چکیده
This study presents wave measurements in the Marginal Ice Zone (MIZ) obtained from ship mounted sensors. The system combines altimeter readings bow with motion correction data to provide estimated single point ocean surface elevation. Significant height and mean period, as well one-dimensional spectra are derived combined measurements. results compared integrated parameters two spectral models over a period of eight days open ocean, detecting instruments placed on ice floes inside MIZ. Mean absolute errors range 13.4-29.9% when comparing 1.0-9.6% valid instruments. spatial damping coefficient is by looking at change amplitude found discrete frequency values was moving along longitudinal direction MIZ within time intervals where field be approximately constant time. As expected theory, high waves effectively dampened presence sea ice. observed attenuation rates compare favourably two-layer dissipation model. Our methodology can regarded simple reliable way collect more waves-in-ice it easily added any participating expeditions, little extra cost.

Wave-Ice Interaction in the Marginal Ice Zone: Toward a Wave-Ocean-Ice Coupled Modeling System
The WAVEWATCH III model (Tolman 1991, Tolman et al. 2002, Tolman 2009) is a phase-averaged wave model solved by integrating the wave action conservation equation. Local rates of change of wave spectral density is determined by advection in four dimensions (two geographic and two spectral dimensions) and source terms representing various dynamic processes, such as energy transfer from the wind, ...

Our main objective is to improve an operational model for wind-generated surface gravity waves (WAVEWATCH III ®) such that it can accurately predict the attenuation and scattering of waves by interaction with ice in the Marginal Ice Zone (MIZ). The wave model physics developed here will later be part of an operational coupled model system, allowing feedback to ice, ocean, and atmospheric models...

Wave Climate and Wave Mixing in the Marginal Ice Zones of Arctic Seas, Observations and Modelling
The wind/wave climatology for the Arctic Seas will be developed based on altimeter observations. It will have a major scientific and applied significance as presently there is no reference climatology for this region of the ocean available. The new versions of wave models for the Beaufort and Chukchi Seas will include new physics that is already under development, and the novel physics presentl...
متن کاملModelling wave-induced sea ice break-up in the marginal ice zone
A model of ice floe break-up under ocean wave forcing in the marginal ice zone (MIZ) is proposed to investigate how floe size distribution (FSD) evolves under repeated wave break-up events. A three-dimensional linear model of ocean wave scattering by a finite array of compliant circular ice floes is coupled to a flexural failure model, which breaks a floe into two floes provided the two-dimensi...
