... examines the relationships between target range (R), click intervals,and source levels of wild bottlenose dolphins ( Tursiops sp.) by recording regular (non-buzz) echolocation clicks with a linear hydrophone array. Dolphins clicked faster with decreasing distance to the array,reflecting a decreasing delay...
