 The current status of Arctic sea ice

AWI Polar 5


Aircraft: AWI Polar5

Institute:Alfred Wegener Institute for Polar and Marine Research (AWI).


Date: 20 March-8 April 2012

Program: Building on the success of the first two campaigns, PAMARCMiP missions are planned for future years, each April when sea ice is near its  maximum extent and thickness: Measure of sea ice thickness (EM-bird surveys).

April is also the period when aerosols and trace gases show important, but poorly understood variations that  influence the surface-atmosphere radiation balance. 


Over the last 30 years, the areal extent of summer sea ice has declined at a rate of 11.2% per decade. Sea ice thickness is the key property for summer minimum sea ice extent. During the last decade, an increased advection of thick multi-year ice that originates from an area north of Greenland, out of the Arctic through the Fram Strait has been observed. A replacement of this old and thick sea ice by much thinner ice might precondition for rapid sea ice retreat in summer. The AWI sea ice group conducted the PAMARCMIP and TIFAX campaigns with the polar research aircraft Polar 5. The objective of the PAMARCMiP (Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project) and TIFAX (Thick Ice Feeding Arctic Export) campaigns was to monitor ice conditions during spring and summer, especially in the main export pathway of the Arctic Ocean. The major aim of these campaigns is the large-scale measurement of sea ice thickness in key Arctic areas.
