Brief communication: The challenge and benefit of using sea ice concentration satellite data products with uncertainty estimates in summer sea ice data assimilation [PDF]
The Cryosphere, 2016 Data assimilation experiments that aim at improving summer ice concentration and thickness forecasts in the Arctic are carried out. The data assimilation system used is based on the MIT general circulation model (MITgcm) and a local singular evolutive ...

Vertical ocean heat redistribution sustaining sea-ice concentration trends in the Ross Sea. [PDF]
Nat Commun, 2017 Several processes have been hypothesized to explain the slight overall expansion of Antarctic sea ice over the satellite observation era, including externally forced changes in local winds or in the Southern Ocean’s hydrological cycle, as well as ...

Concentric Joints in Ice [PDF]
Nature, 1912 IN walking over a piece of water-logged ground, I noticed several small shallow pools which had frozen over. A number of rings, more or less parallel to the edges, were visible as in the plan. The water was found to be a couple of inches below the top of the ice, and the rings were vertical planes, along which the ice could be readily broken.
