The filename itself is intended to give some brief identifying information
to the user.  "AO1" refers to the mooring, "82" refers to the instrument
depth in meters, "90" refers to the year, and "rcm" indicates that this
was a recording current meter. 

Within the file itself, the line beginning with '%' is a file header
intended to give users a brief history of what collected the data, where,
and when.

It can be broken down as follows:

AO1-90              = mooring designation (mooring-year)
6544                = serial number used to reference our database
72.620              = latitude (north)
-143.568            = longitude (west)
82                  = instrument depth in meters
3339                = bottom depth in meters
902470300           = starting year, julian day, and hour of first good
                      record
920041500           = ending year, julian day, and hour of last good
                      record 
CM4                 = type of instrument - Aanderaa current meter


The next row describes the contents of each column individually:

yr      jd      gmt     temp    --      --      dir     spd     rec

where    yr    = year
         jd   = julian day
         gmt   = hour in GMT
         temp  = water temperature in degrees celsius
         --    = indicates that a particular device was not working and
                 the data in that column are all zeroes
         dir   = current direction with zero degrees being true north
         spd   = current speed in centimeters per second
         rec   = a sequential index

Again, the filename itself is intended to give some brief identifying
information to the user.  "AO1" refers to the mooring, "83" refers to the
instrument depth in meters, "90" refers to the year, and "tsr" indicates
that this was a temperature-salinity recorder.

The file header can be broken down as follows:

AO1-90              = mooring designation (mooring-year)
263                 = serial number used to reference our database
72.620              = latitude (north)
-143.568            = longitude (west)
83                  = instrument depth in meters
3339                = bottom depth in meters
902470300           = starting year, julian day, and hour of first good
                      record
921130100           = ending year, julian day, and hour of last good
                      record 
TSR                 = type of instrument - Seabird SBE-16 (Seacat)


The next row describes the contents of each column individually:

yr      jd      gmt     temp    cond    press   saln    rec


where    yr    = year
         jd    = julian day
         gmt   = hour in GMT
         temp  = water temperature in degrees celsius
	 cond  = conductivity in Siemens/m
	 press = pressure in db
	 saln  = salinity in ppt
         rec   = a sequential index



I should mention that for each file, we have decided to include 12 lines
before each 'first good record', and 12 lines after each 'last good
record'.  This is an attempt to give the user a frame of reference for the
data, rather than abruptly begin and end the data set with first and last
good records. 

If you have any questions, or require further identifying information,
please do not hesitate to contact me. 

Thanks,
-Mark
