The five-year PONAl'vl (polar North Atlantic l\largin: Late Cenozoic Evolution) pr programme was launched by the European Science Foundation in 1989. Its aim was to study the major climate-driven environmental variations in the Norwegian-Greenland (also Nordic) Sea and its continental margins over the last 5 milliion years. The programme has provided substantial new insights into the contrasting behaviour of the ice sheets covering the Svalbard-Barents Sea and East reenland over the last glacial-interglacial cycle in particular. The highly dynamic Svalbard Barents Sea lee Sheet, after reaching the shelf edge during each stadia I, almost vanished during subsequent interstadials.
