The Risk of Synoptic-Scale Arctic Cyclones to Shipping
The risk posed by Arctic cyclones to ships has seldom been quantified due to the lack of publicly available historical Arctic ship track data. This study investigates Automated Identification System (AIS) transponder derived Arctic ship tracks from September 2009 to December 2016. These are analysed...

The risk posed by Arctic cyclones to ships has seldom been quantified due to the lack of publicly available historical Arctic ship track data. This study investigates Automated Identification System (AIS) transponder derived Arctic ship tracks from September 2009 to December 2016. These are analysed with historical synoptic-scale cyclone tracks derived from ERA-5 and reports of past Arctic shipping incidents, to determine the number of ships intersected by the passage of intense Arctic cyclones, and how many resulted in shipping incidents. The number of ships operating in the Arctic has increased year-on-year from 2010 to 2016. The highest density of ships occurs year-round in the Barents Sea. Trans-Arctic shipping transits via the Northern Sea Route and the North-West Passage are limited to summer and autumn months, when sea ice extent has sufficiently retreated from the coastlines.
