In the report, we tried to go through concepts and organization of the database to provide an understanding of the system. Details of operation of the INMAGIC program itself have been left to the instruction manual which accompanies the software. The report includes information on getting started using the INMAGIC program with the literature database, on organization of the database, and on print formats useful with the reference data. The species list and subject lists are those that we now use for work on the database. Note that this is a very comprehensive database management system that permits sorting, searching, …

The 20-Hz Signals Of Finback Whales (Balaenoptera Physalus), William Watkins, Peter Tyack, Karen Moore, James Bird
James E Bird
The 20-Hz signals of finback whales (Balaenoptera physalus) were analyzed from more than 25 years of recordings at a variety of geographic locations on near-surface hydrophones close to whales and on deep hydrophone systems. These signals were composed of 1-s pulses of sinusoidal waveform with downward sweeping frequency from approximately 23 to 18 Hz at variable source levels up to 186 dB (re: 1 microPa at 1 m), usually with slightly lower levels for the pulses at the beginning and end of sequences. These "20-Hz" pulses were produced in signal bouts (separated by more than 2 h) lasting as long …
