  1. Results from Four Fall Rate Experiments Derrick Snowden, Molly Baringer and Gustavo Goni

  2. Cruise Locations rb98: 79 rvyf: 427 (6 systems) nf0705: 10 pne07: 18

  3. PNE07 XBT/CTD Profiles

  4. PNE07 XBT/CTD Profiles

  5. Determining Depth Offset Focus on the temperature gradient: derivative of temperature with respect to depth Minimize temperature error effect

  6. Depth Offset Prior to Correction

  7. Depth Correction Algorithm • Assemble the depth offsets (dZ) • Recalculate XBT depths Znew = Zxbt+dZ • Back calculate time (t) • Fit new fall rate equation to (t) z = at^2 + bt + c

  8. Depth Offset: Post-Correction

  9. Depth Offset Prior to Correction
