ISS Topics and Coordinators

ISS Topics and Coordinators

1.  SYSTEM PERFORMANCE
      The International Monitoring System (IMS) is a complex global system comprising 337 monitoring facilities. The   timeliness, quality and quantity of data which are produced, transmitted processed and distributed are essential elements to be evaluated.

Coordinators:
Prof Nicholas Kyriakopoulos
George Washington University, US

Dr Thierry Heritier
French Atomic Energy Commission


2.  SEISMOLOGY

      The work will concentrate on understanding and increasing the capabilities of the detection and location of seismic events globally and on exploring how to use seismic information to more fully characterize events.

Coordinators:
Prof Zhongliang Wu
China Earthquake Administration

Prof Barbara Romanowicz
University of Berkeley, US

3.  HYDROACOUSTICS      
      The hydroacoustic network comprises stations which detect both T and H phase signals. . Detection and location capabilities of this network will be evaluated, as will the coverage. Information on the events detected by the network will be compiled. Synergies with seismic observations will be explored.

Coordinators:
Dr Wolfgang Jans
Federal Armed Forces Research Institute for
Underwater Acoustics and Marine Geophysics, Germany

Prof Kiyoshi Suyehiro
Japan Agency for Marine-Earth Science and Technology


4.  INFRASOUND
      The infrasound network is unique and the full range of its capabilities is yet to be established. The studies have three main objectives: firstly, to make estimates of the detection and location capabilities of the network at regional and global distances; secondly, to explore ways to improve these capabilities; and thirdly, to enhance the understanding of observed events and propagation of acoustic waves through the atmosphere.

Coordinators:
Dr Elisabeth Blanc
French Atomic Energy Commission

Dr Lars Ceranna
Federal Institute for Geosciences and Natural Resources, Germany

5.  RADIONUCLIDE OBSERVATIONS
    
Both the particulate and the noble gas monitoring networks are unique on a global scale and their performance will be assessed thoroughly. This includes a compilation of information on frequently occurring anthropogenic radionuclides and on the natural background.

Coordinators:
Prof Wolfgang Weiss
Bundesamt fuer Strahlenschutz, Germany

Dr Harry Miley
Pacific Northwest National Laboratory, US


6.  ATMOSPHERIC TRANSPORT MODELLING
    
Modelling and tracking the movement of air volumes is crucial for estimating the locations of sources of radionuclide particulates and noble gas observations. The aim of the studies is: to estimate the capabilities of present models and procedures and to explore ways to further improve their accuracy.

Coordinators:
Dr Richard Hogue

7.  ON-SITE INSPECTIONS
     
When conducting an on-site inspection (OSI), a number of geophysical techniques can be used. These techniques include passive, resonance and active seismic measurements as well as gravity, electric and magnetic field mappings. Further, noble gas such as Xenon and Argon will be measured on-site. Argon-37 measurement is a unique technology. Data collected from various methods have to be fused and interpreted for decision making purposes. An important task is to explore how recent scientific and technical advances in these technologies can be applied to an OSI.

8.  DATA MINING AND DATA EXPLOITATION
    
The development of modern IT-based analysis methods, data mining, has been outstanding over the last decade. An important cross-cutting undertaking is to explore if and how such methods might be applied to the analysis of data in all stages of station and network processing as well as in event categorization and screening.
