The table below allows anyone to visually browse spectrograms generated from the MARS hydrophone data.  Simply select the month and year of interest, and all of the hourly spectrograms for that month will be loaded into the viewing panel. The visual browsing does not produce sound; to hear recordings, please visit our Listening Room.

Animation controls are located below the spectrogram viewing panel. You can scroll forward in time (>) or backward (<);  stop scrolling ([]); step forward by one hour at a time (+1) or backward (-1); or restart from the beginning of month (START).
