WG5 - Magnetic and Other Geoscience Data and Infrastructures

1. Pavel Hejda, IG ASCR, Prague Antonio Meloni, INGV, Rome WG5 - Magnetic and Other Geoscience Data and Infrastructures Up to now, 31 RI Questionnaires were submitted into the EPOS Collaborative areas. The collection is rather inhomo-geneous, which results already from the scope of the WG. The RIs can be sorted out (with some simplifications) into 5 clusters. Some infrastructures would better fit to another Working Group. It is indicated in the last column of the table. RESEARCH VESSELS AND MARINE RESEARCH Three multipurpose research vessels operated by Geological Survey of Ireland enables offshore and deep sea survey. R/V Mare Nigrum (see figure) and ROV GEOS, operated by GeoEcoMar, Romania are dedicated to multipurpose surveillance and marine research covering the entire Black Sea. The project was supported by 2 M€ from the EC. EUXINUS is a joint Romanian-Bulgarian marine observation and early-warning system and was also supported by EC Structural Funds. The Hellenic Navy Hydrographic Service operates an network of tide gauges. The National Centre of Marine Research operates a network of deployed oceanographic boys. The networks are part of European Sea Level Service and the data are also distributed via web http://www.ioc-sealevelmonitoring.org/index.php operated by Intergovernmental Oceanographic Commission (IOC) of UNESCO. . GEOMAGNETIC OBSERVATORIES The RI Questionaires involve 19 of 30 European INTERMAGNET observatories. Some of them are part of multidisciplinary facilities. In spite of this, the geomagnetic community is not yet sure about the degree of integration of data into EPOS infrastructure. The geomagnetic data are already well integrated in the INTERMAGNET and WDCs, which are world-wide structures. The conclusion from the last discussions was to to follow the development of the project and keep the decision on the form of participation open. GROUND WATER AND CO2 MONITORING Grounwater monitoring and chemistry carried out by Geological Survey of Sweden and Laboratório Nacional de Energia e Geologia, Portugal, are carried out in the frame of environmental protection. Monitoring of CO2 and groundwater in West Bohemia is amed at better understanding of the changes in the regime of discharge and seismogenic influences in the region of seismic swarms. CONCLUDING REMARKS The treatment of multidisciplinary facilities requires communication with other working groups. In some cases the multidisciplinary facilities could be split into more homogeneous parts. The question how the geomagnetic data will be included into (or affiliate with) EPOS is still open. This issue will be discussed again during the IAGA Observatory Workshop in June 2012. Some infrastructures would better fit to other working groups. The WG5 team needs to be recruited in order to better cover the broad spectrum of infrastructures. DATABASES AND GIS LNEG/Portugal submitted questionaire on GEOSEAS, which is Pan-European infrastructure for management of marine and ocean geological and geophysical data coordinated by BGS. Possible cooperation with EPOS should be discussed with BGS. GIS and data basis infrastructure was also submitted by Romania. MULTIDISCIPLINARY FACILITIES Some infrastructures cannot be easy separated into single-disciplinary parts from finacial, organizational or legal reasons. Co-operation with other working groups is required. INTERMAGNET The INTERMAGNET is a global network of co-operating digital magnetic observatories adopting modern standard specifications for measuring and recording equipment in order to facilitate data exchange and the production of geomagnetic data products in close to real time (often within one hour, 3 days delay at the latest). Data are sent to data collection centres called Geomagnetic Information Nodes (GIN). Recently there are about 120 INTERMAGNET observatories worldwide, and six GINs, two located in Europe. GINs also act as data supply centres, with data delivery by electronic mail or by direct download from web pages hosted at GINs (http://www.intermagnet.org). Definitive data are collected annually for inclusion on a INTERMAGNET DVD and are also available from the web. CONDITIONS OF USE FOR DATA PROVIDED THROUGH INTERMAGNET The data made available through INTERMAGNET are provided for your use and are not for commercial use or sale or distribution to third parties without the written permission of the institute operating the observatory. Publications making use of the data should include an acknowledgment statement. A citation reference should be sent to the secretary@intermagnet.org for inclusion in a publications list on the INTERMAGNET website. ABOUT MAGNETIC OBSERVATORIES Magnetic observatories play a dual role: (1) production of variation data with at least one-minute sampling for the study of geomagnetic activity (2) production, at stable sites, of long-term, continuous records of data of quality suitable for studies of the secular variations of the main (core) geomagnetic field; high quality is achieved by making regular absolute measurements to determine baselines for the continuous recordings. The geomagnetic observatories usually also carry out repeated measurement on denser network of so-called repeat stations, These data could of interest for EPOS.
