Antarctic ice thicker than previously thought, study finds

First of its kind robotic survey of underside of sea ice floes reveals denser ice fringing the continent


24 November


Groundbreaking 3D mapping of previously inaccessible areas of the Antarctic has found that the sea ice fringing the vast continent is thicker than previous thought.

Two expeditions to Antarctica by scientists from the UK, USA and Australia analysed an area of ice spanning 500,000 metres squared, using a robot known as SeaBed.

The survey discovered ice thickness average between 1.4m and 5.5m, with a maximum ice thickness of 16m. Scientists also discovered that 76% of the mapped ice was ‘deformed’ – meaning that huge slabs of ice have crashed into each other to create larger, denser bodies of ice.

The team behind the research, published in Nature Geoscience, have hailed it as an important breakthrough in better understanding the vast icy wilderness. The findings will provide a starting point to further work to discover how ice thickness, as well as extent, is changing.

Previously, measurements of Antarctic ice thickness were hindered by technological constraints. Ice breaking ships could only go so far into ice to measure depth, while no-one had drilled much more than 5.5m down into the ice to extract a core for analysis.

Now the leftists instead of showing poor polar bears on tiny pieces of ice floating away to oblivion. Are now going to have headlines with a picture of a polar bear looking frustrated and sad because global warming has made the ice so thick that the poor bear can't get through the ice to get to the water. :lol:
