Spectrum 22: August 2014

In the 22nd issue of Spectrum, Prime Minister Abdullah Ensour of Jordan describes his country’s longstanding support for the Comprehensive Nuclear-Test-Ban Treaty (CTBT). In particular, he explains the significance of Jordan’s decision to host the Integrated Field Exercise 2014 (IFE14) at the end of the year and its importance for peace and stability in the Middle East. This huge logistical undertaking will be the largest, most realistic and challenging on-site inspection simulation ever conducted by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO). It will involve a thorough search of a clearly defined inspection area to determine whether or not a nuclear explosion has been conducted.


On 11 April 2014, the Group of Eminent Persons (GEM) released a joint statement outlining a number of strategic approaches and modes of action designed to promote the CTBT’s entry into force. This group of global leaders and internationally recognized experts in the field of nuclear non-proliferation and disarmament was established at the United Nations headquarters in New York on 26 September 2013 at the initiative of CTBTO Executive Secretary Lassina Zerbo.  The GEM statement was issued at the end of a two-day meeting in Stockholm, Sweden, which was hosted by Swedish Foreign Minister Carl Bildt.


Northern Utah Director with the U.S. Senate, Ryan Wilcox, opposed his country’s ratification of the CTBT in 1999. However, he argues that there is now a strong case to justify ratification. He concludes that such a move will ensure “that we can both preserve our nuclear deterrent, and prevent further proliferation both at home and by enemies abroad.”  As one of the eight remaining States that must still ratify the CTBT before it can enter into force, U.S. ratification would be a highly significant move.


Also in this issue, U.S. author and journalist William Lambers provides an analysis on the prospects of ratification of the Treaty by the United States, while Pakistani journalist Rizwan Asghar explores the option of the CTBT’s provisional application and lists some of the many benefits that Pakistan would reap by joining the Treaty.


CTBTO staff members Georgios Haralabus, Lucie Pautet, Jerry Stanley and Mario Zampolli, provide readers with a unique insight into the technical and logistical challenges encountered during the reconstruction of the CTBTO’s hydroacoustic station HA03.  Located on Robinson Crusoe Island in Chile’s Juan Fernandez Archipelago, this remote station is fully operational again after its destruction by a tsunami in 2010.


In addition to listening for underwater sounds generated by nuclear explosions, scientist Mark Prior explains how hydroacoustic technology can increase the understanding of different “soundscapes’ in the underwater world. These ‘soundscapes’ include noises produced by whales, breaking ice, earthquakes and volcanoes.


As the starting date of the organization’s largest ever integrated field exercise approaches, CTBTO staff members Gordon MacLeod and Matjaz Prah compare the elements and techniques for the upcoming exercise in Jordan with those employed in the last full-scale on-site inspection simulation, IFE08, which took place in Semipalatinsk, Kazakhstan, in 2008.


Finally, the paintings by Doug Waterfield from the University of Nebraska at Kearney, USA, on the cover and inside Spectrum 22 illustrate the power of art in educating and communicating political messages. The paintings are part of the artist’s ‘Doomtown’ series, which were on display at the Vienna International Centre in an exhibition to mark the International Day against Nuclear Tests on 29 August.

Spectrum 21: September 2013

This 21st issue of Spectrum features an address by the President of Burkina Faso, Blaise Compaoré, who became the first head of state to address the CTBTO Preparatory Commission at its 40th Session on 13 June 2013. Compaoré shares his vision for peace and international security in a world without nuclear weapons, calling on those remaining States that have not yet signed or ratified the CTBT to do so in order that the Treaty can become legally binding. He also describes the usefulness of CTBTO monitoring data which “are of great importance in defining effective responses to natural risks and disasters.”


As Co-Presidents of the Conference on Facilitating the Entry into Force of the CTBT at the UN Headquarters in New York on 27 September, Hungary’s Minister for Foreign Affairs, János Martonyi, and Indonesia’s Minister for Foreign Affairs, Marty M. Natalegawa, explain why the CTBT’s entry into force is of paramount importance. Outlining their priorities in promoting this objective, Martonyi calls on the remaining Annex 2 States, especially the United States, to ratify. Appealing to the United States as a NATO partner, he states that “ratification by the United States is in no way detrimental to NATO’s nuclear deterrent, but that it would, on the contrary, enhance global security.” Expressing his concern over the nuclear tests announced by North Korea in 2006, 2009 and 2013 which have exacerbated tensions in the region, Natalegawa says: “Such nuclear tests highlight the urgent need for the CTBT’s entry into force “


Iceland’s Minister for Foreign Affairs, Gunnar Bragi Sveinsson, maintains: ‘It is abundantly clear that all non-proliferation efforts are critical in tackling the threat of terrorists acquiring nuclear weapons. A fully ratified and implemented CTBT is an indispensable building block for these efforts.” He also highlights the potential use of CTBT monitoring data in helping to mitigate the effects of natural or man-made disasters, particularly in terms of monitoring volcanic eruptions, which he explains is of great interest to Iceland.  


This issue also features excerpts of keynote addresses made at the CTBT: Science and Technology 2013 Conference in Vienna, Austria, in June 2013. These include: former head of the International Atomic Energy Agency, Hans Blix; former U.S. Under Secretary of State for Arms Control and International Security Affairs, Ellen Tauscher; former Director of the Los Alamos National Laboratory, Siegfried Hecker; and Director for Strategic Affairs in the French Ministry of Defence, Michel Miraillet. The keynote speakers present a range of arguments as to why countries that have not yet ratified the CTBT should delay no longer.


Miaki Ishii from Harvard University describes how the CTBTO’s seismic stations “serve unexpectedly well as powerful telescopes to view inside the Earth.”  Detailed knowledge of the internal structure of the Earth is essential, she explains, for unravelling its dynamics and history.


An article on ‘Joining forces to reduce radioxenon emissions’ highlights some of the recent collaboration between the CTBTO and radioisotope producers such as the Belgian-based Institute for Radioelements to achieve this goal.  


With preparations for the next Integrated Field Exercise in Jordan in 2014 well underway, Spectrum 21 features a photo story depicting ‘Build-Up Exercise III’ which took place in Hungary from 26 May to 7 June 2013. This exercise will simulate an on-site inspection almost in its entirety. Also on this theme, an article by the CTBTO’s Aled Rowlands describes the role of airborne imagery in an on-site inspection.

 

 

Issue 20: July 2013

In this 20th issue, the Foreign Minister of Iraq, Hoshyar Zebari, reports on the steps taken by the Iraqi parliament towards ratification of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and the importance Iraq attaches to promoting the Treaty’s entry into force. Ambassador Thomas Pickering, who helped the Kennedy administration draft the Partial Test Ban Treaty, describes why the case for ratification of the CTBT by the United States is stronger than ever. Zia Mian from Princeton University focuses on the role of civil society in South Asia in advocating nuclear disarmament.


Columbia University’s Paul Richards explains the seismic findings of the nuclear test announced by North Korea on 12 February; we also elaborate on the radionuclide findings almost two months later. Astronomer Margaret Campbell-Brown from the University of Western Ontario explains how CTBTO data have helped us understand the characteristics of the meteor over the Ural mountains on 15 February. Anders Ringbom and Anders Axelsson of the Swedish Defense Research Agency describe the key role played by noble gas detection systems in responding to the Fukushima nuclear accident in March 2011 and some of the lessons learned.


This issue also features an interview with CTBTO Executive Secretary Tibor Tóth in which he discusses a range of issues related to nuclear non-proliferation, including the main challenges and achievements during his eight years as head of the organization.


Finally, the paintings by Elin O’Hara Slavick from the University of North Carolina at Chapel Hill on the cover and inside Spectrum 20 illustrate the power of art in educating and communicating political messages.

 

 

Issue 19: September 2012

In this 19th issue, the Foreign Ministers of Chile and Finland, Alfredo Moreno and Erkki Toumioja, make a strong political pitch for the Treaty and also highlight the contribution of CTBT verification data for disaster mitigation. They are joined by two prominent South Asian thinkers: former UN Under-Secretary-General for Disarmament Affairs Jayantha Dhanapala, and Hindustan Times Foreign Editor Pramit Pal Chaudhuri.


Nuclear physicist Siegfried Hecker explains why nuclear armed States stand to gain more than they lose from CTBT ratification and Tatsujiro Suzuki, Vice Chairman of the Japan Atomic Energy Commission, provides an invaluable insight into the Fukushima accident. Elena Sokova from the Vienna Center for Disarmament and Non-Proliferation explains why nuclear disarmament and non-proliferation education should be sustainable and global, with the CTBTO’s Capacity Development Initiative a welcome development in this field.


Ik Bum Kang from the Korea Institute of GeoScience and Mineral Resources outlines some of the challenges of operating and maintaining primary seismic station PS31, one of the CTBTO’s closest station to the North Korean nuclear test site. Former CTBTO staff member Kirsten Haupt describes how practice makes future on-site inspection inspectors perfect, and guest writer Angela Leuker how the perception of nuclear war has changed over recent decades.

 

 

Issue 18: March 2012

In this special 15th anniversary issue of Spectrum and video, a number of former and current staff share some of their personal memories of the journey since March 1997 when the CTBTO began its operations in Vienna. In the words of the first Executive Secretary of the CTBTO, Wolfgang Hoffmann: “We were a very small group of people with a huge task.”


Although confronted with numerous challenges, many staff refer to the enthusiasm, optimism and team spirit which have made it all worthwhile and have enabled great progress to be made.  Reflecting on the last 15 years, the CTBTO’s Executive Secretary Tibor Tóth concludes: “I think we can be proud that we have managed to deliver on things that were just dreams in March 1997 and to turn them into reality by spring 2012.”

 

 

Issue 17: September 2011

In this 17th issue of Spectrum, the former leader of the Soviet Union, Mikhail Gorbachev, calls for a total ban on nuclear testing. In his article entitled The Comprehensive Nuclear-Test-Ban Treaty: Helping to create a truly global community, Gorbachev states that we should not be content with the current virtual moratorium on nuclear testing “because commitments that are not legally binding can easily be violated.”  He urges the nine ‘rejectionist’ countries that must still ratify the CTBT to do so in order for the Treaty to enter into force.


The Prime Minister of Trinidad and Tobago, Kamla Persad-Bissessar, states that “the CTBT stands as a beacon, lighting the path towards a peaceful world, free from nuclear explosions, whether for military or for peaceful purposes. For this reason, Trinidad and Tobago signed the CTBT on 8 October 2009 and ratified it on 26 May 2010.” She also describes how CTBT monitoring data can be used for disaster mitigation, especially by providing faster tsunami warnings, and outlines efforts to establish a tsunami warning system in the Caribbean. And recognizing the vital links between women and disarmament, the article stresses Trinidad and Tobago’s belief that “all discussions on disarmament, conflict resolution and peace-building must include women to ensure an expansion of their role."

 

 

Issue 16: May 2011

In this 16th issue of Spectrum, Princess Sumaya bint El Hassan of Jordan underlines the importance of focusing on the nexus between nuclear safety and nuclear security. In her article entitled Safeguarding the Arab Renaissance, Princess Sumaya explains that: “We in Jordan are ready to help shape our nuclear renaissance safely and securely, with a full commitment to non-proliferation and disarmament in our region.” She also outlines a proposal to establish sub-National Data Centres at several science universities in Jordan “to increase the use of invaluable IMS [International Monitoring System] data to aid scientific research in fields as diverse as seismology, geology, the environment and ICT,” and her desire for the establishment of a Regional Data Centre in her country to help expand Treaty acceptance in the region.


Three analysts from the International Data Centre (IDC), geophysicist Marcela Villarroel, seismologist Jane Gore, and physicist Carla Pires, provide unique insights into one of the CTBTO’s core activities – analyzing the data transmitted by the IMS to the CTBTO headquarters in Vienna. They talk about some of the challenges and rewards of their work and the importance of ensuring that CTBTO Member States receive data bulletins and analysis reports in a timely manner.

 

 

Issue 15: November 2010

The articles in this issue of Spectrum are from a diverse range of voices, setting a new precedent for the publication. Former U.S. Republican Senator Jake Garn of Utah urges the United States to provide the leadership needed to stop the proliferation of nuclear weapons by permanently ending nuclear weapons testing and ratifying the CTBT. Talat Masood, former Secretary for Defence Production in the Ministry of Defence, Pakistan, outlines the near term and long term developments that will influence the nuclear landscape. Bharath Gopalaswamy, formerly of the Indian Space Research Organization and now at the Stockholm International Peace Research Institute (SIPRI), highlights the benefits of CTBTO membership and points out that States that have not signed the Treaty are at a disadvantage since they do not have access to verification data. Xia Liping from Tongji University in China explains why CTBT ratification is in China’s strategic interests. And Michel Nambobona, the Director General of the National Data Centre in the Central African Republic, outlines his personal role in helping to secure CTBT ratification by his nation.


Spectrum 15
also covers various verification-related issues. On-site inspection expert, Charles Carrigan, describes the evaluation of equipment during the CTBTO’s 2009 Noble Gas Field Operations Test (NG09) in Slovakia. And finally, our own infrasound experts describe some of the recent experiences gained by the infrasound network.

 

 

Issue 14: April 2010

In this 14th issue of Spectrum, several world leaders reinforce the importance of the CTBT entry into force. President Jurelang Zedkaia of the Marshall Islands describes the legacy of nuclear weapon testing on his country and urges full global acceptance and ratification of the Treaty. Kanat Saudabayev, the Foreign Minister of Kazakhstan, summarizes the 13 years of cooperation between Kazakhstan and the CTBTO and his country’s strong support for the CTBT. The Foreign Minister of Australia, Stephen Smith, and the Foreign Minister of Mexico, Patricia Espinosa Cantellano, both reiterate the unwavering commitment of their respective countries to a CTBT in force and outline the different ways in which Australia and Mexico have supported the Treaty and the CTBTO over the years. Ambassador Stephen Ledogar, the U.S. chief negotiator of the CTBT, expands on a number of key issues from the Treaty’s negotiations, which continue to be relevant for today’s debate.


Spectrum 14 also covers a range of verification-related issues and some of the Treaty’s potential scientific applications. On-site inspection expert, John Walker, highlights the main lessons of the Integrated Field Exercise 2008, the largest ever on-site inspection exercise carried out by the CTBTO in Kazakhstan in September 2008. Data mining experts, Stuart Russell, Sheila Vaidya and Ronan Le Bras, describe different machine learning concepts. Flore Samaran, a specialist in bioacoustics and whale conservation, writes about the use of hydroacoustic data for monitoring large whales.
