Acoustics. 9/11/12. UP vs Down looking ADCP ( remus 3). Note: depth not exactly correct but this is good for visual inspection. Time vs Depth (all 80 bins). Time vs Depth (only 20 bins=5m). Time vs Depth (lines at 5m & max Up depth). Time vs Depth . Green: start inflection

Presentation Transcript

  1. Acoustics 9/11/12

  2. UP vs Down looking ADCP (remus 3)

  3. Note: depth not exactly correct but this is good for visual inspection Time vs Depth (all 80 bins)

  4. Time vs Depth (only 20 bins=5m)

  5. Time vs Depth (lines at 5m & max Up depth)

  6. Time vs Depth Green: start inflection Red: end inflection. Find deepest UP adcp depth for each down and upinflection. Ex. in box And remove data below that depth.

  7. Area in box- not associated with an inflection. Do I remove data like this? (Typically at the start and end of each mission)

  8. Time vs Depth On Downward looking ADCP- remove everything deeper than max Up depth.

  9. Time vs. Depth (Eliminate upper 5m)

  10. Compare acoustics to CHL

  11. Krill below CHL? Krill? Krill?
