presence and seasonal variation of deep diving foraging odontocetes around kauai, hawaii using remote autonomous acoustic recorders.ecological acoustic recorders (ears) were moored off the bottom in relatively deep depths (609-710 m) at five locations around the island of kauai. initially, the ears had an analog-to-digital sample rate of 64 khz with 30-s recordings every 5 min. after the second deployment the sampling rate was increased to 80 khz in order to better record beaked whale biosonar signals. the results of the 80 khz recording are discussed in this manuscript and are the results of three deployments over a year's ...201424437792
