Antarctica ‘gives ground to the ocean’

Scientists now have their best view yet of where Antarctica is giving up ground to the ocean as some of its biggest glaciers are eaten away from below by warm water.

Researchers using Europe’s Cryosat radar spacecraft have traced the movement of grounding lines around the continent.

These are the places where the fronts of glaciers that flow from the land into the ocean start to lift and float.

The new study reveals an area of seafloor the size of Greater London that was previously in contact with ice is now free of it.

The report, which covers the period from 2010 to 2016, is published in the journal Nature Geoscience.

“What we’re able to do now with Cryosat is put the behaviour of retreating glaciers in a much wider context,” said Dr Hannes Konrad from the University of Leeds, UK.

“Our method for monitoring grounding lines requires a lot of data but it means you could now basically build a permanent service to monitor the state of the edges of the continent,” he told BBC News.

  • @OP – Researchers using Europe’s Cryosat radar spacecraft have traced the movement of grounding lines around the continent.

    These are the places where the fronts of glaciers that flow from the land into the ocean start to lift and float.

    The new study reveals an area of seafloor the size of Greater London that was previously in contact with ice is now free of it.

    . . . and as ice continues to melt and sea levels continue to rise, the ice will float higher off the seabed, and more warm water will flow in to melt it from below! – breaking up the ice sheets which are holding back the land based ice in the glaciers on the slopes behind them, as the bergs float off into the tropical oceans to melt away – raising the sea levels even more!

    Meanwhile the denialists do not know what to measure, or how to measure, -aided by their political and media stooges, continue to pretend that it is glaciologists, meteorologists, oceanographers, geologists, climatologists, physicists, and space scientists, who cannot measure or produce historical records of changes!!
