  1. Profiling Dissipation Measurements using χpods on Moored Profilers in Luzon Strait fast thermistors on APL MP 2 pointed up 2 pointed down Preliminary Tests Puget Sound December 2009 refinements IWISE 2010 Deployment mooring MPN July 2010 IWISE 2011 Deployment moorings N1, N2 Moum (OSU) Perlin (OSU) Nash (OSU) Alford (APL/UW)

  2. Profiling Dissipation Measurements using χpods on Moored Profilers in Luzon Strait spectrum fit to theoretical form defines χ data example Kraichnan theoretical spectrum εχ=N2χ/2ΓTz2

  3. Profiling Dissipation Measurements using χpods on Moored Profilers in Luzon Strait depth variations / 200 m vertical averages mooring N2 local KE 1150-1750 m ε image plot constructed from daily-averaged profiles

  4. New mean speed / dissipation sensor for use on χpods and in general on moorings inexpensive,lightweight, low power, standalone velocity sensor χpod mooring N1 – χpod at 2000 m 1 day time series dissipation sensor at high f speed sensor at low f full characterization of sensor including wind tunnel tests are ongoing ε=2x10-7 m2s-3
