Antarctic minke whale acoustic data
Acoustic signaling is the predominant form of communication among cetaceans. Understanding the behavioral state of calling individuals can provide insights into the specific function of sound production; in turn, this information can aid the evaluation of passive monitoring data sets to estimate spe...
