Pressure Ridge

Changing sea-ice regimes will also affect pressure-ridge development, which will change under-ice circulation, but the direction of change is uncertain. ❋ Unknown (2009)

Securely roped together we made our way down, until our progress was stopped by a huge pressure-ridge, which, as far as could be made out, formed the boundary between land and sea-ice. ❋ Unknown (2009)

Sea-ice pressure-ridge keels and icebergs scour the seabed, resulting in a characteristic roughened or ploughed seabed morphology that may affect resuspension rates and could change the degree of consolidation of the seabed surface. ❋ Unknown (2009)

The creature was loping along behind him, dodging the same jagged seracs and pressure-ridge slabs that Blanky was clumsily slaloming around in the dark. ❋ Simmons, Dan (2007)

Goodsir looked out at the cracking, shifting, pressure-ridge surging ice jumble stretching south below low, grey snow clouds. ❋ Simmons, Dan (2007)

I suppose it was an old crevasse filled with soft snow, or perhaps one of the pressure-ridge hollows which had been recently drifted up. ❋ Apsley Cherry-Garrard (1922)

During the short lull, Jones, Dovers and Hoadley took a sledge for a load of ice from a pressure-ridge rather less than two hundred yards from the hut. ❋ Douglas Mawson (1920)

At 1 P.M. we left the hut, making an east-south-east course to clear a pressure-ridge; altering the course once more to south-east. ❋ Douglas Mawson (1920)

Our burly neighbor, the pressure-ridge, in whose lee we had spent the night, did not make an insuperable obstacle, and in the course of an hour we had made a trail across it, and returned to the igloo for the sledges. ❋ Matthew A. Henson (1888)

We camped at eight P. M., beside a very heavy pressure-ridge as long as a city street and as high as the houses along the street. ❋ Matthew A. Henson (1888)

Another pressure-ridge was surmounted, then a third, and by an hour after the start they had arrived at the first one of Ferriss's flags. ❋ Frank Norris (1886)

"I plugged on in their tracks, till we came to the seal crack which was an old pressure-ridge running many miles S.W. from Pram Point. ❋ Apsley Cherry-Garrard (1922)
