Hydrological and glaciological data were gathered in the watershed (1.37 km2) of the Antizana Glacier 15 (0.7 km2) in the periods 1997–2002 and 1995–2005, respectively. In addition, tracer experiments were carried out to analyse the flow through permeable morainic deposits located between the glacier snout and the runoff gauging station. Over 11 years, the mean specific net balance of the glacier was negative (–627 mm w.e.), despite the occurrence of positive values in the La Niña years (1999–2000). From the glacier net mass balance between 1997 and 2002, it was found that the mean flow originating from ice melt was significantly higher than the mean discharge measured at the hydrological station. Analyses of tracer experiments and of the different components of the hydrological balance suggest groundwater flow that originates below the glacier accounts for the remaining water. This result is important for regional analyses of available water resources and for the relationship between hydro-cryospheric processes and volcanic activity.

Course Titled: Environmental Problems and Sustainability. http://scipeople.com/publication/70030/; Lecturer: Serguei Ostroumov (Dr. Sergei A. Ostroumov) Institution: Moscow State University Country: Russia Site: http://web.ceu.hu/crc/Syllabi/alumni/envsci/ostroumov.html The course is intended to show the problems of the modern environment and importance of the fundamental concept of sustainable development. It is important to make a point in stressing the role of science in finding the solutions. The course is intended for the university students mainly of the 2nd and 3rd years of education but can be adapted for students of other years as well. The course can be included in the program of education of the students majoring in both science and humanities. The lecture course can be supplemented by the assignment of writing a course work on any relevant topic mentioned in the course. The course work can be focused on a scientific aspect of environmental change or on environmental law or on implementing environmental law and agreements. The course is structured into 9 blocks that are labeled below as 'parts'. Because the parts are of unequal size, they do not coincide with the division into lectures.

According to one of the approaches to the definition of criteria for the phenomenon of life, the key attribute is the ability of the system for some self-regulating and self-supporting. Part of such holistic functions of aquatic ecosystems as self-regulating and self-supporting is their cleaning the water via a multitude of various mechanisms. This paper presented some fundamental elements of the theory of ecosystem self-purification which emphasizes the importance of the four functional biological filters that are instrumental in purification and upgrading the quality of water in aquatic ecosystems. http://www.ncbi.nlm.nih.gov/pubmed/9857844?dopt=Abstract; PMID: 9857844 [PubMed - indexed for MEDLINE]; http://scipeople.com/publication/69542/; ------------------------------------------------------------------------------------------------------------------ 5.
