The Ploemeur-Guidel observatory (Britanny, France) is focusing on surface-depth relationships in a fractured crystalline geological context and oceanic climate. It is built on 2 sub-sites, one highly anthropized, the other in natural state. In Ploemeur, groundwater has been pumped since 1991, supplying more than 1 million m3 of clean drinking water annual at a sustainable rate. Such high productivity is explained the specific fractured network in granite and micaschists, draining deep geological layers (~400 m). Extracted water quality is very good, with limited nitrate concentration, in a region that has been strongly affected by widespread pollution. Guidel site is in a similar, but natural context. Deep iron-rich groundwater is upflowing, creating surface and deep groundwater-dependent ecosystems, and feeding a classified coastal wetland. Both sites have a very dense equipment to study rapid to long-term surface-depth exchanges: a flux tower, unsaturated zone monitoring, a network of ~50 shallow (<10m) and deep boreholes (>80m), hydrochemical, temperature and deformation. An well-characterized fractured experimental site offers the possibility to conduct experiments to test innovative instruments and develop new methodologies

Groundwater comprises approximately 30 percent of the Earth’s total freshwater, serving as a vital resource for both humans and ecosystems. As an essential source of drinking water for humans and sustenance for vegetation, groundwater plays a key role in the terrestrial water cycle. It acts as a buffer, enabling adaptation to climate variability and extreme events like floods and droughts. Therefore, understanding groundwater storage is important for both ecological and15 societal reasons.

Title: InterActic : A millennium of interaction between societies and environments in Arctic and sub-Arctic regions (Canada and Greenland) Abstract The InterArctic project focuses on vulnerability, resilience and adaptation of northern societies facing global change. The rapid current warming of Arctic and Subarctic climates has already produced many changes in the social, economic and cultural behavior of the populations inhabiting these regions and more changes are expected to come. Few of the changes are considered to be positive or not disturbing the fragile balance between human and the environment. Populations of these areas have to face these challenges, and in this context, looking at the past provides the opportunity to document the complex relationships between climate, ecology and human societies, which may provide deeper understanding into ways of better facing the future. The chronological frame of the project encompasses the last millennium, a well-documented period by both ice core data and historical archives. The study area includes Eastern Canada (Nunavik, Nunavut and Nunatsiavut) and Greenland (South and North). Around 1000 years cal. AD, some of these areas witnessed the meeting between European farmers coming from Scandinavia, and hunters-fishers arriving from Beringia. Today, these two lifestyles are still coexisting, with farming in South Greenland, and hunters/gatherers/fishers in Nunavik, Nunavut, Labrador coast and Greenland. Within these study areas, our aim is to document 1000 years of interactions between Thule/Inuit people, Norse settlers and their environment, through an interdisciplinary approach exploiting different kinds of natural archives. The use of pedo-sedimentary archives (lakes, peat deposits, cryosols, anthrosols) and palaeoenvironmental multiproxy analyses will highlight landscape evolution, climatic and anthropogenic forcings upon ecological processes. Archaeological sites, and more specifically archaeological soils, ecofacts and artefacts, will give precious information about the nature of these interactions. The complementary anthropological/cultural approach will focus on human memory, perception, practices and prospects of environmental and social changes, archaeological heritage and past settlement location choices, of six communities in Greenland and Canada. These issues will be explored in an interdisciplinary work through open interviews and co-design workshops bringing Inuit elders and youth together with project researchers. Coproduced knowledge (blending traditional and scientific), including Inuit visual documentation of the community changes and the writing of science fiction narratives, as well as cognitive maps (Inuit internal representation), will then be shared through innovative educational projects such as an interactive web platform designed to share project results, involving local partners in Greenland and Canada as well as French secondary schools and universities.

"Relevés de carabes aux interfaces entre parcelles cultivées et leurs bordures (sud Ille et Vilaine) - ZAAr" Objectif : étudier les flux et l'activité-densité associée des carabes entre cultures de différente nature (céréales d'hiver et maïs) et avec leurs bordures (haies), réparties dans 15 interfaces de cultures au sud de l'Ille et Vilaine. Protocole : échantillonnage des espèces et de leurs abondances (ou activités-densités) dans les parcelles et leurs bordures par piégeage, avec 2 stations de piégeage par parcelle et 2 stations de piégeage par bordure de champs (2 pots par station) ; échantillonnage des flux de carabes aux interfaces entre parcelles et entre parcelles et leurs bordures avec des pièges à interception (4 pots par piège à interception) ; pièges ouverts en continu et relevés toutes les 2 semaines pendant 8 semaines au printemps et pendant 4 semaines à l'automne.
