JIP Phase 1 made a thorough survey of knowledge gaps on sound sources and acoustic effects on animals. JIP Phase 2 re-named these knowledge gaps Research Topics, and used them to seek proposals from 2006 to 2008. New developments in science during those years have modified the list of Research Topics somewhat. The current list appears below in five broad Research Categories. The numbers applied to Research Categories and Research Topics are for ease of reference only and do not imply prioritisation. The JIP does not accept proposals on any Research Topic at any time. It uses Requests for Proposals to announce the Research Topics it intends to consider at any one time.
Detailed information on characteristics of sound sources and improved models of sound transmission and propagation.
Greater understanding of the potential impacts of sound sources on the hearing ability of animals, stress, and direct damage to auditory and non-auditory tissues (such as lungs or fish eggs).
Effects of sound on behaviour (including communication, foraging, migration, reproduction and predator avoidance), auditory factors that affect behaviour (including perception, sensitivity, and auditory masking), and the Biological Significance (population-level effects) of these changes including long-term cumulative effects and synergisms with non-acoustic stressors.
Develop alternative sound sources or operating procedures, evaluate or improve existing mitigation measures or develop new mitigation measures that would lessen the risk of acoustic impacts on marine animals.
Need for new or updated equipment or techniques to improve research data collection or monitoring efficacy:
