CryoSat-2 has now finished its 9th winter from October to April of Arctic sea ice thickness observations. No sea-ice thickness production is now paused for the month of May through September since the snow is warming and will soon start to melt. The impact of snow melt on the sea-ice thickness retrieval is poorly understood and the production will resume in October 2019 with the next version of CryoSat-2 data.
In resume, the winter season of 2018/2019 is characterized by above average sea ice thickness in the central Arctic basin. The main driver is a notable positive thickness anomaly of the multi-year ice in the Canadian part of the Arctic Ocean.
