The International Scientific Studies project invites scientists to participate in an evaluation of the Comprehensive Nuclear-Test-Ban Treaty’s verification regime.
The International Scientific Studies project (ISS) will evaluate the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) through a series of scientific studies and assessments, which will address the readiness and capability of the CTBT to detect nuclear explosions worldwide.
Promoting global participation
The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) is the facilitator and coordinator of the project but will not be performing the evaluation. This will be the task of the international scientists and institutions participating in the project. Some sponsors have made funding available through voluntary contributions, which could be used to promote global participation in this project, especially experts and institutions from developing countries.
Performance of the verification regime
The studies and assessments will highlight progress made in seismology, hydroacoustics, infrasound and radionuclide monitoring over the last ten years. These are the four technologies used by the 337 facilities comprising the CTBT’s International Monitoring System (IMS) to monitor the Earth for evidence of nuclear explosions. The performance of the CTBT’s global verification system and its ability to detect and locate observed events will be examined. In the CTBT context, an “event” is any physical occurrence that is registered by the IMS, be it a natural or a man made event, an earthquake or an explosion, a chemical or a nuclear explosion. An evaluation will also be made of the timeliness, quality and quantity of data which are produced, transmitted, processed and distributed to Member States by the International Data Centre (IDC) in Vienna, Austria.
