GIS Global Mapping Tool for ISOHIS

The scientific and practical values of the isotope signatures of various components of the water cycle have been recognized in various international fora and scientific programmes. The addition of GNIR (Global Network of Isotopes in Rivers) and MIBA (Moisture Isotopes in the Atmosphere and Biosphere) data to the Global Network of Isotopes in Precipitation (GNIP) has further strengthened the Agency's monitoring activities to ensure a broader and extensive use of isotope tools to understand functioning of and interactions between the water cycle and other biogeochemical cycles. A substantial increase in the request for isotope data for hydrological, climatic and ecological applications has been observed during the last years. To cater to the need of researchers and practitioners, the Agency has undertaken a number of initiatives to further improve the overall quality and spatial coverage of isotope data.

A preliminary version of an integrated, computer-assisted mapping environment for the dissemination of chemical and isotope hydrological data has been further improved in collaboration with the University of Vienna. Existing data from the Agency's databases related to water resources- all included under the Isotope Hydrology Information System (ISOHIS) - will be used in a Geographical Information System (GIS) application. A full fledged online information application which is under testing, would be available online worldwide via Internet browser facilitating free access while eliminating limitations like place, time, technical issues or software installation.
