Abstract: A review of consolidation in old ridges is done, ridge keels down to 37 m have been reported in the literature and they are reported to be completely consolidated. But information about physical properties only exists down to a depth dept of 10 m. The models for consolidations in first-year ridges cannot explain a consolidation depth of 37 m. During the summer the ridge keels collapse so that the macro-porosity disappears, meltwater drizzles down from the surface and refreezes, and finally brine is drained from the ridge. These are the most important processes that transform first-year ridges to second-year ridges.
