Characterization of summer Arctic sea ice morphology in the 135°-175°W sector using multi-scale methods
In summer 2014, sea ice morphological characteristics were investigated in the 135°-175°W sector of the Arctic Ocean using in situ, shipborne, and remote sensing measurements. Sea ice in this sector was deformed and compact compared to previous observations. The average ice area in the region (70°-8...

In summer 2014, sea ice morphological characteristics were investigated in the 135°-175°W sector of the Arctic Ocean using in situ, shipborne, and remote sensing measurements. Sea ice in this sector was deformed and compact compared to previous observations. The average ice area in the region (70°-82.5°N, 135°-175°W) was 7.6 × 105km2for 29 July through 6 September 2014, the fourth largest record between 2003 and 2014. This can be attributed to the enhanced multiyear sea ice inflow from north of the Canadian Arctic Archipelago from September 2013 to August 2014. Multiyear ice coverage in the study region on 30 April 2014 was 55%, which was larger than the values in 2005-2013. During the melt season of 2014, the Arctic Dipole had a positive anomaly, associated with enhanced southerly wind.
