restoration of rivers and wetlands led to the solicitation of its expertise by managers of rivers and wetlands and the institutions in charge of their management. Knowledge of long -term interactions between biophysical factors and societies appears crucial to put in perspective contemporary projects of management and ecological catering. This explains the development of a new approach that integrates knowledge of long -term trajectories in current rivers management practices and the implementation of rivers restoration projects, while pursuing long -term studies.

• Cyril Marcigny, archaeologist, protohistorian, specializing in Neolithic and Bronze Age societies around the shores of the English Channel

Beyond that, of culturalist reading, he is currently developing an axis of research on the spatial analysis of archaeological data (habitats, funeral, deposits, environments) between the end of the third millennium and the beginning of the Iron Age in order to decipher the functioning of territories in a geohistoric perspective using different models and multi-agent systems. Another research axis relates to recent periods partly the vestiges of recent conflicts interviewed in the context of methodological approaches (confrontation between the memory of witnesses and archaeological interpretations, or taphonomy of vestiges, for example) or heritage (3D archaeological overall recordings threatened by erosion for VR renditions).

• Chloé MESNAGE, PhD student in physical geography, specializing in the impact of sea level rise and climate change, more generally, on coastal agriculture in Normandy.

His thesis offers a reflection on the future of Norman coastal agriculture. Its objective is to study the future of agricultural land and Norman farmers in the face of the increase (in frequency and intensity) of two main hazards: the floods by overflow of water table and the salinization of soils linked to the intrusion of the salty bevel. His research revolves around three main axes: (1) Study the evolution of hydrological and hydrogeological conditions on the Norman coastal fringe, by identifying the first observed impacts (location, dating, spatial and temporal magnitude). This axis adopts a typically physical geographical approach. (2) Quantify the share of agricultural land affected by these two hazards according to various scenarios of climate change and elevation of the sea level, in order to assess the evolution of this vulnerability. (3) Co-construct scenarios and adaptation strategies with the actors concerned (farmers, municipalities, chambers of agriculture, companies in the food industry, etc.). For this, I use an approach more turned towards social geography, in particular by conducting semi-structured interviews with these actors.

• Yohann POPRAWSKI, PhD in Geology, specializing in sedimentology and structural geology

He obtained his thesis at the University of Grenoble by studying the geometries of the diapirs and the associated synsédimentary deformation, on the Bakio site in Spain. He then continued to study the diapirs for about two years, as part of a post-doctoral contract in Barcelona. He also taught for 4 years in various universities as a contractual. Today, it develops its activities as an independent geologist in Normandy and focuses on the promotion of geological heritage, on animation and scientific mediation in geology for various audiences and actors. He is also Ambassador of the Geoparc La Hague.

• Richard RAYMOND, agronomist and geographer, specializing in understanding the factors that structure the diversity of Societies-Nature relationships

He attempts, with other people from different disciplines (ecologists, sociologists, geographers, anthropologists, etc.), to grasp the factors that structure the diversity of society-nature relations. Resolutely interdisciplinary, his work is interested in the ways in which social actors engage in the future of their territories and the ways of copeing, concretely, with environmental crises. His research tackles, more particularly, the concrete alternatives that are deployed in various situations that can be encountered in La Hague or elsewhere; These situations are documented and analyzed taking into account their contexts

• Élisabeth RIDEL-GRANGER, linguist and historian, specialist in coastal and forest toponymy and historian of techniques (shipbuilding, mills) and forest landscapes

A Doctor of Linguistics and a CNRS research engineer specializing in the analysis of historical and cultural sources at the Maison de la Recherche en Sciences Humaines (MRSH) in Caen (University of Caen Normandy and CNRS), Élisabeth Ridel-Granger long directed the MRSH's Maritime Spaces research unit, where she conducted research on the Viking heritage in Normandy, maritime toponymy, and nautical vocabulary. For the past decade, she has renewed her research focus, continuing her work on rural spaces through the study of forest landscapes, hunting activities, and mills. Resolutely multidisciplinary and working over the long term, from the Middle Ages to the present day, Élisabeth Ridel-Granger is grounded yet also has a keen eye on the sea. With Philippe Madeline, she now directs the "Environment, Society, and Rural Spaces" research unit (Rural Research Unit) at the MRSH in Caen. Her links with the territory of La Hague are long-standing, since in 1998-1999 she was responsible within the former community of communes of La Hague for the European program The maritime heritage of the Vikings in Western Europe, which led to the organization of an international symposium and the publication of its proceedings under her direction.
