Information on:

 The current status of Arctic sea ice

2012 Polarstern cruise


Country: Germany

Ship: RV Polarstern

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


Date: August - September 2012

Program:  IceArc 2.5 m - biological stations, ice stations on-top and under the sea ice (ROV, divers, landers, traps).  Ecosystem driven cruise - how ecosystem reacts to changes in ice conditions. Light  distribution etc.  (pelagic-benthic coupling). Mainly in Eurasian basin


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 participated in a Polarstern cruise to the interior Arctic. The major aim of this campaign is the large-scale measurement of sea ice thickness in key Arctic areas.
