Wave rafting and the equilibrium pancake ice cover thickness

Out of Equilibrium? The World’s Changing Ice Cover

Wave scattering by an ice sheet of variable thickness

This paper describes an investigation into the effect on wave propagation of an ice sheet of varying thickness floating on water of varying depth. A variational principle equivalent to the governing equations of linear theory in three dimensions is given, forming the basis of a Rayleigh-Ritz approximation. Here we invoke the mild-slope approximation in respect of the ice thickness and water dep...

Recent Variability in Sea Ice Cover, Age, and Thickness in the Pacifi c Arctic Region

J.M. Grebmeier and W. Maslowski (eds.), The Pacifi c Arctic Region: Ecosystem Status and Trends in a Rapidly Changing Environment, DOI 10.1007/978-94-017-8863-2_3, © Springer Science+Business Media Dordrecht 2014 Abstract Over the past several decades, there has been a fundamental shift in sea ice cover, age, and thickness across the Pacifi c Arctic Region (PAR). Satellite data reveal that tren...

Dispersal of marine benthic invertebrates through ice rafting.

Knowledge of dispersal vectors used by organisms is essential to the understanding of population and community dynamics. We report on ice rafting, a vector by which intertidal benthic invertebrates can be transported well outside their normal dispersal range during winter in temperate climates. We found multiple invertebrate taxa in sediment-laden ice blocks sampled in the intertidal zone. A la...
