Directory Structure:
/kn166_11/README.txt - This file with format description.
/kn166_11/ladcp/ladcp_vm_dt - Processed final LADCP absolute velocity data and profile plots.
/kn166_11/ladcp/ladcp_raw - Raw binary LADCP data.
/kn166_11/ladcp/ladcp_setup - Setup files for processing LADCP data.
/kn166_11/ladcp/ctdladcp - CTD time series files for LADCP processing.
/kn166_11/vmadcp/pingdata - Raw binary VMADCP data.
/kn166_11/vmadcp/kn166_vmadcp_all.mat - Processed final VMADCP absolute velocity data.
/kn166_11/vmadcp/meandiff_B.dat - On-station average VMADCP data.

Data Format:
/kn166_11/ladcp/ladcp_vm_dt - Processed final LADCP absolute velocity data and profile plots.
All velocities are in m/s.
1. Depth (m)
2. U
3. V
4. U (vm referenced*)
5. V (vm referenced*)
6. U (vm ref, detided**)
7. V (vm ref, detided**)

* LADCP profile referenced to on-station averaged 
  shipboard adcp data 100 - 300 m. depth.

** Shipboard adcp referenced LADCP profile detided 
   using barotropic arctic model (5 km resolution)

model_depths.eps - Comparison of station depths with 
   depths used in tidal model. The model calculates 
   velocity by dividing transport by depth. If the 
   depth it uses is way off, the tides at that location 
   are more suspect. 

/kn166_11/ladcp/ladcp_raw - Raw binary LADCP data.
Raw data collected using a RD Instruments 150 khz Broadband ADCP.

/kn166_11/ladcp_setup - Setup files for processing LADCP data.
### = Station number.
ks###_gopro.m - Matlab command file for preparing data for processing.
                CTD, GPS, and LADCP data are merged.
ks###.inf - Input file for processing data. Contains start and end 
            times and position.

/kn166_11/ladcp/ctdladcp - CTD time series files for LADCP processing.
ks###.scl - CTD time series files.
Columns:
1. Pressure (dbars)
2. Temperature (deg C)
3. Salinity (psu)
4. Sound velocity (m/s)
5. Time (elapsed seconds)

/kn166_11/vmadcp/pingdata - Raw binary VMADCP data.
Raw data collected using a RD Instruments 150 khz Narrowband ADCP.

/kn166_11/vmadcp/kn166_vmadcp_all.mat - Processed final VMADCP absolute velocity data.
Processed using Univ. of Hawaii CODAS package.
