Task 4b

Estimating cue rate from proxy data

In some cases, direct information about acoustic cue production rate might not be available. However, some variables available from non-acoustic tags (for example behavioural state) may correlate with cue rates, and hence be potentially useful for estimating acoustic cue rate. Once such model is developed, it can also be used to estimate behavioral states in tag data without acoustic sensors and make inferences on cue rate based on those estimated states. Datasets for 3 species (sperm whale, Cuvier’s beaked whale and narwhal) have been identified for this task. There might be other historical datasets, where non-acoustic information might be used to derive cue rate estimates, along the lines described above. If such datasets are identified under task 1 we might extend task 4b to them.
