The 5th International Dialogue on Underwater Munitions (IDUM) was held at St. Mary’s University in Halifax, 28 -29 May 2014. Underwater Technology Demonstrations were scheduled by Private Sector companies (unmanned vehicles). Oil and gas exploration and development, regulatory committees, environmental, technology and science companies and organizations attended with delegates from more than 20 countries. Help develop international policy and science and technology responses for sea dumped munitions programs.

Mission Statement

The International Dialogue on Underwater Munitions (IDUM) is a non-governmental organization/Society founded in 2004 by Mr. Terrence P. Long following his appearance at a Canadian Senate Hearing with the Senate Standing Committee on Fisheries and Oceans. The IDUM’s mission is to promote the creation of an internationally binding treaty on all classes (biological, chemical, conventional, and radiological) of underwater munitions. This treaty would encourage countries to collaborate on underwater munitions policy, research, science, and responses including environmentally-friendly remediation in affected regions. The IDUM is an internationally recognized body where all stakeholders (diplomats,
government departments including external affairs, environmental protection and fishery departments, industry, fishermen, salvage divers, oil and gas, militaries and others) can come together in an open and transparent forum to discuss underwater munitions, seek solutions, and promote international teamwork on their issues related to underwater munitions. The IDUM promotes constructive engagement with all stakeholders rather than disengagement so that we may learn from one another’s situation and determine how we can best respond in the future with everyone’s considerations. What we have learned is that off-the-shelf-technology, developed by the oil and gas industry and military’s unmanned systems programs, does exist to address underwater munitions sites. And there is a “Need to clean” based on the potential human health and environmental impact on our health care systems and fish stocks. Underwater munitions in some form or another will continue to pollute the marine environment over time. It’s just a question of “When”. Underwater Munitions are “Point Source Emitters of Pollution”. In most cases, remove the source and you remove the problem.

Chairman’s Message

“The IDUM is collaborating with international leaders and organizations to better understand the socio-economic impact on both human health and environment from years of decaying underwater munitions. The organization is facilitating this through international diplomacy via national and international programs, dialogues, conferences, workshops, committees, senate hearings, and international commissions. Most notable are the international efforts of the Government of Lithuania that resulted in the unanimous passing of the United Nations Resolution on Sea Dumped Chemical Weapons in December 2010 at the United Nations. Internationally, we must organize and continue our work together to collect, process, and provide information on underwater munitions to the Secretary General of the United Nations in 2013. Any tangible approach would require a multilateral response from all stakeholders including institutional capacity-building and the creation of an International Donor Trust Fund.”
