Where the Drill Fell Through

Consolidation and Re-opening of a First-Year Sea-Ice Pressure Ridge Keel across One Winter of Repeated Drilling

A paper from the School of Underlying Conditions drills one first-year pressure ridge in landfast sea ice seven times over 103 days, logging a 17-hole transverse profile for hard, soft and void intervals at each visit. The consolidated layer grew fastest on the windward flank and slowest under the lee drift; a mid-winter deformation event then opened a near-horizontal gap close to the base of the crest's layer, loosened the keel at every depth and cost the crest about three weeks of consolidation.
