During the last year the activities of Romanian scientists interested in glacial and periglacial geomorphology continued in all branches of the Romanian Carpathians.
The project ‘The impact of the climatic changes upon the Holocene and present dynamics of the alpine environment from the Romanian Carpathians. Implications in the risk management and landscape’s arrangement’ (MEDALP) financed by CNCSIS (National Council for Superior Education Scientific Research) and led by P. Urdea (West University of Timisoara) and A. Vespremeanu-Stroie (University of Bucharest), continued with new investigation in the Retezat, Fagaras and Sureanu mountains. The acquisition of a complex geophysical system PASI 16GS24 by West University of Timisoara opens new possibilities for investigations of some landforms and deposits of alpine areas in the Southern Carpathians. Application of 2D electrical resistivity tomography (ERT) began with measurements in the Fagaras, Retezat and Sureanu mountains on different geomorphic landforms such as rock glaciers, scree slopes, solifluction lobes, fossil patterned grounds and a glacial overdeepening depression filled with postglacial sediments. ERT results of the Ana and Pietrele rock glaciers of Retezat Mountains indicated typical structures, and the presence of ice-rich bodies. The presence of permafrost in the area was also indicated by BTS measurements, and by the low temperatures (< 2ºC) of the springs situated at the base of the front of rock glaciers. Core samples were extracted from cores of glacial lakes and also tree rings for the reconstruction of the postglacial landscape.
In the summer 2007 ice caves, a particularly form of sporadic permafrost and/or extra-zonal permafrost, was the focus of a team from the Department of Geology and Speological Institute E. Racovitza Cluj – Napoca. Led by B. Onac, the structure and thickness of ice of Glacier Scarisoara- (Apuseni Mountains) was explored with ground penetrating radar. S. Simoni (University of Pitesti) successfully finished his PhD dissertation The Geomorphological Study of the Doamnei River Basin in May 2007, with a part dedicated to glacial and periglacial landforms. The teams of West University of Timisoara, University of Bucharest and University of Suceava continued the research on developing the chronology of the glaciation of the Romanian Carpathians, and to identify the palaeoenvironmental and palaeoaltitudinal zoning of the periglacial belt, permafrost and frozen ground conditions.
