Summary

• Weekly transmission loss fields over an eighteen month period

• Wide range of frequencies and operating depths

  • Frequency range: 20 to 5000 Hz
  • Operating depth range: 50 to 1500 feet

• MIV provides a detailed and realistic representation of the ocean acoustic environment

• For JWARS, MIV has provided a time varying passive acoustic environment for East Asia and Southwest Asia

• APL is currently addressing MIV-based data to support active acoustic ASW for JWARS

• Future: possible application of MIV to other propagation domains such as radar and chemical/biological dispersion
