Проведены исследования газового состава и изотопного отношения гелия и 4He/20Ne гидротерм в пределах Карымского вулканического центра и характера их изменений в связи с активизацией тек-тоно-магматической обстановки в этом регионе, проявившейся в конце 1995 г. и в начале 1996 г. в виде серии сильных землетрясений, извержения Карымского вулкана и мощного подводного извержения, эпицентр которого располагался в Карымском озере. Опробованы как ранее существовавшие здесь источники Карымские и Академии Наук, так и вновь образовавшиеся гидротермы и фумарола в районе подводного извержения. Совместно в этим изучен состав растворенных газов оз. Карымское

Creation of geoportals and metadata management systems as a part of spatial data infrastructure is one of the modern trends of geoinformation technologies evolution. This paper suggests one of the possible technologies for creation of peripheral node for the Academy of Sciences spatial data infrastructure based on free open source software. The author describes certain aspects of creation of a metadata catalogue as a first stage to creation of geoportal in the Institute of Volcanology and Seismology FEB RAS.

A large amount of unique scientific data has been collected in the Institute of Volcanology and Seismology FEB RAS (IVS FEB RAS) over the past years of investigations of the Kamchatka and the Kurile Island Arc volcanoes. The distributed storage of data makes it difficult to search data and to use them effectively in scientific research. Actual tasks are the integration of data into thematic information resources, organization of data access on the Internet, as well as the creation of tools for their comprehensive analysis. The paper describes VOKKIA and KVERT information web-systems developed in the IVS FEB RAS. VOKKIA is designed to integration and systematization of heterogeneous scientific data on the terrestrial volcanoes of Kamchatka, the Kurile Islands and submarine volcanoes on the surrounding seas including data on historical eruptions of active volcanoes. The KVERT system contains brief information about active volcanoes of Kamchatka and the Northern Kuriles including their hazard; provides collection and storage of operational data of visual, video, and satellite monitoring of volcanoes; automated preparation and sending KVERT releases on volcanic activity. Besides, the article describes the organization of data exchange between VOKKIA and KVERT and external information systems; describes graphical visualization services and statistical data analysis that helps to detect the relationship, patterns and trends in volcanic processes over time.

The article describes technology development, structure and content of an information system “Volcanoes of the Kurile-Kamchatka island arc” which will allow integration of wide range of volcanological data on volcanoes in Kamchatka, Kurile Islands and adjacent seas into a single information environment available for Internet users.

Development of spatial data infrastructure (SDI) is one of the modern trends of geoinformation technologies. SDI of the Institute of Volcanology and Seismology (IVS) FEB RAS has been developing since 2008. Metadata management system, storage and management of spatial data system and geoportal are the main elements of the SDI. Metadata management system provides powerful tools for creation, editing, browsing of metadata, efficient instruments for searching for data and services. The geoportal is a single point of access to metadata catalogue, collections of volcanological and seismological data, and geoservices. One of the collections is available in the Volcanoes of Kurile-Kamchatka Island Arc (VOKKIA) information web system, which integrates available volcanological data related to the volcanoes in Kamchatka, the Kurile Islands and adjacent seas. Today the VOKKIA system includes the sections: Volcanoes, Eruptions, Rocks, Monitoring, Images, Geoservices, Bibliography. Kamchatka Holocene Volcanism geoservice of the VOKKIA system shows the centers of both historic and prehistoric volcanic eruptions, age and composition of deposits etc. This paper gives a detailed description of development and core capabilities of the geoservice. Based on the international OGC standards, the geoservices allow the wider range of users to access the spatial data in contrast with the desktop GIS. Spatial metadata, data and geoservices published on the IVS FEB RAS Geoportal can be easily found through the Internet and are available for the international scientific society contributing into increased rate of data exchange between researchers.
