OC3570 Operational Oceanography

• Comparison of ADCP Velocities
• LT Mike Rost
• 17 March 2004

ADCP (ology)

• Frequency and resolution
• Narrow Band vs Broadband
• Who is this Doppler guy?
• Gates and Bins (its a round up)
• Independence

Distance from Central Point

Interpreting the Data

• TRBM was vector averaged into equal size bins
  with same center depth as VADCP
• TRBM was time averaged to 5 minute increments to
  match VADCP data.
• TRBM is up pointing vs VADCP down pointing nature
