Abdel-Aziz Abdrahamane Yassine  

Graduated MSc Student

Abdel-Aziz Abdrahamane Yassine holds a BSc degree in Geology from the Adam Barka University of Abéché. After his graduation in 2015, he started his first internship at the Ministry of Mines, Oil and Energy of Chad and second internship at the laboratory of water and environmental analyzes (LABEEN). In 2016 he was accepted at the University of N'Djamena for a MSc degree in Hydrogeology and Geographic Information System (Hydro-GIS), in 2018 he obtained his MSc degree, entitled: The geological and hydrogeological structure of the aquifer in the city of N'Djamena: implication for 3D architecture. He has participated in some international conferences, such as the international scientific conference on Lake Chad ecosystems organized as part of the GELT project, and in conference on cartography of water resources sponsored by the CNRD (National Center for Research and Development). As part of a large-scale wastewater management program of the city of N'Djamena, he has contributed with his knowledge in hydrology as part of drilling 120 boreholes in the region of Chari Baguirmi. In 2019 he started an assistant position in practical fieldwork at the University of N'Djamena. Abdel-Aziz enjoys open air sport, especially football as well as travel. 

Abdel-Aziz is currently a PhD student at the Bar ilan University (Israel).

Paleo-environmental reconstruction of the northern Levantine corridor for the time period since the LGM: insights from Lake Hula

Lake sediments are fantastic archives of geological processes as well as of environmental and climate change occurring on land. The sediments from Lake Hula (northern Israel), may hold valuable information on the variability of the environmental setting through time. Previous studies carried out on ~30 boreholes (as part of a lignite and gas exploration project in the 1970s) supply the geological information on the uppermost 200 m sequence of the Hula Basin. For the purposes of the current study, we aim to carry out a comprehensive sedimentological study of the uppermost 20 m, aiming to provide information on the environmental conditions ruling the region since the LGM. As part of the current project, we aim to check for grain size variability, coupled by geochemical analyses (XRF) and mineralogy (XRD, SEM).

(b)Principal component analysis 1 (PCA1) score for the L07 core. (c) Content of end member EM1, EM2 and EM3 in core L07.(d) Magnetic susceptibility (MS) variations (in SI) from core L07.(e) Lake Level fluctuations from the Dead Sea basin (Waldmann et al., 2010). (f) Oxygen Isotope record from Soreq Cave (Langgut et al., 2021). (g) Simplified pollen from core L07 (Weinstein-Evron, 1987). (h) Oxygen Isotope record from the East Mediterranean (Kroon et al., 1998). (i) Summer Insolation at 30° N and orbital eccentricity (dashed curve) (Berger & Loutre, 1991).
