The files in this directory contain time series of measurements from 
inverted echo sounders.  Each file contains a header portion and a 
data portion.  The header portion contains the following information; 

 - Experiment name
 - Site name
 - Serial number of the instrument
 - Mooring latitude (in decimal degrees North)
 - Mooring longitude (in decimal degrees East)
 - Nominal mooring depth (in meters)
 - Deployment Year, month, and day
 - Recovery Year, month, and day

The lines of header information all begin with a percent sign (%).  


The data segment of the file contains the following seven columns; 

 - Year
 - Month
 - Day
 - Hour 
 - Minute 
 - Second
 - Measured travel time (in seconds)

The measured travel times are accurate to approximately 0.001 seconds.
