Analysis of the interannual variability of ice conditions along the route “Sabetta — Murmansk” for the period 1997–2018
The start-up of a plant for liquid gas production in the town of Sabetta (Russia, Yamal Peninsula) requires the creation of a marine transport system for gas shipment. The town is a significant cluster for gas processing and export from South-Tambey Field. The field stock is estimated at more than o...

The start-up of a plant for liquid gas production in the town of Sabetta (Russia, Yamal Peninsula) requires the creation of a marine transport system for gas shipment. The town is a significant cluster for gas processing and export from South-Tambey Field. The field stock is estimated at more than one trillion cubic meters of natural gas. Ice cover is a source of possible accidents with tankers. The accidents can lead to environment contamination. Here we consider analysis of the intra- and inter-annual variability of ice conditions on the navigation route “Sabetta seaport — Kara Gate — Murmansk seaport” for the period of 1997–2018. The route is a path for export of liquid gas. Electronic ice maps of the archives of the Arctic and Antarctic Research Institute (AARI) were processed.
