A two layer model for wave dissipation in sea ice [PDF]
arXiv, 2018 Sea ice is highly complex due to the inhomogeneity of the physical properties (e.g. temperature and salinity) as well as the permeability and mixture of water and a matrix of sea ice and/or sea ice crystals. Such complexity has proven itself to be difficult to parameterize in operational wave models.

Sea Ice Brightness Temperature as a Function of Ice Thickness, Part II: Computed curves for thermodynamically modelled ice profiles [PDF]
arXiv, 2012 Ice thickness is an important variable for climate scientists and is still difficult to accurately determine from microwave radiometer measurements. There has been some success detecting the thickness of thin ice and with this in mind this study attempts to model the thickness-radiance relation of sea ice at frequencies employed by the Soil Moisture ...

Airborne electromagnetic sea ice thickness sounding in shallow, brackish water environments of the Caspian and Baltic Seas [PDF]
, 2006 Ice engineering projects often rely on the knowledge of ice thickness in shallow, brackish water like in the Baltic and Caspian Seas. By means of field data and model results, the paper shows that helicopter-borne electromagnetic induction measurements ...

Advanced Functional Materials, EarlyView.Novel conjugated polymers with side‐chain π‐conjugation are developed to enhance organic thermoelectric properties. Remarkably, the pendant doping in the conjugated polymers preserved strong intermolecular ordering in the film states even at high FeCl3 dopant concentrations (16 – 32 mM), achieving a promising power factor > 10 µW m−1 K−2 across a wide ...
