Double MOCHA: Phase II Multi-study Ocean acoustic Human effects Analysis
Abstract
The overall objective of this project is to develop new quantitative models and analytical methods for inferring behavioral response of marine mammal species to Navy sonar. The results will be directly applicable to current Behavioral Response Studies (BRSs) operating on multiple species in multiple oceans and will support future Navy behavioral response criterion development. Three specific objectives are as follows. 1) Develop analytical methods for estimation of behavioral response and subsequent recovery from controlled exposure experiments (CEEs) that allow fusion of multiple input datasets collected across a range of spatial and temporal scales. A particular emphasis will be on the multi-scale Atlantic BRS study. 2) Develop recommendations for effects analysis of long-term passive acoustic data. The work will support effects analysis of vocal marine mammals by both Atlantic and Pacific fleets, as well as BRS studies that deploy long-term passive acoustic sensors. 3) Develop next-generation models for behavioral response based on our understanding of marine mammal signal detection and evolutionary drivers of response. This will have longer-term impact on exposure-impact modelling and future BRS design. We also list further objective as an option. Option 1) Develop flexible and practical methods for dose-response that allow data from multiple species to be combined and different functional forms of the dose-response function to be fit. This will facilitate development of improved noise exposure criteria, and hence support future Navy behavioral response criterion development.
