As done so successfully in the previous years, this session focuses on research and development in nuclear explosion monitoring. We welcome contributions regarding all aspects of detecting, locating and characterizing nuclear explosions and releases and their aftermath in all relevant fields of research, including seismology, infrasound, hydroacoustics, nuclear physics and atmospheric backtracking. Papers may address, inter alia, research on algorithms, uncertainty analysis, new and historic data, data collection, machine learning and data mining, experiments and modeling. We also strongly encourage submitting work on the integration (fusion) of monitoring data from relevant technologies.
