32 st / June 2017 provided an important comparison for the capabilities of HOVs versus ROVs in these types of programs. Results from the final two field pro- grams are currently under review by the DOD and will be published when that review is complete. International Implications HUMMA produced an extremely large integrated data set, combining re- motely sensed (i.e., sonar, photograph- ic, chemical and environmental) data with physical samples of sediments, bi- ota and water, making it the most com- prehensive deepwater investigation of sea-disposed munitions undertaken in U.S. waters. The project addressed the potential impact of sea-disposed mu- nitions on the ocean and investigated best practices for assessing munitions at sea, demonstrating the effectiveness of a flexible, multiscale and multidisci- plinary approach. It is important to ac- knowledge that the extensive HUMMA data set still represents a small sample population relative to the number of disposed munitions in the area; never- theless, the results from HUMMA con- sistently show that dumped munitions at this site do not present a direct risk to humans. This approach is shared by Euro- pean initiatives, such as the European Union (EU) JPI Oceans joint action called "Munitions at Sea" (www.jpi-, where joint and coordinated transnational efforts aim at increasing the efficiency and effectiveness of interventions to emer- gencies, often adopted at national or local levels. In addition, there is the re- cently launched project DAIMON (De- cision aid for marine munitions) that proposes a risk management tool in the Baltic Sea region so that decision mak- ers can evaluate risks and benefits of various options in selected case sites. The legacy of sea disposal through- out the world is highly problematic. Disposal sites are characterized by uncertainties (e.g., unknown contents of many munitions, specific locations of disposal sites, degree of munitions casing corrosion, fate and transport of chemical agents) and a challeng- ing combination of broadly differing spatial and temporal scales that re- quires a state-of-the-art technologi- cal approach. Additionally, there is a geopolitical aspect to addressing sea- disposed munitions, often involving differing national regulations, which have hampered a global understanding of this important problem. Ultimately, the best approach for understanding the consequences of munitions disposed at sea will require a truly international effort to promote scientific advancements and tech- nological achievements. This is why members of the CHEMSEA (Chemical Munitions, Search and Assessment), a munitions project of the Baltic Sea re- gion financed by the EU Baltic Sea Re- gion Programme, and HUMMA teams collaborated on a joint publication of a Deep-Sea Research Part II special is- sue and have partnered at meetings to support an open dialog to address this global problem. In that spirit, ongoing activities involving munitions in Ha- waii will host observers from Europe in 2017 who will gain direct experience with the approaches and tools used to investigate munitions sea disposal in Hawaiian waters. ST Dr. Margo Edwards is a marine geophysicist and senior research scientist at the University of Hawaii (UH). She currently serves as interim executive director of the UH Applied Research Laboratory and as the interim director of the Hawaii Institute of Geophysics and Planetology in the UH School of Ocean and Earth Science and Technology. Ed- wards specializes in seafloor mapping using acous- tic and optical systems. She has served as the prin- cipal investigator of HUMMA since 2008. Dr. Sandro Carniel is a physical oceanographer and senior scientist at the Institute of Marine Sciences, Italian National Research Council (CNR-ISMAR, Venice, Italy), where he is currently the head of the oceanographic section. He is an expert in nu- merical modeling of coastal areas and turbulence measurements and is the prinicipal investigator and project leader in several international projects and cruises. He is leading the WP Science Support of the JPI Oceans Munitions at Sea project.
