TIFAX 2017 Campaign Report: Sea ice thickness measurements with Polar 6 from Station Nord and Alert
Arctic sea ice extent and thickness have undergone dramatic changes in the past decades: Summer sea ice extent has declined at an annual rate of approximately 12.7 % per decade over the satellite record (1978 – present, Meier et al., 2014) and its mean thickness has decreased by 0.58 m +/- 0.07 m pe...

Arctic sea ice extent and thickness have undergone dramatic changes in the past decades: Summer sea ice extent has declined at an annual rate of approximately 12.7 % per decade over the satellite record (1978 – present, Meier et al., 2014) and its mean thickness has decreased by 0.58 m +/- 0.07 m per decade over the period 2000 - 2012 (Lindsay et al., 2015). The thinning of sea ice is accompanied by an increase of ice drift velocity (Spreen et al., 2011), deformation (Rampal et al., 2009) and a decrease of net ice growth rates.
