SUMMARY:Damping of surface wave in MIZ of the Barents Sea: field observati

DESCRIPTION:Presentation will include an overview of field measurements of
  waves performed from drift ice in the Barents Sea since 2006. It includes
  observations of ice motion during events of wave propagation\, measuremen
 ts of sea current velocities in under ice boundary layer\, water pressure 
 at different depths\, accelerations and angular velocities of floes. The d
 ata are used for the calculation of dispersion properties of observed wave
 s and characteristics of under ice turbulence. The coefficient of wave att
 enuation is calculated using equation of floe motion along the water surfa
 ce with relatively common assumptions about floe-floe interactions and kno
 wn solution describing oscillating boundary layer near the bottom of float
 ing ice. Numerical values of the coefficient are reconstructed using the d
 ata of field measurements. The evolution of wave spectra in MIZ of the Nor
 th-West Barents Sea is compared with the wave spectra calculated from the 
 high resolution satellite image (SAR).
