Corrugation Ridges

A team of scientists mapped more than 7,600 small-scale landforms called ‘corrugation ridges’ across the seafloor near Norway.

  • The corrugation ridges found are less than 2.5 m high and are spaced between about 25 and 300 metres apart.
  • These landforms are understood to have formed when the ice sheet’s retreat.
  • Formation - The retreating margin of the ice sheet moved up and down with the tides, pushing seafloor sediments into a ridge every low tide.
  • Two ridges would have been produced each day (under 2 tidal cycles per day),
  • Retreating Rate - The researchers were able to calculate how quickly the ice sheet retreated from the number of ridges formed.
  • Their results show the former ice sheet underwent pulses of rapid retreat at a speed of 50 to 600 metres per day.
  • This is the fastest ice sheet retreat that has been ever observed from satellites or inferred from similar landforms in Antarctica.
