Shipping route scenarios PC6 RCP 4.5 2006-2059

0 ratings | 92 views
Optimal September navigation for hypothetical projected trans-arctic shipping routes seeking to cross the Arctic Ocean between the North Atlantic (Rotterdam, The Netherlands and St. John's, Newfoundland) and the Pacific (Bering Strait) during consecutive years 2006--2015 and 2040--2059 as facilitated by ensemble-average GCM projections of sea ice concentration and thickness assuming RCPs 4.5 (medium-low radiative forcing) and 8.5 (high radiative forcing) climate change scenarios. Red lines indicate fastest available trans-Arctic routes for PC6 ships; blue lines indicate fastest available transits for common OW ships. Backdrops indicate period-average sea ice concentrations in 2006--2015 and 2040--2059. Data-source: Smith, L.C. and Stephenson, S.R. (2013). New Trans-Arctic shipping routes navigable by midcentury. Proceedings of the National Academy of Sciences, 110: E1191-E1195. DOI: 10.1073/pnas.1214212110.
