SIPW02 - Ice-fluid interaction

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, measurements of sea current velocities in under ice boundary layer, water pressure at different depths, accelerations and angular velocities of floes. The data are used for the calculation of dispersion properties of observed waves and characteristics of under ice turbulence. The coefficient of wave attenuation is calculated using equation of floe motion along the water surface with relatively common assumptions about floe-floe interactions and known solution describing oscillating boundary layer near the bottom of floating ice. Numerical values of the coefficient are reconstructed using the data of field measurements. The evolution of wave spectra in MIZ of the North-West Barents Sea is compared with the wave spectra calculated from the high resolution satellite image (SAR).
