Physical Drivers of Ocean Wave Attenuation in the Marginal Ice Zone

چکیده
Abstract Despite a recent resurgence of observational studies attempting to quantify the ice-induced attenuation ocean waves in polar oceans, physical processes governing this phenomenon are still poorly understood. Most analyses have attempted relate spatial rate wave frequency, but not considered how relationship depends on ice, wave, and atmospheric conditions. An in-depth analysis wave-buoy data collected during 2017 Polynyas, Ice Production, Seasonal Evolution Ross Sea (PIPERS) program is conducted. Standard techniques used estimate ? , influence number potential drivers its dependence period T investigated. A power law shown consistently describe ( ) relationship, line with other analyses. The two parameters describing found depend significantly sea ice concentration, mean period, wind direction, however. Looking at cross correlations between these drivers, three regimes identified, which characterize different conditions, very possibly causing observed attenuation. This suggests that parameterizations decay spectral models should be piecewise, so as include their local Significance Statement work attempts conditions oceans affect way result interactions ice. In situ analyzed along several freely available datasets. simple due across all analyzed. However, affected by direction. finding large-scale need account for improve forecast ice-covered oceans.

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...

Modelling 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...
متن کاملGranular flow in the marginal ice zone.
The region of sea ice near the edge of the sea ice pack is known as the marginal ice zone (MIZ), and its dynamics are complicated by ocean wave interaction with the ice cover, strong gradients in the atmosphere and ocean and variations in sea ice rheology. This paper focuses on the role of sea ice rheology in determining the dynamics of the MIZ. Here, sea ice is treated as a granular material w...
