Wave-in-ice: theoretical bases and field observations
1Department of Civil and Environmental Engineering, Clarkson University, Potsdam, NY 13699, USA.
Summary
This study reviews wave-ice interaction theories, highlighting distinct physical processes like scattering and damping. Field data suggest a multi-physics approach is needed for accurate wave attenuation modeling in icy conditions.
Area of Science:
- * Physical Oceanography
- * Sea Ice Physics
Background:
- * Growing research interest in wave-ice interactions over recent decades.
- * Existing theories model wave dispersion and attenuation through distinct physical processes.
- * Four primary processes considered: scattering, flexural damping, viscoelastic damping, and basal friction.
Purpose of the Study:
- * To investigate and compare different physical processes influencing wave dispersion and attenuation in ice.
- * To analyze the mathematical formulations and low-frequency behaviors of existing wave-ice theories.
- * To discuss the role of field observations in validating and calibrating these theories.
Main Methods:
- * Review and analysis of representative theories on wave-ice interactions.
- * Examination of mathematical models for scattering, flexural damping, viscoelastic damping, and basal friction.
- * Discussion of uncertainties in field measurements for wave attenuation estimation.
Main Results:
- * Different theories yield fundamentally different spectral attenuation behaviors, especially at low frequencies.
- * Field observations provide data for calibrating and validating theoretical models.
- * Current theories often focus on single physical processes, leading to discrepancies.
Conclusions:
- * A multi-physics approach is recommended for wave-in-ice modeling, supported by observational data.
- * Further theoretical development is necessary to improve wave-in-ice model performance.
- * Achieving open-ocean wave model performance requires integrated theoretical, modeling, and observational efforts.

02:39Phase Transitions: Melting and Freezing
12.7K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

01:07Propagation of Waves
2.4K
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

26.1K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

01:07Reflection of Waves
3.9K
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...

02:12The Wave Nature of Light
49.8K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

01:07Interference and Superposition of Waves
5.4K
When two waves of the same nature occur in the same region simultaneously, they result in interference. Interference of waves implies that the net effect of the waves is the sum of the individual waves' effects. However, it does not imply that the individual waves affect the propagation of other waves.
Interference occurs in mechanical waves, such as sound waves, waves on a string, and surface water waves. Mechanical waves correspond to the physical displacement of particles. Hence,...
