Using Nonlinear Time Sampling Of Bowhead Whale Calls To Extract Acoustic Mode Shape And Array Tilt
International audience Conventional passive acoustic tracking techniques require the deployment of multiple instrument packages over wide areas, an expensive and time-consuming process. In 2010 and 2012 a 15-element vertical array was deployed in conjunction with Shell's passive acoustic marine...
