Experience required : 1 to 4 years

Missions

- Participation in geomorphological and geoarchaeological aspects of fieldwork in Ethiopia and Djibouti (survey, coring, sampling, section logs, documentation and help with fieldwork logistics)
- Management of geological samples in the field (inventories, export paperwork and logistics)
- Preparation and treatment of samples in the laboratory (pedo-sedimentary description and analysis of soils from archaeological and geomorphological localities and microscopic observation and description of stromatolites)
- Management of samples in the laboratory (inventories/ quotations/ orders/ shipments)
- Analyses of data (Excel, Bayesian, cartographic, GIS, modeling)
- Valorization of results (participation in international conferences, scientific publications and scientific blogs)
- Participation in CEPAM laboratory activities (team meetings and Master PPA program, General Assemblies, etc.)
- Possible co-supervision of Master 1 subject
- Possible co-organization of Master 1/2 Seminar

Activities

- Acquisition of new data during fieldwork with a focus on the study of spillway canyons and aerial coring of the Awash Delta + key locations in its watershed (~2 months).
- Study of the pedological and sedimentary dynamics of the Holocene sequences of the Abhe basin with sedimentological work on paleosols and aeolian deposits + interpretation of X-ray diffraction results.
- Description and interpretation of micromorphological thin sections (sediments/stromatolites).
- Development of innovative methods in C, O and Li isotopy on Afar stromatolites (collab. N. Vigier).
- Paleo-hydrological and geomorphological modeling (collab. L. Bruxelles, G. Duclaux).

Skills

- Field experience (section documentation/survey/coring/sampling/DGPS).
- Knowledge of arid, lacustrine and fluvial environments.
- Soil and sediment analyses in the laboratory (e.g., particle size analysis, physicochemical and magnetic susceptibility analyses, morphoscopy, SEM, XRF, and micromorphology)
- Paleoclimatic and paleoecological analyses (e.g. stromatolites, microbialites, lithology of cores)
- Basic statistical analyses (Excel, CFA, PCA)
- Basic mapping and modeling (ArcGis, QGis).
- Proficiency of Pack Office and knowledge of specialized CAD software
- Proficiency of English and French

Skills and qualities required:
- Adaptability to climatic conditions and restrictive rhythms
- Communication skills (ability to work in a large team, ability to relay relevant information, ability to present research results in public contexts, conferences, seminars, and/or scientific journals in writing)
- Ability to work in a team (collective life in the field and in research teams)
- Ability to take initiative
- Ability to respond quickly to difficult situations/deadlines (unexpected events abroad, deadlines for reports and articles)

Work Context

This job offer is part of a scientific collaboration between archaeologists, geomorphologists, geoarchaeologists and geochemists that is based on three field missions in Ethiopia (VAPOR-Afar, dir. L. Khalidi; LSA Sequence in Ethiopia, dir. C. Ménard) and Djibouti (PSPCA, dir. J. Cauliez) which aim to cross-reference data to understand the relationship between humans, environment and climate over the last 20,000 years (Later Stone Age to Neolithic societies during the Holocene) in the Horn of Africa, and particularly in the Awash River watershed and its outlet, Lake Abhe. The project is based on an archaeological, geoarchaeological, geomorphological and hydroclimatic approach and relies on field and laboratory studies in collaboration with numerous researchers, engineers and technicians.

The person will be financed by the CNRS and will be based full-time in Nice (outside of authorized missions) in the CEPAM laboratory (Cultures - Environments. Prehistory, Antiquity, Middle Ages) under the supervision of Lamya Khalidi (CEPAM) and Laurent Bruxelles (TRACES). At CEPAM, they will join a dynamic team and will work with prehistorian L. Khalidi, geoarchaeologist L. Purdue, geomatician G. Davtian, and geochronologist V. Michel, among others. The CEPAM is equipped with a microscopy platform dedicated to archaeobotany and paleoenvironments, archaeozoology, micromorphology, petroarchaeology, and use-wear analysis, as well as a SEM and a portable XRF. The candidate must be willing to live in Nice or in the surrounding area and to conduct their research full-time in the CEPAM premises in Nice.

Three fieldwork missions of 10 days to 1 month each are planned in Ethiopia and Djibouti. The candidate will likely conduct regular visits to the TRACES laboratory in Toulouse (co-supervisor L. Bruxelles) and to the LOV laboratory in Villefranche sur Mer (collab. N. Vigier), as well as to the Géoazur laboratory in Sophia Antipolis for the modelling aspects of the postdoc (collab. G. Duclaux).

This project, co-supervised by L. Khalidi (archaeologist CEPAM, Nice) and L. Bruxelles (geomorphologist TRACES, Toulouse), is financed by a project of the French National Research Agency (ANR) entitled NILAFAR (PI M. Revel, Géoazur, Nice).
