The archived files in this website directory contain wave and current data collected
with an RD Instruments 1200 KHz ADCP (Acousitc Doppler Current Profiler)
located approximately 670 meters offshore of Spessard Holland Park in Melbourne Beach, FL. 
The total water depth at the gauge is approximately 8 meters.  The wave, current, and tide
data sampling interval is 20 minutes every 2 hours.  

There are two file formats in this directory.  Files archived before September 2002 have 
a single average value for current speed and direction.  Files after September 2002 
have 5 measurements of current speed and direction equally distributed over the water
column.

___________________________________________________________________________________________
The first few lines of the pre-September 2002 files are typically as follows:  

Hs in m, Tp in sec, Dp in deg, Depth in m

 yr  mo  da  hr  mn  sc  Hs    Tp    Dp  Depth     CM       CD
 1  10  03  11  00  00  0.82 10.6   53   8.136    0.148    173
 1  10  03  13  00  00  0.70 10.6   77   7.637    0.153    181
 1  10  03  15  00  00  0.67 11.6   77   7.361    0.142    188

The first six columns are the time stamp which indicates the time at the start of each 
data collection period.  This is local time (EDT).
(yr,mo,da,hr,mn,sc = year, month, day, hour, minute, second)

The remaining columns are the measured data. 
Hs = significant wave height (meters) 
Tp = peak wave period (seconds)
Dp = peak wave direction (degrees from magnetic North) (waves come from this direction)
Depth = water depth above the gauge (add 1.5m to get total water depth) 
CM = depth averaged current speed (meters/sec) 
CD = depth averaged direction toward which the current flows (in degrees from Magnetic North)

The first few lines of the post-September 2002 files are typically as follows:

The first column (n) is the sample number, which has no relevance in this archive.

The next seven columns are the time stamp which indicates the time at the start of each 
data collection period.  This is local time (EDT).
(year, month, day, hour, minute, second, thousandths of seconds)

The remaining columns are the measured data. 
Hs = significant wave height (meters) 
Tp = peak wave period (seconds)
Dp = peak wave direction (degrees from magnetic North) (waves come from this direction)
Depth = water depth above the gauge (add 1.5m to get total water depth) 
number of current measurement bins = 5 (this format will always have 5 bins)
CM1 = current speed in bin 1 located just above the gauge or approx 2 meters from the sea floor.
CD1 = current direction in bin 1 (in degrees toward which the current travels relative to magnetic North)
CM2 = current speed in bin 2 (located above bin 1)
CD2 = current direction in bin 2 
etc....
bin 5 is the bin closest to the surface.  Bin sizes vary due to changes in water depth.
