A one-dimensional thermodynamic model of sea ice is presented that includes the effects of snow cover, ice salinity, and internal heating due to penetration of solar radiation. The incoming radiative and turbulent fluxes, oceanic heat flux, ice salinity, snow accumulation, and surface albedo are specified as functions of time. The model is applied to the central Arctic.read more

Using sea ice to measure vertical heat flux in the ocean
TL;DR: In this paper, an experiment performed at drifting ice station FRAM I in the Arctic Ocean northwest of Spitzbergen during March-May 1979 indicate that sensible heat flux from the ocean to the ice cover was less than 2 W m−2.

A Thickness and Enthalpy Distribution Sea-Ice Model
Jinlun Zhang,D. A. Rothrock +1 more
TL;DR: The theory of sea ice thickness distribution developed by Thorndike et al. as discussed by the authors has been extended to include sea ice enthalpy distribution, which conserves both ice mass and thermal energy, in the form of the heat stored in the ice.

Arctic Sea ice decay simulated for a CO2-induced temperature rise
TL;DR: A large scale numerical time-dependent model of sea ice that takes into account the heat fluxes in and out of the ice, the seasonal occurrence of snow, and ice motions has been used in an experiment to determine the response of the Arctic Ocean ice pack to a warming of the atmosphere as discussed by the authors.

The role of large‐scale under‐ice topography in separating estuary and ocean on an arctic shelf
TL;DR: In this paper, measurements of salinity and δ18O both from ice cores and the water column are used to infer the separation into two convective regimes due to the under-ice topography of the system of large pressure ridges that forms at the boundary between landfast ice and pack ice.

Arctic Ocean freshwater: How robust are model simulations?

TL;DR: In this article, a comparison of the hindcasts from ten ocean-sea ice models shows that the simulation of the Arctic freshwater (FW) budget is quite different in the investigated models, and the best model-to-model agreement is found for the interannual and seasonal variability of the liquid FW export and the solid FW storage, which also agree well with observations.

On the mass and heat budget of arctic sea ice
TL;DR: In this article, the authors show that during the summer seasons 1957 and 1958, an amount of 19.2 and 41.4 g/cm2 was lost by surface ablation on elevated dry surface and in meltwater ponds, respectively.
