Getting in the thick of Antarctic ice – experts respond

John Kerr posted in on November 25th, 2014.

Sea ice in the Antarctic may be thicker than previously thought, according to a study published online in Nature Geoscience. Although the aerial extent of Antarctic sea ice is easily tracked by satellites, estimating the thickness of the ice from above has proven challenging. Researchers from Australia, the US and the UK used an autonomous […]

Storm waves a factor in sea ice retreat

Large waves generated by ocean storms have a greater impact on the breakup and retreat of sea ice than previously thought. New research from NIWA, published this week in Nature, suggests that large ocean waves whipped up by storms can fracture Antarctic sea ice hundreds of kilometres from the ice edge and accelerate sea-ice retreat.
