There has been a significant increase of studies on wave-ice interactions in the past decades. Through a close look at a representative set of theories, this paper investigates different physical processes that have produced different wave dispersion and attenuation. The existing theories have considered four major processes: scattering, flexural damping, viscoelastic damping and basal friction. Each theory looked into one of these processes and used a different mathematical formulation to model these processes. The low-frequency behaviours of the resulting spectral attenuation in these theories are fundamentally different from each other. Recent field observations have produced a large amount of data to calibrate and validate these theories. The uncertainties in using field measurements to determine attenuation due to ice covers are discussed. Both observational data and applications of these theories in field conditions suggest a multi-physics approach. A number of studies to further the theoretical development are recommended. It will take time for wave-in-ice models to reach the same level of performance as wave models for the open ocean, relying on the combined effort of theoretical, modelling and observational studies. This article is part of the theme issue 'Theory, modelling and observations of marginal ice zone dynamics: multidisciplinary perspectives and outlooks'.
在过去几十年里，关于波浪与海冰相互作用的研究显著增加。通过仔细研究一组具有代表性的理论，本文探讨了产生不同波浪色散和衰减的各种物理过程。现有理论考虑了四个主要过程：散射、弯曲阻尼、粘弹性阻尼和底部摩擦。每种理论都研究了其中一个过程，并使用不同的数学公式对这些过程进行建模。这些理论中所得频谱衰减的低频行为彼此存在根本差异。最近的实地观测产生了大量数据，用于校准和验证这些理论。讨论了使用实地测量来确定冰盖引起的衰减时的不确定性。观测数据以及这些理论在实地条件下的应用都表明需要采用多物理方法。建议开展一些进一步推动理论发展的研究。波浪-海冰模型要达到与开阔海洋波浪模型相同水平的性能还需要时间，这依赖于理论、建模和观测研究的共同努力。本文是主题特刊“边缘冰区动力学的理论、建模与观测：多学科视角与展望”的一部分。
